GENERAL INSTRUCTIONS TO BIDDERS

(This page left blank intentionally)
GENERAL INSTRUCTIONS TO BIDDERS
.. 1. SCOPE OF WORK
The work to be done under the contract documents shall consist of the following:
To construct drives, alley approach, sidewalk and curbing at Lubbock Power and Light's Chalker Substation,
74th & Utica Ave.
The contractor shall furnish all labor, superintendence, machinery, equipment and all materials necessary to
complete this project in accordance with contract documents.
2. CONTRACT DOCUMENTS
All work covered by this contract shall be done in accordance with contract documents described in the Gen-
eral Conditions.
All bidders shall be thoroughly familiar with all of the requirements set forth on the contract documents
for the construction of this project and shall be responsible for the satisfactory completion of all work
contemplated by said contract documents.
3. PLANS FOR USE BY BIDDERS
It is the intent of the City of Lubbock that all parties with an interest in submitting a bid on the project
covered by the contract documents be given a reasonable opportunity to examine the documents and prepare a
bid without charge of forfeiture of deposit. The contract documents, may be examined without charge as
noted in the Notice to Bidders.
4. TIME AND ORDER FOR COMPLETION
The construction covered by the contract documents shall be fully completed within 60 (SIXTY) calendar days
from the date specified in the Notice to Proceed issued by the City of Lubbock to the successful bidder.
The Contractor will be permitted to prosecute the work in the order of his own choosing, provided, however,
the City reserves the right to require the Contractor to submit a progress schedule of the work contemplated
by the contract documents. In the event the City requires a progress schedule to be submitted, and it is
determined by the City that the progress of the work is not in accordance with the progress schedule so sub-
mitted, the City may direct the Contractor to take such action as the City deems necessary to insure comple-
tion of the project within the time specified.
5. PAYMENT
All payments due to Contractor shall be made in accordance with the provisions of the General Conditions of
the contract documents.
6. AFFIDAVITS OF BILLS PAID
The City of Lubbock reserves the right, prior to final acceptance of this project to require the Contractor
to execute an affidavit that all bills for labor, materials and incidentals incurred in the construction of
the improvements contemplated by the contract documents have been paid in full and that there are no claims
pending, of which the Contractor has been notified.
-5-
7. MATERIALS AND WORKMANSHIP
The intent of these contract documents is that only materials and workmanship of the best quality and grade
will be furnished. The fact that the specifications may fail to be sufficiently complete in some detail
will not relieve the Contractor of full responsibility for providing materials of high quality and for pro-
tecting them adequately until incorporated into the project. The presence or absence of a representative of
the City on the site will not relieve the Contractor of full responsibility of complying with this provi-
sion. The specifications for materials and methods set forth in the contract documents provide minimum
standards of quality which the Owner believes necessary to procure a satisfactory project.
8. GUARANTEES
All equipment and materials incorporated in the project and all construction shall be guaranteed against de-
fective materials and workmanship. Prior to final acceptance, the Contractor shall furnish to the Owner, a
written general guarantee which shall provide that the Contractor shall remedy any defects in the work, and.
pay for any and all damages of any nature whatsoever resulting in such defects, when such defects appear
within ONE year from date of final acceptance of the work as a result of defective materials or workmanship,
at no cost to the Owner (City of Lubbock).
9. PLANS FOR THE CONTRACTOR
The contractor will be furnished one set of plans and specifications, and related contract documents for his
use during construction. Plans and specifications for use during construction will only be furnished di-
rectly to the Contractor. The Contractor shall then distribute copies of plans and specifications to sup-
pliers, subcontractors or others, as required for proper prosecution of the work contemplated by the Con-
tractor.
10. PROTECTION OF THE WORK
The Contractor shall be responsible for the care, preservation, conservation, and protection of all materi-
als, supplies, machinery, equipment, tools, apparatus, accessories, facilities, and all means of construc-
tion, and any and all parts of the work whether the Contractor has been paid, partially paid, or not paid
for such work, until the date the City issues its certificate of completion to Contractor. The City re-
serves the right, after the bids have been opened and before the contract has been awarded, to require of a
bidder the following information:
(a) The experience record of the bidder showing completed jobs of a similar nature to the one covered by
the proposed contract and all work in progress with bond amounts and percentage completed.
(b) A sworn statement of the current financial condition of the bidder.
(c) Equipment schedule.
11. TEXAS STATE SALES TAX
This contract is issued by an organization which qualifies for exemption provisions pursuant to provisions
of Article 20.04 of the Texas Limited Sales, Excise and Use Tax Act.
The Contractor must obtain a limited sales, excise and use tax permit which shall enable him to buy the ma-
terials to be incorporated into the work without paying the tax at the time of purchase.
-6-
12. PROTECTION OF SUBSURFACE LINES AND STRUCTURES
It shall be the Contractor's responsibility to prosecute the work contemplated by the contract documents in
.� such a way as to exercise due care to locate and prevent damage to all underground pipelines, utility lines,
conduits or other underground structures which might or could be damaged by Contractor during the construc-
tion of the project contemplated by these contract documents. The City of Lubbock agrees that it will fur-
nish Contractor the location of all such underground lines and utilities of which it has knowledge. How-
ever, such fact shall not relieve the Contractor of his responsibilities aforementioned. All such under-
ground lines or structures cut or damaged by Contractor during the prosecution of the work contemplated by
.-. this contract shall be repaired immediately by Contractor to the satisfaction of the City of Lubbock, Texas,
at Contractor's expense.
13. BARRICADES AND SAFETY MEASURES
The contractor shall, at his own expense, furnish and erect such barricades, fences, lights and danger sig-
nals, and shall take such other precautionary measures for the protection of persons, property and the work
as may be necessary.
The Contractor will be held responsible for all damage to the work due to failure of barricades, signs, and
lights to protect it, and when damage is incurred, the damaged portion shall be immediately removed and re-
placed by Contractor at his own cost and expense. The Contractor's responsibility for maintenance of barri-
cades, signs, and lights shall not cease until the date of issuance to Contractor of City's certificate of
acceptance of the project.
14. EXPLOSIVES
r- The use of explosives will not be permitted unless written permission to do so is obtained by the Contractor
from the City. In all cases where written permission is obtained for the use of explosives, the Contractor
shall assume full responsibility for all damage which may occur as a direct or indirect result of the blast-
ing. In addition, in all cases where explosives are authorized to be used, the Contractor shall use utmost
care so as not to endanger life or property and the Contractor shall further use only such methods as are
currently utilized by persons, firms, or corporations engaged in similar type of construction activity.
Explosive materials shall not be stored or kept at the construction site by the Contractor.
In all cases where explosives are to be used during the construction of the project contemplated by this
contract, it shall be the duty of the Contractor to notify each utility company having structures (above or
below the ground) in proximity to the site of the work of Contractor's intention to use explosives, and such
notice shall be given sufficiently in advance to enable the companies to take such steps as they may deem
necessary to protect their property from injury. Such notice, however, shall not relieve the Contractor of
responsibility for any damage resulting from his blasting operations.
15. CONTRACTOR'S REPRESENTATIVE
The successful bidder shall be required to have a responsible local representative available at all times
while the work is in progress under this contract. The successful bidder shall be required to furnish the
name, address and telephone number where such local representative may be reached during the time that the
work contemplated by this contract is in progress.
16. INSURANCE
The Contractor shall not commence work under this contract until he has obtained all insurance as required
in the General Conditions of the contract documents, from an underwriter authorized to do business in the
,s State of Texas and satisfactory to the City. Proof of coverage shall be furnished to the City and written
-7-
notice of cancellation or any material change will be provided ten (10) days in advance of cancellation or
change. All policies shall contain an agreement on the part of the insurer waiving the right to subroga-
tion.
The insurance certificates furnished shall name the City as an additional insured and shall further state
that all subcontractors are named as additional insureds, or in the alternative, shall be accompanied by a
statement from the Contractor to the effect that no work on this particular project shall be subcontracted.
17. LABOR AND WORKING HOURS
Attention of each bidder is particularly called to the schedule of general prevailing rate of per diem wages
included in these contract documents. The wage rate which must be paid on this project shall not be less
than specified in the schedule of general prevailing rates of per diem wages as above mentioned. The
bidders' attention is further directed to the requirements of Article 5159a, Vernon's Annotated Civil
Statutes providing for the payment of the wage schedules above mentioned and the bidder's obligations there-
under. The inclusion of the schedule of general prevailing rate of per diem wages in these contract docu-
ments does not release the Contractor from compliance with any wage law that may be applicable. Construc-
tion work under this contract requiring an inspector will not be performed on weekends or holidays unless
the following conditions exist:
(1) The project being constructed is essential to the City of Lubbock's ability to provide the necessary
service to its citizens.
(2) Delays in construction are due to factors outside the control of the Contractor. The Contractor is
approaching the penalty provisions of the contract and Contractor can show he has made a diligent
effort to complete the contract within the allotted time.
Before construction work requiring an inspector is to be performed on weekends or holidays, the Contractor
must notify the Owner's Representative not Less than three full working days prior to the weekend or holiday
he desires to do work and obtain written permission from the Owner's Representative to do such work. The
final decision on whether to allow construction work requiring an inspector on weekends or holidays will be
made by the Owner's Representative.
In any event, if a condition should occur or arise at the site of this project or from the work being done
under this contract which is hazardous or dangerous to property or life, the Contractor shall immediately
commence work, regardless of the day of the week or the time of day, to correct or alleviate such condition
so that it is no longer dangerous to property or life.
18. PAYMENT OF EMPLOYEES AND FILING OF PAYROLLS
The contractor and each of his subcontractors shall pay each of his employees engaged in work on the project
under this contract in full (less mandatory legal deductions) in cash, or by check readily cashable without
discount, not less often than once each week. The Contractor and each of his subcontractors engaged at the
site of the work shall not later than the seventh day following the payment of wages, file with the Owner's
Representative, or Engineer, a certified, sworn, legible copy of such payroll. This shall contain the name
of each employee, his classification, the number of hours worked on each day, rate of pay, and net pay. The
affidavit shall state that the copy is a true and correct copy of such payroll, that no rebates or deduc-
tions (except as shown) have been made, or will in the future be made from the wages paid as shown thereon.
The Contractor must classify employees according to one of the classifications set forth in the schedule of
general prevailing rate of per diem wages, which schedule is included in the contract documents.
-8-
The Contractor shall forfeit as a penalty to the City of Lubbock on whose behalf this contract is made, 'ten
dollars for each laborer, workman, or mechanic employed for each calendar day, or portion thereof, such
laborer, workman or mechanic is paid less than the wages assigned to his particular classification as set
forth in the schedule of general prevailing rate of per diem wages included in these contract documents.

tion of the Owner's Representative as rendered shall be promptly carried out, and any claim arising there-

Contractor a written decision on all claims of the parties hereto and on all questions which may arise rela-
tive to the execution of the work or the interpretation of the contract, specifications and plans. Should

satisfactory to Owner's Representative. The superintendent shall represent the Contractor in his absence
and all directions given to him shall be binding as if given to the Contractor. Adequate supervision by
competent and reasonable representatives of the Contractor is essential to the proper performance of the
work and lack of such supervision shall be grounds for suspending operations of the Contractor.

tractor and all risk in connection therewith shall be borne by the Contractor.
The Owner or Owner's Representatives will not be responsible for the acts or omissions of the Contractor, or
any subcontractors, or any of his agents or employees, or any other persons performing any of the work.
17. CONTRACTOR'S UNDERSTANDING
It is understood and agreed that the Contractor has, by careful examination, satisfied himself as to the na-
ture and location of the work, the confirmation of the ground, the character, quality and quantity of mate-
rials to be encountered, the character of equipment and facilities needed preliminary to and during the
prosecution of the work, and the general and local conditions, and all other matters which in any way effect
the work under this contract. No verbal agreement or conversation with any officer, agent, or employee of
the Owner, either before or after the execution of this contract, shall effect or modify any of the terms or
obligations herein contained.
18. CHARACTER OF WORKMEN
The Contractor agrees to employ only orderly and competent men, skillful in the performance in the type of
work required under this contract, to do the work; and agrees that whenever the Owner's Representative shall
inform him in writing that any man or men on the work, are, in his opinion, incompetent, unfaithful, or dis-
orderly, such man or men shall be discharged from the work and shall not again be employed on the work with-
out the Owner's Representative's written consent.
19. CONSTRUCTION PLANT
The Contractor shall provide all labor, tools, equipment, machinery and materials necessary in the prosecu-
tion and completion of this contract where it is not otherwise specifically provided that owner shall fur-
nish same, and it is also understood that Owner shall not be held responsible for the care, preservation,
conservation, or protection of any materials, tools, equipment or machinery or any part of the work until it
is finally completed and accepted.

Owner's Representative shall direct, and the sanitary conditions of the grounds in or about such structure
shall at all times be maintained in a manner satisfactory to the Owner's Representative.

servation, shall be constructed and maintained by the Contractor in such manner and at such points as shall
be approved by the Owner's Representative and their use shall be strictly enforced.
-27-
21. OBSERVATION AND TESTING
The Owner or Owner's Representative shall have the right at all reasonable times to observe and test the
work. Contractor shall make necessary arrangements and provide proper facilities and access for such obser-
vation and testing at any location wherever work is in preparation or progress. Contractor shall ascertain
the scope of any observation which may be contemplated by Owner or Owner's Representative and shall give am-
ple notice as to the time each part of the work will be ready for such observation. Owner or Owner's Rep-
resentative may reject any work found to be defective or not in accordance with the contract documents, re-
gardless of the stage of its completion or the time or place of discovery of such errors and regardless of
whether Owner's Observer has previously accepted the work through oversight or otherwise. If any work
should be covered without approval or consent of the Owner, it must, if requested by Owner or Owner's Repre-
sentative, be uncovered for examination at Contractor's expense. In the event that any part of the work is
being fabricated or manufactured at a location where it is not convenient for Owner or Owner's Representa-
tive to make observations of such work or require testing of said work, then in such event Owner or Owner's
Representative may require Contractor to furnish Owner or Owner's Representative certificates of inspection,
testing or approval made by persons competent to perform such tasks at the location where that part of the
-- work is being manufactured or fabricated. All such tests will be in accordance with the methods prescribed
by the American Society for Testing and Materials or such other applicable organization as may be required
by law or the contract documents.
If any work which is required to be inspected, tested, or approved is covered up without written approval or
consent of the Owner or Owner's Representative, it must, if requested by the Owner or Owner's Representa-
tive, be uncovered for observation and testing at the Contractor's expense. The cost of all such inspec-
tions, tests and approvals shall be borne by the Contractor unless otherwise provided herein. Any work
which fails to meet the requirements of any such tests, inspections or approval, and any work which meets
the requirements of any such tests or approval but does not meet the requirements of the contract documents
shall be considered defective. Such defective work shall be corrected at the Contractor's expense.
Neither observations by the Owner or Owner's Representative, nor inspections, tests, or approvals made by
Owner, Owner's Representative, or other persons authorized under this agreement to make such inspections,
tests, or approvals shall relieve the Contractor from his obligation to perform the work in accordance with
the requirements of the contract documents.
22. DEFECTS AND THEIR REMEDIES
It is further agreed that if the work or any part thereof, or any material brought on the site of the work
for use in the work or selected for the same, shall be deemed by the Owner or Owners' Representative as un-
suitable or not in conformity with plans, specification and contract documents, the Contractor shall, after
receipt of written notice thereof from the Owner's Representative, forthwith remove such material and re-
build or otherwise remedy such work so that it shall be in full accordance with this contract. It is fur-
ther agreed that any remedial action contemplated as hereinabove set forth shall be at Contractor's expense.
23. CHANGES AND ALTERATIONS
The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit,
in the line, grade, form dimensions, plans or or materials for the work herein contemplated, or any part
thereof, either before or after the beginning of the construction, without affecting the validity of this
contract and the accompanying bond.
If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the
basis for a claim for damages, or anticipated profits on the work that may be dispensed with. If they in-
crease the amount of work, and the increased work can fairly be classified under the specifications, such
increase shall be paid according to the quantity actually done and at the unit price established for such
work under this contract; otherwise such additional work shall be paid for as provided under Extra Work. In
-28-
case the Owner shall make such changes or alterations as shall make useless any work already done or mate-
rial already furnished or used in said work, then the Owner shall recompense the Contractor for any material
or labor so used, and for any actual loss occasioned by such change, due to actual expenses incurred in
preparation for the work as originally planned.
24. EXTRA WORK
The term "extra work" as used in this contract shall be understood to mean and include all work that may be
required by the owner or Owner's Representative to be done by the Contractor to accomplish any change, al-
teration or addition to the work as shown on the plans and specifications or contract documents and not cov-
ered by Contractor's proposal, except as provided under Changes and Alterations herein.
It is agreed that the Contractor shall perform all extra work under the direction of the Owner's Representa-
tive when presented with a written work order signed by the Owner's Representative; subject, however, to the
right of the Contractor to require written confirmation of such extra work order by the Owner. It is also
agreed that the compensation to be paid to the Contractor for performing said extra work shall be determined
by the following methods:
Method (A) - By agreed unit prices; or
Method (B) - By agreed lump sum; or
Method (C) - If neither Method (A) or Method (B) be agreed upon before the extra work is com-
menced, then the Contractor shall be paid the actual field cost of the work, plus
fifteen (15%) per cent.
In the event said extra work be performed and paid for under Method (C), then the provisions of this para-
graph shall apply and the "actual field cost" is hereby defined to include the cost of all workmen, such as
foremen, timekeepers, mechanics and laborers, materials, supplies, teams, trucks, rentals on machinery and
equipment, for the time actually employed or used on such extra work, plus actual transportation charges
necessarily incurred, together with all expenses incurred directly on account of such extra work, including
Social Security, Old Age Benefits, Maintenance Bonds, Public Liability and Property Damage and Workmen's
Compensation and all other insurances as may be required by law or ordinances or directed by the Owner or
Owner's Representative, or by them agreed to. Owner's Representative may direct the form in which accounts
of the actual field cost shall be kept and records of these accounts shall be made available to the Owner's
Representative. The Owner's Representative may also specify in writing, before the work commences, the
method of doing the work and the type and kind of machinery and equipment to be used; otherwise, these mat-
ters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machin-
ery and equipment shall be determined by using 100%, unless otherwise specified, of the latest Schedule of
Equipment and Ownership Expenses adopted by the Associated General Contractors of America. Where practical,
the terms and prices for the use of machinery and equipment shall be incorporated in the written extra work
order. The fifteen percent (15%) of the actual field cost to be paid to Contractor shall cover and com-
pensate him for his profit, overhead, general superintendence and field office expense, and all other ele-
ments of cost and expense not embraced within the actual field cost as herein defined, save that where the
Contractor's Camp or Field Office must be maintained primarily on account of such Extra Work, then the cost
to maintain and operate the same shall be included in the "actual field cost."
No claim for extra work of any kind will be allowed unless ordered in writing by Owner's Representative. In
case any orders or instructions appear to the Contractor to involve extra work for which he should receive
compensation or an adjustment in the construction time, he shall make written request to the Owner's Repre-
sentative for a written order authorizing such extra work. Should a difference of opinion arise as to what
does or does not constitute extra work or as to the payment therefore, and the Owner's Representative in-
sists upon its performance, the Contractor shall proceed with the work after making written request for
written order and shall keep adequate and accurate account of the actual field cost thereof, as provided
under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbi-
tration as herein below provided.
-29-
p.-
25. DISCREPANCIES AND OMISSIONS
it is further agreed that it is the intent of this contract that all work described in the proposal, the
specifications, plans and other contract documents, is to be done for the prices quoted by the Contractor
and that such price shall include all appurtenances necessary to complete the work in accordance with the
intent of these contract documents as interpreted by Owner's Representative. If the Contractor finds any
discrepancies or omissions in these plans, specifications, or contract documents, he should notify the
Owners' Representative and obtain a clarification before the bids are received, and if no such request is
received by the Owner's Representative prior to the opening of bids, then it shall be considered that the
Contractor fully understands the work to be included and has provided sufficient sums in his proposal to
complete the work in accordance with these plans and specifications. It is further understood that any re-
quest for clarification must be submitted no Later than five days prior to the opening of bids.
26. RIGHT OF OWNER TO MODIFY METHODS AND EQUIPMENT
If at any time the methods or equipment used by the Contractor are found to be inadequate to secure the
quality of work with the rate of progress required under this contract, the Owner or Owner's Representative
may order the Contractor in writing to increase their safety or improve their character and efficiency and
the Contractor shall comply with such order.
If, at any time, the working force of the Contractor is inadequate for securing the progress herein speci-
fied, the Contractor shaLL, if so ordered in writing, increase his force or equipment, or both, to such an
extent as to give reasonable assurance of compliance with the schedule of progress.
27. PROTECTION AGAINST ACCIDENT TO EMPLOYEES AND THE PUBLIC
The Contractor shall take out and procure a policy or policies of Workmen's Compensation Insurance with an
insurance company licensed to transact business in the State of Texas, which policy shall comply with the
Workmen's Compensation laws of the State of Texas. The Contractor shall at all times exercise reasonable

provisions of federal, state and municipaL Laws and building and construction codes. ALL machinery and
equipment and other physical hazards shall be guarded in accordance with the "Manual of Accident Prevention
in Construction" of Associated General Contractors of America, except where incompatible with federal, state
or municipal laws or reguLations. The Contractor, his sureties and insurance carriers shall defend, indem-
nify and save harmless the Owner and all of its officers, agents and employees from all suits, actions, or
claims of any character whatsoever, brought for or on account of any injuries or damages received or sus-
tained by any person or persons or property, on account of any negligent act or fault of the Contractor or
any subcontractor, their agents or employees, i.n the execution and supervision of said contract, and the
project which is the subject matter of this contract, on account of the failure of Contractor or any subcon-
tractor to provide necessary barricades, warning lights, or signs and will be required to pay any judgment
with costs which may be obtained against the Owner or any of its officers, agents, or employees including
attorney's fees.
The safety precautions taken shall be the sole responsibility of the Contractor, in his sole discretion as
an Independent Contractor; inclusion of this paragraph in the Agreement, as well as any notice which may be
given by the Owners or the Owner's Representative concerning omissions under this paragraph as the work pro-
gresses, are intended as reminders to the Contractor of his duty and shall not be construed as any assump-
tion of duty to supervise safety precautions by either the Contractor or any of his subcontractors.

shall remain unpaid, withhold from the unpaid portion of this contract, a sum equal to the amount of such
unpaid indebtedness or may apply the sum so withheld to discharge any such indebtedness.
Any and all communications between any party under this paragraph must be in writing.
30. PROTECTION AGAINST ROYALTIES OR PATENT INVENTION
The contractor shall pay all royalties and license fees, and shall provide for the use of any design, de-
vice, material or process covered by letters patent or copyright by suitable legal agreement with the Paten-
tee or Owner thereof. The Contractor shall defend all suits or claims for infringement of any patent or

Owner shall defend all such suits and claims and shall be responsible for all such loss when a particular
design, device, material or process or the product of a particular manufacturer or manufacturers is speci-
fied or required in these contract documents by Owner; provided, however, if choice of alternate design, de-
vice, material or process is allowed to the Contractor, then Contractor shall indemnify and save Owner harm-
less from any loss on account thereof. If the material or process specified or required by owner is an in-
fringement, the Contractor shall be responsible for such loss unless he promptly gives written notice to the
Owner of such infringement.
31. LAWS AND ORDINANCES
The Contractor shall at all times observe and comply with all federal, state and local laws, ordinances and
regulations, which in any manner effect the contract or the work, and shall indemnify and save harmless the
Owner against any claims arising from the violation of any such laws, ordinances, and regulations, whether
by the Contractor or his employees. If the Contractor observes that the plans and specifications are at
variance therewith, he shall promptly notify the Owners' Representative in writing and any necessary changes
shall be adjusted as provided in the contract for changes in the work. If the Contractor performs any work
knowing it to be contrary to such laws, ordinances, rules and regulations, and without such notice to the
Owner's Representative, he shall bear all costs arising therefrom.
The Owner is a municipal corporation of the State of Texas and the law from which it derives its powers, in-
sofar as the same regulates the objects for which, or the manner in which, or the conditions under which the
Owner may enter into contracts, shall be controlling, and shall be considered as part of this contract to
the same effect as though embodied herein.
32. ASSIGNMENT AND SUBLETTING
The Contractor further agrees that he will retain personal control and will give his personal attention to
the fulfillment of this contract. The Contractor further agrees that subletting of any portion or feature
of the work, or materials required in the performance of this contract, shall not relieve the Contractor
from his full obligations to the Owner, as provided by this contractual agreement.
33. TIME FOR COMPLETION AND LIQUIDATED DAMAGES
It is hereby understood and mutually agreed by and between the Contractor and the Owner, that the date of
beginning and time for completion as specified in the contract of work to be done hereunder are essential
conditions of this contract; and it is further mutually understood and agreed that the work embraced in this
contract shall be commenced on a date to be specified in the Notice to Proceed.
If the Contractor should neglect, fail, or refuse to complete the work within the time herein specified, or
any proper extension thereof granted by the Owner, then the Contractor does hereby agree as part of the con-
sideration for the awarding of this contract, the Owner may withhold permanently from Contractor's total
compensation, the sum of $5O.00 (FIFTY DOLLARS) PER DAY, not as a penalty, but as liquidated damages for the
-33-
breach of the contract as herein set forth for each and every calendar day that the Contractor Shall be in
default after the time stipulated for completing the work.
It is expressly understood and agreed, by and between Contractor and the Owner, that the time for the com-
pletion of the work described herein is reasonable time for the completion of the same, taking into consid-
eration the average climatic change and conditions and usual industrial conditions prevailing in this .Local-
ity.
The amount is fixed and agreed upon by and between the Contractor and the Owner because of the impractica-
bility and extreme difficulty in fixing.and ascertaining actual damages the Owner would in such event sus-
tain, and the amount is agreed to be damages the Owner would sustain and shall be retained by the Owner from
current periodical estimates for payments or from final payment.
it is further agreed and understood between the Contractor and Owner that time is of the essence of this
contract.
34. TIME AND ORDER OF COMPLETION
It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Con-
tractor shall be allowed to prosecute his work at such time and sessions, in such order of precedence, and
in such manner as shall be most conductive to economy of construction; provided, however, that the order and
time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in
accordance with this contact, the plans and specifications, and within the time of completion designated in
the proposals; provided, also, that when the Owner is having other work done, either by contract or by his
own force, the Owner's Representative may direct the time and manner of constructing work done under this
contract so that conflicts will be avoided and the construction of the various works being done for the
Owner shall be harmonized.
The Contractor shall submit, at such times as may reasonably be requested by the Owner's Representative,
schedules which shall show the order in which the Contractor proposes to carry on the work, with dates at
... which the Contractor will start the several parts of the work and estimated dates of completion of the sev-
eral parts.
35. EXTENSION OF TIME
The Contractor agrees that he has submitted his proposal in full recognition of the time required for the
completion of this project, taking into consideration the average climatic range and industrial conditions
prevailing in this locality, and has considered the liquidated damage provisions of paragraph 33 hereinabove
set forth and that he shall not be entitled to, nor will he request, an extension of time on this contract,
except when his work has been delayed by an act or neglect of the Owner, Owner's Representative, employees
of the Owner or other contractors employed by the owner, or by changes ordered in the work, or by strike,
walk -outs, acts of God or the public enemy, fire or flood. The Contractor may apply in writing for an ex-
tension of time, submitting therewith all written justification as may be required by Owner's Representative
for such an extension as requested by Contractor. The Owner's Representative within ten (10) days after re-
ceipt of a written request for an extension of time by the Contractor supported by all requested docu-
mentation shall then submit such written request to the City Council of the City of Lubbock for their con-
sideration. Should the Contractor disagree with the action of City Council on granting an extension of
time, such disagreement shall be settled by arbitration as hereinafter provided.
36. HINDRANCE AND DELAYS
In executing the contract agreement, the Contractor agrees that in undertaking to complete the work within
the time herein fixed, he has taken into consideration and made allowances for all hindrances and delays in-
cident to such work, whether growing out of delays in securing material or workmen or otherwise. No charge
-34-
shall be made by the Contractor for hindrance or delays from any cause during the progress of any part df
the work embraced in this contract except where the work is stopped by order of the Owner or Owner's
Representative for the Owner's convenience, in which event, such expense as in the judgment of the Owner's
Representative that is caused by such stoppage shall be paid by Owner to Contractor.
37. QUANTITIES AND MEASUREMENTS
No extra or customary measurements of any kind will be allowed, but the actual measured or computed length,
area, solid contents, number and weight only shall be considered, unless otherwise specifically provided.
In the event this contract is let on a unit price basis, then Owner and Contractor agree that this contract,
including the specifications, plans and other contract documents are intended to show clearly all work to be
done and material to be furnished hereunder. Where the estimated quantities are shown for the various
classes of work to be done and material to be furnished under this contract, they are approximate and are to
be used only as a basis for estimating the probable cost of the work and for comparing their proposals of-
fered for the work. It is understood and agreed that the actual amount of work to be done and the materials
to be furnished under this contract may differ somewhat from these estimates, and that where the basis for
payment under this contract is the unit price method, payment shall be for the actual amount of work done
and materials furnished on the project.
38. PROTECTION OF ADJOINING PROPERTY
The Contractor shall take proper means to protect the adjacent or adjoining property or properties in any
way encountered, which may be injured or seriously affected by any process of construction to be undertaken
under this agreement, from any damage or injury by reason of said process of construction; and he shall be
Liable for any and all claims for such damage on account of his failure to fully protect all adjacent
property. The Contractor agrees to indemnify, save and hold harmless the Owner against any claim or claims
for damages due to any injury to any adjacent or adjoining property, arising or growing out of the perfor-
mance of this contract, but such indemnity shall not apply to any claim of any kind arising out of the exis-
tence or character of the work.
39. PRICE FOR WORK
In consideration of the furnishing of all necessary labor, equipment and material and the completion of all
work by the Contractor, and on the delivery of all materials embraced in this contract in full conformity
with the specifications and stipulations herein contained, the owner agrees to pay the Contractor the price
set forth in the proposal attached hereto, which has been made a part of this contract, and the Contractor
hereby agrees to receive such price in full for furnishing all materials and all labor required for the
aforesaid work, also, for all expenses incurred by him and for well and truly performing the same and the
whole thereof in the manner and according to this agreement, the attached specifications, plans, contract
documents and requirements of Owner's Representative.
40. PAYMENTS
No payments made or certificates given shall be considered as conclusive evidence of the performance of the
contract, either wholly or in part, nor shall any certificate or payment be considered as acceptance of de-
fective work. Contractor shall at any time requested during the progress of the work furnish the Owner or
Owner's Representative with a verifying certificate showing the Contractor's total outstanding indebtedness
in connection with the work. Before final payment is made, Contractor shall satisfy Owner, by affidavit or
otherwise, that there are no outstanding liens against Owner's premises by reason of any work under the con-
tract. Acceptance by Contractor of final payment of the contract price shall constitute a waiver of all
claims against Owner which have not theretofore been timely filed as provided in this contract.
-35-
41. PARTIAL PAYMENTS
On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an applica-
tion for partial payment. Owner's Representative shall review said application for partial payment and the
progress of the work made by the Contractor and if found to be in order shall prepare a certificate for par-
tial payment showing as completely as practical the total value of the work done by the Contractor up to and
including the last day of the preceding month; said statement shall also include the value of all sound ma-
terials delivered on site of the work that are to be fabricated into the work.
The Owner shall then pay the Contractor on or before the fifteenth day of the current month the total amount
of the Owner's Representative's Certificate of Partial Payment, less 5% of the amount thereof, which 5%
shall be retained until final payment, and further, less all previous payments and all further sums that may
be retained by Owner under the terms of this agreement. It is understood, however, that in case the whole
work be near to completion, and this fact is certified to by Owner's Representative and some unexpected and
some unusual delay occurs due to no fault or negligence on the part of the Contractor, the Owner may upon
written recommendation of Owner's Representative pay a reasonable and equitable portion of the retained per-
centage due Contractor.
42. FINAL COMPLETION AND ACCEPTANCE
Within thirty-one (31) days after the Contractor has given the Owner's Representative written notice that
the work has been completed or substantially completed, the Owner's Representative and the Owner shall in-
spect the work and within said time, if the work be found to be completed or substantially completed in ac-
cordance with the contract documents, the Owner's Representative shall issue to the Owner and Contractor his
certificate of completion, and thereupon it shall be the duty of the Owner within thirty-one (31) days to
issue a certificate of acceptance of the work to the Contractor.
43. FINAL PAYMENT
Upon the issuance of the certificate of completion, the Owner's Representative shall proceed to make final
measurement and prepare a final statement of the value of all work performed and materials furnished under
the terms of the agreement, and shall certify same to the Owner, who shall pay to the Contractor on or be-
fore the 31st day after the date of certificate of completion, the balance due Contractor under the terms of
this agreement, provided he has fully performed his contractual obligations under the terms of this con-
tract; and said payment shall become due in any event upon said performance by the Contractor. Neither the
certificate of acceptance nor the final payment, nor any provisions in the contract documents shall relieve
the Contractor of the obligation for fulfillment of any warranty which may be required in the special condi-
tions (if any) of this contract or required in the specifications made a part of this contract.
44. CORRECTION OF WORK BEFORE FINAL PAYMENT FOR WORK
Contractor shall promptly remove from Owners' premises all materials condemned by the Owner's Representative
on account of failure to conform to the contract, whether actually incorporated in the work or not, and Con-
tractor shall at his own expense promptly replace such condemned materials with other materials conforming
to the requirements of the contract. Contractor shall also bear the expense of restoring all work of other
contractors damaged by any such removal or replacement. If Contractor does not remove and replace any such
condemned work within a reasonable time after a written notice by the Owner or the Owner's Representative,
Owner may remove and replace it at Contractor's expense.
45. CORRECTION OF WORK AFTER FINAL PAYMENT
Neither the final payment nor certificate nor any provision in this contract shall relieve the Contractor of
responsibility for faulty materials or workmanship, and he shall remedy any defects due thereto and pay for
any damage to other work resulting therefrom, which shall appear within a period of one (1) year from the
-36
date of substantial completion. The Owner or the Owner's Representative shall give notice of observed de-
fects with reasonable promptness.
46. PAYMENT WITHHELD
The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole.or part of any
certificate to such extent as may be necessary to protect himself from loss on account of:
(a) Defective work not remedied.
(b) Claims filed or reasonable evidence indicating possible filing of claims.
(c) Failure of the Contractor to make payments promptly to subcontractors or for materials or labor.
(d) Damage to another contractor.
When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner,
which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of
them.
47•. TIME OF FILING CLAIMS
It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the
Contractor shall be in writing and filed with the Owner's Representative within fifteen (15) days after the
Owner's Representative has given any directions, order or instruction to which the Contractor desires to
take exception. The Owners' Representative shall reply to such written exceptions by the Contractor and
render his final decision in writing. In case the Contractor should appeal from the decision of the Owner's
Representative, any demand for arbitration shall be filed with the Owner's Representative and the Owner in
writing within ten (10) days after the date of delivery to Contractor of the final decision of the Owner's
Representative. It is further agreed that final acceptance of the work by the Owner and the acceptance by
the Contractor of the final payment shall be a bar to any claim by either party, except where noted other-
wise in the contract documents.
48. ARBITRATION
All questions of dispute under this agreement shall be submitted to arbitration at the request of either
party to the dispute. The parties may agree upon one arbitrator, otherwise, there shall be three; one named
in writing by each party and the third chosen by the two arbiters selected; or if the arbiters fail to se-
lect a third within ten (10) days, he shall be chosen by the District Judge, 72nd Judicial District of
Texas. Each arbiter shall be a resident of the City of Lubbock. Should the party demanding arbitration
fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the de-
cision of the Owner's Representative shall be final and binding on him. Should the other party fail to
choose an arbiter within ten (10) days, the Owner's Representative shall appoint such arbiter. Should ei-
ther party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the
arbiters are empowered by both parties to take Ex Parte Proceedings.
The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the
contract, unless either or both parties shall appeal within ten (10) days from date of the award by the ar-
biters, and it is hereby agreed that each party shall have the right of appeal and all proceedings shall be
according to and governed by Arbitration Statutes of Texas, being Article 224, et seq., Vernon's Annotated
Civil Statutes. THE DECISION OF THE ARBITERS UPON ANY QUESTION SUBMITTED TO ARBITRATION UNDER THIS CONTRACT
SHALL BE A CONDITION PRECEDENT TO ANY RIGHT OF LEGAL ACTION.
-37-
The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sus-
tained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the
appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The ar-
biters shall fix their own compensation, unless otherwise provided by agreement, and shall assess the costs
and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writ-
ing and shall not be open to objection on account of the form of proceedings or award.
49. ABANDONMENT BY CONTRACTOR
In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written
notification from the Owner or the Owners Representative, or if the Contractor fails to comply with the or-
ders of the Owner's Representative, when such orders are consistent with this contract, this Agreement, or
the Specifications hereto attached, then the Surety on the bond shall be notified in writing and directed to
complete the work and a copy of said notice shall be delivered to the Contractor.
After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery,
--� equipment, tools, materials or supplies then on the job, but the same, together with any materials and
equipment under the contract for work, may be held for use on the work by the Owner or the Surety of the
Contractor, or another contractor, in completion of the work; and the Contractor shall not receive any
rental or credit therefore (except when used in connection with Extra Work, where credit shall be allowed as
provided for under paragraph 24 of this contract); it being understood that the use of such equipment and
materials will ultimately reduce the cost to complete the work and be reflected in the final settlement.
In case the Surety should fail to commence compliance with the notice for completion hereinbefore provided
for within ten (10) days after service of such notice, then the Owner may provide for completion of the work
in either of the following elective manners:
(a) The Owner may employ such force of men and use of machinery, equipment, tools, materials and sup-
plies as said owner may deem necessary to complete the work and charge the expense of such labor,
machinery, equipment, tools, materials and supplies to said Contractor, and the expense so charged
shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at
any time become due to the Contractor under and by virtue of this Agreement. In case such expense
is less than the sum which would have been payable under this contract, if the same had been
com-pleted by the Contractor, then said Contractor shall receive the difference. In case such expense
is greater than the sum which would have been payable under this contract, if the same had been com-
pleted by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess
to the Owner; or
(b) The Owner, under sealed bids, after notice published as required by law, at least twice in a newspa-
per having a general circulation in the County of location of the work, may let the contract for the
completion of the work under substantially the same terms and conditions which are provided in this
contract. In case of any increase in cost to the Owner under the new contract as compared to what
would have been the cost under this contract, such increase shall be charged to the Contractor and
the Surety shall be and remain bound therefore. However, should the cost to complete any such new
contract prove to be less than that which would have been the cost to complete the work under this
contract, the Contractor or his Surety shall be credited therewith.
When the work shall have been substantially completed, the Contractor and his Surety shall be so notified
and certificates of completion and acceptance, as provided in paragraph 42 hereinabove set forth, shall be
issued. A complete itemized statement of the contract accounts, certified to by owner's Representative as
being correct shall then be prepared and delivered to Contractor and his Surety, whereon the Contractor or
his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement within
30 days after the date of certificate of completion.
-38-
In the event the statement of accounts shows that the cost to complete the work is less than that which'
would have been the cost to the Owner had the work been completed by the Contractor under the terms of this
contract, or when the Contractor and/or his Surety shall pay the balance shown to be due by them to the
Owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be
turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the contract
price, and the Contractor and/or his Surety fail to pay the amount due the Owner within the time designated
hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the
work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the
Contractor and his Surety at the respective addresses designated in this contract; provided, however, that
actual written notice given in any manner will satisfy this condition. After mailing, or other giving of
such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the
duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date
of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net
sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either
public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machin-
ery, equipment, tools, materials, or supplies which remain on the *jobsite and belong to persons other than
the Contractor or his Surety, to their proper owners.
50. ABANDONMENT BY OWNER
In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply
with said terms within ten (10) days after written notification by the Contractor, then the Contractor may
suspend or wholly abandon the work, and may remove therefrom all machinery, tools, and equipment, and all
materials on the ground that have not been included in payments to the Contractor and have not been incorpo-
rated into the work. Thereupon, the Owner's Representative shall make an estimate of the total amount
earned by the Contractor, which estimate shall include the value of all work actually completed by said Con-
tractor at the prices stated in the the attached proposal, the value of all partially completed work at a
fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided
for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Con-
tractor to carry the whole work to completion, and which cannot be utilized. The Owner's Representative
shall then make a final statement of the balance due the Contractor by deducting from the above estimate all
previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this
Agreement, and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days
after the date of the notification by the Contractor the balance shown by said final statement as due the
Contractor, under the terms of this Agreement.
51. BONDS
The successful bidder shall be required to furnish a performance bond and payment bond in accordance with
Article 5160, Vernon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the
event said contract price exceeds $25,000.00. If the contract price does not exceed $25,000.00, the statu-
tory bonds will not be required. All bonds, if required, shall be submitted on forms supplied by the Owner,
and executed by an approved Surety Company authorized to do business in the State of Texas. And it is fur-
ther agreed that this contract shall not be in effect until such bonds are so furnished.
52. SPECIAL CONDITIONS
In the event special conditions are contained herein as part of the contract documents and said special con-
ditions conflict with any of the general conditions contained in this contract, then in such event the
special conditions shall control.
-39-
53. LOSSES FROM NATURAL CAUSES
Unless otherwise specified herein, all loss or damage to the Contractor arising out of the nature of the
work to be done, or from the action of the elements, or from any unforeseen circumstance and the prosecution
of the same, or from unusual obstructions or difficulties which may be encountered in the prosecution of the
work, shall be sustained and borne by the Contractor at his own cost and expense.
54. INDEPENDENT CONTRACTOR
Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and au-
thority to direct, supervise, and control his own employees and to determine the method of the performance
of the work covered hereby. The fact that the Owner or Owner's Representative shall have the right to ob-
serve Contractor's work during his performance and to carry out the other prerogatives which are expressly
reserved to and vested in the Owner or Owner's Representative hereunder, is not intended to and shall not at
any time change or effect the status of the Contractor as an independent contractor with respect to either
the Owner or Owner's Representative or to the Contractor's own employees or to any other person, firm, or
corporation.
55. CLEANING UP
The Contractor shall at all times keep the premises free from accumulation of debris caused by the work, and
at the completion of the work he shall remove all such debris and also his tools, scaffolding, and surplus
materials and shall leave the work room clean or its equivalent. The work shall be left in good order and
condition. In case of dispute Owner may remove the debris and charge the cost to the Contractor.

Details of Construction
1. Concrete
A. Curb and Gutter (Class A -Concrete)_
Descrintion
This item shall consist of Portland Cement 30" concrete
curb and gutter or 30" separate gutter as shown on the
plans or as directed by the engineer, and shall be
constructed of Class A concrete. Included in the curb and
gutter item is the subgrade preparation and the filling and
shaping of the area behind the curb.
(1) Curb Openings
Separate gutter sections will be placed only across alleys
and driveways presently in use or where definitely planned
for future property improvements. It shall be the
responsibility of the contractor to contact the property
-- owner and determine the proper location of driveways before
curb and gutter is constructed. All gutters across new or
proposed driveways must meet the requirements set forth in
the City Sidewalk and Driveway Regulations, Ordinance
Number 1466 and amendments thereto and gutters across
existing driveways will be required to conform to said
regulations if no hardship to the existing property
improvements is involved. In any event, all curb and gutter
to be poured must have the engineer's approval as to
driveway widths and location, in addition to the section,
r. and line and grade approval before any pour is started on
any curb and gutter unit.
(2) Excavation and Subgrading (See Section V-2)
Excavation for the curb and gutter shall be made with the
excavation of the entire street. The excavation shall be
done to the lines and grades set by the engineer and in
such a manner as to require a maximum 1/2" (inch) of fill
to bring the subgrade to the correct elevation. Subgrade
that is undercut 1" (one inch) or more shall be brought to
the correct elevation by scarifying, wetting, disking,
blading, rolling and compacting to 95% Standard Proctor
Density (A.S.T.M. D-698) with pneumatic rolling to correct
elevation prior to setting forms. Before completion of curb
and gutter, all traffic signs and street name markers found
in the way of paving will immediately be relocated behind
the proposed curb and gutter by the Contractor.
M
(3) Setting Forms
Forms for concrete and gutter shall be set to the lines and
grades established by the engineer after the subgrade has
been prepared. The forms shall be held together and in
place in such a manner that they will not move during the
placing and working of the concrete. The forms shall be
cleaned and oiled prior to pouring concrete. Face forms and
construction joints (removable metal plates) shall be set
to hold the concrete for the curb in place until it is to
be finished.
Forms for radii shall be set in the same manner as the
straight forms except that no face form will be required if
a true section is obtained by other methods. The radii
forms shall be set in such a manner that the curve will be
true.
(4) Placement (Including Making Joints)
Sufficient concrete shall be placed to allow for shrinkage
and extra material for finishing, and the concrete shall be
floated and troweled to the approximate section, and only
after the concrete receives a partial set shall the face
forms be removed. The section shall then be shaped to the
true cross-section by the use of a metal -screed which is
shaped to the true cross-section.
A "mule" screed shall be used only to shape to true cross-
section when topping material is provided and pushed along
on the front edge of the mule.
Curb and gutter shall be constructed with an expansion
joint at the tangent point of each return at intersections
and at intervals of no more than forty (40) feet between
the intersections. Forty feet intervals may be waived if
curb and gutter machine is used. Expansion joints shall be
of the material hereinbefore specified. Construction joints
formed by removable metal plates (templates) accurately
shaped to the cross-section of the curb and gutter shall be
located at the mid=point of each section between expansion
joints or as directed by the engineer. Contraction joints
shall be placed at ten foot intervals. All joints shall be*
perpendicular to the surface of the concrete and to the
axis of the section.
(5) Finishing
A ten (10.) foot metal "straight -edge" shall be used to
strike the flow line to grade, continuously along the flow
line of the Gutter_
four (4) foot spirit level to assure the continuous grade
down the flow -line the length of the gutter.
Curb and gutter shall be finished uniformly by wood
trowelling to an accurate cross-section. Extra water will.
not be added for finishing. The final finish will be
accomplished with a brush, the last stroke being one from
the back of curb to the lip of gutter. Both sides of all
joints, the lip of gutter, and,the back edge of the curb
�- shall be finished with a 1/4" radius edging tool before the
final brushing. Curves at the top and bottom of the section
shall present a uniform appearance without "waves" in the
face of the curb or "pockets" in the gutter.
Concrete shall not be poured during sand storms. Concrete
shall be protected to maintain temperature of not less than
�^ 50 degrees F. for five days after placement. If aggregate
and water are heated, they shall not be heated above 90
degrees F. Concrete shall not be placed when the ambient
temperature is less than 40 degrees F. It shall be the
responsibility of the Contractor to anticipate as nearly as
possible changes in weather conditions which would affect
the placement and protection of the concrete, and be
prepared to protect freshly placed concrete when sudden
changes in the weather make such protection necessary.
(6) Removing Forms
Special care is required of the Contractor in his removing
of pins and of forms. Pins shall be pulled from the ground
to free forms. If hammering is found to be necessary, a
Tight, one (1) pound hammer shall be used. The contractor
shall not place forms or pins on newly finished concrete.
Loading and unloading of forms from a truck shall be
executed by two workmen. It is the duty of the Contractor
to remove any warped forms found in any section of forms,
before it is poured. When forms are pointed out as
defective, those forms shall then be removed from the job
site and not returned until they have been inspected by the
Engineer.
(7) Machine Laid Curb and Gutter
Class A concrete shall be used for machine laid curb and
gutter. The slump of the concrete shall be as directed by
the Engineer. Reinforcing steel, if required, shall conform
to Section 3 under Materials of Construction.
The curb and gutter shall be laid by an extrusion machine
._..__._..approved by the Engineer. Immediately prior to placing the
curb and gutter, the previously approved foundation shall
be thoroughly cleaned.
The line for top of curb shall be maintained from a
guideline set by the Contractor from survey marks
established by the Engineer. Curb outline shall strictly
conform to the details shown on the plans.
The approved mix shall be fed into the machine in such a
manner and at such consistency that the finished curb`will
present a well compacted mass with a surface free from
voids and honeycombs and true to established shape, line,
and grade.
Additional surface finishing shall be performed immediately
after extrusion. Extra water will not be added for
finishing. Unless otherwise specified by the Engineer,
joints shall be constructed as follows: Expansion joints
shall be located at each end radius at intersections and
alley returns and at the beginning of the pour, and dummy
grooved joints shall be spaced at 10 foot intervals between
the expansion joints.
(8) Curing
All concrete work shall be covered with heavy water -proof
type paper to prevent loss of moisture and to prevent
direct sunlight from striking the concrete, as soon as it
has set sufficiently enough to prevent marking.
In lieu of this method of curing, the curb and gutter may
be cured by applying a liquid membrane coating to all
exposed surfaces, provided such material and method is
first approved by the Engineer.
(9) Filling Behind Curb
After the forms are removed and the concrete has cured, the
contractor shall fill the area behind the curb with top
soil. The area between the sidewalk and the curb or
property line and curb, if no sidewalk exists, shall be
leveled and sloped toward the curb in a manner satisfactory
to the property owner and/or Engineer. Fill should be done
prior to dumping caliche.
(10) Replacement of Damaged Curb and Gutter or Gutter

(101 Mechanical vibratory Equipment
All concrete placed for pavement shall be consolidated by
approved mechanical vibrators designed to vibrate the
concrete internally. The internal type will be used for
full -depth placement. Vibratory members shall ex -:and across
the pavement practically to, but shall noz come :n contact
with the side forms. Mechanically operwued vibra_ors shall
be operated in such a manner as to not-nterfere with the
transverse or longitudinal joints.
Separate vibratory units shall be operated at sLffficiently
close intervals to provide uniform vibration and -
consolidation to the.entire width of th e paveme:-=. The
frequency in air of the internal spud type vibra_ory units
shall be not less than 8,000 cycles per minute and not less
than 5,000 cycles per minute for tube types and ::he method
of operation shall be as directed by the Engineer. The
Contractor shall have a satisfactory tachometer available
for checking the vibratory elements.
The pavement vibrators shall not be used to level or spread
the concrete but shall be used only for purposes of
consolidation. The vibrators will not be operated where the
surface of the concrete, as spread, is below the elevation
of the finished surface of the pavement, except -or the
first lift of concrete where the double strike cff method
of placement is employed, and the vibrators shall not be
operated for more than 15 seconds while the mac4ne upon
which they are installed is standing still.
Approved hand manipulated mechanical vibrators shall be
furnished in the number required for provision c= proper
consolidation of the concrete along forms, at jc-nts and in
areas not covered by mechanically controlled vibrators.
These vibrators shall be sufficiently rigid to insure
control of the operation position of the vibrating head.
Complete and satisfactory consolidation of the concrete
pavement is a most important requirement of this
specification. Cores taken shall be carefully examined for
voids, honeycombing or other evidence of incomplete
consolidation. If such evidence is present, charges in -the
consolidation procedures and/or equipment will be made to
insure satisfactory consolidation.
(11) Finishing
Machine- Finishing. All concrete pa-lf•ment shall be finished
mechanically with approved power-dri'len machines, except as
herein provided. Hand -finishing will be permitted on the
transition from a crowned section to a superelevated
section without crown or curves, and on straight line
superelevation sections less than 300 feet in length. Hand -
finishing will also be permitted on that portion of a
widened pavement outside the nor^al pavement width, on
sections where the pavement width is not uniform, or
required monolithic widths are greater than that of
available finishing machines.
Machine -finishing of pavement shall include the use of
power -driven spreaders, power -driven vibrators, power -
driven transverse strike -off, and screed, or such alternate
equipment as may be substituted.and approved by.the
Engineer.
All concrete shall be consolidated by a mechanical
vibrator. As soon as the concrete has been spread between
the forms, the approved mechanical vibrator shall be
operated to consolidate the concrete and remove all voids.
Hand -manipulated vibrators shall be used for areas.not
covered by the mechanical vibratory unit.
The transverse finishing machine shall first be operated to
compact and finish the pavement to the required section and
grade, without surface voids. The machine shall be operated
over each area as many times and at such intervals as
directed. At least two trips will be required and the last
trip over a given area shall be a continuous run of not
less than 40 feet. After completion of finishing with the
transverse finishing machine a transverse drag float may be
used.
The consistency of the concrete as placed should allow the
completion of all finishing operations without the addition
of water to the surface. When field conditions are such
that additional moisture is needed for the final concrete
surface finishing operation, the required water shall be
applied to the surface by fog spray only and shall be held
to a minimum.
After finishing is complete and the concrete still
workable, the surface shall be tested for trueness with an
approved 10-foot steel straightedge. The straightedge shall
be operated from the side of the pavement, placed parallel
to the pavement centerline and passed across the slab to
reveal any high spots or depression. The straightedge shall
be advanced along the pavement in successive stages of not
more than one-half its length. Practically perfect contact
of the straightedge with the surface will be required, and
the pavement shall be leveled to this condition, in order
to insure conformity with the surface test required below,
after the pavement has fully hardened. Any correction of
the surface required shall be accomplished by adding
concrete if required and by operating the longitudinal
---- float over the area. The surface test with the straightedge
shall then be repeated.
For one -lane pavement placement and uniform widening, the
equipment for machine -finishing of concrete pavement shall
be as directed by the Engineer but shall not exceed the
requirements of these specifications.
After completion of the straightedge operation, as soon as
construction operations permit, texture shall be applied
with 1/8-inch wide metal tines with clear spacing between
the tines being not less than 1/4 inch nor more than 1/2
�^ inch. If approved by the Engineer, other equipment and
methods may be used, provided that a surface texture
meeting the specified requirements is obtained. The texture
shall be applied transversely. It is the intent that the
average texture depth resulting from the number of tests
directed by the Engineer be not less than 0.060 inch with a
minimum texture depth of 0.050 inch for any one test when
tested in accordance with Test Method Tex-436-A. Should the
texture depth fall below that intended, the finishing
procedures shall be revised to produce the desired texture.
(12) Proportioning of Concrete
Concrete shall be composed of Portland cement, fine
aggregate, coarse aggregate, mineral filler and/or
admixture if used and water, mixed in proportions as
approved by the Engineer in the mix design as submitted by
a commercial laboratory and in the manner set forth in this
specification. On the basis of job and laboratory
investigations of the proposed materials, the Engineer will
fix the proportions by weight of water, coarse aggregate,
fine aggregate, cement, admixture and mineral filler where
required, in order to produce concrete of the specified
strength and workability.
(13) Concrete Strength
The concrete mix will be designed with the intention of
producing a minimum average flexural strength (Modulus of
rupture) of 600 pounds per square inch and compressive
strength of 3000 psi at 7 days and/or a 28 day compressive
strength of 3,600 pounds per square inch. The coarse
aggregate factor (dry, loose volume of coarse aggregate per
unit volume of concrete) shall not exceed 0.85. Unless
�-- otherwise shown on plans the concrete shall contain not
less than six sacks of cement per cubic yard of concrete.
The water -cement ratio (net gallons of water per sack of 94
pound cement) shall not exceed 6.0 gallon/sack. Concrete
specimens shall be prepared, cured and tested as outlined
in THD Bulletin C-11.
strength will be selected by the Engineer. The Contractor
may at any time present in writing a suggested mix design
and the Engineer will make the tests necessary to determine
its acceptability under these specification requirements.
For mixing the concrete to be used in making the
preliminary test specimens, the Contractor shall furnish
and operate the mixer approved for use on this project. A
minimum one cubic yard batch shall be mixed or a batch of
sufficient size to afford proper mixing, whichever is the
greater. In lieu of the above mixer and procedure, the
Contractor may furnish a portable mixer of sufficient rated
capacity to mix a minimum three -sack batch; in which case,
the batch mixed for the preliminary test shall not be less
than the rated capacity of the mixer furnished.
No additional compensation will be allowed for equipment,
materials or labor involved in making preliminary test
specimens.
After the mix proportions and water -cement ratio required
to produce concrete of the specified strength have been
determined, placing of the concrete may be started.
Type I cement shall have a specified surface area within a
range of 1,600 to 1,900 square centimeters per gram. A
change in the specific surface of the cement of more than
100 square centimeters per gram may require a new mix
design.
(16) Subarade and Forms
Preparation of subgrade.
Rolling and sprinkling shall be performed when and to the
extent directed, and the roadbed shall be completed to or
above the plane of the typical sections shown on the plans.
and the lines and grades established by the Engineer.
Drainage of the roadbed shall be maintained at all times.
Sealed or treated-subgrade cut in the preparation of the
subgrade or setting of pavement forms shall be resealed or
the subgrade restored to the original conditions as
directed by the Engineer. See Section V-2.
The subgrade shall be maintained in a smooth, compacted
condition in conformity with the required section and
established grade until the pavement is placed and shall be
kept thoroughly wetted down sufficiently in advance of
placing any pavement to insure its being in a firm and
moist condition for at least 2 inches below the prepared
(14) Workability of Concrete
Concrete shall be uniformly plastic, cohesive and workable.
Workable concrete is defined as concrete which can be
placed without honeycomb and without voids in the surface.
-- of the pavement. Workability shall be obtained without
producing a condition such that free water appears on the
surface of the slab when being finished as specified. Where
water appears on the surface of the concrete after
finishing and this condition cannot be corrected by
reasonable adjustment in the batch design, the bleeding
will be immediately corrected by one of the following
measures or a combination of two or more of the following
listed measures:
(a) Redesign of the batch
(b) Addition of mineral filler to fine aggregate
r^' (c) Increase of cement content
In the event that the measures taken do not eliminate the
bleeding immediately, concrete placement operations will be
suspended, as directed by the Engineer, and will remain
suspended, until such time as additional trial mixes
demonstrate that a non -bleeding batch design has been
achieved. Failing to achieve a satisfactory laboratory
batch design the Contractor will be required to use
different materials and to submit samples thereof for
additional trial mixes and pilot beams as specified in THD
Bulletin C-11.
The mix will be designed with the intention of producing
concrete which will have a slump of 1-1/2 inches when
tested in accordance with THD Bulletin C-11. The slump
shall not be less than 1 inch nor more than 3 inches.
(15) Mix Design
�., Prior to the beginning of the concrete placement, and
thereafter before any change in source or characteristics
of any of the ingredients except mineral filler, sufficient
compression tests using various quantities of cement and -
aggregates proposed for use shall be supplied the Engineer
for consideration.
Mixes will be designed and made in sufficient number to
represent a wide range of water -cement ratios. These mixes
shall comply with the requirements herein prescribed for
From these preliminary tests the water -cement
ratio required to produce concrete of the specified
surface. Sufficient subgrade shall always be prepared in
advance to insure satisfactory prosecution of the work. No
equipment or hauling shall be permitted on the prepared
subgrade, except by special permission of the Engineer,
which will be granted only in exceptional cases and only
where suitable protection in the form of two-ply timber
mats or other approved material is provided.
(17) Placing and Removing Forms
The subgrade under the forms shall be firm and cut true to
grade so that each form section when placed will be firmly
in contact for its whole length and base width, and exactly
at the established grade. Forms shall be staked with at
least three pins for each 10-foot section. A pin shall be
placed at each side of every joint. Form sections shall be
tightly joined and keyed to prevent relative displacement.
Forms shall be cleaned and oiled each time they are used.
Forms shall be set for a sufficient distance in advance of
the point where concrete is being placed to permit a
finished and approved subgrade length of not less than 300
feet ahead of the mixing. Conformity of the grade and
alignment of forms shall be checked immediately prior to
placing concrete, and all necessary corrections made by the
Contractor. Where any forms have been disturbed or any
subgrade becomes unstable, the forms shall be reset and
rechecked. In exceptional cases, the Engineer may require
stakes driven to the grade of the bottom of the forms.
Sufficient stability of the forms to support the equipment
operated thereon and to withstand its vibration without
springing or settlement shall be required. If forms settle
and/or deflect over 1/8 inch under finishing operations,
paving operations shall be stopped and the forms shall be
reset to line and grade.
Forms shall remain in place for not less than 12 hours
after the concrete has been placed. They shall be carefully
removed in such a manner that little or no damage will be
done to the edge of the pavement. Any damage resulting from
this operation shall be immediately repaired. After the
forms have been removed, the ends of all joints shall be
cleaned, and any honeycombed areas pointed up with approved
mortar. Immediately after pointing is completed, the form
trench, if used, shall be filled with earth from the
shoulders in such a manner as to shed water from rainfall
or curing away from the edge of the pavement. On completion
of the required curing, the subgrade or shoulders adjacent
to the pavement shall be graded in a condition to maintain
`� drainage.
Allowable grade revisions shall in no way affect the
governing finishing and surface requirements of the
completed pavement.
All grade revisions shall be established by the Engineer.
No additional payment over the contract unit price will be
made for any pavement of a thickness exceeding that
required on the plans as.a result of adjustment.of the
forms.
I. Concrete Mixing and Placing
�. (1) Mixing
The aggregates, mineral filler if required, cement.and
water shall be measured separately, introduced into the
mixer, and mixed for a period of not less than 50 seconds
nor more than 90 seconds, measured from the time the last
aggregate enters the drum to the time discharge of the
concrete begins. The required water shall be introduced
into the mixing drum during the first 15 seconds of
mixing. The entire contents of the drum shall be discharged
before any materials of the succeeding batch are
introduced.
The Engineer may increase the minimum mixing time to that
necessary to produce thoroughly mixed concrete based on
inspection or appropriate uniformity tests. The mixing time
may be varied at any time necessary to produce acceptable
.., concrete.
If Ready -Mix concrete is used, the concrete shall be
discharged into the specified hauling equipment and
"^. delivered to the road site. If truck agitators are used,
the concrete shall be continuously agitated at not less
than one nor more than six rpm as directed by the Engineer.
The initial batch of concrete mixed after each time the
mixer is washed out shall be enriched by additional mortar.
The additional mortar shall be one sack of cement and three
parts of sand.
(2) Placing
Any concrete not placed as herein prescribed within 30
minutes after mixing shall be rejected and disposed of as
-� directed except as provided otherwise herein. Except by
specific written authorization of the Engineer, concrete
shall not be placed when the temperature is below 40F, the
temperature being taken in the shade and away from
r artificial heat.
When such permission is granted, the Contractor shall
furnish an approved enclosure, such as canvas -covered
framework, to enclose and protect all pavement so placed,
and shall maintain the temperature of the air surrounding
the concrete at not less than 50 F for not less than 5
days. When concrete is being placed in cold weather, other
than under the conditions stated above, the Contractor
shall have available a sufficient supply of an approved
covering material to immediately protect concrete if the
air temperature falls to 32 F, or below, before concrete
has been placed 4 hours. Such protection shall remain in
place during the period the temperature continues below 32.
F or for a period of not more than 5 days. Neither salt nor
other chemical admixtures shall be added to the concrete to
prevent freezing. The Contractor shall be responsible for
the quality and strength of concrete under cold weather
conditions and any concrete damage by freezing shall be
removed and replaced at his expense. .Concrete shall not be
placed before sunrise and shall not be placed later than
will permit the finishing of the pavement during sufficient
natural light.
Concrete shall be placed only on approved subgrade or sub
base, and unless otherwise indicated on plans, the full
width of the pavement shall be constructed monolithically.
The concrete shall be deposited on the subgrade or sub -base
in such manner as to require as little rehandling as
possible. Where hand spreading is necessary, concrete shall
be distributed to the required depth by use of. shovels. The
use of rakes will not be permitted. Workmen will not be
permitted to walk in the concrete with any earth or foreign
material on their boots or shoes. The placing of.concrete
shall be rapid and continuous.
Concrete shall be distributed to such depth that when
consolidated and finished, the slab thickness required by
plans will be obtained at all points and the surface shall
not, at any point, be below the established grade. Special
care shall be exercised in placing and spading concrete
against forms and at all joints to prevent the forming of
honeycombs and voids.
If in the opinion of the Engineer, the temperature, wind
and/or humidity conditions are such that the quality of the
concrete will not be adversely affected, the specified
placing time may be extended to a maximum of 45 minutes.
(3) Reinforcing Steel
All reinforcing steel, including steel wire fabric
reinforcement, tie bars, and dowel bars shall be accurately,
placed and secured in position in accordance with details
shown on plans. Reinforcing bars shall be securely wired
together at alternate intersections, following a pattern
approved by the Engineer,.and at all splices, and shall be
securely wired to each dowel intersected. When wire fabric
is used, it shall be securely wired together at all splices
and to each dowel intersected. Tie bars shall be installed
in the required position by the method and device shown on
plans or by approved method and device equivalent thereto.
Tightly adhered scale or rust which resists removal by
vigorous wire brushing need not be removed except that
excessive loss of section to the reinforcement due to rust
shall be cause for rejection. Excessive loss of section
shall be defined as loss of section to the extent that tl:e
•-� reinforcement will no longer meet the physical requirements
for the size and grade of steel specified.
Where plans require an assembly of parts at pavement
joints, the assembly shall be completed, placed at required
location and elevation, and all parts rigidly secured in
required position by the method and devices shown on plans.
Dowel bars shall be accurately installed in joint
assemblies in accordance with plans, each parallel to the
pavement surface and to the center line of the pavement,
and shall be rigidly secured in required position by such
means (as shown on plans) that will prevent their
displacement during placing and finishing of the concrete.
(4) Joints
When the placing of concrete is stopped, a bulkhead of
-- sufficient cross sectional area to prevent deflection,
accurately notched to receive the load transmission devices
or dowels if required, and shaped accurately to the cross
section of the pavement shall be provided and installed as
a back-up for the joint filler and rigidly secured in
required position to permit accurate finishing of the
concrete up to the joint. After concrete has been finished
to the joint, formation of the joint seal space and
finishing of the joint shall be executed. The back-up
bulkhead shall remain in place until immediately prior to
the time when concrete placing is resumed, when it shall be
carefully removed in such manner that no element of the
--
V-22
joint assembly will be disturbed. The exposed portion of
the joint assembly shall be free of adherent concrete, dirt
or other material at the time placing of concrete is
resumed.
If necessary for proper installation of joint sealer,
excessive spalling of the joint groove shall be repaired to
the satisfaction of the Engineer in the manner which he
prescribes.
Careful workmanship shall be exercised in the construction
of all joints to insure that the concrete sections are
completely separated by an open joint or by the joint
materials and to insure that the joints will be true to the
outline indicated.
(5) Weakened Plane Joints
Weakened plane joints shall consist of transverse
contraction joints and longitudinal joints and shall be
sawed as specified on the plans or as directed by the
Engineer. When the joints are sawed, the saw shall be power
driven, shall be manufactured especially for the purpose of
sawing concrete, and shall be capable of performing the
work. Saw blades shall be designed to make a clean smooth
cut having a width and depth of cut as detailed on the
plans. Tracks adequately anchored, chalk, string line or
other approved methods shall be used to provide true
alignment of the joints. The concrete saw shall be
maintained in good operating condition and the Contractor
shall keep a stand-by power saw on the project at all times
when concrete operations are under way.
If membrane curing is used, the portion of the seal which
has been disturbed by sawing operations shall be restored
by the Contractor by spraying the area with additional
curing seal.
(6) Contraction Joints
Transverse contraction joints shall be formed or sawed
joints perpendicular to the centerline and surface of the
pavement. Where sawed joints are used, contraction joints
at approximately 10 to 15-foot intervals shall.be sawed as
soon as sawing can be accomplished without damage to the
pavement and before 12 hours after the concrete has been
placed, the exact time to be approved by the Engineer. The
remaining contraction joints shall be sawed in a unifor:a
ate —
pattern as directed by the Engineer, and they shall be
completed before uncontrolled cracking of the pavement
takes place. All joints shall be completed before
permitting traffic to use the pavement..
(7) Longitudinal Joints
Longitudinal joints shall be sawed within two days after
construction of the pavement. Sawing shall not cause damage
to the pavement and the grooves shall be cut with a minimum
of spalling. No traffic (including construction traffic)
shall be permitted on the pavement until the longitudinal
.- joint is cut..
(8) Joint Sealers
After the joints in the hardened concrete have been
repaired (if necessary) and cleaned to the satisfaction of
the Engineer, the joints will be filled with the W.R.
Meadows sof-seal. After the sealant is installed.it.will
effectively seal the joints against water, dirt and stones
throughout repeated cycles of expansion and contraction..
(9) Asnhalt Board
Premolded materials, wherever used, shall be anchored to
the concrete on one side of the joint by means of copper
wire or nails not lighter than No. 12 B&S gage. Such
anchorage shall be sufficient to overcome the tendency.of
the material to fall out of the joint.
(10) Spreading and Finishing
All concrete pavement shall be consolidated by a mechanical
vibrator. As soon as the concrete has been spread between
the forms, the approved mechanical vibrator shall be
operated to consolidate the concrete and remove all voids.
Hand manipulated vibrators shall be used for areas not
covered by the mechanical vibratory unit.
After finishing is completed and the concrete still
workable, the surface shall be tested for trueness with an
approved 10-foot steel straightedge. The straightedge shall
be operated from the side of the pavement, placed parallel
to the pavement centering and passed across the slab to
reveal any high spots or depressions. The straightedge
shall be advanced along the pavement in successive stages
of not more than one-half its length. Practically perfect
contact of the straightedge with the surface will be
required, and the pavement shall be leveled to this
�- condition, in order to insure conformity with the surface
test required after the pavement has fully hardened. Any
correction of the surface required shall be accomplished by
adding concrete if required and by operating the
longitudinal float over the area. The surface test with the
straightedge shall then be repeated. Extra water will not
be added for finishing.
After completion of the straightedge operation, the first
pass of the burlap drag shall be made as soon as
construction operations permit and before the water sheen
has disappeared from the surface. This shall be followed by
as many passes as required to produce the desired texture
depth. There shall be no unnecessary delays between passes.
The drag shall be wet during use and maintained clean and
free from encrusted mortar. It is the intent that the
average texture depth resulting from the number of tests
directed by the Engineer be not less than 0.025 inches with
a minimum texture depth of 0.020 inches for any one test.
Should the texture depth fall below that intended, the
finishing procedures shall be revised to produce the
desired texture.
The Contractor shall have available at all times hand
brooms with stiff bristles for the purpose of providing
textures when the pavement surface is in such a condition
that the burlap drag or other methods being employed will
not provide the desired texture.
After completion of dragging and about the time the
concrete becomes hard; the edge of the slab and -joints
shall be carefully finished as directed by the Engineer,
and the pavement shall be left smooth and true to line..
(11) Protection of Pavement and Opening to Traffic
The Contractor shall erect and maintain the barricades
required by plans and such other standard and approved
devices as will exclude public traffic and traffic of his
employees and agents from the newly placed pavement for the
periods of time and at locations hereinafter prescribed by
the Engineer. Portions of the roadway, or crossings of the
roadbed required to be maintained open for use by traffic,
shall not be obstructed by the above required barricades.
The pavement shall be closed to all traffic, including
vehicles of the Contractor, until the concrete is at least
7 days old. This period of closure to all traffic may be
extended if, in the opinion of the Engineer, weather or
other conditions make it advisable to provide an extension
- -of the time of protection.
At the end of the 7 day period and as long thereafter as
ordered by the Engineer, and if so desired by the
Contractor, the pavement may be opened for use by vehicles
of the Contractor provided the gross weight (vehicle plus
load) of such vehicles does not exceed 14,000 pounds. Such
opening, however shall in no manner relieve the Contractor
from his responsibilities for the work. On those sections
of the pavement thus opened to traffic, all joints shall
first be sealed, the pavement cleaned and earth placed
against the pavement edges before permitting vehicles
thereon.
After the concrete in any section is 14 days old, or as
long thereafter as ordered by the Engineer, such section of
pavement may be opened to all traffic as required by plans
or when so directed by the Engineer. On those sections of
the pavement thus opened to traffic, all joints shall first
be sealed, the pavement cleaned, earth placed against the
pavement edges and all other work performed as required for
,.. the safety of traffic.
When High Early Strength Concrete, resulting from the use
of Type III cement as required by plans or special
provisions, is used, the pavement may be opened to all
traffic after the concrete is 7 days old, or as long
thereafter as ordered by the Engineer, subject to the same
°^ provisions governing the opening after 14 days as above
prescribed.
,. Where the Contractor desires to move any equipment not
licensed for operating on public streets, on or across any
pavement opened to traffic, he shall protect the pavement
from all damage by means of two-ply timber mats of 2 inch
stock or runways of heavier material laid on a layer of
earth, all as approved by the Engineer.
The Engineer may require the opening of pavement to traffic
prior to the minimum time specified above under conditions
of emergency which in his opinion require such action in
the interest of the public. In no case shall the Engineer
order opening of the pavement to traffic within less than
72 hours after the last concrete in the section is placed.
The Contractor shall remove all obstructing materials,
place earth against the pavement edges and perform other
work involved in providing for the safety of traffic as
required by the Engineer in ordering emergency opening.
Orders for emergency opening of the pavement to traffic
will be issued by the Engineer in writing.
2. Earth Work
A. Subarade Preparation for curb and clutter, streets,
paving (asphalt and concrete) allev returns alley pavir.a,
valley gutters, and earth work.
Description -
Sub -grade preparation shall include the removal, haul and
disposal of all obstructions, including existing curbs,
gutters, paving materials, base materials, concrete slabs
and other obstructions shown on the plans or as designated
by the Engineer and all scarifying, pulverizing, wetting,
disking, blading and rolling with compactors to a depth of
at least 6" on residential streets and to a depth of 12" on
major thoroughfares and collector streets. Compactors will
be used from the bottom to the finished sub -grade elevation
to compact the subgrade to 95% Standard Proctor Density
(A.S.T.M. D-698) in conformity to the line, grade and
sections as shown on the plans or as established by the
Engineer.
After the obstructions have been removed, or in conjunction
with such removal, the street bed and/or alley return
foundation and/or sidewalk foundation shall be excavated
and shaped in conformity with the typical section and to
the line and grades as shown on the plans or as established
by the Engineer.
All unstable or otherwise objectionable material shall be
removed from the subgrade and replaced with approved
material. The excavation shall be done in such a manner as
to require a minimum of fill to bring the subgrade to the
correct elevation. When the subgrade is too low as
initially excavated, the Contractor shall place additional
soil or caliche in layers not exceeding four (411) inches
and compact each layer by moistening and rolling.
(1) Scraper Work
The utilization of a scraper for excavation and shaping of
subgrade and base is permitted with exceptions which are
determined by depths of utility lines. Unless otherwise
specified by the Engineer, the scraper shall not exceed 2i
cubic yards capacity as rated loaded flush by'the
manufacturer.
(2) Compaction
The subgrade will be wetted and rolled to secure 95%
-y ----- Standard Proctor Density. Before placement of the base
and/or curb and gutter and/or concrete valley gutter anal/or
alley return slab and/or sidewalk, the subgrade will be
checked by test rolling six (6) times or more if required
by the Engineer with a self-propelled roller weighing not
less than 35 tons. Any soft of unstable spots found by teat
rolling will be corrected by removing the soft or unstable
material and replacing it with suitable soil compacted to
95% Proctor Density. The areas so corrected shall be test
rolled as specified above.
(3) Intersection
Special care shall be exercised in grading street
intersections where dips are located so that the cross
profiles present a smooth riding surface and so that the
compacted base thickness will not be less than six (611) or
nine (911). Crown section shall begin to decrease 60 feet
back of end of radius for residential streets. Wider street
dips will be blue topped as shown on the detail sheet.
(4) Prosecution of the Work
The Contractor may proceed with subgrade preparation on any
schedule he may select except that, unless hindered by
factors beyond his control, not more than seven (7)
calendar days shall elapse between the time subgrade
preparation is begun and the spreading and compacting of
r- the caliche base has started. Measures shall be taken by
the contractor not to leave driveways impassable during the
night hours.
(5) Excess Materials
Materials excavated in excess of that needed in fill and
'^ backfill behind curb shall be wasted by the Contractor.
Care shall be taken by the Contractor to use only topsoil
in the backfill behind the curbs. The Contractor may
dispose of the surplus excavated material in any manner not
objectionable to the public, and it is his responsibility
to locate a suitable site for dumping the waste excavation.
In any event, the Contractor shall not dispose of the
surplus materials in any of the lake areas either outside
or within the city limits. Location of disposal sites near
any lake area must be approved by the Engineer.
(6) Subarade for Alley Paving
The preparation of the subgrade for concrete alley paving
shall be done in the same manner as other subgrade
excavation which requires scarifying, wetting, disking,
blading, rolling, and compacting. The Contractor will be
required to excavate around existing improvements such as
gas meter, water meters, poles, etc. Each of these
obstructions shall be the responsibility of the Contractor.
Trees that conflict with the improvements shall be removed
by the Contractor upon approval of the Engineer.
The Contractor shall shape the subgrade to the cross-section
shown on the plans and to the lines and grades established
by the Engineer. After the forms are set and before the
reinforcing is placed, the Contractor shall finally shape
the subgrade so that there will be a minimum thickness of
concrete of five inches (51') at the centerline and seven
and one-half inches (7-1/211) at the outside edges. All
areas where fill material is required shall be compacted.
The subgrade shall be wetted and rolled to secure 900
Proctor Density in the upper six inches (6") making a firm
foundation for the alley paving.
The Contractor will be required to shape the portion of the
alley outside of the limits of the concrete slab so that
all drainage in the alley will be to the invert of the
concrete slab. Excess excavated materials shall be hauled
to any approved location.
B. Embankment
Description
Prior to placing any embankment, all "Preparing Right -Of -
Way" and/or "Clearing and Grubbing" operations shall have
been completed on the excavation sources and areas over
which the embankment is to be placed. Stump holes or other
small excavations in the limits of the embankment shall be
backfilled with suitable material and thoroughly tamped by
approved methods before commencing embankment construction.
The surface of the ground, including plowed loosened
ground, or surface roughened by small washes or otherwise,
shall be restored to approximately its original slope by
blading or other methods and where indicated on plans or
required by the Engineer, the ground surface thus prepared
shall be compacted by sprinkling and rolling.
Where embankments are to be placed adjacent to or over
existing roadbeds, the roadbeds slopes shall be plowed or
scarified to a depth of not less than six (611)' inches and
the embankment built up in successive layers, as
hereinafter specified, to the level of the old roadbed
before its height is increased. Then, if directed, the top
of the roadbed shall be scarified and recompacted with the
V-29
next layer of the new embankment. The total depth of the
scarified and added material shall not exceed the
permissible depth of layer.
Trees, stumps, roots, vegetation, or other unsuitable
materials shall not be placed in embankment.
Except as otherwise required by the plans, all embankment
shall be constructed in layers approximately parallel to
the finished grade of the roadbed and unless otherwise
specified each layer shall be so constructed as to provide
a uniform slope of 1/411 inch per foot from the center line
of the roadbed to the outside.
Embankments shall be constructed to the grade established
by the Engineer and completed embankments shall correspond
to the general shape of the typical sections shown on -the
-- plans and each section of the embankment shall correspond
to the detailed section or slopes established by the
Engineer. After completion of the roadway, it shall be
continuously maintained to its finished section and grade
until the project is accepted.
Except as otherwise specified, earth embankments shall be
constructed in successive layers for the full width of the
individual roadway cross section and in such lengths as are
best suited to the sprinkling and compaction methods
�. utilized.
Layers of embankment may be formed by utilizing equipment
which will spread the material as it is dumped, or they may
r" be formed by being spread by blading or other acceptable
methods from piles or windrows dumped from excavating or
hauling equipment in such amounts that material is evenly
,- distributed.
Minor quantities of rock encountered in constructing earth
embankment shall be incorporated in the specified
embankment layers, or may be placed in accordance with the
requirements for the construction of rock embankments in
the deeper fills within the limits of haul shown on the
plans, provided such placement of rock is not immediately
adjacent to structures. Also, rock may be placed in the
portions of embankments outside the limits of the completed
^, roadbed width where the size of the rock prohibits their
incorporation in the normal embankment layers.
Each layer of embankment shall be uniform as to material,
density and moisture content before beginning compaction.
where layers of unlike material-
��•�- --
material shall be so mixed as to prevent abrupt changes in
the soil. No material placed in the embankment by dumping
in a pile or windrow shall be incorporated in a layer in
that position, but all such piles or windrows shall be
moved by blading or similar methods. Clods or lumps of
material shall be broken and the embankment material mixed
by blading, disking, or similar methods to the end that a
uniform material or uniform density is secured in each
layer. Water required for sprinkling to bring the material
to the moisture content necessary for maximum compaction
shall be evenly applied and it shall be the responsibility
of the Contractor to secure a uniform moisture content
throughout the layer by such methods as may be necessary.
In order to facilitate uniform wetting of the embankment
material, the Contractor shall water at the material source
if the sequence and methods used are such as not to cause
an undue waste of water. Such procedure shall be subject to
the approval of the Engineer.
(1) Comoaction
The compaction method shall require that each layer shall
be compacted to the required density by any method, type,
and size of equipment which will give the required
compaction. The depth of layers, prior to compaction, shall
depend upon the type of sprinkling and compaction equipment
used. Prior to and in conjunction with the rolling
operation, each layer shall be brought to the moisture
content necessary to obtain the required density and shall
be kept leveled with suitable equipment to insure uniform
compaction over the entire layer.
For each layer of earth embankment and select material, it
is the intent of this specification to provide the density
as required herein, unless otherwise shown on the plans.
The required compaction shall be 95% Standard Proctor
Density A.S.T.M. D-698.
After each section of earth embankment or select material
is complete, tests as necessary will be made by the
Engineer. If the material fails to meet the density
specified, the course shall be reworked as necessary to
obtain the specified compaction, and the compaction method
may be altered on subsequent work to obtain specified
density. Such procedure shall be determined by, and subject
to, the approval of the Engineer.
At any time, the Engineer may order proof rolling to test
the uniformity of compaction of the embankment subgrade.
All irregularities, depressions., weak or soft spots which
develop shall be corrected immediately by the Contractor.
I
Should the subgrade, due to any reason or cause, lose
required stability, density, or finish before the pavement
°^ structure is placed, it shall be recompacted and refinished
at the sole expense of the Contractor. Excessive loss of
moisture in the subgrade shall be prevented by sprinkling,
,., sealing, or covering with a subsequent layer of granular
material. Excessive loss of moisture shall be construed to
exist when the subgrade soil moisture content is more than
4 percent below the optimum for compaction to Standard
Proctor Density. (Also see Section V, Item 2 [A]
Compaction.)
.� At Culverts
Embankments adjacent to culverts which cannot be compacted
by use of the blading and rolling equipment used in
compacting the adjoining sections of embankment shall be
compacted in the manner prescribed below.
The following requirements shall apply to the backfilling
of pipe culverts in addition to the pertinent portions of
the general requirements given in the preceding section.
After the bedding has been prepared and the pipe installed
as required by the pertinent specifications, selected
materials from excavation or borrow shall be placed along
both sides of the pipe equally, in uniform layers not to
exceed six inches (6t') in depth (loose measurement), wetted
and thoroughly compacted so that on each side of the pipe
there shall be a berm of thoroughly compacted materials at
least as wide as the external diameter of the pipe, except
insofar as undisturbed material obtrudes into this area.
The method and degree of compaction shall be same as
specified above.
Filling and/or backfilling shall be continued in this
manner to the elevation of the top of the pipe. Special
care shall be taken to secure thorough compaction of the
material placed under the haunches of the pipe. All fill or
backfill below the top of the pipe shall be compacted
mechanically in the same manner and to the density
prescribed above, regardless of whether or not such
material is placed within the limits of the embankment or'
roadbed.In the case of embankments, the remainder of the
fill above the top of pipe shall be placed in accordance
with the provisions for placing roadway embankment as
..- prescribed in the pertinent specification included in the
contrast. No construction traffic will be permitted to
cross any pipe culvert until the specified minimum depth of
fill above the pipe has been placed and consolidated in
accordance with these provisions.
3. Base Course
The base course shall consist of a minimum of six (611) or nine
(911) inches of .compacted approved caliche, black base or
combination of caliche and black base material shaped in
accordance with the typical cross -sections provided in the
plans and to the grades established by the Engineer.
A. Haulinct and Placing
Approved base material shall be hauled in vehicles of
uniform capacity to the site and dumped evenly so that an
adequate quantity of material will be placed to provide a
minimum of six (611) inches of compacted base material on
all units except major thoroughfares streets. On these
streets the Contractor will construct nine (911) inches of
compacted base material.
B. Processing
Processing of caliche base shall be accomplished in
mulitiple lifts of three (311) inches in compacted depth.
Each lift or layer shall be thoroughly moistened and rolled
as it is cut from the windrow. After all of the material is
cut from the windrow to the sides, it shall be cut back to
the center in lifts of three (311) inches and thoroughly
moistened and rolled again. Succeeding layers shall then be
placed similarly until the caliche base course is completed
and 95% Proctor Density has been attained.
All nine (911) inch compacted caliche base shall be
accomplished in three (311) inch lifts. The caliche course
shall then be sprinkled as required and rolled with
compactors as directed until a uniform compaction of 95% of
"Standard Proctor Density" is secured. Throughout this
entire operation, the shape of the course shall be
maintained by blading; and the surface upon completion
shall be smooth and in conformity with the typical sections
shown on plans and to the established lines and grade.
Processing of asphaltic base shall be as directed by the
Engineer and similar to that described under Hot Mix
Asphaltic Concrete Surface. Lift thickness will be
indicated by the Engineer or as shown on the paving plans: -
Electronic screed controls will be required for placing
black base on grade. The density required will be
determined by the Engineer after material to be used has
been approved. All areas and "nests" of segregated coarse
or fine material shall be corrected or removed and replaced
with well graded material as directed by the Engineer. Each
..,._—_. ----.layer of black base will be test rolled six (6) times with
a 35 ton roller and approved by the Engineer before
succeeding layers are placed. A delay in construction of
the next succeeding layer of black base.caused by rain,
snow, etc. will require re -rolling and approval prior to
construction of the next layer..
The utilization of the traffic to compact and bind the base
is an essential part of the construction, and whenever
possible the base course shall be opened to traffic,, and.
the Contractor shall direct and distribute the traffic
-- uniformly over the entire width of the base course. During
the period of at least seven (7) days that traffic is being
directed over the base, the caliche base shall be
satisfactorily maintained by the use of water trucks,
blades, drags and such other equipment as is required. The
base course shall be so maintained until the wearing
surface is placed thereon. The surface shall not be placed
on base course that exceeds optimum moisture by two (20)
per cent.
.-- C. Finishincr
Description
The compacted base shall be finished and shaped immediately
preceding the application of the surface treatment. All.
loose or unconsolidated material shall be removed and the
surface moistened and rolled with a steel wheel roller. All
irregularities, depression or weak spots which develop
during compaction shall be corrected by scarifying the
areas affected, adding or removing material as required,
reshaping and recompacting by sprinkling and rolling.
(1) Weak Spots in Base
The finished base shall be checked by a minimum of six (6)
test rollings with a 35 ton roller. Any weak spots found
shall be remedied before the surface is applied. The weak
spots may be remedied by reprocessing the area in which the
weak spot is found in which case the base will be allowed
to cure for 72 hours before the surface is applied. If the
Contractor chooses, he may repair the weak spot by removing
the material involved and replacing it with type "C" hot
mix or asphalt stabilized base. In this case the surface
may be applied as soon as the hot mix patch has been
compacted and cooled to ambient temperature.
(2) Allowable Deviation in Finish
Immediately prior to olacinct of surfacing the base shall
be checked and anv deviation in excess of three -eights
(3/8) inch from the established grade or true cross section
shall be corrected as provided for defects.
Longitudinally a straightedge 10 feet long shall be used
to detect any deviation which shall be corrected as defects.
4. HOT MIX ASPHALTIC CONCRETE SURFACE
A. Description
This item shall consist of 1-2" compacted T.H:D. Type "D"
hot mix asphaltic concrete surface,. using approved
crushed stone aggregate, constructed over a compacted
base. The base shall be primed and a tack coat applied
as required.
(1) General (Test Method Tex-207-F)
It is the intent of this specification that the material
be placed and compacted to a density of 95 to 100 percent
of that density developed in the laboratory test method
of molding stability specimens with a m;nimum compacted
thickness of one and ore -half inches (1-2"). Suff.ic.ient
density tests will be made in order t.o determine that the
compaction procedure used by the Contractor is adequate
and proper to accomplish the intent:�as stated above.
If the mixture produced does not have the specified
qualities, the design will be adjusted as required by
the engineer to produce a mixture having the specified
qualities. The pavement shall be constructed on the
previously completed -and approved subgrade, base,existing
pavement, bituminous surface or in the case of a bridge,
on the prepared floor slab, as herein specifiec and in
accordance with the details shown on the plans.
Temperature Requirements
A. November 1 until April 1
1. The asphaltic mixture shall not be placed when the air
temparature is below 55 degrees F and falling.
2. The asphaltic mixture may be placed when the air tem-
perature is above 50 degrees F and rising.
B. April 1 until November 1
1. The asphaltic mixture shall not be placed when the air
temperature is below 50 degrees F and falling.
The asphaltic mixture may be placed when the air tem-
per1:ure is above 45 degrees F and rising.
r.,
The air temperature shall be taken in the shade away from
artificial heat or as reported by the National Weather
service on their hourly report (Telephone No. 762-0141)..
The Engineer may use his discretion to require a cover over
the asphaltic mixture when being hauled from the plant to
the job site.
If the temperature of a load of asphaltic concrete measured
while passing through the lay -down machine is 25 degrees F
less than the mixing temperature, the load may be rejected
by the Engineer and payment will not be made for the
rejected material.
(2) Prenaration of Base and Areas Bordering
The compacted base upon which the hot mix asphaltic
concrete surface is to be placed shall be prepared and
cleaned, as required by the Engineer, before the prime coat
is applied.
(3) Prime Coat
The prime coat shall consist of an application of .25
gallons per square yard of MC asphalt.
(4) Tack Coat
Before the asphaltic mixture is laid, the surface upon
which the tack coat is to be placed shall be cleaned
thoroughly to the satisfaction of the engineer. The surface
shall be given a uniform application of tack coat using
asphaltic materials of this specification. This tack coat
shall be applied, as directed by the engineer, with
approved sprayer. Where the mixture will adhere to the
surface on which it is to be placed without the use of a
tack coat, the tack coat may be eliminated by the Engineer..
All contact surfaces of curbs and structures and all joints
shall be painted with a thin uniform coat of the asphaltic
material meeting the requirements for tack coat. The tack
coat shall be rolled with a pneumatic tire roller as
directed by the Engineer.
(5) Transnortinq Asphaltic Concrete
The asphaltic mixture, prepared as specified above shall be
hauled to the work site in tight vehicles previously
cleaned of all foreign material. The dispatching of the
vehicles shall be arranged so that all material delivered
may be placed, and all rolling shall be completed during
day -light hours. The inside of the truck body may be
V-36
