eral Conditions.

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

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 schedute 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 my direct the Contractor to take such action as the City deems necessary to insure comple-
tion of the project within the time specified.

pending, of which the Contractor has been ratified.
T. KATERIALS 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

sion. The specifications for materials and methods set forth in the contract documents provide minimum

fective materials and workmanship. Prior to final acceptance, the Contractor shall furnish to the Owner, a

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.

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-

at Contractor's expense.

cades, signs, and lights shall not cease until the date of issuance to Contractor of City's certificate of
acceptance of the project.

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 smatters which in any way effect
the work under this contract. No verbal agreement or conversation with any officer, agent, or employee of
the Comer, either before or after the execution of this contract, shall effect or Modify any of the terms or
obligations herein contained.

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.

.28-
21. OBSERVATION AND TESTING
The Owner or Owner►s Representative shalt 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-
1 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 -
pie 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 piece 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 mist, if requested by Owner or Owner's Repro -
tentative. 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
r• 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 taw 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
r
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 to 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 my 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 eontm?tated, 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 York. In
r" -29-
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 toss occasioned by such change, due to actual expenses incurred in
preparation for the work as originally planned.
24. € TRA 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-
*red 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.

i 49. ABANDONMENT BY CONTRACTOR
In ease the Contractor should abandon and fail or refuse to resume work within ten (10) days after written
notification from the Owner or the Owner's 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 York, 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.
r' In case the Surety should fail to commence compliance with the notice for completion hereinbefore provided
ffor 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 cam -
plated by the Contractor, then said Contractor shall receive the difference. In case such expense
is greater than the sun which would have been payable under this contract, if the same had been can-
pleted by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess
7I to the Owner; or
(b) The Owner, under sealed bids, after notice published as required by taw, 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
rcompletion 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
r'1 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.

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 fait 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

(5) Mixing
(a) Weigh -Batch Tvice Mixer
In the charging of the weigh box and in the
charging of the mixer from the weigh box such
methods or devices shall be used as are necessary
to secure a uniform asphalt mixture. In
introducing the batch into the mixer, all mineral
aggregate shall be introduced first and shall be
mixed thoroughly for a period of 5 to 20 seconds,
or as directed, to uniformly distribute the various
sizes throughout the batch before the asphaltic
material is added. The asphaltic material shall
then be added and the mixing continued for a total
mixing period of not less than 30 seconds. This
mixing period may be increased, if in the opinion
04-7
of the Owner, the mixture is not uniform. The
differential in temperature of the aggregates and
the asphalt as.they enter the pugmixer shall not
exceed 250 F.
Temporary storing or holding of the asphaltic
mixture by the surge -storage system may be used
during the normal day's operation. Overnight
storage will not be permitted. The mixture coming

quality to that coming out of the mixer.
(b) Continuous -Type Mixer
The amount of aggregate and asphaltic material
entering the mixer and the rate of travel through
the mixer shall be so coordinated that a uniform
mixture of the specified grading and asphalt,
content will be produced. The differential In
temperature of the aggregates and the asphalt as _
they enter the pugmixer shall not exceed 250 F.
Checks on asphalt used shall be made at -least twice
daily comparing the asphalt used in ten loads of
completed mix as shown on the asphalt recording
meter and the design amount for these ten loads.
The acceptable percent of variation between the
asphalt used and the design amount will be as shown
on the plans or as determined by the Owner.
D. Construction Methods
(1) Temperature Requirements
A. HMAC - November 1 until April 1
1. The asphaltic mixture shall not be placed when the
air temperature is below 550 F and falling.
2. The asphaltic mixture may be placed when the air
temperature is above 500 F and rising.
B. MAC - April I until November 1
1. The asphaltic mixture shall not be placed when the
air temperature is below 500 F and falling.
2. The asphaltic mixture may be placed when the air
temperature is above 45° F and rising.
C. Asphalt Stabilized Base
1. The asphaltic mixture shall not be placed when the
air temperature is below 450 F and falling.
04-8
r
2. The asphaltic mixture may be placed when the air
temperature is above 400 F and rising.
The Owner may use his discretion to require a cover over the
asphaltic mixture when being hauled from the plant to the job
site. 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). It is further
provided that the prime coat, tack coat or asphalt stabilized
base shall be placed only when the general weather conditions
and temperature and moisture conditions of the subbase or
subgrade,in the opinion of the Owner, are suitable.
If, after being discharged from the mixer and prior to placing,
the temperature of the asphaltic mixture is 251 F or more below
the temperature approved by the Owner, all or any part of the
load may be rejected and payment will not be made for the
rejected material.
,.., (2) prime Coat
The prime coat shall consist of an application of 0.25 gallons
per square yard of MC asphalt. The asphalt stabilized base
shall not be applied on a previously primed course until the
prime coat has completely cured.
r- (3) Tack Coat
Before the asphaltic mixture is laid, the surface upon which the
tack coat is to be placed shall be cleaned thoroughly. The
surface shall be given a uniform application of tack coat using
asphaltic materials of this specification. This tack coat shall
be applied with an approved sprayer at a rate not to exceed 0.10
gallon per square yard of surface. 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 Owner. 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 when directed by the Owner.
(4) Transporting
The asphaltic mixture, prepared as specified above shall be
hauled to the work 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 daylight hours. The inside of
the truck body may be given a light coat of oil, lime slurry if
necessary, to prevent mixture from adhering to the body. In cool
weather or for long hauls, canvas covers and insulating of truck
bodies may be required. Vehicles of the semi -trailer type are
prohibited.
.• 04-9
(5) Placing
Generally, the asphaltic mixture shall be dumped and spread on
the approved prepared surface with the specified spreading and
finishing machine, in such a manner that when properly
compacted, the finished course will be smooth, of uniform
density, and will conform with the typical sections shown on the
plans. During the application of asphaltic material, care shall
be taken to prevent splattering of adjacent pavement, curb and
gutter and structures.
The mixture shall be spread and compacted in layers or lifts.
The sequence of compacting shall be such that undue displacement
of the edge of the course does not occur. On deep lifts, the
edge of the course may be rolled with a motor grader wheel or
similar equipment or supported by blading a roll of earth
against the edge of the course prior to compacting the surface.
When the asphaltic mixture is placed in a narrow strip along the
edge of an existing pavement, or used to level up small areas of
an existing pavement or placed in small irregular areas where
the use of a finishing machine is not practical, the finishing
machine may be eliminated when authorized by the Owner, provided
a satisfactory surface can be obtained by other approved
methods.
E. Compacting
(1) The asphalt stabilized base shall be compacted thoroughly
and uniformly with the specified rollers. In lieu of the
rolling equipment specified, the Contractor may, upon
written permission from the Owner, operate other
compacting equipment that will produce equivalent relative
compaction as the specified equipment. If the substituted
compaction equipment fails to produce the desired compaction
as would be expected of the specified equipment, as
determined by the Owner, its use shall be discontinued and
the initial compaction shall be accomplished with pneumatic
tire rollers.
(2) When rolling with the three wheel, tandem, or vibratory
rollers, rolling shall start longitudinally at the
sides and proceed toward the center of the pavement,
overlapping on successive trips by at least half the
width of the rear wheel. Alternate trips of the roller
shall be slightly different in length. When rolling with
vibratory steel wheel rollers, the manufacturer's
recommendation shall be followed. Rolling shall be
continued until no further increase in density can be
obtained and all roller marks are eliminated. The motion of
the roller shall be slow enough at all times to avoid
displacement of the mixture. If any displacement occurs, it
shall be corrected at once by the use of a rake, and of
fresh mixtures where required. The roller
04-10
F
r
i
r
shall not be allowed to stand on any portion of the
pavement mixture which has not been fully compacted.
To prevent adhesion of the mixture to the roller, the
wheels shall be kept thoroughly moistened with water,
but an excess of water will not be permitted. All
rollers must be in good mechanical condition.
Necessary precautions shall be taken to prevent the
dropping of gasoline, oil, grease or other foreign
matter on the roadway, either when the rollers are.in
operation or when standing.
(3) Hand Tamping
The edges of the pavement along curbs, headers and
similar structures, and all places not accessible to
the roller, or in such positions as will not allow
thorough compaction with the rollers, shall be
thoroughly compacted with lightly oiled tamps.
F. Surface Finish
The compacted material shall conform to the typical cross
sections, lines and grades as shown on plans and directed by the
Owner and shall have a smooth surface with a reasonably uniform
texture. Unacceptable finished surfaces may be corrected by the
placement of additional mixture, all at the expense of the
Contractor.
9. ASPHALTS
Asphalts for use on this project shall comply with Texas State
Highway Department Specification, Item 300.
10. BARRICADES AND SIGNS
Barricades shall be constructed of clean, sound lumber, shall be of
first-class workmanship, and all surfaces above ground shall be
painted with an approved brand of white paint to secure thorough
coverage and a uniform white color. In no case shall less than two
coats be used. The paint for barricade stripes shall be reflective
orange and reflective white. All dimensions, striping, lighting,
painting, coloring and placement of barricades shall be in
accordance to the details and design as set forth in the Texas
Manual on UNIFORM TRAFFIC CONTROL DEVICES for Street and Highways,
Part VI, issued in May, 1983.
The Contractor shall maintain each barricade in a neat acceptable
condition and furnish replacements when necessary or requested by
the Owner.
Each sign shall be displayed only for the specific purpose
prescribed for it. Before any detour or temporary route is open to
traffic all necessary Regulatory, Warning and Guide signs shall be
in place.
Signs required by temporary conditions or restrictions shall be
removed immediately when those conditions cease to exist or the
restrictions are withdrawn. Guide signs directing traffic to and on
04-11
temporary routes or detours shall be removed when no longer
applicable.
Standardization is important with respect to design and placement,
and uniformity of application is equally important. Identical
conditions should always be marked with the same type of sign,
irrespective of where those particular conditions occur.
All signs that are to convey their message during hours of darkness
shall be reflectorized or illuminated. Signs for daytime use only
may be non-reflectorized but a fluorescent background material will
be used for increased daytime visibility if requested by the Owner.
Construction warning signs shall have a black legend on an orange
background and shall conform to the standards as to size, shape and
color as outlined in the Texas Manual on UNIFORM TRAFFIC CONTROL
DEVICES mentioned above.
Barricades, flares, and signs are a necessity in the construction
involved in this contract. The provision of these items by the
Contractor should be considered in the bid prices submitted, as no
separate compensation will be made, unless indicated otherwise in
the plans or the proposal. _
No work will be permitted on any project prior to installation of
barricades or other warning devices at the beginning and end of the
construction area. —

Avenue IQ' @ 8th Street Lubbock, Texas
1. CONCRETE
A. Curb and Gutter (Class A -Concrete
r-
Description
This item shall consist of Portland Cement concrete curb and
gutter or separate gutter as shown on the plans or as directed
by the Owner, 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 Openinos
Separate gutter sections will be placed only across alleys,
driveways, and wheelchair ramps presently in use -or where.
definitely planned for future property improvements.
2. Excavation and Subgradina
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 existing curb to remain 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.
3. Setting Forms
r' Forms for concrete and gutter shall be set to the lines and
b grades established by extending the elevation of the existing
curbs to connect smoothly after the subgrade has been prepared.
r., 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
r" plates) shall be set to hold the concrete for the curb in place
until it is to be finished.
05-1
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 Owner. 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. This operation shall be followed with a 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.
05-2
F
Concrete shall not be poured during sand storms. Concrete shall
be protected to maintain temperature of not less than 50
r' 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 light, one (1)
pound hammer shall be used. The contractor shall notplace
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. Defective forms
shall then be removed from the job site. '
7. Machine Laid Curb and Gutter
�^
Class A concrete shall be used for machine laid curb and gutter.
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 Owner. 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
r
set by the Contractor from survey marks established by the
f
Owner. Curb outline shall strictly conform to the details shown
on the plans.

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
Owner. Fill should be done prior to placement of base
materials.
10. Replacement of Damaged Curb and Gutter or Gutter
No patching of any nature shall be allowed in repairing any
damage to curb and gutter which occurs during the construction
process of paving improvements in any unit
prior to the acceptance of said unit. Where damage occurs, the
section of curb and gutter or gutter containing the damaged
portion shall be removed to the nearest joints and shall be
replaced with new construction, prior to surfacing of that
section of street.
Concrete surface finish marred by vandals, rain or sand during
setting time shall be immediately repaired with an approved
epoxy material; all abused concrete surface, along with
structural damage and defective flow line found at time of
surfacing shall be handled as described in sentence 2 above.

05-8
by the plans or. Deformed wire may be used for tie bars and
load transfer bars that require bending. When fabricated steel
bar or rod mats are specified, the mats shall meet the
requirements of ASTM A-184.
10. 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
l placement. Vibratory members shall extend across the pavement
practically to, but shall not come in contact with the side
forms. Mechanically operated vibrators shall be operated in
such a manner as to not interfere with the transverse or
longitudinal joints.
6 Separate vibratory units shall be operated at sufficiently close
intervals to provide uniform vibration and consolidation to the
entire width of the pavement. The frequency in air of the
r internal spud type vibratory units shall be not less than 8,000
cycles per minute and not less than 5,000 cycles per minute for
tube types. The Contractor shall have a satisfactory
r, 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
E concrete, as spread, is below the elevation of the finished
surface of the pavement, except for the first lift of concrete
where the double strike off method of placement is employed,
and the vibrators shall not be operated for more than 15
seconds while the machine upon which they are installed is
standing still.
Approved hand manipulated mechanical vibrators shall be
furnished in the number required for provision of proper
consolidation of the concrete along forms, at joints 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.
11. Finishing
Machine-Fininshing. All concrete pavement shall be finished
mechanically with approved power -driven machines, except as
herein provided. Hand -finishing will be permitted on the
transition from a crowned section to a superelevated section
05-9
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
normal 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 Owner.
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.
05-10
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
p being not less than 1/4 inch nor more than 1/2 inch. If
approved by the Owner, 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
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 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.
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
05-11
b. Addition of mineral filler to fine aggregate
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 Owner, 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 Subgrade 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.
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.
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 surface. Sufficient
subgrade,shall always be prepared in advance to insure
satisfactory prosecution of the work.
16. 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
05-12
r... .M.,../...Y Grp'.. t...'—'a;u:V<1,:A.keM1!!+
point where concrete pis 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
e.
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, stakes may
require being 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
f-
concrete has been placed. They shall be carefully removed in
4
such a manner that little or no damage will be done to the edge
of the pavement. Any damage resulting from this operation shall
r.,
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
r
finishing and surface requirements of the completed pavement.
k
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 Owner 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.
05-13
r-
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.
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 Owner, concrete shall not be placed when
the temperature is below 400F, the temperature being taken in
the shade and away from 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 320F, or below, before
concrete has been placed 4 hours. Such protection shall remain
in place during the period the temperature continues below 320F
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.
05-14
G i
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 spreading concrete against forms
and at all joints to prevent the forming of honeycombs and
r- voids.
If in the opinion of the Owner, 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
r. 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
Owner, and at all splices, and shall be securely wired to each
d,
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 the 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 toyreceive the load transmission devices or
dowels if required, and shaped accurately to the cross section
05-15
7
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 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.Owner in the manner which he approves.
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. Joint Sealers
After the,joints in the hardened concrete have been repaired (if
necessary) and cleaned to the satisfaction of the Owner, 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.
6. Aspbalt 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.
_7. 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
05-16
or depressions. The straightedge shall be advanced along the
pavement in successive stages of not more than one-half its
r 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 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, and the pavement shall be left smooth and
true to line.
8. Protection of Pavement and Opening to Traffic
The Contractor shall erect and maintain the barricades required
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 Owner. 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
r, the opinion of the Owner, weather or other conditions make it
advisable to provide an extension of the time of protection.
05-17
r
At the end of the 7 day period and as long thereafter as ordered
by the Owner, 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 Owner, such section of pavement
may be opened to all traffic as required by plans or when so
directed by the Owner. 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.
2. EARTH WORK
A.
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
Owner and all scarifying, pulverizing, wetting, disking,

chemical accelerators, unless otherwise accepted
in mix designs.
3.5 Finish of Formed Surfaces:
A. The following finishing procedure shall be observed:
1. After striking -off and consolidating concrete,
smooth the surface by screeding and floating.
Do not use "Jitterbugs". Use hand methods only
where mechanical floating is not possible.
Adjust the floating to compact the surface and
produce a uniform mixture.
2. After floating, test surface for trueness with a
10" straightedge. Distribute concrete as
required to remove surface irregularities, and
refloat repaired areas to provide a continuous,
smoother finish.
3. Work edges of slabs, gutters, back top edge of
curb, and formed joints with an edging tool, and
round to 1/2" radius, unless otherwise shown.
Eliminate any tool marks on concrete surface.
06-11
4. After completions of floating and when excess
moisture or surface sheen has disappeared
complete surface finishing as follows:
B. Broom Finish: Seating Wall
1. Broom finish, by lightly drawing'a fine broom
across concrete surface. Repeat operation if
required to provide a fine line texture
acceptable to the Owner. Paint wall to match
Avenue 'Q' fountain walls.
2. On inclining slab surfaces, provide a coarse,
non -slip finish by scoring surface with a stiff -
bristled broom.
C. Exposed Aggregate Finish:
1. Apply exposed aggregate finish to slabs and other
areas as shown on the drawings. Do not begin
exposed aggregate work until sample panel has
been approved by the Owner.
2. Provide redwood dividers of size and spacing as
shown on the drawings. Dividers shall be
redwood, select heart grade, and shall be
securely staked to grade and line as established
in the field.
3. Immediately following the first floating
operations, apply special approved aggregate
(3/4' diameter Vealmoor aggregate) by
broadcasting over the floor area and tamping to
embed the aggregate. Apply the aggregate at the
required rate to match the approved sample
panel.
4. After the concrete has taken its initial set,
expose the surface aggregates using a water fog
spray and fiber -bristle brooms to remove the
surface matrix. Expose the coarse aggregate
approximately 1/8" or more to match the approved
sample panel, but no so deep as to displace the
bond of the aggregate to the matrix. The use of
surface retarders will not be permitted, unless
otherwise accepted in writing by the Owner.
5. After the concrete has taken its final set, apply
a weak acid wash to clean the exposed aggregate
surfaces. Thoroughly neutralize and flush the
acid wash from the finish surfaces. Protect all
other adjacent construction and finishes from

damage due to the acid wash; repair or replace
damaged or defaced work as directed by the
Owner.
3.6 Concrete Curing and Protection:
A. ene : Protect freshly placed concrete from
premature drying and excessive cold or hot
temperature, and maintain without drying at a
relatively constant temperature for a period of time
necessary for hydration of cement and proper
hardening.
1. Start initial curing application as soon as free
water has disappeared from concrete surface
after placing and finishing. Weather
r- permitting, keep continuously moist for not less
than 72 hours.
2. Begin final curing procedures immediately
following initial curing and before concrete has
dried. Continue final curing for at least 168
cumulative hours (not necessarily consecutive)
during which concrete has been exposed to air
temperatures above 50 degrees F. Avoid rapid
drying at end of final curing period.
B. Curing Methods: Perform curing of concrete by moist
curing or by moisture retaining cover curing or by
membrane -forming curing compound and by combinations
thereof, as herein specified.
1. Provide moisture curing by following methods:
2. Keep concrete surface continuously wet by
covering with water. Continuous water -fog
spray.
3. Covering concrete surface with specified
absorptive cover, thoroughly saturating cover
with water and keeping continuously wet. Place
absorptive cover to provide coverage of concrete
surfaces and edges, with 4" lap over adjacent
absorptive covers.
4. Provide moisture -cover curing as follows:
5. Covering concrete surfaces with moisture -
retaining cover for curing concrete, placed in
widest practicable width with sides and ends
lapped at least 3" and sealed by waterproof tape
or adhesive. Immediately repair any holes or
r 06-13
r^
P
tears during curing period using cover materials
and waterproof tape.
6. Provide curing compound for slabs as follows:
7. Apply specified curing and sealing compound to
concrete slabs as soon as final finishing
operations are complete (within 24 hours).
S. Apply uniformly in continuous operation by power -
spray or roller in accordance with
manufacturer's directions. Re=coat areas
subjected to heavy rainfall within 3 hours after
initial application. Maintain continuity of
coating and repairing damage during curing
period.
9. Do not apply membrane curing compounds. on
surfaces which are to be covered with coating
material applied directly to concrete, liquid
floor hardener, waterproofing, dampproofing,
membrane roofing, floor, painting, and other
coatings and finish materials, unless otherwise
acceptable to Owner.
C. Curing Formed Surfaces: Cure formed concrete surfaces,
including undersides of beams supported slabs and
other similar surfaces by moist curing with forms in
place for full curing period or until forms are
removed. If forms are removed, continue curing by
methods specified above, as applicable.
D. Curing Unformed Surfaces: Initially cure unformed
surfaces, such as slabs, floor topping, and other flat
surfaces by moist curing.
1. Final cure unformed surfaces, unless otherwise
specified, by methods specified above, as
applicable.
2. Final cure concrete surfaces to receive liquid
floor hardener or finish flooring by use of
moisture -retaining cover, unless otherwise
directed.
3.7 Miscellaneous Concrete Items:
A. Filling -In: Fill-in holes and openings left in
concrete structures for passage of work by other
trades, unless otherwise shown or directed, after work
of other trades is in place. Mix, place and cure
concrete as herein specified, to blend with in -place

shall be PVC Schedule 40 pipe sized as shown
on the drawings and have 4" of cover minimum.
k 3.8 Concrete Surface Repairs:
+"^ A. Patching Defective Areas: Repair and patch defective
areas with cement mortar immediately after,removal of
forms, but only when acceptable to Owner.
B. Cut out honeycomb, rock pockets, voids over 1/4" in any
dimension, and holes left by tie rods and bolts, down
'to solid concrete but, in no case to a'depth of less
than V. Make edges of cuts perpendicular to the
concrete surface. Before placing cement mortar or
proprietary patching compound, thoroughly clean,
dampen with water and brush -coat the area to be
patched with neat cement grout, or proprietary bonding
agent.
C. For exposed -to -view surfaces, blend white portland
cement and standard portland cement so that, when dry,
patching mortar will match color surrounding. Provide
test areas at inconspicuous location to verify mixture
and color match before proceeding with patching.
Compact mortar in place and strike -off slightly higher
than surrounding surface.
D. Repair of Formed Surfaces: Remove and replace concrete
having defective surfaces if defects cannot be
repaired to satisfaction of Owner. Surface defects,
as such, include color and texture irregularities,
cracks, spalls, air bubbles, honeycomb, rock pockets;
fins and other projections on surface; and stains and
other discolorations that cannot be removed by
cleaning. flush out form ties holes, fill with dry
pack mortar, or precast cement cone plugs secured in
place with bonding agent.

and other objectionable conditions.
F. Correct high areas in unformed surfaces by grinding,
after concrete has cured at least 14 days.
G. Correct low areas in unformed surfaces during, or
immediately after completions of surface finishing
operations by cutting out low areas and replacing with
fresh concrete. Finish repaired areas to blend into
adjacent concrete. Proprietary patching compounds may
be used when acceptable to Owners.
H. Repair defective areas, except random cracks and single
holes not exceeding l" diameter, by cutting out and
replacing with fresh concrete. Remove defective areas
to sound concrete with clean, square cuts and expose
reinforcing steel with at least 3/4" clearance all
around. Dampen concrete surfaces in contact with
patching concrete, and brush with a neat cement grout
coating or concrete bonding agent. Mix patching
concrete of same materials to provide concrete of the
same type or class as original concrete. Place,
compact and finish to blend with adjacent finished
concrete. Cure in the same manner as adjacent
concrete.
I. Repair isolated random cracks and single holes not over
1" in diameter by dry -pack method. Groove top of
cracks and cut-out holes to sound concrete and clean
of dust, dirt and loose particles. Dampen cleaned
concrete surfaces and brush with neat cement grout
