PURCHASING MANAGER (THIS PAGE LEFT BLANK INTENTIONALLY) GENERAL INSTRUCTIONS TO BIDDERS -4- (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: Renovation of the heating, ventilation and air conditioning at the Municipal Building. 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 120 CONE HUNDRED TWENTY) 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 P-^ acceptance of the project. 14. EXPLOSIVES 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 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. 19. PROVISIONS CONCERNING ESCALATOR CLAUSES Proposals submitted containing any conditions which provide for changes in the stated bid price due to in- creases or decreases in the cost of materials, labor or other items required for the project will be re- jected and returned to the bidder without being considered. 20.

The Owner's Representative will check the Contractor's layout of all major structures and any other layout work done by the Contractor at Contractor's request, but this check does not relieve the Contractor of the responsibility of correctly locating all work in accordance with the Plans and Specifications. 11.

He has the authority to stop the work whenever such stoppage may be necessary to insure the proper execution of the contract. In order to permit delays and disputes and to discourage litigation, it is further agreed that the Owner's Representative shall, in all cases, determine the amounts and quantities of the several kinds of work which are to be paid for under this P- contract. He shall determine all questions in relation to said work and the construction thereof, and shall, in all cases, decide every question which may arise relative to the execution of this contract on the part of said Contractor. The Owner's Representative's estimates and findings shall be conditions precedent to the right of the parties hereto to arbitration or to any action on the contract, and to any rights of the Contractor to receive any money under this contract; provided, however, that should Owner's Representative render any decision or give any direction, which in the opinion of either party hereto, is not in accordance with the meaning and intent of this contract, either party may file with said Owner's Representative within 30 days his written objection to the decision or direction so rendered, and by such action may reserve the right to submit the questions so raised to arbitration as hereinafter provided. it is the intent of this Agreement that there shall be no delay in the execution of the work, therefore, written decisions or direc- tion of the Owner's Representative as rendered shall be promptly carried out, and any claim arising there- from shall be thereafter adjusted to arbitration as hereinafter provided. The Owner's Representative shall, within a reasonable time, render and deliver to both the Owner and the 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 the Owner's Representative fail to make such decision within a reasonable time, an appeal to arbitration may be taken as if his decision had been rendered against the party appealing. 15. SUPERINTENDENCE AND INSPECTION It is agreed by the Contractor that the Owner's Representative shall be and is hereby authorized to appoint from time to time such subordinate engineers, supervisors, or inspectors as the said Owner's Representative may deem proper to inspect the materials furnished and the work done under this Agreement, and to see that said material is furnished and said work is done in accordance with the specifications therefore. The Con- tractor shall furnish all reasonable aid and assistance required by the subordinate engineers, supervisors or inspectors for the proper inspection and examination of the work. The Contractor shall regard and obey the directions and instructions of any subordinate engineers, supervisors or inspectors so appointed, when such directions and instructions are consistent with the obligations of this Agreement and accompanying plans and specifications provided, however, should the Contractor object to any orders by any subordinate engineer, supervisor or inspector, the Contractor may within six (6) days make written appeal to the Owner's Representative for his decision. -26- 16. CONTRACTOR'S DUTY AND SUPERINTENDENCE The Contractor shall give personal attention to the faithful prosecution and completion of this contract and shall keep on the work, during its progress, a competent superintendent and any necessary assistants, all 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. The work, from its commencement to completion, shall be under the exclusive charge and control of the Con- 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, skillfu4 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 emp4oyed 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. The building of structures for the housing of men or equipment will be permitted only at such places as the 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. 20. SANITATION Necessary sanitary conveniences for the use of laborers on the work site, properly secluded from public ob- 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- 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.

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- 500 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 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 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- EM r: M 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. -40- (THIS PAGE LEFT BLANK INTENTIONALLY) m CURRENT WAGE DETERMINATIONS -41- (THIS PAGE LEFT BLANK INTENTIONALLY) • �:; Resolution #2502 January 8, 1987 Agenda Item #18 DGV:da RESOLUTION WHEREAS, the City Council has heretofore established the general prevailing rate of per diem wages for each craft or type of workmen or mechanics needed to execute public works contracts for the City of Lubbock in accordance with the provisions of Vernon's Ann.Civ.St., Art. 5159a; and WHEREAS, such wage rates were established by Resolution No. 719 enacted February 12, 1981, updated by Resolution No. 1590 enacted February . 23, 1984; and WHEREAS, such rates need to be updated at the present time in order to reflect the current prevailing rate of per diem wages; NOW THEREFORE: BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF LUBBOCK: �~ THAT the general prevailing rate of per diem wages for public works .contracts shall be as set forth in the following named exhibits, which exhibits shall be attached hereto and made a part hereof for all intents and purposes: .

No discrepancies or omissions of sheets or pages of the contract documents will relieve the Contractor of his duty to provide all work required by the complete contract documents. 1.02 GENERAL: A. In general, the lines and ducts to be installed by the various trades under these specifications shall be run as indicated, as specified herein, as required by particular conditions at the site, and as required to conform to the generally accepted standards as to complete the work in a neat and satisfactorily workable manner. The following is a general outline concerning the running of various lines and is to be excepted where the drawings or conditions at the building necessitate deviating from these standards. B. Piping, conduits and raceways may be run exposed in machinery and equipment spaces, where serving as connections to motors and equipment items in finished rooms where exposed connections are required, and elsewhere as indicated on the drawings or required C. All conduits in any space where they are exposed shall run parallel with the building walls. They shall enter the concealed areas perpendicular with the walls, ceilings or floors. Fittings shall be used where necessary to comply with this requirement. D. The Contractor shall thoroughly acquaint himself with the details of the construction and finishes before submitting his bid as no allowances will be made because of the Contractor's unfamiliarity with these details. -- E. The mechanical and electrical plans do not give exact details as to elevations of lines and ducts, exact locations, etc., and do not show all the offsets, control lines, pilot lines and other installation details. The Contractor shall carefully lay out his work at the site to conform to the architectural and structural conditions, to provide proper grading of lines, to avoid all obstruction, to conform to details of installation supplied by the r manufacturers of the equipment to be installed, and thereby to provide an integrated, satisfactorily operating installation.. F. The electrical plans show diagrammatically the locations of the .�, various electrical outlets and apparatus and the method of circuiting and controlling them. Exact locations of these outlets and apparatus shall be determined by reference to the general plans and to all detail drawings, equipment drawings, roughing -in drawings, etc., by measurements at the building, and in all cases shall be subject to the approval of the Engineer. The Engineer 15000-1 reserves the right to make any reasonable change in location of any outlet or apparatus before installation (within 10 feet of location shown on drawings) or after installation if an obvious conflict exists, without additional cost to the Owner. G. The mechanical plans do not give exact locations of outlets, equipment items, etc. The exact location of each item shall be determined by reference to the general plans and to all detail drawings, equipment drawings, roughing -in drawings, etc., by measurements at the building, and in cooperation with other sections. Minor relocations necessitated by the conditions at the site or as directed by the Engineer shall be made without any additional cost accruing to the Owner. H. The Contractor shall be responsible for the proper fitting of his material and apparatus into the space. Should the particular equipment which any bidder proposes to install require other space conditions than those indicated on the drawings, he shall arrange for such space with the Engineer before submitting his bid. Should changes become necessary on account of failure to comply with this clause, the Contractor shall make such necessary changes at his (the Contractor's) own expense. I. The Contractor shall submit working scale drawings of all his apparatus and equipment which in any way varies from these specifications and plans, which shall be checked by the Engineer before the work is started, and interferences with the structural conditions shall be corrected by the Contractor before the work proceeds. J. Piping and conduits serving outlets on items of equipment shall be run in the most appropriate manner. K. Exceptions and inconsistencies in plans and specifications shall be brought to the Engineer's attention before the contract is signed. Otherwise, the Contractor shall be responsible for any and all changes and additions that may be necessary to accommodate his particular apparatus, material, or equipment. L. The Contractor shall distinctly understand that the work described herein and shown on the accompanying drawings shall result in a finished and working job, and any item required to accomplish this intent shall be included whether specifically mentioned or not. M. Each bidder shall examine the plans and specifications for the General Construction. If these documents show any item requiring work under Division 15 or 16 and that work is not indicated on the respective "M", "P" or "E" drawings, he shall notify the Engineer in sufficient time to clarify before bidding. If no notification is received, the Contractor is assumed to require no clarification, and shall install the work as indicated on the General Plans in accordance with the specifications. 1.03 DIMENSIONS: A. Before ordering any material or doing any work, the Contractor shall verify all dimensions, including elevations, and shall be responsible for the correctness of the same.

Any difference which may be found shall be submitted to the Engineer for consideration before proceeding with the work. 15000-2 1.04 INSPECTION OF SITE: A. The accompanying plans do not indicate completely the existing mechanical and electrical installations. The bidders for the work under these sections of the specifications shall inspect the existing installations and thoroughly acquaint themselves with conditions to be met and the work to be accomplished in removing and modifying the existing work, and in installing the new work in the present building and underground serving to and from that structure. Failure to comply with this shall not constitute grounds for any additional payments in connection with removing or modifying any part.of the existing installations and/or installing any new work. 1.05 ELECTRICAL WIRING: A. All electric wiring, except for temperature controls, will be done under Division 16 of these specifications. The Contractor for each section shall erect all his motors in place ready for connections. The Contractor, under Division 16, shall mount all the starters and controls, furnishing the supporting structures and any required outlet boxes. B. Every electrical current consuming device furnished as a part of this project, or furnished by the Owner and installed in this project, shall be completely wired up under Division 16. Verification of exact location, method of connection, number and size of wires required, voltage requirements, and phase requirements is the responsibility of the Contractor under Division 16. If conflicts occur between the drawings and the actual requirements, actual requirements shall govern. 1.06 MOTORS AND CONTROLS: A. All motors furnished under any of the several sections of these specifications shall be of recognized manufacture, of adequate capacity for the loads involved and wound for the current characteristics shown on the electrical drawings.
