This project is subject to the `Buy American" provisions of the surface transportation assistance act of 1982 as amended by the intermodal surface transportation efficiency act of 1991. Contractor is required to sign a pre -award compliance certification and purchaser certifications with the submittal of this proposal. The engineer's estimate for this project is $180,000.00. The successful bidder shall have thirty (30) working days to complete the work. Liquidated damages shall be $500.00 per working day. Plans, Specifications, and Contract Documents may be obtained at the office of the City Clerk of the CITY OF ROSEMEAD, 8838 E.

Specifications are going to be posted on line at the City Website. Each bid must be accompanied by a bidder's security in an amount not less than 10% of the amount of the bid, as a guarantee that the bidder will, if awarded the Contract, enter into a satisfactory agreement and provide a Performance Bond and a Payment Bond, each not less than 100% of the total amount of the bid price. No bidder may withdraw his bid for a period of sixty -one (61) days after the above bid opening date. The CITY OF ROSEMEAD will affirmatively insure the disadvantaged business enterprises will be afforded full opportunity to submit bids in response to this invitation and will not be discriminated against on the grounds of race, color, disability, sex or national origin in the consideration for an award. Pursuant to Section 1773 of the Labor Code, the general prevailing wage rates in the county, or counties, in which the work is to be done have been determined by the Director of the California NIB- 1 Department of Industrial Relations. These wages are set forth in the General Prevailing Wage Rates for this project available from the California Department of Industrial Relations' Internet web site at http://www.dir.ca.gov. The Federal minimum wage rates for this project as predetermined by the United States Secretary of Labor are set forth in the books issued for bidding purposes entitled "Proposal and Contract," and in copies of this book that may be examined at the offices described above where project plans, special provisions, and proposal forms may be seen. Addenda to modify the Federal minimum wage rates, if necessary, will be issued to holders of "Proposal and Contract" books. Future effective general prevailing wage rates, which have been predetermined and are on file with the California Department of Industrial Relations are referenced but not printed in the general prevailing wage rates. Attention is directed to the Federal minimum wage rate requirements in the books entitled "Proposal and Contract." If there is a difference between the minimum wage rates predetermined by the Secretary of Labor and the general prevailing wage rates determined by the Director of the California Department of Industrial Relations for similar classifications of labor, the Contractor and subcontractors shall pay not less than the higher wage rate. The Department will not accept lower State wage rates not specifically included in the Federal minimum wage determinations. This includes "helper" (or other classifications based on hours of experience) or any other classification not appearing in the Federal wage determinations. Where Federal wage determinations do not contain the State wage rate determination otherwise available for use by the Contractor and subcontractors, the Contractor and subcontractors shall pay not less than the Federal minimum wage rate, which most closely approximates the duties of the employees in question. The U.S. Department of Transportation (DOT) provides a toll -free "hotline" service to report bid rigging activities Bid rigging activities can be reported Mondays through Fridays, between 8:00 a.m. and 5:00 p.m., eastern time, Telephone No. 1- 800 - 424 -9071. Anyone with knowledge of possible bid rigging, bidder collusion, or other fraudulent activities should use the "hotline" to report these activities. The "hotline" is part of the DOT's continuing effort to identify and investigate highway construction contract fraud and abuse and is operated under the direction of the DOT Inspector General. All information will be treated confidentially and caller anonymity will be respected. Bidders shall be licensed in accordance with the provision of Chapter 9, Division 111 of the Business and Professions Code of the State of California. Bidder shall have a Class "C 20" license in good standing at the time Bids are received. The Council reserves the right to reject any and all bids and to waive any informality, technical defect, or minor irregularity in any bid submitted.

ADDENDA The Owner reserves the right to revise the Bid Documents prior to the bid opening date. Revisions, if any, shall be made by written Addenda. Pursuant to Public Contract Code Section 4104.5, if the Owner issues an Addendum later than 72 hours prior to the deadline for submission of bids, and the Addendum requires material changes, additions or deletions to the description of the work to be performed or the content, form or manner of submission of bids, the Owner will extend the deadline for submission of bids by at least 72 hours. Otherwise, the Owner may determine, in its sole discretion, whether an Addendum requires that the date set for opening bids be postponed.

Each prospective bidder shall provide Owner a name, address and facsimile number to which Bid Document Addenda may be sent, as well as a telephone number by which the Owner can contact the Bidder. Copies of Addenda will be furnished by telex, telegram, facsimile, first class mail, express mail or other proper means of delivery without charge to all parties who have obtained a copy of the Bid Documents and provided such current information. Please Note: Bidders are primarily and ultimately responsible for ensuring that they have received any and all Addenda. To this end, each Bidder should contact the Development Services Department to verify that he has received all Addenda issued, if any. Bidders must acknowledge receipt of all Addenda, if any, in its Bid Letter. Failure to acknowledge receipt of all Acift.- a may cause its Bid to be deemed incomplete and nonresponsive. 6. PREPARATION OF BIDS Bids shall be prepared only using copies of the Contract Bid Forms provided with the Bid Documents. The use of substitute bid forms other than clear and correct photocopies of those provided by the Owner will not be permitted and may result in the Bid being declared nonresponsive. Bid Letters shall be executed by an authorized signatory as described in these Instructions to Bidders. In addition, Bidders shall fill in all blank spaces (including inserting "N /A" where applicable) and initial all interlineations, alterations, or erasures to the Contract Bid Forms. Bidders shall neither delete, modify, nor supplement the printed matter on the Contract Bid Forms nor make substitutions thereon. USE OF INK, INDELIBLE PENCIL OR A TYPEWRITER IS REQUIRED. 7. ALTERNATE BIDS If alternate bid items are called for in the Bid Documents, the lowest bid will be determined ITB - 2 on the basis of the base bid only, but the Owner may choose to award the contract on the basis of the base bid alone or the base bid and any alternate or combination of alternates. Since the time for the alternate bid items has already been factored into the Contract Time, no additional Contract Time will be awarded for any of the alternate bid items. Because the Owner may elect to include one or more of the alternate bid items, or to otherwise remove certain bid items from the Project scope of work, each Bidder must ensure that each bid item contains a proportionate share of profit, overhead and other costs or expenses which will be incurred by the Bidder. Bidders shall not unevenly weight or allocate their overhead and profit to one or more particular bid items. 8. MODIFICATIONS OF BIDS Each Bidder shall submit its Bid in strict conformity with the requirements of the Bid Documents. Each Bid prepared by Bidder shall be complete in itself and shall be submitted within a sealed envelope in accordance with the instructions herein. Unauthorized conditions, limitations, exclusions or provisions attached to a Bid will render it nonresponsive and may cause its rejection. Bidders shall neither delete, modify, nor supplement the printed matter on the Contract Bid Forms, nor make substitutions thereon. ORAL, TELEPHONIC AND FACSIMILE BIDS OR MODIFICATIONS WILL NOT BE CONSIDERED. 9. SIGNING OF BIDS All Bids submitted shall be executed by the Bidder or its authorized representative. Bidders will be asked to provide evidence in the form of an authenticated resolution of its Board of Directors or a Power of Attorney evidencing the capacity of the person signing the Bid to bind the Bidder to each Bid and to any Contract arising therefrom. If a Bidder is a joint venture or partnership, it will be asked to submit an authenticated Power of Attorney executed by each joint venturer or partner appointing and designating one of the joint venturers or partners as a management sponsor to execute the Bid on behalf of Bidder. Only that joint venturer or partner shall execute the Bid.

The Bid shall be executed by the designated joint venturer or partner on behalf of the joint venture or partnership in its legal name. 10. BID GUARANTEE (BOND) Each bid proposal shall be accompanied by a certified or cashier's check, bid bond (the bid bond must be submitted on the form included in these Bid Documents) or equivalent substitution in lieu of a bond, as authorized by Code of Civil Procedure Section 995.710, in an amount not less than 10% of the Total Bid Price.

By submitting a proposal, each bidder agrees that its failure to enter the Contract if awarded the work or to provide the Bonds and other information or documentation described above would result in damage to the Owner, and that it would be impracticable or extremely difficult to ascertain the actual amount of that damage. For this reason, each bidder agrees that the Owner may retain the bid proposal guarantee as liquidated damages if the bidder is awarded the work but fails or refuses to timely enter into the Contract or to provide the Bonds and ITB - 3 other information or documentation described above, except as may otherwise be required by California law. If electing to provide a Bid Bond, as set forth above, each Bidder must obtain such a bond from an admitted surety insurer, as defined in Code of Civil Procedure Section 995.120, authorized to do business as such in the State of California and satisfactory to the Owner.

Certified or cashier's checks must be drawn on a solvent state bank or a California branch of a solvent national bank. After the Owner has made an award to the successful Bidder, and the Bidder has signed a Contract, submitted the necessary bonds, original insurance certificates and endorsements, and any other certifications as may be required by the Contract, the remaining Bid guarantees shall be returned to each particular bidder if requested by that bidder. If the Owner rejects all Bids, it will promptly return to all Bidders their Bid guarantees 11.

Any such coverage provided under an umbrella liability policy shall include a drop down provision providing primary coverage above a maximum $25,000 self- insured retention for liability not covered by primary but covered by the umbrella. Coverage shall be provided on a "pay on behalf' basis, with defense costs payable in addition to policy limits. Policy shall contain a provision obligating insurer at the time insured's liability is determined, not requiring actual payment by the insured first. There shall be no cross liability exclusion precluding coverage for claims or suits by one insured against another. Coverage shall be applicable to City for injury to employees of Consultant, subconsultants or others involved in the Work. The scope of coverage provided is subject to approval of City following receipt of proof of insurance as required herein. Limits are subject to review but in no event less than $ per occurrence.

Consultant and City agree to the following with respect to insurance provided by Consultant: 1. Consultant agrees to have its insurer endorse the third party general liability coverage required herein to include as additional insureds City, its officials, employees and agents, using standard ISO endorsement No. CG 2010 with an edition prior to 1992. Consultant also agrees to require all contractors, and subcontractors to do likewise. 2. No liability insurance coverage provided to comply with this Agreement shall prohibit Consultant, or Consultant's employees, or agents, from waiving the right of subrogation prior to a loss. Consultant agrees to waive subrogation rights against City regardless of the applicability of any insurance proceeds, and to require all contractors and subcontractors to do likewise. 3. All insurance coverage and limits provided by Contractor and available or amplicable to this agreement are intended to apply to the full extent of the policies. Nothing contained in this Agreement or any other agreement relating to the City or its operations limits the application of such insurance coverage. 4. None of the coverages required herein will be in compliance with these requirements if they include any limiting endorsement of any kind that has not been first submitted to City and approved of in writing. 5. No liability policy shall contain any provision or definition that would serve to eliminate so- called "third parry action over" claims, including any exclusion for bodily injury to an employee of the insured or of any contractor or subcontractor. 6. All coverage types and limits required are subject to approval, modification and additional requirements by the City, as the need arises. Consultant shall not make any reductions in scope of coverage (e.g. elimination of contractual liability or reduction of discovery period) that may affect City's protection without City's prior written consent. D -2 [insert Name of Company] Page 3 of [insert last page number of agreement] 7. Proof of compliance with these insurance requirements, consisting of certificates of insurance evidencing all of the coverages required and an additional insured endorsement to Consultant's general liability policy, shall be delivered to City at or prior to the execution of this Agreement. In the event such proof of any insurance is not delivered as required, or in the event such insurance is cancelec at any time and no replacement coverage is provided, City has the right, but not the duty, to obtain any insurance it deems necessary to protect its interests under this or any other agreement and to pay the premium. Any premium so paic by City shall be charged to and promptly paid by Consultant or deducted from sums due Consultant, at City option. 8. Certificate(s) are to reflect that the insurer will provide 30 days notice to City of any cancellation of coverage. Consultant agrees to require its insurer to modify such certificates to delete any exculpatory wording stating that failure of the insurer to mail written notice of cancellation imposes no obligation, or that any party will "endeavor' (as opposed to being required) to comply with the requirements of the certificate. 9. It is acknowledged by the parties of this agreement that all insurance coverage required to be provided by Consultant or any. subcontractor, is intended to apply first and on a primary, noncontributing basis in relation to any other insurance or self insurance available to City. 10. Consultant agrees to ensure that subcontractors, and any other party involved with the project who is brought onto or involved in the project by Consultant, provide the same minimum insurance coverage required of Consultant. Consultant agrees to monitor and review all such coverage and assumes all responsibility for ensuring that such coverage is provided in conformity with the requirements of this section. Consultant agrees that upon request, all agreements with subcontractors and others engaaed-in the project will be submitted to City for review. 11. Consultant agrees not to self- insure or to use any self- insured retentions or deductibles on any portion of the insurance required herein and further agrees that it will not allow any contractor, subcontractor, Architect, Engineer or other entity or person in any way involved in the performance of work on the project contemplated by this agreement to self- insure its obligations to City. If Consultant's existing coverage includes a deductible or self- insured retention, the deductible or self- insured retention must be declared to the City. At that time the City shall review options with the Consultant, which may include reduction or elimination of the deductible or selfinsured retention, substitution of other coverage, or other solutions. 12. The City reserves the right at any time during the term of the contract to change the amounts and types of insurance required by giving the Consultant ninety (90) days advance written notice of such change. If such change results in substantial D -3 [insert Name of Company] Page 4 of [insert last page number of agreement] additional cost to the Consultant, the City will negotiate additional compensation proportional to the increased benefit to City. 13. For purposes of applying insurance coverage only, this Agreement will be deemed to have been executed immediately upon any party hereto taking any steps that can be deemed to be in furtherance of or towards performance of this Agreement. 14. Consultant acknowledges and agrees that any actual or alleged failure on the part of City to inform Consultant of non - compliance with any insurance requirement in no way imposes any additional obligations on City nor does it waive any rights hereunder in this or any other regard. 15. Consultant will renew the required coverage annually as long as City, or its employees or agents face an exposure from operations of any type pursuant to this agreement. This obligation applies whether or not the agreement is canceled or terminated for any reason. Termination of this obligation is not effective until City executes a written statement to that effect. 16. Consultant shall provide proof that policies of insurance required herein expiring during the term of this Agreement have been renewed or replaced with other policies providing at least the same coverage. Proof that such coverage has been ordered shall be submitted prior to expiration. A coverage binder or letter from Consultant's insurance agent to this effect is acceptable. A certificate of insurance and /or additional insured endorsement as required in these specifications applicable to the renewing or new coverage must be provided to City within five days of the expiration of the coverages. 17.The provisions of any workers' compensation or similar act will not limit the obligations of Consultant under this agreement. Consultant expressly agrees not to mse any statutory immunity defenses under such laws with respect to City, its employees, officials and agents. 18. Requirements of specific coverage features or limits contained in this section are not intended as limitations on coverage, limits or other requirements nor as a waiver of any coverage normally provided by any given policy. Specific reference to a given coverage feature is for purposes of clarification only as it pertains to a given issue, and is not intended by any party or insured to be limiting or all - inclusive. 19-These insurance requirements are intended to be separate and distinct from any other provision in this agreement and are intended by the parties here to be interpreted as such. 20. The requirements in this Section supersede all other sections and provisions of this Agreement to the extent that any other section or provision conflicts with or impairs the provisions of this Section. M . [insert Name of Company] Page 5 of [insert last page number of agreement] 21. Consultant agrees to be responsible for ensuring that no contract used by any party involved in any way with the project reserves the right to charge City or Consultant for the cost of additional insurance coverage required by this agreement. Any such provisions are to be deleted with reference to City. It is not the intent of City to reimburse any third party for the cost of complying with these requirements. There shall be no recourse against City for payment of premiums or other amounts with respect thereto. Consultant agrees to provide immediate notice to City of any claim or loss against Consultant arising out of the work performed under this agreement. City assumes no obligation or liability by such notice, but has the right (but not the duty) to monitor the handling of any such claim or claims if they are likely to involve City.

PAYMENT BOND - 4 ROSEMEAD CITY HALL HVAC REPLACEMENT PROJECT PROJECT i0 Federal Labor Standards Provisions Applicability The Project or Program to which the construction work covered by this contract pertains is being assisted by the United States of America and the following Federal Labor Standards Provisions are included in this Contract pursuant to the provisions applicable to such Federal assistance. A. 1. (1) Minimum Wages. All laborers and mechanics em- ployed or working upon the site of the work will be paid uncondi- tionally and not less often than once a week, and without subse- quent deduction or rebate on any account (except such payroll deductions as are permitted by regulations issued by the Secre- tary of Labor under the Copeland Act (29 CFR Part 3), the full amount of wages and bona fide fringe benefits (or cash equiva- lents thereof) due at time of payment computed at rates not less than those contained in the wage determination of the Secretary of Labor which is attached hereto and made a part hereof, re- gardless of any contractual relationship which may be alleged to exist between the contractor and such laborers and mechanics. Contributions made or costs reasonably anticipated for bona fide fringe benefits under Section I(b)(2) of the Davis -Bacon Act on behalf of laborers or mechanics are considered wages paid to such laborers or mechanics, subject to the provisions of 29 CFR 5.5(a)(1)(iv); also, regular contributions made or costs incurred for more than a weekly period (but not less often than quarterly) under plans, funds, or programs, which cover the particular weekly period, are deemed to be constructively made or incurred during such weekly period. Such laborers and mechanics shall be paid the appropriate wage rate and fringe benefits on the wage determination for the classi- fication of work actually performed, without regard to skill, except as provided in 29 CFR 5.5(a)(4). Laborers or mechanics per- forming work in more than one classification may be compensated at the rate specified for each classification for the time actually worked therein: Provided, That the employer's payroll records accurately set forth the time spent in each classification in which work is performed. The wage determination (including any addi- tional classification and wage rates conformed under 29 CFR 5.5(a)(1)(ii) and the Davis -Bacon poster (WH-1 321) shall be posted at all times by the contractor and its subcontractors at the site of the work in a prominent and accessible, place where it can be easily seen by the workers. (ii) (a) Any class of laborers or mechanics which is not listed in the wage determination and which is to be employed under the contract shall be classified in conformance with the wage deter- mination. HUD shall approve an additional classification and wage rate and fringe benefits therefor only when the following criteria have been met: (1) The work to be performed by the classification requested is not performed by a classification in the wage determination; and (2) The classification is utilized in the area by the construction industry; and (3) The proposed wage rate, including any bona fide fringe ben- efits, bears a reasonable relationship to the wage rates contained in the wage determination. (b) If the contractor and the laborers and mechanics to be em- ployed in the classification (if known), or their representatives, and HUD or its designee agree on the classification and wage rate (including the amount designated for fringe benefits where U.S. Department of Housing and Urban Development Office of Labor Relations appropriate), a report of the action taken shall be sent by HUD or its designee to the Administrator of the Wage and Hour Division, Employment Standards Administration, U.S. Department of La- bor, Washington, D.C. 20210. The Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification action within 30 days of receipt and so advise HUD or its designee or will notify HUD or its designee within the 30 -day period that additional time is necessary. (Approved by the Office of Management and Budget under OMB control number 1215- 0140.) (c) In the event the contractor, the laborers or mechanics to be employed in the classification or their representatives, and HUD or its designee do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), HUD or its designee shall refer the questions, including the views of all interested parties and the recommenda- tion of HUD or its designee, to the Administrator for determina- tion. The Administrator, or an authorized representative, will is- sue a determination within 30 days of receipt and so advise HUD or its designee or will notify HUD or its designee within the 30 -day period that additional time is necessary. (Approved by the Office of Management and Budget under OMB Control Number 1215- 0140.) (d) The wage rate (including fringe benefits where appropriate) determined pursuant to subparagraphs (1)(ii)(b) or (c) of this para- graph, shall be paid to all workers performing work in the classifi- cation under this contract from the first day on which work is per- formed in the classification. (iii) Whenever the minimum wage rate prescribed in the contract for a class of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, the contractor shall either pay the benefit as stated in the wage determination or shall pay an- other bona fide fringe benefit or an hourly cash equivalent thereof. (iv) If the contractor does not make payments to a trustee or other third person, the contractor may consider as part of the wages of any laborer or mechanic the amount of any costs rea- sonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of the contrcv t,,r, g nat the applicable stan- dards of the Davis -Bacon Act have been met. The Secretary of Labor may require the contractor to set aside in a separate ac- count assets for the meeting of obligations under the plan or pro- gram. (Approved by the Office of Management and Budget under OMB Control Number 1215 - 0140.) 2. Withholding. HUD or its designee shall upon its own action or upon written request of an authorized representative of the De- partment of Labor withhold or cause to be withheld from the con- tractor under this contract or any other Federal contract with the same prime contractor, or any other Federally- assisted contract subject to Davis -Bacon prevailing wage requirements, which is held by the same prime contractor so much of the accrued pay- ments or advances as may be considered necessary to pay la- borers and mechanics, including apprentices, trainees and help- ers, employed by the contractor or any subcontractor the full amount of wages required by the contract. In the event of failure to pay any laborer or mechanic, including any apprentice, trainee or helper, employed or working on the site of the work, all or part form HUD -4010 (07/2003) Previous edition is obsolete Page 1 of 4 ref. Handbook 1344.1 of the wages required by the contract, HUD or its designee may, after written notice to the contractor, sponsor, applicant, or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased. HUD or its designee may, after written notice to the contractor, disburse such amounts withheld for and on account of the contractor or subcontractor to the respective employees to whom they are due. The Comptroller General shall make such disbursements in the case of direct Davis -Bacon Act contracts. 3. (i) Payrolls and basic records. Payrolls and basic records relating thereto shall be maintained by the contractor during the course of the work preserved for a period of three years thereaf- ter for all laborers and mechanics working at the site of the work. Such records shall contain the name, address, and social secu- rity number of each such worker, his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in Section I(b)(2)(B) of the Davis -bacon Act), daily and weekly number of hours worked, deductions made and actual wages paid.

Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs. (Approved by the Office of Management and Budget under OMB Control Numbers 1215 -0140 and 1215 - 0017.) (if) (a) The contractor shall submit weekly for each week in which any contract work is performed a copy of all payrolls to HUD or its designee if the agency is a party to the contract, but if the agency is not such a party, the contractor will submit the payrolls to the applicant sponsor, or owner, as the case may be, for transmission to HUD or its designee. The payrolls submitted shall set out ac- curately and completely all of the information, required to be main- tained under 29 CFR 5.5(aj(3)(i). This informu ion may be submit- ted in any form desired.

(i) Apprentices. Apprentices will be permitted to work at less than the predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. De- partment of Labor, Employment and Training Administration, Of- fice of Apprenticeship Training, Employer and Labor Services, or with a State Apprenticeship Agency recognized by the Office, or if a person is employed in his or her first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Office of Apprenticeship Training, Employer and Labor Services or a State Apprenticeship Agency (where appropriate). to be eligible for probationary employment as an apprentice: The allowable ratio of apprentices to journeymen on the job site in any craft classification shall not be greater than the ratio permitted to the contractor as to the entire work force under the registered program. Any worker listed on a payroll at an ap- prentice wage rate, who is not registered or otherwise employed as stated above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actu- ally performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where a contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the form HUD -4010 (07/2003) Previous edition is obsolete Page 2 of 4 ref. Handbook 1344.1 journeymen hourly rate specified in the applicable wage determi- nation. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the appren- ticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage deter- mination for the applicable classification. if the Administrator de- termines that a different practice prevails for the applicable ap- prentice classification, fringes shall be paid in accordance with that determination. In the event the Office of Apprenticeship Train- ing, Employer and Labor Services, or a State Apprenticeship Agency recognized by the Office, withdraws approval of an ap- prenticeship program, the contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is ap- proved. (ii) Trainees. Except as provided in 29 CFR 5.16, trainees will not be permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has received prior ap- proval, evidenced by formal certification by the U.S. Department of Labor, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Train- ing Administration. Every trainee must be paid at not less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program. If the trainee program does not mention fringe benefits, trainees shall be paid the full amount of fringe benefits listed on the wage determination unless the Administrator of the Wage and Hour Division determines that there is an apprentice- ship program associated with the corresponding journeyman wage rate on the wage determination which provides for less than full fringe benefits for apprentices. Any employee listed on the pay- roll at a trainee rate who is not registered and participating in a training plan approved by the Employment and Training Adminis- tration shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In addition, any trainee performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. In the event the Employment and Training Administration withdraws approval of a training program, the con- tractor will no longer be permitted to utilize trainees at less than the applicable predetermined rate for the work performed until an acceptable program is approved..

"Such adjustment of the Contract Unit Price will be the difference between the Contract Unit Price and the actual unit cost, which will be determined as hereinafter provided, of the total pay quantity of the item. If the costs applicable to such item of work include fixed costs, such fixed costs shall be deemed to have been recovered by the Contractor by the payments made for 125 percent of the Engineer's Estimate of the quantity for such item, and in computing the actual unit costs, such fixed costs will be excluded. Subject to the above provisions, such actual unit cost will be determined by the engineer in the same manner as if the work were to be paid for as extra work as provided in Paragraph 3 -3.2, as amended in these Special Provisions, or such adjustment as will be as agreed to by the Contractor and the Owner." "When the compensation payable for the number of units of an item of work performed in excess of 125 percent of the Engineer's Estimate is less than $5,000 at the applicable Contract Unit Price, the Engineer reserves the right to make no adjustment in said price if he so elects, except that an adjustment will be made if requested in writing by the Contractor."
