Section 635.504 - CM/GC Requirements(a)In general. A contracting agency may award a two-phase contract to a CM/GC contractor for preconstruction and construction services. The first phase of this contract is the preconstruction services phase. The second phase is the construction services phase. The construction services phase may occur under one contract or under multiple contracts covering portions of the project, including early work packages.(b)Procurement requirements.(1) The contracting agency may procure the CM/GC contract using applicable State or local competitive selection procurement procedures as long as those procedures do not serve as a barrier to free and open competition or conflict with applicable Federal laws and regulations.(2) Contracting agency procedures may use any of the following solicitation options in procuring a CM/GC contract: Letters of interest, requests for qualifications, interviews, request for proposals or other solicitation procedures provided by applicable State law, regulation or policy. Single-phase or multiple-phase selection procedures may also be used.(3) Contracting agency procedures shall require, at a minimum, that a CM/GC contract be advertised through solicitation documents that:(i) Clearly define the scope of services being requested;(ii) List evaluation factors and significant subfactors and their relative importance in evaluating proposals;(iii) List all required deliverables;(iv) Identify whether interviews will be conducted before establishing the final rank (however, the contracting agency may reserve the right to make a final determination whether interviews are needed based on responses to the solicitation); and(v) Include or reference sample contract form(s).(4) If interviews are used in the selection process, the contracting agency must offer the opportunity for an interview to all short listed firms (or firms that submitted responsive proposals, if a short list is not used). Also, if interviews are used, then the contracting agency must not engage in conduct that favors one firm over another and must not disclose a firm's offer to another firm.(5) A contracting agency may award a CM/GC contract based on qualifications, experience, best value, or any other combination of factors considered appropriate by the contracting agency and the Division Administrator and which are clearly specified in the solicitation documents.(6) In the event that the contracting agency is unwilling or unable to enter into a contract with the CM/GC contractor for the construction services phase of the project (including any early work package), after the concurrence of the Division Administrator, the contracting agency may initiate a new procurement process meeting the requirements of subpart A of this part, or of another approved method for the affected portion of the construction work. If Federal-aid participation is being requested in the cost of construction, the contracting agency must request FHWA's approval before advertising for bids or proposals in accordance with § 635.112 and part 636 of this chapter. When the contracting agency makes a decision to initiate a new procurement, the contracting agency may determine that the CM/GC contractor is likely to have a competitive advantage that could adversely affect fair and open competition and not allow the CM/GC contractor to submit competitive bids.(c)FHWA approval of CM/GC procedures.(1) The STA must submit its proposed CM/GC procurement procedures to the FHWA Division Administrator for review and approval. Any changes in approved procedures and requirements shall also be subject to approval by the Division Administrator. Other contracting agencies may follow STA approved procedures, or their own procedures if approved by both the STA and FHWA.(2) The Division Administrator may approve procedures that conform to the requirements of this subpart and which do not, in the opinion of the Division Administrator, operate to restrict competition. The Division Administrator's approval of CM/GC procurement procedures may not be delegated or assigned to the STA.(d)Subcontracting. Consistent with § 635.116(a) , contracts for construction services must specify a minimum percentage of work (no less than 30 percent of the total cost of all construction services performed under the CM/GC contract, excluding specialty work) that a contractor must perform with its own forces. If required by State law, regulation, or administrative policy, the contracting agency may require the CM/GC contractor to competitively let and award subcontracts for construction services to the lowest responsive bidder.(e)Payment methods.(1) The method of payment to the CM/GC contractor shall be set forth in the original solicitation documents, contract, and any contract modification or change order thereto. A single contract may contain different payment methods as appropriate for compensation of different elements of work.(2) The methods of payment for preconstruction services shall be: Lump sum, cost plus fixed fee, cost per unit of work, specific rates of compensation, or other comparable payment method permitted in State law and regulation. When compensation is based on actual costs, an approved indirect cost rate must be used. The cost plus a percentage of cost and percentage of construction cost methods of payment shall not be used.(3) The method of payment for construction services may include any method of payment authorized by State law (including, but not limited to, lump sum, unit price, and target price). The cost plus a percentage of cost and percentage of construction cost methods of payment shall not be used.
