Subject to the requirements of this section, an agency making use of the provisions of this part 11 may award any type of contract that will promote the best interests of the agency; except that the use of a cost-plus-a-percentage-of-cost contract under this part 11 is prohibited. An agency may award a cost-reimbursement contract only when a determination is made in writing that such contract is either likely to be less costly to the agency than any other type of contract or that it is impracticable to obtain the required construction or other services authorized under this part 11 unless the cost-reimbursement contract is used. Operation and maintenance elements may be procured on a cost-reimbursement basis under or in connection with an IPD contract.L. 2007: Entire part added, p. 1814, § 2, effective August 3.
