S.C. Code Ann. § 57-5-1720: County-funded projects; highway construction contracts.

(A) The department may award highway construction contracts using a construction manager/general contractor (CM/GC) procedure. Under a CM/GC contract, the department shall perform preconstruction services via department personnel or via contract. A CM/GC contractor is responsible for providing advisory preconstruction services of the department's design including, but not limited to, constructability review, scheduling, pricing, and phasing. The CM/GC contractor shall be able to perform construction should the department and the contractor agree to a guaranteed maximum price.

(B) Should a guaranteed maximum price agreement be reached, construction services shall commence under a subsequent contract instrument. The contract instrument may be in the form of a CM/GC contract, a franchise agreement, or any other form of contract approved by the department. Before execution of a construction contract, the department shall retain an independent third party to develop a cost estimate to verify the guaranteed maximum price submitted by the contractor.

(C) Selection criteria shall include the contractor's cost for preconstruction services associated with the project, contractor qualifications, experience, past performance, best value, or any combination of the aforementioned criteria, or any other combination of selection criteria considered appropriate by the department.

(D) The department may promulgate regulations to implement the CM/GC project delivery method.
