O.C.G.A. § 50-27-30: Bidding requirements and procedures for contracts.

(a) The corporation shall enter into its contracts for major procurements after competitive bidding. The requirement for competitive bidding does not apply in the case of a single vendor having exclusive rights to offer a particular service or product. Procedures adopted by the board shall be designed to allow the selection of proposals that provide the greatest long-term benefit to the state, the greatest integrity for the corporation, and the best service and products for the public.

(b) In any bidding process, the corporation may administer its own bidding and procurement or may utilize the services of the Department of Administrative Services or other state agency or subdivision thereof.
