S.D. Codified Laws § 5-18B-36
After obtaining and evaluating proposals according to the criteria and procedures set forth in the design-build request for proposals, a purchasing agency may accept the proposal it considers most advantageous to the purchasing agency. Acceptance of a proposal shall be by written notice to the design-builder which submitted the accepted proposal. At the same time notice of acceptance is delivered, the purchasing agency shall also inform, in writing, the other design-builders that their proposals were not accepted. Unless all proposals are rejected, a detailed breakdown of the evaluation criteria scores for each proposal received shall be made available to the public after signature execution of the design-build contract. The contract for development of performance criteria shall terminate if a contract is awarded to the design-builder.
