Proposers must hold a current, active Florida engineering license at proposal submission; a Surveying and Mapping certification may be provided through a subconsultant.

Evaluation criteria consist of response quality (maximum 100 points), SBE participation bonus (maximum 5 points), volume of work based on two prior fiscal years' payments (maximum 5 points), and past performance ratings (maximum 5 points). Compensation is structured as time-and-expense or lump-sum arrangements negotiated per work order, with personnel billing rates derived from audited or certified direct salary multipliers.
