Description

The South Dakota Department of Transportation (SDDOT) is seeking Statements of Interest and Qualifications (SOI) from consulting firms to add them to a pre‑qualified consultant retainer list for the remainder of the 2026‑2028 contract period. The indefinite‑quantity retainer will allow selected firms to receive individual work orders across a wide range of transportation‑related categories (e.g., bridge design, roadway design, geotechnical services, environmental studies). Firms are evaluated on expertise, resources, past performance, local availability, project‑management approach, and ability to handle special constraints. Submissions must be in PDF (DOT‑925) and emailed to the designated contact by the deadline.

Budget estimate

$500,000 – $5,000,000

No specific dollar values are disclosed. Based on typical state‑wide transportation consulting retainer programs, annual retainer fees for each selected firm can range from a few hundred thousand dollars to over a million, depending on the number and complexity of work orders secured. Assuming a firm wins multiple work orders across the 2‑year period, total earnings could plausibly fall between $0.5 million and $5 million. Factors influencing the final amount include the number of categories the firm is qualified for, the volume of work orders issued, hourly rates or fixed‑price contracts for each task, and any reimbursable expenses.
