A&E Services, Consultant Services Retainer

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.
