South Dakota's precast concrete drainage work on state projects is governed by the South Dakota Department of Transportation (SDDOT). The requirements for drainage structures, reinforced concrete pipe, box culverts, and the concrete itself live in the Standard Specifications for Roads and Bridges, 2026, with details carried on the state's standard drawings. Precast producers read those documents alongside the project plan set to know what to make and how it will be accepted.
This page links the core SDDOT documents a precast producer or estimator uses: the standard specifications, standard drawings, approved products, and where bid plans are posted. We are still documenting how SDDOT presents drainage structures on plan sets.
Standard Specifications for Roads and Bridges, 2026. The sections below cover precast drainage structures, pipe, culverts, and concrete.
Section numbers are a reference. Confirm them against the current specification and any special provisions for your project.
Standard Plates include series 450 Pipe Culverts and 560 Precast Concrete Box Culverts.
Carries drainage categories such as culvert repair, drainage fabric, and pipe, but no explicit precast concrete category.

DhyanaERP Drainage Summary Import reads a plan set, finds the drainage structure sheets, transcribes them under a strict extraction contract, checks the engineering, and turns each row a person confirms into a priced structure. This status describes DhyanaERP's reading capability only. It is not a statement of DOT approval.
