Minnesota's precast concrete drainage work on state projects is governed by the Minnesota Department of Transportation (MnDOT). The requirements for drainage structures, reinforced concrete pipe, box culverts, and the concrete itself live in the Standard Specifications for Construction, 2025, 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 MnDOT 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 MnDOT presents drainage structures on plan sets.
Standard Specifications for Construction, 2025. 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 and Standard Plans include precast drainage items such as catch basins, manholes, and adjusting rings.
Covers precast box culverts, pipe and manhole plants, adjusting rings, headwalls, and other precast concrete categories.

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.
