Ohio's precast concrete drainage work on state projects is governed by the Ohio Department of Transportation (ODOT). The requirements for drainage structures, reinforced concrete pipe, box culverts, and the concrete itself live in the Construction and Material Specifications (C&MS), 2023, 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 ODOT 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 ODOT presents drainage structures on plan sets.
Construction and Material Specifications (C&MS), 2023. 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.
Includes a drainage and hydraulic set with catch basin and drainage miscellaneous drawings for catch basins, inlets, and manholes.
Lists pipe and materials categories; data is being transitioned into AASHTOWare Project, so some categories may be unavailable.

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.
