Vermont's precast concrete drainage work on state projects is governed by the Vermont Agency of Transportation (VTrans). The requirements for drainage structures, reinforced concrete pipe, box culverts, and the concrete itself live in the Standard Specifications for Construction, 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.
VTrans drainage work appears in the 600-series pay items, with structures counted under Section 604 (drop inlets, catch basins, manholes) and pipe measured by linear foot under Section 601, where reinforced concrete pipe is grouped by diameter and class. Quantities tie back to the Master Pay Item List item numbers. The exact column layout of the plan drainage tabulation sheet could not be confirmed from a public VTrans source.
Standard Specifications for Construction, 2024 (replaced the 2018 edition). The sections below cover precast drainage structures, pipe, culverts, and concrete.
| Section | Title |
|---|---|
| 540 | Precast Concrete |
| 543 | Contractor-Fabricated Precast Concrete Structure |
| 601 | Culverts and Storm Drains |
| 604 | Drop Inlets, Catch Basins, and Manholes |
| 710 | Culverts, Storm Drains, and Sewer Pipes, Nonmetal |
| 713 | Concrete Reinforcing Materials |
Section numbers are a reference. Confirm them against the current specification and any special provisions for your project.
Construction standard drawings are published through the CADD downloads area and grouped by owner (Design and Drainage Features, Structures, Utilities, and others). The drainage details use D-series drawing numbers for manholes, catch basins, and precast box culverts. Structures detail sheets are a separate complete-set PDF.
The Structural Materials unit maintains an Approved Concrete and Precast Producers list covering ready-mix and precast production facilities approved for use on Agency projects, alongside a broader Approved Products program and submittal process.
Plant certification: Precast plant qualification under Standard Specifications Section 540.03. NPCA or PCI third-party plant certification required by specification; VTrans adds its own Qualified Laboratory Program requirements and plant inspection.

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.
See DhyanaERP Precast EditionThe 2024 Standard Specifications for Construction is the current edition. It replaced the 2018 edition and governs Vermont Agency of Transportation projects.
Section 604 covers drop inlets, catch basins, and manholes, including precast reinforced concrete units. Section 601 covers culverts and storm drains measured by the foot. Section 710 covers nonmetal pipe materials, including reinforced concrete pipe and concrete pipe end sections. Section 540 covers precast concrete structure components.
Yes. Section 540.03 requires precast concrete to be manufactured in a plant certified under the NPCA or PCI plant certification program, and the plant must maintain a quality control laboratory meeting the Agency Qualified Laboratory Program.
The Structural Materials unit maintains an Approved Concrete and Precast Producers list, published through the Approved Materials, Products, Producers, and Laboratories pages.
