Mississippi's precast concrete drainage work on state projects is governed by the Mississippi Department of Transportation (MDOT). The requirements for drainage structures, reinforced concrete pipe, box culverts, and the concrete itself live in the Mississippi Standard Specifications for Road and Bridge 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.
MDOT plans present a Summary of Quantities sheet that lists work by pay item. Drainage items are tabulated as pay items such as reinforced concrete pipe by size and class, precast concrete box culvert by size, and manholes, inlets, and catch basins. Quantities on the plans are primarily for estimating, and field verification governs final measurement and payment.
Mississippi Standard Specifications for Road and Bridge Construction, 2017 Edition (adopted November 8, 2016). The sections below cover precast drainage structures, pipe, culverts, and concrete.
| Section | Title |
|---|---|
| 601 | Structural Concrete (includes 601.02.3 Precast Units) |
| 602 | Reinforcing Steel |
| 603 | Culverts and Storm Drains (includes precast box culverts and headwalls) |
| 604 | Manholes, Inlets and Catch Basins |
| 708 | Non-Metal Structures (includes Reinforced Concrete Pipe and Precast Concrete Box Culvert) |
| 711 | Reinforcement and Wire Rope |

The 2017 Standard Specifications approve precast units on a per-project basis rather than through a single published precast approved-source list. Under 601.02.3 a contractor may request approval to furnish precast units in lieu of cast-in-place by submitting detailed drawings and design data certified by a registered Professional Engineer.
Plant certification: Per-project approval under Subsection 601.02.3. Registered Professional Engineer certification per Subsection 601.02.3; precast sectional manholes conform to AASHTO M 199. No named third-party plant-certification program appears in the Standard Specifications.

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 2017 Mississippi Standard Specifications for Road and Bridge Construction. Section 603 addresses culverts and storm drains, Section 604 addresses manholes, inlets, and catch basins, and Section 708 provides the material requirements for reinforced concrete pipe and precast concrete box culverts.
Yes. Under Subsection 601.02.3, a contractor may request Engineer approval to furnish precast units in place of cast-in-place units by submitting detailed drawings and design data certified by a registered Professional Engineer for structural and functional adequacy.
Section 604 provides that precast sectional manholes conform to AASHTO M 199, the standard specification for precast reinforced concrete manhole sections.
Construction requirements are in Section 603 and material requirements are in Section 708, Precast Concrete Box Culvert. Pay items appear on the plan Summary of Quantities by box size.
