About this file
This specification document from the Missouri Department of Transportation (MoDOT) establishes material requirements for corrugated metallic-coated steel culvert pipe, pipe-arches, and end sections for maintenance purposes in the Southwest District. The specifications detail requirements for pipe and connecting bands, including material compliance with applicable MoDOT sections (725, 1020, and 1022), metallic coating options (zinc or aluminum), and corrugation dimensions (either 2 2/3 by 1/2 inch or 3 by 1 inch). Pipe ends must feature 2 2/3 by 1/2 inch annular corrugations extending at least 4 corrugations from the pipe end, with certain pipes requiring re-rolling. Metal arch pipes B1 through B4 must comply with AASHTO M 36 dimensional requirements. Bands shall be annular corrugated over their entire width with 2 2/3 by 1/2 inch corrugations and have a minimum width of 24 inches unless otherwise specified in the order.
Ordering specifications require that pipe diameters comply with Specification Section 725, pipe lengths be provided in 2-foot increments, and specific metallic coating designations ("Zinc Coated" or "Aluminum Coated") be included in orders if specific coatings are desired. Alternate band types, including dimple or formed configurations, are permissible when allowed by the order. Material acceptance is governed by Specification Section 1020, requiring vendor certification that all end products meet the attached MoDOT specifications. This is identified as a one-time purchase opportunity by MoDOT's Southwest District.

3.0 ORDERING INFORMATION.
3.1 Specific diameter and quantity information for pipe and bands, and lengths for pipe, are to be shown in the order. Acceptable diameters are shown in Specification Sec 725. Pipe lengths are to be in 2 foot increments.
3.2 Specific band information for type and width is to be shown in the order only if different from that specified herein. Alternate band types are dimple or formed, when allowed by the order.
