About this file
This is a specification document for corrugated metallic-coated steel culvert pipe issued by the Missouri Department of Transportation (MoDOT) for maintenance purposes. The specification (MGS-91-11G) establishes material standards and requirements for corrugated metal culvert pipe, pipe-arches, end sections, and connecting bands that vendors must meet to supply to MoDOT's Southwest District. The pipe and bands must comply with applicable sections of MoDOT Specifications 725, 1020, and 1022, with metallic coatings available in either zinc or aluminum. Acceptable corrugations are limited to either 2 2/3 by 1/2 inch or 3 by 1 inch configurations, with pipe ends requiring 2 2/3 by 1/2 inch annular corrugations extending at least 4 corrugations from the pipe end. Metal arch pipe (B1 through B4) must comply with AASHTO M 36 dimensional requirements. Bands must be annular corrugated over their entire width with a minimum width of 24 inches unless otherwise specified in the order, with alternate options for dimple or formed band types when permitted.
Specific diameter, quantity, length, and band specifications are to be detailed in individual purchase orders, with pipe lengths required in 2-foot increments. Vendors may specify a preferred metallic coating as "Zinc Coated" or "Aluminum Coated" in their orders if a specific type is desired. All material will be accepted in accordance with MoDOT Specification Section 1020, which establishes the acceptance and testing criteria. The procurement represents a one-time purchase by MoDOT's Southwest District, and vendors must certify that all end products meet the attached specifications.
