About this file
This is a specifications document from the Missouri Department of Transportation (MoDOT) for the procurement of corrugated metallic-coated steel culvert pipe, pipe-arches, and end sections for maintenance purposes in the I-44 Corridor Area within MoDOT's Southwest District. The specifications establish material requirements and ordering parameters for corrugated metal pipe (CMP) and aluminized culverts that must comply with applicable MoDOT standards, including Specifications Sections 725, 1020, and 1022. Acceptable corrugation dimensions are either 2 2/3 by 1/2 inch or 3 by 1 inch, with pipe ends requiring 2 2/3 by 1/2 inch annular corrugations extending at least 4 corrugations from the end. Pipe lengths must be ordered in 2-foot increments, and connecting bands shall be a minimum of 24 inches in width with annular corrugations unless otherwise specified. This is a one-time purchase with no specified quantities, delivery dates, or award dates documented in the specifications.
The metallic coating may be either zinc or aluminum at the vendor's discretion unless otherwise noted in the bid request, with specific coating requirements to be designated in the order as needed. The sheet thickness of coated pipe shall correspond to allowable overfill heights as detailed in MoDOT Standard Plan 725.00A Table 1 based on the specified pipe diameter and corrugation type. Material acceptance will be conducted in accordance with Specification Section 1020. No pricing information, set-asides, incumbent contractor details, funding sources, or contract term information is provided in these technical specifications.
