In consultation with the Michigan Municipal League and the County Road Association of Michigan, MDOT had revised the culvert and storm sewer pipe material policy on federally funded local agency projects. With the passage of MAP-21, MDOT will return autonomy to the Local Agencies for the selection of pipe material.

MDOT will no longer require the use of pay items that leave the selection of the material up to the contractor by using MDOT Standard Pay Items for sewer and culvert pipe with pay item descriptions of “Class A thru E.” The Local Agency may now specify the pipe material utilizing MDOT Standard Pay Items or by their own Special Provision and utilization of unique pay items.

A full description of the culvert and storm sewer pipe material policy on federally funded local agency projects can be found below.
