About this file
This is a Substitution Request form and RFI (Request for Information) documentation related to the Bert Goens Learning Center Pool Improvements project for Van Buren ISD in Michigan. The request, submitted on June 5, 2026, concerns sanitary waste piping specialties for trench drains and shower channel drains specified under Section 22 13 19 of the project specifications. The primary request involves substituting MIFAB P9000 series stainless steel shower channels with a custom 24-inch length configuration to accommodate the project's specific application requirements, as the standard MIFAB product line only offered lengths starting at 27 inches.
The substitution request was officially reviewed and approved on June 9, 2026, by Skylar Andrae of GMB (the project's management entity), with the determination that the custom-sized product aligns with the basis of design and can proceed. The approved substitution specifies the use of electro-polished Type 304 stainless steel channels with various grate pattern options (Quatro, Subway, Tile Inlay, Wave, Wedgewire, and Perimeter designs), each weighing 7.50 pounds. The supporting documentation indicates that MIFAB can manufacture the custom 24-inch length to accommodate this application, and submittals were required to proceed in accordance with Specification Section 01 25 00 Substitution Procedures. No cost or schedule impacts were identified as a result of this substitution approval.
