This document is Addendum No. 1 for the MDOT - Engadine Garage Roof Replacement project, issued by U.P. Engineers & Architects, Inc. on April 10, 2025. The addendum modifies the original bid specifications for a roof replacement project at the Engadine Garage in Engadine, Michigan. Key changes include extending the bid due date to April 30, 2025 at 2:00 P.M. Eastern Time, adding acceptable membrane substitutions (Duro-Tuff 80 membrane and IB PVC Single Ply 80 Mil membrane), and providing demolition details such as removing two top courses of CMU and existing roof membrane. The addendum also requires contractors to attend a mandatory pre-bid walkthrough, register for state-funded projects, and include State Project Registry (SPR) documentation with their bid proposal.
The addendum includes specific technical modifications, such as replacing the DC specification book, detailing roof drain replacement at six locations, and requiring contractors to taper the roof to all roof drains. Additional requirements include reviewing an attached asbestos report and connecting new roof drains to existing 6" drain pipes. Contractors must verify existing pipe sizes and follow the attached roof drain detail. The project involves removing existing roof membrane, insulation, and drains, with existing roof thickness ranging from 5" to 7" depending on the roof section. Bidders must acknowledge receipt of the addendum on the bid form and include it with their proposal package.
