Westwood - Thorne Elementary Partial Roof Replacement

Westwood Community Schools is soliciting sealed bids for a partial roof replacement at Thorne Elementary School, 25251 Annapolis Street, Dearborn Heights, Wayne County, Michigan, with bids due 11:00 a.m. on November 4, 2026. Westwood will buy the Garland-supplied roofing materials directly through the OMNIA Partners program, so contractors must exclude those materials from their pricing and submit a separate form listing anticipated material quantities.

The base bid covers Sections 2, 3, and 13, totaling approximately 22,450 square feet, with alternate bids for Sections 11, 12, and 14. The work includes removing the existing roof to deck and installing a 2-ply modified bituminous membrane system (identified as an HPR modified roof system in the bid advertisement), along with tapered polyisocyanurate insulation, expansion joints, raised curbs, and counter-flashing at high walls. Decking varies by section among gypsum, metal, and concrete. Contractors must also submit unit prices for potential wood blocking, metal decking, drain, gypsum decking, and concrete decking replacement or repair. Required submittals and conditions include a bid bond, a performance and payment bond, contractor-obtained building permits, OSHA compliance, workers' compensation and general liability insurance with minimum limits of $1 million, and a competent superintendent on site during all operations.

Addendum #1 states that bid quantities will be cross-referenced against an expected project take-off, and bids with quantities substantially above or below anticipated requirements may be rejected without detailed explanation. Bidders bear responsibility for the quantities they enter, and any additional materials will be billed directly to the bidder. The project warranty package includes a 30-year manufacturer warranty and a 3-year contractor workmanship warranty, with a 10 percent retainer held until warranty delivery. Work must start by November 19, 2026, and finish by August 15, 2027, with a $300 daily penalty for overruns. Final payment is due within 30 days of project approval. The mandatory pre-bid conference was held October 27, 2026, at 11:00 a.m. at the school site. Bid documents are available through BidNet, and the contact is Patrick Addison.
