About this file
This is a bid specification document for Taylor Public Schools in Michigan detailing requirements for roof removal and replacement work at the K-9 Academy Training Facility located at 24800 Hayes St, Taylor, MI 48180. The project encompasses the complete replacement of Roof A, totaling 11,550 square feet with a slope of 1 inch per 12 inches. The scope of work includes full roof tear-off of the existing aggregate-surfaced built-up roofing system, removal and reinstallation of roof components, installation of a new three-ply cold-applied built-up asphalt roofing system with polyisocyanurate insulation, and installation of sheet metal flashing and trim. The specification is based on Tremco roofing products and requires compliance with NRCA and FM standards. The contractor must provide a qualified installer with a minimum of five years' experience, and the roofing system includes a 20-year manufacturer's warranty and a 2-year installer's warranty. Work is restricted to normal business hours of 7:00 a.m. to 5:00 p.m., Monday through Friday, with 72 hours' notice required for activities affecting owner operations, and the facility will remain occupied during construction.
The specification establishes five unit price categories for potential change orders: deck material replacement (per square foot), re-tap drain bolts (per set), roof drain replacement (per unit), new clamping rings (per unit), and existing wood nailer replacement (per board foot in 2"x4", 2"x6", and 2"x8" sizes). All unit prices must include material, delivery, installation, insurance, overhead, and profit. The contractor is responsible for all demolition waste removal and disposal, temporary roofing protection during work, and protection of the occupied building. The document mandates compliance with EPA notification regulations for asphalt removal, environmental protection requirements, dust and noise control measures, drug and background screening of contractor personnel, and employee identification badges. Manufacturer's inspection services are included in the contract sum, with inspections scheduled for years 2, 5, 10, and 15 following completion. The project document date is October 8, 2026, and the roofing advisor is Jamie O'Shee at Tremco, (800) 562-2728.
