Thornley Campus Building 920 Roof Replacement - Phase 1

This project involves the complete replacement of the roof on Building 920 of the Thornley Campus, including deck repairs, insulation, a modified bitumen roofing system, and all related sheet metal components. The base scope covers approximately 895 squares, with two optional alternates that add roughly 864 squares and 86 squares respectively, allowing the contractor to bid on a larger or smaller footprint as needed. The work follows a Design‑Bid‑Build delivery method and requires a licensed Roofing (RF) contractor. • Base bid: replace roof for ~895 squares (≈89,500 sf) with deck repair, insulation, and modified‑bitumen system. • Alternate #1: add ~864 squares (≈86,400 sf) to the base scope. • Alternate #2: add ~86 squares (≈8,600 sf) to the base scope. • All work must comply with design‑drawings and include associated sheet‑metal work, accessories, and warranty provisions.
