Description

This solicitation invites qualified contractors to submit sealed bids for the complete replacement of the roof on McKean High School. The project entails demolition of the existing roof, installation of a new roofing membrane (EPDM or Modified Bitumen), metal flashing, gutters, downspouts, roof‑access accessories, and associated sealants and high‑performance coatings. The bid process is sealed, with a mandatory pre‑bid meeting and a 10 % bid security; performance and payment bonds equal to 100 % of the contract price will be required upon award. • Demolition of existing roof assembly and disposal of debris. • Installation of new roofing system (membrane, flashings, gutters, accessories). • Required testing (flood, infrared, electrical, nuclear‑hydrogen) and manufacturer inspection before substantial completion. • Warranty documentation (2‑yr sealant, 5‑yr coating, 20‑yr metal‑flashing).

Budget estimate

$1,000,000 – $2,500,000

The project is a full roof replacement for a high‑school facility, which typically ranges from $1 million to $2.5 million depending on square footage, membrane type, and ancillary work (flashing, testing, warranties). Assuming a medium‑size high‑school roof (≈25,000 sq ft) and a mid‑range membrane system, the contract value is likely in the $1.2 M–$2 M band. This estimate accounts for material costs, labor (including prevailing‑wage rates), bonding, and contingencies.
