About this file

Written by GovTribe AI · Aug 26, 2025

These documents are architectural and engineering drawings for a Public Works Complex Roof Replacement and PV Design Contract for Radnor Township, located in Delaware County, Pennsylvania. The project involves a comprehensive roof replacement and photovoltaic (PV) design for multiple buildings within the township's public works complex, including the Garage & Office Building, North Shed, Break Room Building, and Salt Shed. The project is being prepared by Spotts, Stevens & McCoy (SSM), an engineering consulting firm, and was initially issued for bid on 03/21/25, with subsequent reissues on 05/23/25 and 08/21/25. The contract includes full roof tear-off, replacement of existing roofing systems with a new 80-mil TPO membrane roofing system, installation of new rigid insulation, and integration of photovoltaic arrays on multiple building roofs.

The project includes detailed specifications for roofing materials, including a 30-year warranty TPO roofing membrane with R-30 insulation, vapor barriers, and comprehensive flashing and penetration details. The scope encompasses removing existing roofing, inspecting and potentially replacing roof decking, reinstalling salvaged equipment like exhaust fans and condensing units, and adding new roof access features. The drawings provide extensive technical details for roof replacement, including specific instructions for membrane installation, penetration sealing, edge treatments, and PV array mounting. Unit pricing is requested for potential additional work such as metal roof deck replacement and perimeter blocking replacement. The project appears to be funded through the township's capital improvement or infrastructure budget, with a focus on energy efficiency and long-term building envelope performance.
