Amendment 0005 - Attachment C NSWC PNYA Roofs (Revised).xlsx

This file is an attachment listing roof inventory and specifications for buildings located at Naval Support Weapons Center Philadelphia Naval Yard Area (NSWC PNYA). The spreadsheet catalogs approximately 30 buildings with detailed roof information including roof type, approximate square footage, pitch, parapet details, construction dates, manufacturer warranties, and roof access methods. Roof types vary widely and include corrugated aluminum, asphalt built-up systems, standing seam painted aluminum, modified bitumen, TPO (thermoplastic polyolefin), and EPDM membranes. Square footage ranges from approximately 484 SF to 106,150 SF per roof section, with construction dates spanning from approximately 1980 to 2012. Warranty information indicates coverage periods ranging from 5 to 20 years from various manufacturers including MuleHide, Tremco, GAF, Johns Manville, and others.

The inventory identifies roof access methods as either exterior ladders, high-reach access, internal stairs/elevators, or penthouse access, which will be relevant for determining maintenance and replacement approach requirements under the associated IDIQ roofing maintenance and replacement contract. This comprehensive facility data serves as baseline documentation for the roofing services contract covering Department of Navy installations at Philadelphia Naval Business Center, Naval Support Activity Philadelphia, and Naval Support Activity Mechanicsburg, enabling contractors to understand the scope and diversity of roofing systems that may require repair, replacement, or maintenance work during the contract period.
