About this file

Written by GovTribe AI ·

This set of drawings and specifications is for a roof replacement project for the tower at the National Agricultural Library building. The project includes removing the existing EPDM roofing membrane, insulation, and vapor barrier down to the concrete deck. A new hot-applied rubberized asphalt protected roof membrane assembly will be installed with three layers of extruded polystyrene insulation and precast concrete pavers. New roof drains and metal flashing will also be provided at parapets, walls, and penetrations. The solicitation number for this project is 1232SA23R0012 and it is being conducted by the Department of Agriculture's Agricultural Research Service for their National Agricultural Library facility.
