About this file
This document contains specifications for glazing materials and installation for the VA Northern Indiana Healthcare System project to Expand Building 1, First Floor Primary Care in Fort Wayne, Indiana. The specifications require clear, heat-treated, coated, laminated, insulating, and fire-protective glass units to meet standards for thickness, light transmission, solar heat gain, fire ratings, and safety glazing. Metal accessories must match aluminum finishes. Installation methods include dry, wet/dry and wet techniques for sealants, gaskets and tapes. The project also includes a monolithic and insulating/laminated glass schedule.
The related federal contract opportunity is solicitation number 36C25020B0004 for the Y1DA--Expand First Floor B-1 for PACT project at the VA Northern Indiana Healthcare System in Fort Wayne, Indiana.
