The Jennie Sealy Hospital project is a new hospital located on the University of Texas Medical Branch (UTMB) campus in Galveston, Texas. The new, 13-story, 758,000 sq. ft. building is best described as a concrete framed structure with exterior cladding consisting of architectural precast panels, impact-resistant glazed aluminum curtain walls and metal wall panels. The roof system is a low-slope modified bitumen system over polyisocyanurate insulation. The building is directly adjacent to the new Clinical Services Wing (CSW) and Building 21. Z6 Commissioning (Z6) was commissioned by the University of Texas OFPC to provide performance testing of building envelope components. The scope included chamber testing of window systems, nozzle testing 50% of windows and transitions between wall and roof assemblies, roof uplift testing, and electronic leak detection services. The Z6 Commissioning team also utilized our full-service performance testing laboratory in Galveston to test two 20ft x 30ft mock-ups for performance assurance consisting of the window systems, pre-cast panels, metal panels and the curtain wall.
