SGH assisted with the design for the window walls and fiber-cement rainscreen cladding. Highlights of our work include the following:

• Reviewed the proposed design for the window wall and recommended ways to improve the selected system’s performance

• Developed details to integrate the window walls with other enclosure systems

• Helped evaluate value engineering proposals and alternates submitted by the construction team

• Reviewed shop drawings to compare with the design intent

• Visited the site to observe ongoing construction and helped the contractor resolve field conditions

• Observed water and air infiltration testing of the window to compare with the specified performance requirements
