About this file
This document is an architectural drawing (Sheet AB200) detailing translucent wall panel specifications for a boathouse project, specifically for a Coast Guard facility at Base Seattle. The specifications outline precise technical requirements for the translucent wall panels, including performance standards such as light transmission, weather resistance, and material properties. Key technical details include:
Panel specifications mandate a sheet thickness of 0.06 inches, flexural strength of 13,500 pounds per square inch, and rigorous performance criteria over a 10-year period. The panels must maintain less than 10% light transmission change, minimal yellowing, and meet specific fire safety standards (ASTM E84 flame spread < 25, smoke developed < 450). Structural requirements include using stainless steel self-tapping fasteners with seal washers, and installation must conform to manufacturer instructions and design wind pressure specifications referenced on structural sheet SB001. The drawings show multiple elevations of a boathouse structure, including west, north, south, and east views, indicating a comprehensive architectural plan for the facility.
