Lessons Learned
U00266  Bird Nests
Make sure building is cleared of any nesting birds prior to installation
U103640  Panel Layout
Panel layout required more than necessary custom panels
Design as many standard panels as possible
U103640  Panel Tolerance
Panel tolerance was tighter then tolerance for structural steel
Match tolerances of product manufactured
