Wind loads have been calculated per the requirements of ASCE 7-10 as
shown herein.
3.
These engineering calculations pertain only to the structural integrity of
those systems, components, and/or other construction explicitly specified
herein and/or in accompanying engineering drawings. The existing host
Index:
structure (if any) must be capable of supporting the loaded system as
