GENERAL NOTES:
1.Design is in accordance with the Florida Building Code 6th Edition (2017)
for use within and outside the High Velocity Hurricane Zone (HVHZ).
2.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 structure (if any) is assumed to be in good condition,
capable of supporting the loaded system. No warranty, either expressed
or implied, is contained herein.
4.System components shall be as noted herein. All references to named
components and installation shall conform to manufacturer's or industry
specifications as summarized herein.
5.Where site conditions deviate from those noted herein, revisions may be
required or a separate site-specific engineering evaluation performed.
6.Aluminum components in contact with steel or embedded in concrete
shall be protected as prescribed in the 2015 Aluminum Design Manual,
Part 1. Steel components in contact with, but not encased in, concrete
shall be coated, painted, or otherwise protected against corrosion.
7.Engineer seal affixed hereto validates structural design as shown only.
Use of this specification by contractor, et. Al, indemnifies and saves
harmless this engineer for all costs & damages including legal fees &
apellate fees resulting from deviation from this design.
