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 onlyto 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, subject to building department
approval. 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.
required or a separate site -specific engineering evaluation
6. Aluminum components in contact with steel or embedded in concrete
shallbeprotected as prescribed in the 2015 Aluminum Design Manual,
Part 1. Steel components in contact with,lbut 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 engineerfor all costs & damages including legal fees &
