These charts are sold as engineered sealed documents and meet the requirements of the selected Florida Building Code using “ASD METHOD” ASCE 7-10 for the determination of wind pressures acting upon mechanical equipment using either the “At-Grade Sign” method or “Rooftop Structures” method (rooftop structures method per FBC 1609.8). The selected FBC allows a permit applicant to submit for a mechanical equipment installation using the submission of one of these sealed wind pressure charts.


For FBC 6th Edition (2017)

For residential structures (“Risk Category II”) in Broward and Palm Beach Counties, the required wind velocity is 170mph.


For residential structures (“Risk Category II”) in Miami-Dade County, the required wind velocity is 175mph.


If you are near the coast, it’s Exposure ‘D’; inland is Exposure ‘C’.


Additional wind velocity requirements can be verified by calling your local Building Department.
