Re: Mullins, Metal Building Re -Skin
Enterprise Road, Ft. Pierce
To Whom It May Concern:
C
It is my understanding the existing building is a Pre -Engineered metal building approximately 60'
by 100' in plan with a 20' eave height. The proposed scope of work involves replacement of the
roof and wall panels. The proposed wall panels are Super Span 24 gauge steel wall panels as
manufactured by Whirlwind Building Systems as listed in Miami -Dade NOA 02-0222.12. The
proposed roof panels are Super Span 24 gauge steel roof panels as manufactured by Whirlwind
Building Systems as listed in Miami -Dade NOA 02-0222.13. Fasteners are #12-14x1'/4" TEK
screws with 0.58" O.D. seal washers and are located both sides of deck ribs at end and panel
laps and at one side of deck ribs at typical supports.
The wind design parameters per the Florida Building Code 2001 edition for the building are as
follows: wind speed 140 mph; importance factor 1=1.0, exposure category'B', enclosed building,
enhanced perimeter zone width a = 6.0 feet. The design pressures are listed below:

Note: All pressures listed are in pounds per square foot (PSF)
I have reviewed the NOA's for both wall and roof panels for compliance with the building design
pressures and the proposed wall and roof panels are adequate with the following limitations:
Installation shall be in strict compliance with the Miami -Dade NOA. The maximum spacing of
the roof purlins in the edge and ridge zones (zone 2) shall be 4'-3". The maximum spacing of
the roof purlins in the corner zone (zone 3) shall be 3'-6"
I trust this provides you with the information you require. If you need additional information or
have any questions please contact this office.
