Date: August 3, 2021
Project: Bruhn Door/Window Replacement
Address: 9550 S Ocean Drive, #305, Jensen Beach, FL 34957
Dear: St Lucie County Building Official(s),
I (James Drago, Registered Architect) have conducted a review of the proposed
design pressures (PSF) for the above Commercial Property location to replace the
doors and windows shown on the attached Floor Plan.
Above 30' component height are as follows:
(See attached Floor Plan for specific door and window size and design pressures)
• ZONE 4-51.4/-67.5
• ZONE 5-51.4/-123.6
• Zone 5 is defined as 8.o' of building wall from building corners.
• Zone 4 is defined as all other wall space.
Design pressures calculated with
• II
occupancy category
• 16o
mph ultimate design wind speed
• D
asce exposure category
• 1
wind directionally factor (Kd)
• 1
topographical factor (Kzt)
• 8o'
min. (least) building dimension
• 18o'
mean roof height, mrh
• 26'
elevation of installation
• Flat (<io
deg) roof slope
Therefore, please accept this letter as a formal certification that to the best of my
belief and professional judgment that the proposed design pressures (PSF) to
replace the doors and windows inst llation will meet (or exceed) the minimum
requirements set forth by the 2 20 Florida Building Code — Building, 7th Edition.
Thank you in advance for y r s istance in this matter.
