Permit No. 0
We have determined, based on worst —case conditions, the minimum number of concrete screw
anchors required to withstand theshear, force applied to the wood buck for all windows and
doors for the above referenced project.
The force has been determined for each side of each window/door based on ASCE 7-10 with
170 MPH Vult, EXPOSURE D ENCLOSED, 30' MEAN HEIGHT, 5:12 PITCH, with Kd=0.85
using the ALLOWABLE STRESS DESIGN method. These values are representative of the
minimum tributary area (10-sgft); the actual wind pressure for any component larger the 10-sgft
would be less.
t
The shear tolerance for the anchors is based on 1/4"x3" TapCons (or equal) with a minimum one -
inch (1 ") embedment into medium weight hollow block with a factor of safety of 4:1 (25%
ultimate load values). Further load reductions have applied for less than nominal spacing and
edge distance, in accordance with manufacturer recommendations.
I do hereby certify that:
• The fasteners used for the installation of all windows and doors for the above referenced
project meet or exceed our requirements (as described above).
• The number of fasteners used to secure all exterior windows and doors for the above
referenced project meets or exceeds our calculated requirement for the buck
attachment.
• The attachment of the wood buck to the masonry via concrete screw anchor through the
associated window frame,and into the masonry, in conjunction with our preceding
certifications, is in accordance with FBC 2017 requirements:
The following pages contain an accounting of all installed windows and doors, with the
calculated wind force and fastener requirements. Noted on each is the actual number of
fasteners installed. If you have any questions please do not hesitate to contact me.

THE BUILDING AND SUPPORTING FOUNDATION SYSTEM HAVE BEEN DESIGNED TO
WITHSTAND THE EFFECTS OF WIND AND FLOOD LOADS ACTING SIMULTANEOUSLY ON
STRUCTURAL AND NONSTRUCTURAL BUILDING COMPONENTS. ACKNOWLEDGED. Frangible
walls have been designed in accordance with FBC requirements and ASCE 24 guidelines, in
conjunction with FEMA recommendations. A Note has been added on Sheet S-1 under
GENERAL NOTES #11 & #12.
27) PLEASE CLEARLY IDENTIFY THE LOCATION OFALL FRANGIBLE WALLS AND SLABS ON
THE FOUNDATION PLAN, REQUIRED PER (R322.3.2, R322.3.4, 3109.3.4). ACKNOWLEDGED. All
slabs below the DFE are intended to be frangible; a note has been added to sheet S-3 to reflect
this. Further callouts have been added through the slab plan (sheet S-3). it had been noted on
sheet S-4 (bottom -left) that all masonry walls below the DFE are to be frangible, as well as a
designation for masonry shearwalls; further call -outs have been added to clarify (sheet S-4).
• 28) ELECTRICAL, MECHANICAL AND PLUMBING SYSTEM COMPONENTS ARE NOT TO BE
MOUNTED ON OR PENETRATE THROUGH WALLS THAT ARE DESIGNED TO BREAK AWAY
UNDER FLOOD LOADS. (R322.3.4). Addressed by Architect. Notes regarding MEP components

the FBC, is restricted to the first & second floors. The use of enclosed spaces below the DFE
has been defined on Architectural Sheet A200.
• 30) ENCLOSED AREAS BELOW THE DESIGN FLOOD ELEVATION SHALL BE USED SOLELY FOR
PARKING OF VEHICLES, BUILDING ACCESS OR STORAGE. (R322.3.5). ACKNOWLEDGED.
Habitable space, as defined in the FBC, is restricted to the first & second floors. The use of
enclosed spaces below the DFE has been defined on Architectural Sheet A200.
• 31) ENSURE ELEVATOR CONTROLS SHALL COMPLY WITH (3109.3.4). Addressed by Architect.
Elevator control note added to -Architectural Sheet A200._
32) SEE (R322.3.5.1) PROTECTION OF BUILDING ENVELOPE. AN EXTERIOR DOOR THAT
MEETS THE REQUIREMENTS OF SECTION R609 SHALL BE INSTALLED AT THE TOP OF STAIRS
THAT PROVIDE ACCESS TO THE BUILDING AND THAT ARE ENCLOSED WITH WALLS
DESIGNED TO BREAKAWAY IN ACCORDANCE WITH SECTION R322.3.4. Per discussions with
building officials, it has been determined that the proposed home does not lie in a Coastal A
Zone, and is thus not required to meet the design standards as outlined in section R322.3 of the
FBC.
33)'ENGINEER TO CLARIFY- THE TRUSSES ARE DESIGNED FOR AN ENCLOSEDBUILDING.
THE BUILDING COULD POTENTIALLY BE OPENED IN A WIND/FLOOD EVENT WHEN GROUND
LEVEL WALLS BREAKAWAYCREATING AN OPEN/PARTIALLY ENCLOSED BUILDING.
CLARIFICATION. The house has been designed as an enclosed building, in accordance with
Florida Building Code. The collapse of frangible elements of the building shall not have a
noticeable impact the function of the roof system.
ZONING COMMENTS
31712019 Comment: ELEVATION PAGE REQUIRED TO INDICATE THE LOBBYAREA
AT 14.1'. The FBC allows for enclosed spaces below the base flood elevation, if those areas are
designed in accordance with the ASCE 24 and (for structures east of the Coastal Control Line)
FBC 3109 and FBC R322. The enclosed areas below the base flood elevation are intended to be
used solely for vehicle parking (garage), storage, and building access (lobby). All of these
