Dear Plans Examiner,
The site -beam, which was installed by Palm Harbor Homes, and is approved by HUD,
Manufactured Home Construction & Safety Standards, is constructed to receive on -site
additions that are built and designed by others to accommodate such amenities as
carports, sheds, and screen rooms. The on -site structure must be designed by a Florida,
registered, engineer, to the Florida Building Code and all local codes. This plant -
installed site beam is of adequate design for this purpose as long as tie downs and pierigg
are per page 1 of Section 11, Misc. & Final Inspection section of the installation manual
(attached). The attached details, EW-216.2 and PA69-EW-31, are approved by the
Manufactured Home Construction & Safety Standards. And, the design loads for the
plant -installed site beam, as well as the supporting structure and anchorage are from the
FBC and ASCE 7.
I can be of further assistance at the above contact information.
Sincerely yours,
Bruce Bussell
Engineering Manager

SECTION 11—MISCEI-I-kNEOUS AND FINAI.INSPECTIONS IndeX
11.1. AWNING, CARPORTS, PORCHES, UTILrff ROOMS, ETC.
Additional shuCtures such as awnings, carports, patio covers or attachments to a Palm
Harbor Home have not typically been taken into consideration nor calculated into the
design for roof or wind loads. Any additions made to the home must be self-supporting
and shall not interfere with weatherproofing (i.e. shingles, flashing, gutters, siding).
However, some Palm Harbor homes have an option to be ordered with a factory installed
receiver designed to take the loads of an add -on. In this case, refer to the detail for
information on specific construction and requirements.

2. The factory installed receiver is designed to handle the additional uplift and downward loads
from the connection of the awning to the main unit
3. The awning roof and roof support away from the main unit must be designed (by others) to
tarty all loads to the ground. The design of the awning connection along with weatherization
(by others) must be designed to carry the appropriate load into the factory -installed r=ivcL
The design must be according to the loads and requirements of the ARC 2003 for exposure V.
4. Factory installed members were designed for awning loads based on 90 mph (3 second gust)
winds for wind zone 1, 120 mph (3 sec. gust) winds for wind zone 2, and 140 mph (3 see.
gust) winds for wind zone 3. This is in accordance with ARC 2003, exposure'c'.
