RE: Foundation/Stemwall-Proposed carport enclosure-(RES Job#10-018)
RES Engineering made on-site observations of the concrete stemwall(s)placed on top of the existing
concrete floor of the original carport structure addressed in our letter of June 17,2010. Based on these
observations we have determined that the as-built construction is adequate to support the normal design
out-of-plane lateral loading induced as a result of enclosing the carport structure. The in-plane lateral
and vertical load path is unaffected by the added stemwall.
We have also reviewed the drawings you provided which show the original framing which consisted of
4x4 posts at(nominally)4'oc on the sides walls and 4x4 posts at(nominally)T oc at midspan of the roof
framing with beams supporting the roof structure. There was no post at the front of the carport. The
plans reviewed denote the original framing members as"existing". The drawings are adequate to rebuild
the carport as originally framed.
Please be advised that the carport structure needs to be supported as it was originally in order to insure
that the loading to the existing foundation,and to the exterior wall between the carport and residence is
not greater than they are capable of supporting.
If you have any questions or other issues,please let us know.
Sincerely, fr

The building plans submitted and approved for building permit number BLD2010-00493 contain limited
information concerning the construction of a garage. The plans were approved based upon existing
conditions including posts and supporting girders that would remain. During the inspection performed on
Friday, August 20, 2010 1 found that all existing elements of the carport have been removed and that you
plan to replace the structure with new framing elements. When a structure is removed all new elements
must comply with current code. The original permit was approved under the 2006 edition of the building
code.
Within the approved plans I find that the floor plan depicted on the same page as the front elevation does
not show all information including an accurate layout for walls. The cross section depicted on the plans
identify existing elements that have been removed and does not identify all required framing elements
including plate and anchor bolt connections. It is unclear how you plan to construct the garage that will
replace the old carport. Please provide a corrected floor plan and cross-section.
It may be possible to approve the new structure prescriptively if the building will be constructed using
conventional methods. I will be happy to work with you on that if you wish. I will need the corrected plans
in order to evaluate. If you plan to use posts please verify that the structure meets prescriptive code
requirements or provide a lateral design in accordance to the 2006 edition of the building code. Since the
foundation is existing and modifications have been made to the existing foundation system the engineer
of record or a new engineer will need to approve the system.
