RE: Addition of Second Story to Residence Located at
1940 County Road 6
Orono, MN
Dear Judith:
As requested, I visited the residence identified above on June 11, 2007, and examined the
building in order to determine if the existing 2x4 stud wall and foundation will support a
new second story for the residence identified above.
Our design follows the requirements of the Minnesota State Building Code and the
International Residential Code, 2000 edition. This includes a floor live load of 40 psf, a
floor dead load of 15 psf, a roof snow load of 35 psf, a roof dead load of 20 psf, a soil
bearing pressure of 45 psf/ft of depth, and an assumed allowable soil bearing of 2000 psf.
The existing stud wall consists of 2x4 construction grade studs at 16" o.c. The stud wall
can support a new second floor with a maximum clear span of 24'-0" and a roof system
with a maximum span of 24'-0". Any point loads from girders, headers, etc have not
been analyzed and must be designed by others.
The existing foundation wall consists of 12" un-grouted masonry with a height of 7'-2".
The existing foundation can support the vertical and horizontal loads noted above
provided a new steel angle is installed at the top of the foundation wall as shown on the
enclosed details on pages 3 — 4 of 4 of this report. The exterior grade must also be
changed so that the grade slopes away from the residence and is not within 12" of the top
of the foundation.
The footing required to support the existing main floor, the new second floor, and a roof
system is 16" wide. Common construction practice is to use a minimum 16" wide
footing, therefore it is my opinion that the existing footing, although not visible, is
adequate to support the loads noted above.
Our involvement in the design of this structure is limited�to the individual members
addressed and specified in this report. All other engineering and design remains the
responsibility of others.
If you require any further information please contact me.
Sincerely,
TIBBITS ENGINEERING, P.A. I hereby certify that this plan, specificarion, or
report was prepazed by me or under my direct
� supervision and that I am a duly Licensed
Professional Engineet under the laws of the State
of Minnesota.
