STRUCTURAL ENGINEER’S REPORT
On May 24, 2021, Mr. William Norman, PE, SE, of the consulting engineering firm of
Keeler-Webb Associates conducted an inspection of the above reference property for
structural concerns regarding modified roof truss framing.
The subject residence is a two story wood framed structure that has been framed using
pre-engineered metal-plate-connected roof trusses. The trusses over the garage had
been modified and with 2x10 lumber installed spanning side-to-side of the garage in
order to construct a bonus closet space over the garage.
Due to the large span (~20 ft.) and the spacing of the joists (24” apart) the floor joists
were deflecting (sagging) closely 1” and will continue to deflect further over time. The
added floor framing is simply inadequate for the span and spacing.
Our recommendation would be to install two beams below the floor framing, and in line
with the side walls of the closet, perpendicular to the 2x10 floor joists. These beams
could be hung upon the beams that are at the garage header and also near the mid-wall
of the home. The garage header is likely at the garage door level and therefore the new
beams can likely be placed on top of this header once the drywall is removed.
We would estimate the engineering for the beams and to assure that the other beams
are adequate (this will require drywall removal to measure the beam sizes) will be in the
range of $500. We suspect that the existing beams are adequate to support the two
new beams but again, further evaluation would be recommended.

The two new 17.5 ft. long beams are estimated to be either 3-1/2” x 12” or 5-1/4” x 9-
1/2” LVL’s, but they might also be as small as 3-1/2” x 9-/14” (calculations to determine
the beam size have not been completed).
The opinions stated in this report are based upon the physical evidence present at the
time of our inspection as attested to by the digital images submitted herewith, and also
retained in our file.
Unless additional detail, assistance, or other engineering effort is requested, this
investigation is considered to be complete and sufficient as per the scope of
engineering work required and no further technical support will be provided.
