Re:
1607-03 Viola Remodel
Dear Mr. Elicker,
You requested that KRM REVIEW a remodel project at 795 Potato Patch Drive in Vail CO. The
project includes converting a portion of the existing crawl space to a new bedroom which will
require an existing crawl space wall vent to be converted into an egress window. You requested
that KRM provide a header size as well as a retaining wall design for an area under the existing
deck that needs to have a lower grade to provide sufficient room for the new egress window.
We visited the site on 6/30/2016 and reviewed the following drawings to prepare the requested
design details:
DRB ARCH DRAWINGS dated 5-18-16 from Martin Manley Architects
KOENIG Residence structural drawing dated 3-21-95 from Monroe and Newell
The design loads used to evaluate the existing structure and design the new structural elements
are as follows:
Roof Snow Load: 80 PSF
Roof Deal Load: 15 PSF
Floor Live Load: 40 PSF
Floor Dead Load: 15PSF
Deck Live Load: 100 PSF
Deck Dead Load: 15 PSF
Lateral Earth pressure fluid Equivalent: 50pcf
Based on our site visit and the above drawings it is acceptable to use the following header for the
new egress window in the lower level: (3)—9 %z LVL with(2)-2x6 jack studs and (1)-2x6 king •
stud per side. If during demolition of the existing structure you find anything that differs from
the original structural drawing please notify us to reevaluate the design.

For the retaining wall under the existing deck please see the attached sketch for a cross section of
the proposed wall. The estimated values that were used in the design should be confirmed by a
geotechnical engineer during construction and any variance should be reported to us for
evaluation.
The above design recommendations are based on a review of the above listed drawing and the
visual inspection of the property. Any variations from the original drawings or changes to the
architectural drawings should be reported to the Engineer for review and evaluation. •
