RE: Framing Review 1
Mr. McKittrick & Ms. Ahlstrom,
As requested, ERS Consulting Engineers (ERS) has reviewed the following items regarding structural
framing completed to date. The purpose of this review was to confirm general conformance with the
construction documents, and to address any conditions that may not have been constructed as specified
in the approved permit drawings. Deviations or clarifications from the approved permit drawings are
summarized as follows:
Main Level:
1. In the garage, the Upper Level Framing Plan (A2/S-1.4) specifies Simpson CCOQ7-SDS2.5 beam
saddles at the interior steel columns. These saddles were substituted with a shop fabricated
saddle similar to the specified product.
ERS has reviewed this condition and found that the saddle, as fabricated and installed, is an
acceptable alternative.
2. At the laundry room, the Upper Level Framing Plan (A2/S-1.4) specifies 11 7/8” TJI 210 floor
joists between Grid G & J, spanning from Grid 8 to Grid 5. This area was framed with 7 ¼” LVL.
@ 16” o.c.
ERS has reviewed this condition and found that the 7 ¼” LVL joists are an adequate substitution.
3. In the Great Room / Dining area (north wall), the Roof Framing Plan (A4/S-1.2) specifies (3)-5
½” LVL columns between the windows, extending vertically to support the glu-lam beams
above. (2)-2x10 headers are specified over the windows and between these columns, but
support for the headers is not specified. The headers have been substituted with LVL material
and a single 1” jack stud is provided to support the headers.

ERS has reviewed this condition with the contractor. These headers carry minimal load,
therefore the single 1” jack studs are adequate. ERS has also reviewed the framing conditions
surrounding the glu-lam beam support and found the as-built conditions to be acceptable.
This concludes our review of structural framing concerns. If you have any questions, or would like to
discuss any of the conditions noted herein, please contact our office.
