Structural Recommendations
January 27, 2021 REVIEWED
BY
Ryan Anderson, PE, SE CITY OF EDMONDS
SSF Engineers completed on -site structural observation of the existing roof framing at 21302 93" PI W. in Edmonds,
Washington. We understand that several interior walls (indicated with dashed lines in the attached partial roof framing
plan) are proposed to be removed as part of the renovation. The existing roof framing consists primarily of
premanufactured roof trusses spanning east -to -west from exterior wall to exterior wall. Where the orientation of the
trusses changes to accommodate the skew in plan the roof is stick framed with rafters and ceiling joists. The rafters frame
into short spanning ridge beams that are supported by full span girder trusses as indicated on the plan. The ceiling joists
in this area appear to splice above the interior walls below.
In these locations, we recommend supporting the existing ceiling joists up to the existing rafter above with a 2x6 each
side of each splice location per SSK-2 (attached). Upon completion of the proposed ceiling joist reinforcing, the interior
walls below may be removed.
All existing framing shall be field verified by the contractor prior to demolition. The contractor shall notify the structural
engineer if existing conditions determined during work vary from the existing construction shown on the drawing.
