STRUCTURAL OBSERVATION REPORT
Project: 325 Walnut Remodel
Purpose: Structural Evaluation
Location: 325 Walnut St, Edmonds, WA 98020
Date: January 2"d, 2017
CG Project:
Report: 1
Client: Chermak Construction
General Contractor: Chermak Construction
Field Rep: Dennis Titus, PE, SE; Michaela Burr, EIT
PURPOSE AND SCOPE
Field representatives of CG Engineering were on site on January 2, 2017 to evaluate problems with
the framing that were discovered upon the removal of a bathroom ceiling and walls.
EXISTING BUILDING
The existing building is a three-story wood framed condo building comprised of multiple units. The
condo unit is on the south side of the second story. At the time of the site visit, the wall board and
ceiling had been removed, allowing the framing to be observed.
OBSERVATIONS & RECOMMENDATIONS
Cracked Top Plate — The existing top plate located in the west wall of the bathroom has a large
crack perpendicular to the grain and has shifted approximately % inch from its original position.
The top plate has three openings where pipe travels through it. The pipes are from the original
construction as well as a previous remodel in the condo above. We recommend installing a 24
inch by 1-% inch by % inch plate recessed into the existing top plate shown in the attached
drawing. It is acceptable to recess the plate into the existing top plate. We recommend using
inch diameter Simpson SDS Screws with 2- % inch penetration placed at 3 inches on center.
2. Notched End Joist — The end joist on the north side of the bathroom has two large cutouts to
allow for pipes to travel within the ceiling framing. The observed notches take up a large
portion of the depth of the joists. We recommend installing new Simpson A35 supports on each
side of each notch to stabilize the existing joist shown in the attached drawing.
Portion of Newer Framing_— Ap newer portion of framing observed is connected with screws
and does not have any hangers supporting the joists. One joist does not span to the top plate
and is connected to an older portion of joist with screws. For this joist, we recommend that a
new 2x10 is sistered to the existing short joist which will bear on the existing top plate.
Additionally, we recommend the addition of new Simpson HU26 hangers to this portion of
framing. These changes are shown in the attached drawing.
4. Cracked Joist — The existing joist shows damage at the hanger as well as a large parallel to grain
crack near the hanger. Due to the damage observed, we recommend replacing the existing joist
hanger with a new Simpson LU28 joist hanger shown in the attached drawing.
