`_ civil&structural ® ENGINEERING engineering&planning STRUCTURAL OBSERVATION REPORT Project: Craig Wood Purpose: Structural Evaluation Location: 8618 Xavier Way, Everett,WA 98208 Date: February 26th,2018 CG Project: 18065.10 Report: 1 Client:Craig Wood General Contractor: N/A Field Rep: Stephen Tabert, EIT PURPOSE AND SCOPE A field representative of CG Engineering was on site on February 22,2018 to evaluate whether a wood stud wall that had been removed was load bearing or not. While on site,the client discussed adding a new window, lengthening an existing window, and infilling an existing bay window on the west exterior wall of the house. EXISTING BUILDING The existing building is a one-story,wood framed,single family residence constructed in 1994. The roof is a gable end roof framed with premanufactured wood trusses. The floor is framed with lumber joists supported on post and beam framing in the crawl space. The foundation is a conventional spread footing foundation. See Photo 1 for an aerial image of the project site. OBSERVATIONS& RECOMMENDATIONS 1. Removed Wood Stud Wall—Photos 2 and 3 show the location of the removed wall. The outline of where the wall used to be can be seen on the subfloor and at the ceiling/wall finishes. It was determined in the field that the removed wall was not a load bearing wall. The roof was framed with trusses spanning from exterior wall to exterior wall. See Photos 4, 5 and 6 for the truss framing. 2. Window Revisions on the West Exterior Wall—While on site,the client discussed infilling an existing bay window as shown in Photo 7, lengthening an existing window from 4'-0"to 5'-0" in the kitchen and adding a new 4'-0" long window in the bathroom. The bay window to be infilled is 7'-4" and the total length of new window openings is 5'-0". Since the infilled wall length is larger than the proposed openings in the west wall, no further analysis of the west exterior shear walls is required. The infilled wall shall have%2" plywood or OSB sheathing with 0.131"diameter x 2-1/2" long nails at 6" OC at the panel edges and at 12" OC in the field. Provide 0.131" diameter x 3-1/4" long nails at 6" OC from the sill plate to the rim/blocking below. Provide Simpson LTP4 clips at 24" OC from the rim joist/blocking to the sill plate. For the new window headers, provide 4x8 HF#2 beams with a max span of 5'-0". Provide (1)cripple and (1)full height HF stud each end of the header. 250 4th Avenue South,Suite 200 Edmonds,WA 98020 ph.425.778.8500 I f.425.778.5536 www.cgengineering.com
