t • f ' <br /> BCIE Job No. 16010 -2- February 19,2016 <br /> FINDINGS: <br /> 1. The building's breezeway construction consists of an unknown membrane over 3/4" plywood <br /> (PWD) floor sheathing and 2"x10" floor joists spaced at approximately 16" on center (oc),with <br /> double 2"x10" beams at the landings and 1/2" gypsum ceiling board (GCB), covered by vinyl <br /> siding for the soffits. The breezeway's exterior bearing wall construction consists of double- <br /> sided vinyl siding over building paper, 5/8" PWD siding/sheathing and 1/2" gypsum wallboard <br /> (GWB), with 2"x4" studs at approximately 16" oc. The length of the breezeway wall is <br /> approximately 13'-6" and meets the breezeway where it changes to a north/south orientation for <br /> the other units at the north side of the building. No additional construction as-built verification <br /> was completed as it was not pertinent to BCIE's investigation. <br /> 2. BCIE found a vehicle struck the west end of the breezeway's exterior wall at a slight southeast <br /> angle,causing damage to the end 2'-6" of the wall,pushing it to the south and east. <br /> Temporary shoring had been installed by the property maintenance staff to support the landing <br /> beam supported by the breezeway exterior wall. The damage for the breezeway exterior wall <br /> included full-height studs that extended beyond the landing to the height of the second floor <br /> units. There was no visible damage to the breezeway landing. <br /> BCIE also found damage to an exterior elevated walkway accessed from the main floor of the <br /> breezeway at an opening to the east of the vehicle impact location that is used to access the <br /> maintenance storage unit for the complex. The construction of the elevated walkway consisted <br /> of a similar membrane and PWD sheathing, with 2"x10" joists and guardrails consisting of a <br /> 2"x4" top plate, 1"x and 2"x trim, 2"x2" pickets and 4"x4" guardrail posts at a maximum of 6' <br /> oc. The damage to the elevated walkway was isolated to the guardrails only and due to the <br /> deficient spacing of the pickets allowing for an object of larger than 4" to pass through, the <br /> entire length of guardrail for this section will need to be demolished and rebuilt to meet current <br /> code requirements. <br /> OPINIONS: <br /> Based on an analysis of our findings, it is BCIE's opinion the vehicle impact resulted in moderate <br /> isolated damage to the west end of the breezeway's exterior wall and the guardrail system for the <br /> elevated walkway at the north side of the breezeway. The approximate 2'-6" length of the <br /> breezeway exterior wall was damaged and will need to be removed and replaced, with new <br /> construction to match original and meeting current code requirements. The new guardrail will need <br /> to meet current code requirements, including a maximum 4" object being able to pass through the <br /> guardrail system. The repairs will require a permit be submitted to the local jurisdiction,which is the <br /> City of Everett and prior to this damage assessment report, BCIE completed the repair plans and <br /> submitted them to the property management company. <br /> RECOMMENDATIONS: <br /> BCIE recommends the repairs be completed per the repair plans submitted by BCIE prior to <br /> completion of this report and the property management's contractor will need to submit the repair <br /> plans to the City of Everett for review,approval and issue of the repair permit. <br /> a� <br />
