• 78aUED MAR 22 2024 CITY OF EVERETT L K E V I E W o_ March12, 2024 Permit Services STRUCTURAL -- Ismail Mohammad ENGINEERING PO Box 1094 Woodinville, WA 98072 Sent via: Email Subject: 3516 Rockefeller Ave Residence Remodel and restoration Dear Ismail, On Friday, February 9, I inspected the Rockefeller Ave residence with you and your contractor. At the time of the inspection the lower level of the house had been mostly demolished with the all of the wall framing exposed and some of the flooring. The house is 24 feet wide and 32 feet long. A bearing wall runs the length of the house with post and pier foundation directly under the bearing wall. The floor is constructed of 4x4 joists spaced 36" on center. 4x6 support beams split the span of the 4x4's mid way between the interior bearing wall and the exterior walls. The subfloor was constructed of wood plank spanning over the 4x4 joists. The below grade exterior walls are constructed of 8"x8"x16" CMU sitting on a 16"x6"thick concrete footing. The 4x4 joists are supported on posts at the exterior walls. Both the concrete footing and the block wall appear to be in good condition with no signs of significant deflections or cracks. The 2nd floor is constructed of 2x8 joists spaced 16" on center that span from the exterior walls to the interior bearing wall. The joists appear to be in good condition. Based on my inspection and our conversation on site, I recommend the following items be addressed: 1. The southeast corner has rotted out and must be re-framed. 2. Re-frame the lower level floor with the following: a. 2x8 DFL2 joists @ 16" o.c. b. 4x8 DFL2 support beam running under the center bearing wall c. Support the 4x8 beam with 4x4 posts at 48"max on center. Provide 24"x24"x8"thick pier footings at each post. d. Connect posts to footing with Simpson A35 angles, or equivalent. Anchor to concrete w/ Titen HD screws or other concrete screws. e. Concrete piers should have#4 reinforcement at 12" on center, each way, centered in the footing. 3. At the exterior walls, remove the old joist support posts and provide a new 4x8 beam running parallel to the walls to support the new floor joists. The beam should be supported every 6 feet with a 4x4 post down to the existing exterior wall concrete footing. 4. The exterior wall top plate was constructed with a continuous 6x6 beam. This existing beam is OK for clear spans up to 4 feet. Where the 6x6 has been notched for plumbing, the gaps must be strapped across to resist wind chord forces. 03/12/24 7:43 PM i �
