Plan Check Number: B1907-001, First Building Review <br /> 1225 E Casino Road, Everett, 98203 <br /> August 7, 2019 <br /> Page 5 <br /> Structural Correction Item #10: <br /> Detail 2/S-2.00 species support of the wood posts on the concrete footings-on-grade,with <br /> direct bearing on a steel column base achorage. While the posts are not in direct contact <br /> with the concrete,they are in close proximity with the concrete and adjacent soil. It is <br /> recommended that Detail 2 specify application of a preservative treatment to the post bases <br /> to prevent deterioration. See IBC Section 2304.12.1.4. <br /> Response to Structural Correction Item #10: <br /> The detail has been updated to specify that a pressured treated (PT) post shall be provided. <br /> The calculations were updated to reflect that the posts will be incised. <br /> Structural Correction Item #11: <br /> The Repair Plan 2/51.00 indicate the presence of an unidentified existing steel beam. <br /> Based on the building construction and a review of City of Everett records,the beam does <br /> not appear to be original construction and was not installed with a building permit. The <br /> purpose of the beam in the gravity load path shall be clarified. If the beam is required to <br /> supplement or replace the existing wood beam, documentation substantiating the beam <br /> design shall be submitted for review. The beam size, length,and position in the floor framing <br /> shall be specified. Details for the connection of the posts to the beam shall be included in <br /> the construction drawings. See IBC Section 107.2.1, 1603.1, 1604.1, and 1604.4. <br /> Response to Structural Correction Item #11: <br /> Based on a site visit made by the engineer of record,the steel beam does not appear to be <br /> integral with the gravity load path.The wood girder the steel beam is adjacent to does not <br /> appear to be damaged or show signs of other defects that may inhibit its structural integrity. <br /> Calculations do not account for any additional capacity from the steel beam; however, as the <br /> beam does not interfere with the proposed work,the intent is to let it remain in place. <br /> Sincerely, KEVIN a <br /> l 4;5 pc WAsy. p <br /> 4 1 c,�' <br /> ac h =t^ <br /> Kolby Burke, PE, SE • g <br /> Vice President ` t <br /> g :44›.C. ,\P3.9 <br /> ,171 <br /> TOWER ENGINEERING COMPANY <br /> 6-/ 5) <br /> 21907 64th Avenue West, Suite 140, Mountlake Terrace, WA 98043-2298 <br />
