• • <br /> Mr. Kurt Nelson <br /> Rice Fergus Miller <br /> Plan Check Number: B2001-027, First Building Review <br /> February 7, 2020 <br /> Structural <br /> General: <br /> 1. Structural and geotechnical special inspections are required for this project. A statement on <br /> special inspections is provided in the"Special Inspection" section of the General Structural <br /> Notes on Sheet S00.01. The statement shall include a table listing each type of special <br /> inspection and shall specify the extent of each inspection (e.g., continuous, periodic) per IBC <br /> Section 1704.3.1. The table shall include special requirements for seismic and wind resisting <br /> systems as required by IBC Sections 1704.3.2 and 1704.3.3, respectively. See IBC <br /> Sections 107.1, 1704.2.3 and 1704.3. <br /> 2. The structural drawings include a "Deferred Submittals"section in the General Structural Notes <br /> on Sheet S00.01. The section appears to list work that is not included in the project, including <br /> but not limited to: post-tensioned concrete, pre-fabricated wood and steel trusses and joists, <br /> and stair systems. The list should be revised to remove work that is not in the project scope. <br /> See IBC Sections 107.2.1, 107.3.4, 107.3.4.1, and 107.4. <br /> 3. The structural drawings include a "Deferred Submittals"section in the General Structural Notes <br /> on Sheet S00.01. The list should be revised to include the elevator system. Additional <br /> comments regarding the elevator design are provided below. See IBC Sections 107.2.1, <br /> 107.3.4, 107.3.4.1, and 107.4. <br /> Foundation System: <br /> 4. The Foundation Plan on Sheet S21.01 includes construction of an elevator pit adjacent to an <br /> existing load bearing foundation wall. Section 12/S40.02 indicates that the excavation for the <br /> pit will be below and potentially undermine the existing wall footing. The following comment <br /> should be addressed: <br /> a. Underpinning of the existing wall should be provided. Documentation substantiating the <br /> underpinning design should be submitted for review. See IBC Sections 1803.5.7 and <br /> 1804.2. <br /> b. Movement monitoring of the existing wall should be performed. The requirement should be <br /> specified in the"Structural Observation"section of the General Structural Notes on Sheet <br /> S00.01. See IBC Sections 1803.5.7 and 1804.1. <br /> 5. The Foundation Plan on Sheet S21.01 includes construction of an elevator pit adjacent to an <br /> existing load bearing foundation wall. The proposed construction along the existing wall is <br /> shown in Section 12/S40.02. See IBC Sections 107.2.1 and 1603.1. The following comments <br /> should be addressed: <br /> a. The existing wall is presumed to include a footing on each side, as appears to be shown in <br /> the plan. Section 12 does not show the footing. The intent of the design appears to <br /> include demolition of the footing. The design intent shall be clarified and the section revised <br /> as needed. See IBC Section 107.2.1. <br /> 0 3200 Cedar Street 0 425.257.8810 A.01 everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 5 of <br />
