Mr. Sanjeev Sharma Z Realty Plus Plan Check Number: B2006-012, First Building Review August 28, 2020 8. Detail 07/A9.01 shows the connection of the posts to the structure. The details for the guards and connections are not complete and should be revised. Half of the lag screws do not appear to connect to framing. Calculations should be submitted for review substantiating the design of the guards, connections, and supporting framing. The loads per IBC Section 1607.8.1 should be used. See IBC Sections 1603.1 and 1604.1. Structural General: 1. Structural and geotechnical special inspections appear to be required for this project. Inspections include but are not limited to preparation of bearing soils, concrete construction, and shear wall nailing. The drawings should include a table listing each type of special inspection and the extent of each inspection (e.g., continuous, periodic) per IBC Section 1704.3.1. The table should include special requirements for seismic and wind resisting systems as required by IBC Sections 1704.3.2 and 1704.3.3, respectively. See IBC Sections 107.1, 1704.2.3 and 1704.3. 2. Concrete Note 13 in the General Structural Notes on Sheet S3 specifies concrete strengths less than 4,500 psi. The project appears to include concrete elements that are exposed to freeze - thaw cycles and water and qualify as Class F2 concrete per ACI 318-14 Table 19.3.1.1. Per ACI 318-14 Table 19.3.2.1, the minimum concrete strength for Class F2 concrete is 4,500 psi. The minimum concrete strength should be revised. See IBC Section 1901.2. 3. The roof trusses are a manufactured system designed by a fabricator. The General Structural Notes should include a note specifying the trusses as a deferred submittal. The notes should state the FOR for the project should review the truss design for conformance with the construction drawings and approve the shop drawings prior to fabrication of the trusses. The note should reference the roof plans for additional in -plane loading for trusses transferring diaphragm loads to the Upper Floor shear walls. See IBC Sections 107.2.1, 107.3.4.1, and 1603.1.8. Foundations: 4. The foundation details on Sheet S1 specify a 6-inch clearance between the wood framing and finished grade. The wall framing and sheathing are required to be naturally -durable or preservative treated wood unless a minimum clearance of 8 inches is provided. Floor framing and sheathing in Detail Ai/S1 must be similarly use decay -resistant wood materials. The details should be revised. See IBC Section 2304.12.1.2. 5. Calculations substantiating the design of the foundations are not provided and should be submitted for review. The calculations should include the evaluation of the soil bearing pressures. See IBC Sections 1604.1 and 1604.2. Q3200 Cedar Street © 425.257.8810 everetteps@everettwa.gov Everett, WA 98201 425.257.8857 fax everettwa.gov/permits Page 3 of 5
