Mr. Nathan Crawford <br /> Plan Check Number: B1907-025, First Structural Review <br /> August 6, 2019 <br /> Structural <br /> General: <br /> 1. The proposed project shall comply with the requirements of the 2015 International Building <br /> Code. The code shall be specified in the construction drawings. See the Everett Municipal Code <br /> Section 16.005.030 Article A and IBC Section 101.4.7. <br /> 2. The structural drawings do not include structural notes. The drawings should specify design <br /> loads, geotechnical criteria, material properties, special inspection requirements, deferred <br /> submittal requirements, and other information pertinent to the structural design per IBC Section <br /> 1603.1. Geotechnical information, including but not limited to the design soil bearing pressure, <br /> should be specified per IBC Section 1603.1.6. See additional comments below addressing <br /> specific requirements. <br /> 3. The structural notes shall specify the allowable soil bearing pressure for the foundations. The <br /> project does not appear to include a geotechnical investigation of the project site soils. The <br /> . bearing presssure shall not exceed the presumptive value of 1,500 psf per IBC Table 1806.2 for <br /> Class 5 materials. See IBC Section 1603.1.6. <br /> 4. The construction drawings do not include material requirements for the structural framing. <br /> Material properties, connection requirements, fabrication and coating requirements, and other <br /> information required to perform the structural work shall be specified in accordance with the <br /> following design standards: <br /> a. Concrete (includes reinforcement): IBC Sections 1901.5. <br /> b. Steel: IBC Section 2205.1, AISC 360-10 Section A4, and AISC 303-10 Section 3.1. <br /> c. Wood: IBC Section 2306.1 (ASD) or 2307.1 (LRFD), and NDS-15 and AWC SDPWS-15. <br /> 5. The proposed design will develop lateral loads due to wind and earthquake loading that must <br /> be resisted by the main structure. The structural notes shall specify the wind and earthquake <br /> design data for the project. See IBC Sections 1603.1.4 and 1603.1.5. <br /> 6. The project includes custom steel brackets per Sheet 5 and 6. Special inspection shall be <br /> performed for the fabrication of the bracket per IBC Section 1705.2.1 and ISC 360-10 Chapter <br /> N. Special inspections are required to be performed by the fabricators unless they are, <br /> registered and approved to perform work without special inspections. The structural notes <br /> shall require special inspection to be performed for the steel fabrication, or shall require the <br /> fabricator to be certified to perform special inspection. See IBC Sections 1704.2.5, 1704.2.5.1, <br /> and Section 1704.5 Items 1 and 2. <br /> 7. The project appears to include proprietary hardware (e.g., framing connections, post-installed <br /> anchors, etc.). See Sheet 8 for an example. The construction drawings shall specify the make <br /> and model for each type of proprietary component in the project. Fastening requirements (e.g., <br /> nail sizes and count, etc.) shall be specified for each component where applicable. See IBC <br /> Sections 107.2.1 and 1604.1. <br /> 9 3200 Cedar Street 0 425.257.8810 � ,� everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 2 of 5 <br />
