Drew Martin From: Drew Martin Sent: Tuesday, August 1, 2023 4:21 PM To: Chuck Dougherty Subject: City of Everett Permit Services: 1517 132nd Street SE (B2306-002) - First Building Review Hello, Chuck This email follows our telephone conversation. We have completed the first review of the building plans for this project. As discussed, review the comments below with the design team and let's talk again once you have input from other parties. Depending on the responses to the comments, we may try to redline the drawings or new drawings may be required. I'll provide direction once we receive initial comment responses. Comments Architectural: 1. The south accessible route has a 5.81%slope and qualifies as a ramp. Handrails are required, or the ramp slope should be reduced to not exceed 5%(i.e., 1:20). Note that if handrails are provided, these will require extensions that may conflict with maneuvering at the lower landing. 2. The project is required to provide infrastructure for new and future EV charging stations. See IBC Section 429. 3. The roof is required to be solar-ready per WSEC Section C411. The roof plan should designate a solar area that complies with the fire access clearances per IFC Section 1204.3. The structural design criteria should specify the minimum 4psf superimposed load in addition to other loads;the current 5psf mechanical load should not be considered to include the 4 psf load. Structural: 4. The design of the roof diaphragm, and specifically the tributary loading of the diaphragm to the shear walls, is not clear. Tributary distribution should be based on a flexible diaphragm assumption. It appears that some shear walls may be undersized, including but not limited to Grids H and 6. The direct connection length may not be sufficient for the short walls. Where Additional documentation substantiating the load distribution and diaphragm transfer mechanisms should be submitted for review. See IBC Section 1604.4 and 1613.1, and ASCE Sections 12.3.3.1 and 12.7.3. 5. The roof includes multiple drag trusses. The loads should be designated as ASD or LRFD. 6. The purpose of the drag truss on Grid 3 should be clarified. This truss does not appear to connect to any vertical elements. 7. Deferred Submittal Note 1 on Sheet SN1 should be revised to require the FOR to perform a comprehensive review of the documents. This is in lieu of submitting these items to the CoE for additional permits. Alternatively,these items will require additional permits prior to construction. Please contact me if you have questions. Thank you. 1
