Somers Cc: 'mark.thunberg@co.snohomish.wa.us'; 'Ryan Ellinghaus'; Tony Lee Subject: City of Everett Permit Services: 3200 Cedar Street (131802-011) Peter, I have reviewed the submittal documents for this project. There are still a few comments that are not completely addressed. I'm sending these via email rather than a formal letter to expedite this review. Comments are itemized for consistency with the original letter: The size of the weld in Detail 17/S-603 should be specified. The provided response does not appear consistent with the comment. Please review and revise as needed, or clarify the response. 434b. The following should be addressed: u--"*' The design of the piles appears to be a deferred submittal. The piles should be listed on Sheet S-003 in the "Deferred Structural Submittals" section. The pile design loads appear to exceed the values specified in Table 7/S-401. The tabulated values and the calculated loads both appear to be ASD values. See calculation pages 1047-1048 and 1055-1056, and page / 15 of the geotechnical report. tip Verify the correct micropile types are specified for each location on Sheet S-200. V5. This comment does not appear to addressed by the submitted calculations as indicated. Please specify the pertinent calculation pages for each comment. /6d.he loading inputs appear to include the 15 psf partition loads as a dead load instead of a live load. See IBC Section 1607.5. 1� f. T e load combinations appear to be horizontal forces only. Verify where the vertical component is included. pp Y fY p 1g. Include the input file for the automatically -generated load cases. V The participating torsional mass is only 65.6% per page 4027. The participating mass shall be minimum 90% per ASCE 7-10 Section 12.9.1. Note that the analysis requires,a lot of modes to reach the 90% threshold, which can adversely affect the overall analysis. Verify if the sources of the small modes is attributed to non -lateral motions of the building system, and if they can be eliminated. Verify the analysis accurated models the response of the building. �3c. The calculation of the response scale factors on page 4026 are not clear. Provide documentation clarifying the scale factors. The comment asked for clarification that different floor weights representing the new and existing construction have been used. Identify where the calculations verify these weights.
