BLD19-0917 - CHC SnoCo Addn - STRUCT Corr #1 by Beck (7-27-2019).doc July 27, 2019 Leif Bjorback Building Official City of Edmonds 121 5th Avenue North Edmonds, WA 98020-3145 Subject: CHC Snohomish County Addition (Structural Review) Permit: BLD19-0917 Per your request, Beck & Associates has completed a structural review of the drawings and calculations for conformance with the 2015 International Building Code (IBC), as adopted and amended by the State of Washington and the City of Edmonds. Our review of the plans and calculations indicates that corrections are necessary prior to permit issuance. The applicant should address the following comments in itemized letter format in addition to making corrections & revisions to the drawings. Corrections and revisions to the drawing should be clouded so that they are clearly identifiable. Geotechnical The geotechnical engineer, The Riley Group, Inc. (RGI), is required to provide a review of the plans in order to verify that earthwork and foundation recommendations have been properly interpreted and incorporated into the project design. RGI should provide a letter summarizing their review and provide any additional recommendations or corrections. All new recommendations and corrections need to be incorporated into the drawing set in response to our review letter. Reference page 12 of the Geotechnical Engineering Report, January 7, 2013. Drawing Sheets S2.01 – Foundation Plan Reference Foundation Note #11. Please review and update this note. Wording & intent are unclear. A section cut, 2A/S3.01, is located along grid 5. It is unclear what this is in reference to. Provide clarification on the plans. Reference grid 4 shear walls. There are several shear wall segments which do not have S/HDU14’s or HSS columns at the ends. Shear walls are not designed as perforated shear walls and should be provided with holdowns at each end of each shear wall segment. Section cut 7/S3.01 is called out at the intersection of grids D.9 & 4.5. It appears the callout should be to 6/S3.01. Provide coordinate. S2.02 – Roof Framing Plan A Simpson C18 x 40’-0” is called out along grid D.9. The note indicates that the strap should extend 20’-0” each side of grid ‘Z’. The reference should be to grid ‘2’, not ‘Z’. Section cut 3/S3.13 is called out at the column located at the intersection of grids X & Y. The detail shows the GLB being discontinuous over the column. However, design requires the GLB to be continuous over this column. Update the plans accordingly. S3.01 – Foundation Details Reference 2A/S3.01. Both a 6” wall and a 8” wall are called out. Please clarify. Section 6/S3.01 needs to be called out on the plans where it applies. S3.13 – Framing Details Reference 7/S3.13. It is unclear how the 5/8” mounting plate is connected to the supporting HSS post with the 5/8” diameter bolts. Please review this condition and revise as necessary. Please contact me should you have any questions.
