2015-0032 Memory Care.pdf City of Edmonds PLAN REVIEW COMMENTS BUILDING DIVISION (425) 771-0220 DATE: March 30, 2015 TO: Edmonds Memory Care, LLC jeff@rjdevelopmentservices.com FROM: Andrew Gahan, Plans Examiner RE: Plan Check: BLD2015-0032 Project: New Commercial Building th Project Address: 7208 & 7220 210 Street SW During a review of the plans by the Building Division for the above noted project, it was found that the following information, clarifications, or changes are needed. A complete review could not be performed until the revised plans/documents, including a written response indicating where the ‘clouded’ or otherwise highlighted changes can be found on the revised plans, have been submitted to a Permit Coordinator. Reviews by other divisions, such as Planning, Engineering, or Fire, may result in additional comments. Again, please note that a complete review could not be performed by the Building Division, and therefore may result in additional comments during any subsequent reviews. Structural Calculations 1.The minimum snow load typically accepted within the City of Edmonds is 25 PSF due to the high moisture content of snowfall in this area in addition to the high probability of rain subsequent to a snow event. Please revise calculations or verify the adequacy of the structural members selected. 2.The seismic design category for this site address is D. Please revise the calculations. 2 3.The calculations show options for rafters of various sizes, grades and materials, however the only option on the plans refers to a manufacturer (Hambro) designed layout. Please clarify. a.Additionally, no roof layout from Hambro was provided. If no roof framing layout is provided at the time of resubmittal, please note on the plans that the roof framing will be a deferred submittal item. 4.It appears that the column design provided utilizes the f (perpendicular) for Douglas Fir. c That would require Douglas Fir mud sill plates throughout the structure. Verify the use of Douglas Fir mud sill plates or revise the calculations for Hemlock Fir. 5.The lateral design shows that the Response Modification Factor, R, used in calculating lateral loads is 6.5. That value for R is reserved for light-weight, wood-framed construction. This structure also consists of concrete and masonry shear walls at the lower level. Please revise the calculations as required. Structural Plans: 6.Sheet S-1 a.Revise allowable soil bearing pressure to match that provided in the geotechnical report and which was used in the structural calculations. b.Verify the use of the correct Seismic Response Coefficient, R. 7.Sheet S-1.2 a.Detail F i.Provide the complete beam call-out. ii.Describe how the lateral load generated by the concrete slab will be transferred to the decking and steel beams. b.Details J and K – Please complete the details. 8.Sheet S-1.3 a.Detail H – Specify vertical reinforcement spacing. 9.Sheets S-2.1a and S2.1b – This sheet number (as listed in the ‘Structural Sheet Index’) does not exist. Instead, Sheets H1.1-EST and H1.2-EST were included in the plan. Additionally, those sheets that were included are incomplete, and do not include a beam schedule. Please reconcile the Structural Sheet Index with the actual sheets included, verify that those sheets are complete, and include a beam schedule to help guide proper review, construction and inspection. 10.Sheets S3.1a and S3.1b – See comment 9 above. Reference Sheets H2.1-EST and H2.2-EST included in the submittal set. 11.Sheet S4.1 a.The roof trusses 1.1 through 1.13 have not been specified on the plans b.Many of the structural elements listed on this sheet are inconsistent with the calculation package, the framing plan, or both. Others were not readily located on the plans. Please reconcile the plans to match the calculations and vice versa. The elements observed to be in error include: 2.3, 2.4, 2.6, 2.7, 2.11, 2.12, 2.13, 2.20, 2.25 and 2.31. Additional structural elements were found to be incorrect. Those elements are identified under comment 13b, because those elements are specified on the sheet associated with that comment. Again, please note that the next review of the structural sheets may result in additional comments. c.Two of the detail bugs have a sheet number referenced but no detail number referenced. Please update. d.Provide a detail bug for all the applicable details. Remove extraneous details from the plans. 12.Sheet S4.2 a.The structural notes included on this sheet should be removed since the note at the end of the structural notes on Sheet S-4.1 reference Sheet S-4.3. b.Detail D – the beam 2.4 referenced is in error. Please revise. c.Detail H – for consistency, please reference the beam by the member number it was assigned. d.Details I and K– The member numbers referenced are in error. Please revise. 13.Sheet S4.3 a.Detail E – specify the strap to be used. b.Per comment 11b above, the following structural members were found to be in error: 2.36, 2.40, 2.41, 2.42, 2.43 and 2.45. Again, please note that the next review of the structural sheets may result in additional comments. Page 2 of 3 14.Sheet S-5.1 a.Several detail bugs appear to be incomplete. Please revise. b.Include shear flow details for shear walls of each material, especially where non-like materials interface. c.Concrete Shear Wall Schedule and Notes – Specify the rebar spacing. Include detailing for the concrete shear walls. d.Include structural detailing for the masonry shear walls. 15.Sheet S-5.2 a.See comments 14a through 14d above. 16.Sheet S-5.3 a.References to shear wall details are confusing and incomplete. This sheet does not explain where the associated specifications can be found. Additionally, the following sheet, Sheet S-5.4 does not contain some of the details referenced, and some of the details do not match the walls where they are referenced. Please revise. 17.Sheet S-5.4 – verify that each of the details is correctly referenced on the plans. Some were found to be in error. Page 3 of 3
