2015-0410 Holzman addition-remodel - Design Lines.pdf City of Edmonds PLAN REVIEW COMMENTS BUILDING DIVISION (425) 771-0220 DATE: April 27, 2015 TO: Stephen Holzman – Stacy Klima a1_morpheus@yahoo.com FROM: Chuck Miller, Plans Examiner RE: Plan Check: BLD2015-0410 Project: Holzman addition-remodel Project Address: 925 Mountain Lane 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 cannot 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. General Review Note: 1.Indicate on the plans the location of the water heater with an EF of .82 (tankless) to be installed as the selected option (5b) to develop the required additional energy efficiency credits per Washington State Energy Code (WSEC) R406.2. 2.Indicate on the plans the means to be used to provide the whole-house mechanical ventilation per M1507.3. 3.The truss drawings shall be brought into the Permit Coordinator as a ‘deferred submittal’ for intake and review of the required ‘Girder Truss Loading’ per the provided engineer design on sheet ‘S5’ prior to truss installation per International Residential Code (IRC) R802.10.1. On sheet 1: 4.Rear Elevation – Indicate on the plans the required safety glazing for the window adjacent the tub in the ‘Master Bath’ per IRC R308.4.5. On sheet 2: 5.Foundation Plan a.Indicate on the plans the proposed use of the ‘Existing Basement’ after the construction done under the scope of work of this permit has been completed. b.Indicate on the plans the required carbon monoxide alarm per IRC R315.3. c.Indicate on the plans the required ‘R-21’ wall insulation for the finished walls of the basement comprising the building envelope per WSEC Table R402.1.1. d.Clarify the callout for beam ‘B-01’ – 3-1/2x10-1/2 24F-V4 GLB to be used to support the loads over the west portion of the ‘Existing Basement’. It appears to be over spanned, fails in bending and in shear, and deflects beyond that permitted by IRC Table R301.7. The location of point loads below the beam supporting the floor over the north end of the ‘Entry’ and the upper floor loads in the provided structural calculations appear to be different than that represented on the construction documents. e.Clarify the callout for the footing marked ‘18’ – 8x18x18 – to be used to support the loads below the east end of beam ‘B-01’ – 3-1/2x10-1/2 24F-V4 GLB. It appears to be undersized for the loads anticipated by the represented construction. f.Indicate on the plans the required minimum isolated footing to support the loads below the west end of the ‘existing beam’ shown and of beam ‘M-05’ – 3-1/2x9 24F- V4 GLB above. On sheet 3: 6.Main Floor Plan a.Indicate on the plans the proposed use of all of the existing areas after the construction done under the scope of work of this permit has been completed. b.Clarify the callout for beam ‘M-04’ - 2-2x6 HF #2 to be used to support the loads over the east window in the ‘Great Room’. It appears to be over spanned and fails in bending. The location of the roof load in the provided structural calculations appears to be different than that represented on the construction documents. On sheet 4: 7.Upper Floor Plan a.Indicate on the plans the proposed use of all of the existing areas after the construction done under the scope of work of this permit has been completed. b.Indicate on the plans the required safety glazing for the window adjacent the tub in the ‘Master Bath’ per IRC R308.4.5. On sheet 6: 8.Details – Label the provided details to coincide with the references made elsewhere to guide proper review, construction, and inspection. On sheet S1: 9.Provide a stamped, signed copy of the work done or overseen by the licensed engineer per Revised Code of Washington (RCW) 18.43.070. On sheet S3: 10.Main Floor Shearwalls & Framing Above – Clarify the callout for the 2-2x6 HF #2 (beam M-04 in the provided structural calculations) to be used to support the loads over the east window in the ‘Great Room’. It appears to be over spanned and fails in bending. The location of the roof load in the provided structural calculations appears to be different than that represented on the construction documents.
