During a review of the plans by the Building Division for compliance with the applicable building codes, it was found that the following . information, clarifications, or changes are neededReviews by other divisions, such as Planning, Engineering, or Fire, may result in additional comments that require attention beyond the scope of this letter. Items that recur on this list appear in italics. A complete review cannot be performed until the revised plans/documents, including a written response in itemized letter format indicating where the ‘clouded’ or otherwise highlighted changes can be found on the revised plans, have been submitted to a Permit Coordinator. nd Resubmittals must be made at the Development Services Department on the 2 Floor of City Hall.

On sheet S6 – Main Floor Shearwalls & Framing Above: 1.Main Floor Shearwalls & Framing Above a.Clarify on the plans the callout for the ‘HDR’ - (2)2x6 beam - over the ‘plan north’ window in ‘Bath #1’ of ‘Unit 15’. It appears to be over spanned and fails in bending The HDR over the and in shear. The response to the plan review comments states: “ “plan north” window of Unit 06 has been calculated as beam (1-23). (2)-2x6 are adequate to support the loading conditions at that location. The point load below the ‘plan east’ end of ‘Beam 2-2’ – 4x10 DF #2 – does not appear to have been accounted for. b.Clarify on the plans the callout for the ‘HDR’ - (2)2x6 beam - over the ‘plan south’ door in the ‘Entry’ of ‘Unit 15’. It appears to be over spanned and fails in bending. Beam calculations for ‘Beam 1-17’ could not be found among the submitted A construction documents. The response to the plan review comments states: “ calculation for Beam (1-17) was performed and determined (2)-2x6 beam is adequate. ”. While a uniform load from ‘FLOOR’ appears to have been accounted for in spite of the ‘open to below’ design, the point loads below the ‘plan south’ end of the 3-1/2x9 GLB 24F-V4 and the ‘plan east’ end of ‘Beam 2-6’ – 4x8 DF #2 – do not appear to have been accounted for. Also note that when designing the beam, the span shall be taken as the distance from face to face of the supports, plus ½ the required bearing length at each end per the American Wood Council (AWC) National Design Specifications for Wood Construction (NDS) 3.2.1. c.Clarify the difference in the representation of a fireplace in the ‘Living Room’ of ‘Unit 16’ and of that on sheet ‘A04’. The response to the plan review comment We changed our documents to match the architects plans in regards to states: “ the fireplace. ”. Sheet ‘A04’ does not represent a fireplace in the ‘Living Room’ of ‘Unit 16’. On sheet S7 – Main Floor Shearwalls & Framing Above: 2.Main Floor Shearwalls & Framing Above - Clarify the difference in the representation of a fireplace in the ‘Living Room’ of ‘Unit 14’ and of that on sheet ‘A05’. The response to the We changed our documents to match the architects plans plan review comment states: “ in regards to the fireplace. ”. Sheet ‘A05’ does not represent a fireplace in the ‘Living Room’ of ‘Unit 14’. On sheet S8 – Upper Floor Shearwalls & Framing Above: 3.Upper Floor Shearwalls & Framing Above - Clarify on the plans the callout for ‘Beam 2-12’ – 4x8 DF #2 - over the ‘plan south’ window in the ‘Living Room’ of ‘Unit 15’. It appears to A be over spanned and fails in bending. The response to the plan review comment states: “ new beam calc (2-12) was assessed for the HDR over the “plan south” window in the Living room of Unit 15. It was determined that the HDR should be sized as a 4x8 to have capacity large enough to carry the demand load. ”. The point load below the ‘plan east’ end of ‘Beam 3-4’ – 3-1/8x9-1/2 GLB 24F-V4 – does not appear to have been accounted for. Page 2 of 2
