A complete review cannot be the revised plans/documents, including a written response indicating where the performed until ‘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. Items that recur on this list appear in italics. On sheet A-2 – Elevations 1.Stair and Railing a.Change the code section for the required stair width from ‘R311.5.1’ to ‘R311.7.1’ to reflect the currently adopted 2012 International Residential Code (IRC). b.Change the code section for the required handrail height from ‘R311.5.6.1’ to ‘R311.7.8.1’. c.Change the code section for the required stair illumination from ‘R311.5.7’ to ‘R311.7.9’. On sheet A-3 – Scheme, Plan, Detail, CS 2.Guardrail Attachment Soffit and Insulation Detail – Clarify the reference to the ‘FHA 1/300 rule’ regarding the required roof ventilation. The applicable code requires a net free ventilation area of 1/150 of the area of the vented space per IRC R806.2. Indicate on the plans the minimum number of, or length of, the specified soffit vents to be installed to meet this requirement. 3.Plan a.Clarify the callout for the 4x8 HF #2 beams to be used to support the loads over the two windows immediately below the proposed roof deck on the north side of the structure. They appear to be over spanned and fail in bending. The ‘Beam Loading’ in the provided beam calculations should be using floor loading criteria. b.Clarify the callout for the 2x6 HF #2 beam to be used to support the loads over the window immediately below the proposed roof deck on the south side of the structure. It appears to be over spanned and fails in bending and in shear. The ‘Beam Loading’ in the provided beam calculations should be using floor loading criteria and it does not appear that the point load from the girder truss has been accounted for.
