BURT18530 MERIDIAN AVE N. ENGINEERING SHORELINE, WA 98133 iomE. 7. Sheet 51.1 shows a new footing at Grid B/1.1 and references Detail D/S2.1. See IBC Sections 107.2.1 and 1603.1. The following comments should be addressed: a. The plan indicates the existing footing includes a plinth and that a new wood post shall be installed below the existing beam with a cast -in connection. The detail does not show this level of detail and should be revised. The Simpson product required should be specified. b. The detail does not specify a required thickness and instead appears intended to match the existing footing. The thickness of the existing footing does not appear to be known. A minimum thickness for the new footing should be specified. c. The required width of the foundation measured perpendicular to the face of the existing foundation should be specified. Response: Items a, b and c is now shown on Detail DIS2.1 8. The footing at Grid B/2 on Sheet S1.1 appears to support a design load of at least 10 kips. This exceeds the allowable bearing capacity at the footing. Calculations substantiated the design of the footing including soil bearing shall be submitted for review. See IBC Sections 1604.1 and 1605.3. Response: See revised footing calculations. Footing size revised on plan sheet S1.I to match calculations (3'-0"x3'-0"x10') Gravity System: 9. Sheet A2.1 indicates existing beams on Grids 13/1-2, C/1-2, and 2/13-C will be replaced by new beams. The Floor framing Plan on Sheet 51.1 does not indicate replacement of beams at these locations. The structural design should be coordinated with the architectural drawings and revised as needed. Calculations substantiating modifications to the gravity system shall be submitted for review. See IBC Sections 1603.1 and 1604.1. Response: Beams to be replaced are at the roof level. Beam at grid 2/B-C shall remains and will not be replaced.
