I <br /> Plan Check Number PW1907-055 <br /> 2721 Wetmore Avenue <br /> Response to comments from First Building Review,August 26, 2019 <br /> Item 23 <br /> The L1 planter/terrace areas west of grid B.5 account for a 4"step and 2"slope to drain. <br /> Items 24-25 <br /> See Section A, Part 3.4 of the Supplemental Structural Calculations <br /> Item 26 <br /> The L2 slab has been clarified as a 14"slab, and account for 3"step and slope to drain for the <br /> planter/terrace areas on the east side of the units. Reference elevations are noted on sheet S2.08. Live <br /> loads have been reduced appropriately and input into the slab analysis as unreducible. Snow loads <br /> have been conservatively input as an unreducible live load. Seismic loading and load combinations per <br /> ASCE 7-10 section 12.14.3.2 with exception noted have been included. Reference updated slab <br /> calculations. <br /> Item 27 <br /> The L2 balconies are intended to be vendor designed deferred submittal items. Concrete slab edge and <br /> calculations have been updated accordingly. <br /> Item 28 <br /> Plans have been revised to show where beams FB-5 are continuous. Detail 2/S9.01 has been revised <br /> for clarification. <br /> Item 29 <br /> The beam call-outs have been corrected. Beam Type FB-3 has been incorporated at HR-1 <br /> Item 30 <br /> This has been specified on plans as HR-1. <br /> Item 31 -32 <br /> See Section C, Part C1 of the Supplemental Structural Calculations <br /> Item 33 <br /> See framing note#15 on sheets S2.11 through S2.15. <br /> Item 34 <br /> Please see the supplemental calculation.The drift snow load is calculated to be 25.8 psf which is 0.8 psf <br /> more than what we specified for flat roof snow load on sheet S1.01. However, no revision to the roof <br /> framing is needed because the roof framing is same as floor framing which means it has the capacity to <br /> carry a minimum live load of 40 psf. <br /> Item 35 <br /> The roof framing is same as floor framing which means it has the capacity to carry a minimum live load <br /> of 40 psf. <br /> Structural/Lateral System: <br /> Item 36 <br /> The lateral analysis is based on the Equivalent Lateral Force procedure per Section 12.8. <br /> Item 36.a <br /> We use model overlays to verify that the analytic model is consistent with the Revit model we use for the <br /> drawings. While not 100%congruent,the analytic model accurately reflects the Revit model <br /> dimensionally. <br /> Ez ) <br /> S <br />
