On Sheet A2.0, plan notes indicate a dwelling-garage separation for walls. However, it does not appear to contain notes for fire-resistive protection for the habitable spaces above the garage. Please verify and revise notes and plans as required. IRC Table R302.5. - Per ESG Design response 2. On Sheet A4.1,a glulam 5.125 x 15 or 6.75 x 13.5 is proposed to transfer both gravity and overturning forces from the 2 nd floor shearwalls. The permit calculations appear to show a gravity design load check, but does not appear to verify that the proposed glulam can withstand a combination of overturning forces in addition to the gravity load. Please verify that this beam and its supporting construction are adequate to carry the load combination with lateral load overstrength factors. Also,details to transfer the overturning forces from the shearwall into the glulam beam appear to be missing. Please clarify the transfer detailing for these conditions. ASCE 7-10 12.3.3.3, 12.4.3, IRC R106.1.1. New calculations included for GIB(Sht.A4.1)for the load combination of gravity and overturning forces from shear walls above. Revised for GIB 6 3/4x16''A,dbl.joists under shear wall above and Simpson MST 36 at each end of shear wall around the floor joists.
