2. Sheet S-100 Entry Canopy Framing Plan: The column sizes for the canopy support framing
do not appear to be noted on plan. Please provide.
3. Sheet S-103 Upper Floor Framing Plan: The lateral loads being transferred into Braced
Frame #1 at the elevator/stair openings appear to be very high. Please provide
calculations and details that indicate how these lateral loads are transferred into the
braced frame without a floor diaphragm.
4. Sheet S-202 Braced Frame Details/Elevations: The overturning forces at Braced Frame
