SUBJECT: REBAR

Drawing/Spec Ref: both

Information Requested: (1) The legend on cs401 & cs501 do not match. We are assuming the legend on cs401 is correct. in this case (2) Assuming the legend on cs401 is correct, the "c" line running north-south in the middle of the paving should be tied joint not thicken edge? (3) Key note 7 on cs101 shows the area south of the ramp/dock to be slab on grade. The same area on cs401 is shown to be paving. Which one is correct? (4) If the slab-on-Grade is intended in this area, what size rebar is to be used? Detail B-B on CS502 shows this area to have #4 @ 12"cc- both ways General--note VI, 1A on page GS102 shows Slab-on-grade to have #5 @ 12"cc-both ways (5) General Note IV, 2 shows rebar to be A613, A616 or A617. A613 is a retired spec for nuclear application. A616 is a rail steel spec A617 is an axle steel spec. Prime rebar (non-weldable) is Manufactured to the A615 spec. is this acceptable? (6) The Ramp on CS502 appears to start at Detail B-B, and the wall underneath the ramp to start north of that line. What is underneath the ramp in this area? (7) If the wall starts15' north, minimum VARIABLE height of the wall could not be 4". It would have to be 18" minimum VARIABLE height on the 10% slope of the ramp. This is based on the 24" constant wall height at grade. Are Top of Wall elevations available?
