curtain wall or does it break at every fin

Plasterform Questions
o GFRG Ceiling Cove: From the A33-53-00-00-00 CAD files there are three different
angles. How does the 42.7 degree angle transition to 54.4 degree angle along BB’ and BR
line between B5’ and B7’? How does 54.4 degree angle transition to 21.4 degree angle
along BQ and BA line between B3’ and B1’?
o GFRG Ceiling at Retail: There is a triangle of GFRG ceiling shown on the RCP between
B6’ and B7’ in the retail area. There is no section thru this area of the ceiling and could
not locate required information on the Revit model. Please provide design at this area.
o GFRG/Structural Steel Clash: A36-52-00-00-00 and S32-11-00-00-00 were overlapped
and it was found the steel trusses don no always fit into the GFRG closure. Which
drawing should be followed for geometry? Can we follow S32-11-00-00-00 (Rider B
dated 4-13-2018) and modify GFRG truss closure angles on A36-52-00-00-00? For most
slanted truss closure between grid B1-B9 is it acceptable to make the angles 62/63/64/65
degrees?
o Joints at Truss Elevations: There are three lines shown on the truss elevation. Is the top
joint a control joint for movement? Is it acceptable for the bottom joint to be a reveal? A
tape joint may have some quality issues between the GFRG and GFRC.
o Tapered Truss Corners: Some truss corners are tapered from 4” at shaft bottom to 0” at
the top of the shaft. To Is it acceptable to keep the tapered portion length fixed and put
difference at square edge portion on the top?
