Nothing it produces is signed, sealed or stamped, and it isn't a design or calculation of record, a delegated-design submittal or a shop drawing. It sizes the vertical mullions, jambs and horizontals, screens the glass for wind (ASTM E1300) and for story drift, and estimates anchor loads; cantilevers, buckling, torsion, door loads, anchor and embed capacity, seismic and thermal movement of the framing, and the final glass design are left to final design by the delegated-design engineer after award.
