Above: Here is the ladder-tepe steel framework. The slabs of granite will cover this. An unusual rail-and-chain mechanism heists the material upward. Two crane rails, one at the sixth and another at the fourteenth floors, run horizontally around the building.
Above: At each floor level shelf angles were bolted to the steel beams. The huge granite slabs will then be seated on these angles and aligned.
Above: Foreground shows panels in position with temporary ties of stainless steel. Dowel holes are in top of slab. Shelf angles are shown on scaffolding ready for installation. Background shows bricklayers making a final landing of one of the large slabs.
Above: After the slab has reached the proper floor level, bricklayers carefully swing the granite into position.
Left: Into each of the dow holes stainless steel pins inserted. Clamped to an absolutely vertical position while lead is poured. Above: Pins in place ready to help position the next slab.
