By removing the top section first with the carriages, time was saved by not having to crank down the carriages and not having to remove and replace braces as the carriages came down.
Assistant superintendent Pat Patterson said he alternated cable-jumping by installing half of the cable at nine-foot intervals and the other half at 18-foot intervals. This saved time by avoiding jumping the whole system at once.
Patterson added the time saved by the crane-moving system was enough to pay for the scaffolding. In addition. the scaffolding helped speed masons' production. Seven masons using three laborers laid a floor per day per panel. The job required 425,000 brick.

The crane easily moves the six 72-foot tower sections to their new position.

The crane moved the six topmost inserts, along with the movable carriages and scaffolding planks, to a new wall and lowered them to fit into six bases that had already been set in position along the wall. The inserts were secured and the spreader bar released.
Then the crane swung the H-beam back to the remaining 72' high towers, and the beam was secured to the tops of them. Six laborers removed the stiff arm braces that secured the scaffolding to the wall.
The crane picked up all six towers high enough off the ground so that the six tower bases could be removed. The crane then swung the six 72-foot high sections to the new wall, lowering them into the first 9-foot sections which were now on the bottom instead of the top. Six laborers climbed up the towers, securing them to the steel or con-
