"A perfect time-table was published each morning. At every minute of the day the builders knew what was going up at each of the elevators, to which height it would rise and which gang of workers would use it. On each floor, the operators of every one of the small train of cars knew what was coming up and where it would be needed."
"Down below, in the streets, the drivers of the motor trucks worked on similar schedules. They knew, each hour of every day, whether they were to bring steel beams or bricks, window frames or blocks of stone, to Empire State. The moment of departure from a strange place, the length of time allowed for moving through traffic, and the precise moment of arrival were calculated, scheduled, and fulfilled with absolute precision."
"Trucks did not wait, derricks and elevators did not swing idle, men did not wait."
