text_A: In addition to the time constraint builders had, there were also space limitations because construction materials had to be delivered quickly, and trucks needed to drop off these materials without congesting traffic. This was solved by creating a temporary driveway for the trucks between 33rd and 34th Streets, and then storing the materials in the building's first floor and basements. Concrete mixers, brick hoppers, and stone hoists inside the building ensured that materials would be able to ascend quickly and without endangering or inconveniencing the public. At one point, over 200 trucks made material deliveries at the building site every day. A series of relay and erection derricks, placed on platforms erected near the building, lifted the steel from the trucks below and installed the beams at the appropriate locations. The Empire State Building was structurally completed on April 11, 1931, twelve days ahead of schedule and 410 days after construction commenced. Al Smith shot the final rivet, which was made of solid gold.

NO.
