From a telephone interview on July 22, 2014:
Decks for the formwork are stacked at upper-right corner of the foundation. Piles of sand and gravel are for concrete. It took one complete boxcar-load of lumber to build most elevators. Everything came by rail in those days.
One thing you did, you re-used all that lumber many, many times. The inside walls of forms were all taken down, taken apart, and the lumber was all reused. We always had a crew of two or three guys cleaning lumber, taking the nails out and cleaning the concrete off of it. Slip-form lumber was seldom reused. By the time you stripped the forms out at the top, that lumber fell 120 feet to a concrete slab and by the time it got there, it was moving. So when it hit, it pretty well disintegrated.
This is probably the third or fourth day. They went about six inches an hour. The boxes were put in the forms to leave holes where they wanted a hole. On the inside, they’d want a hole to put a spout or something. They’re all pre-made and numbered. The shift foreman’s responsibility is to make sure they’re put in where they’re supposed to be. They have a given height and given location.
You always knew how high you were because in the elevator’s water shaft there was a continuous measuring stick so you knew exactly how high off the ground you were. It was important that these boxes be put in at a certain height.
You also had a continuous ladder. We used to race up and down.
You see the jacks are on the outside. The guys looking over the rails, this is the back side. Way on the other side is where the cement is coming up. You can’t see a hoist.
