Beginning the pouring of concrete for the deep foundation of the Pump and Blower Building, April 8, 1926. The contractor is using guyed tower cranes, the type typical of the time. The taller more distant tower is adjacent to the concrete mixing plant and is used to aerially transfer batches of concrete to the shorter closer tower, from which the concrete flows via the long sloping pipe. The outstanding arm of the shorter tower is also used for hoisting materials. (MWRD photo 12548)
