The pour required 250 truck loads, delivered in mixers similar to this Ozinga ready mix truck.
A foundation pour in Chicago took 12 hours and 250 loads of ready mix concrete. The foundation is for a 72-story tower just west of Navy Pier sandwiched between the Chicago River and the Ogden Slip.
An article on Urbanize described the project as a collaboration with LR Contracting Co. and BOWA construction.
The foundation required 2,300 cubic feet of concrete, weighing more than 9 million pounds, according to the article. Aerial photos show the circular foundation surrounded by 10 Ozinga concrete mixer trucks and two concrete pumps. The pour required 25 concrete truck drivers.
