Construction workers recently completed a 27-hour concrete foundation pour for the $450 million Northwestern Mutual Tower and Commons project at the firm’s downtown Milwaukee corporate headquarters campus.
During the marathon session, more than 250 construction workers poured 10,000 cubic yards of concrete. The pour required 50 cement trucks that made 1,000 trips around the clock. The trucks transported cement from three different plants, located in Milwaukee’s Bay View neighborhood, West Allis and Menomonee Falls.
Menomonee Falls-based Sonag Ready Mix provided the concrete. The rebar installation was done by Menomonee Falls-based Choice Construction Inc. For this phase of the project, Milwaukee-based Daar Engineering did site survey work and Pewaukee-based Professional Service Industries did material testing work. The general contractor for the Northwestern Mutual Tower and Commons project is a joint venture of Gilbane and Milwaukee-based CG Schmidt.
Construction of the 32-story, 1.1 million-square-foot building is expected to be complete in 2017.
