Enwave, Inc. operates North America’s largest ice battery and chilled water system.  Their system is used to provide air conditioning for over 48 million square feet of building space in Downtown Chicago.  In 2018 Enwave selected Benchmark to install a new chilled water line under the Chicago River.  The highly complex project scope included coordination with CDOT and IDOT traffic routes on Lower Wacker Dr., construction of earth retention systems over 55 feet in depth, installation of a 60” steel tunnel 25 feet below the Chicago River bed, and dual 24” steel pipes to provide chilled water to the customer.  Benchmark was able to use its problem-solving expertise and diverse capabilities to overcome numerous conflicts and deliver the owner an engineering marvel.

Benchmark is ready to help you with your construction needs.
