project snapshot:

Nicholson constructed both temporary and permanent earth retention as support of excavation for the University of Colorado Boulder Athletic Department’s new state-of-the-art football training center. The majority of the earth retention work was focused on the new full-size indoor football practice field, which also included two-levels of below-grade parking. We were awarded this work thanks to our extensive experience as well as our ability to quickly respond to the client’s needs. Throughout the project, Nicholson worked in coordination with the design team to continually adjust, re-design, and construct the earth retention systems as the project scope progressed.
