One of the most challenging tunneling projects in the world
Approximately 90% of the drinking water delivered to customers in southern Nevada comes from the Colorado River, which is captured at Lake Mead. Construction of this new intake ensures that full system capacity can be maintained at low lake levels. The $520M project consisted of a 600-foot deep intake, new 900 MGD pumping station, and 3 miles of up to 20-foot inside diameter water supply tunnel.

Fossil Creek Trail is a set of two separate paved pathways, totaling 5.3 miles, running through neighborhoods and local parks that the City of Fort Collins is working on connecting. Complicating this effort is an existing Burlington Northern Santa Fe Railroad system—a main freight corridor along Colorado’s Front Range. We worked with the city on a solution that maintained the daily train traffic by using a below grade tunnel rather than a more traditional crossing.

This deep tunnel pump station is designed to dewater 160 MG of stored CSO flow in a 24 hour period. The pump station is 240 feet below ground, housed in an underground cavern that is 35 feet lower than the nearby tunnel storage system. The cavern is approximately 140 feet long, 56 feet wide, and 65 feet high. Read MoreAnil Dean, Tunnels and Trenchless Practice Leader
The interaction of value, project needs, and the ground makes for great variety and no two projects are ever the same.

Nick Cioffredi, Tunnel Inspector
You’d be amazed how many bridges you drive over on a daily basis and don’t realize that you’re on a bridge. My job out there is to keep our neighbors and communities safe.
Steve Fradkin, Tunneling Technology Manager
