- Abstract
The article provides information on the Twin Tunnels project in Denver, Colorado. A construction manager/general contractor (CM/GC) contract was awarded to the Kramer/Obayashi Joint Venture by the Colorado Department of Transportation (CDOT) for the tunnel widening project. Two structural steel canopies were erected at each end of the tunnel to provide protection from rock falls and to support steel blasting mats that were hung from the frame.
