City: Colorado Springs

State: CO

Owner: Broadmoor Hotel

General Contractor: M. A. Mortenson Company

Project Description:

As the famous Broadmoor Hotel in Colorado Springs, CO expanded, the need for additional parking to accommodate increased visitors arose.  To accommodate the additional parking need, below grade parking was required.  The plans called for four levels of parking, thus requiring a significant excavation be made.

Schnabel Foundation Company was selected by the General Contractor to design and install the temporary shoring system.  The shoring extended around most of the perimeter of the new building, about 1,500 lf.  The maximum depth of the shoring was 50 ft.

Schnabel efficiently and safely installed the shoring through difficult ground consisting of loose sands, gravels, cobbles, boulders, and ground water.  Performance of the shoring was within anticipated movement ranges.
