SH 82, Snow Mass Canyon, CO
This was a highway construction project in a rugged mountain environment, in a narrow, steep valley for the Roaring Fork River, including over 500,000 square feet of retaining walls with soil nail walls, double tee walls, MSE walls, 6 bridge structures, rock blasting, cleanouts and temporary excavation support. Brierley Associates' objective on this project is to provide the client with ideas and strategies to make their bid competitive and responsive to project specifications.

Adriaen's Landing Convention Center, Hartford, CT
The project consists of two utility tunnels in rock and two in soil. Brierley Associates reviewed subsurface investigations and provided an engineering report outlining excavation and support of tunnels, dewatering and/or proposed ground improvement procedures, in addition to a finite element stress analysis of proposed tunnel alignment was conducted.

Des Plaines Tunnel System, Chicago, IL
Served as technical advisor for economizing design and construction of 10 to 30-foot diameter combined sewer overflow tunnels. The project included evaluation of tunnel lining stresses and deformations, modeling inflow and outflow from the tunnels under a variety of loading conditions, and analyzing a non-circular transition section to optimize lining design.

SH160/Wolf Creek Pass, West of South Fork, CO
Developed design alternatives (alternatives include cuts in soil and rock, fills, bridges, several types of retaining walls, and soil nail walls) for 35 different reaches of Colorado State Highway 160 to be widened through a steep mountainous canyon. This included the feasibility evaluation with preliminary costs for each, and preliminary summary of likely structures for each reach of highway for the Colorado Department of Transportation.

Fall 1997 kickoff activities included preliminary geologic mapping and slope stability in Territory volcanic tuff rock formations, glacial moraine and outwash terraces and fans, and colluvial and talus slope deposits aimed to balance slope stability for new cuts, and river encroachment and riverbank structures with overall environmental impact and mitigation.
