Tunnels

Value Through Advanced Analysis

SC Solutions has a long history of providing a wide range of services in the areas of structural and geotechnical engineering. SC Solutions has conducted designs and seismic evaluation of several tunnel structures in California using performance-based design, gaining extensive experience in designs that meet multiple seismic performance levels.

A Selection of Projects

Our project experience includes both design and construction support. Because of the complexity and schedule constraints of most tunnel projects, our engineers have developed automated systems of evaluation that enable us to provide rigorous and systematic evaluations during each stage of construction.
