Crux has been selected by Kleinfelder to participate in a geotechnical investigation on the San Jose to Merced section of the California High-Speed Rail (HSR). The investigation will collect information on ground conditions and feasibility for a transportation tunnel through the Diablo Mountain Range.
Utilizing track-mounted equipment, crews have begun deep core drilling and sampling along State Route 152. Instrument installation and packer testing are being completed to collect various data, including groundwater levels and horizontal earth pressure data. Teaming up with Kleinfelder and the California HSR Authority, Crux plans to drill up to approximately 4600 linear feet by the end of August.
This is the third phase of geotechnical drilling for Crux on the HSR project. Previous work has included in-situ-testing, hydro-fracking, and performing drilling operations within Angeles National Forest, a protected and environmentally sensitive area. Crux successfully completed all borings while meeting the client’s request and complying with United States Forest Service regulations.
The California HSR intends to be the first high-speed rail in North America, connecting the mega-regions of California. Initial proposals plan for the rail to run from San Francisco to the Los Angeles Basin, with eventual expansion to Sacramento and San Diego. Once complete, the rail is anticipated to span 800 miles, with up to 24 stations across the state.
