Feature Project

ConeTec CPTu, Resistivity CPTu and Seismic Testing (Vs/Vp) – Southern California

CPTu, Resistivity CPTu and Seismic Testing (Vs/Vp) – Southern California

ConeTec was engaged to complete a site characterization program at a refinery in Paramount, CA. The project included 61 CPTu soundings up to 100 feet. In-situ testing included: Resistivity Profiling, Shear Wave Velocity Profiling for Vs100, and Compression Wave Velocity Profiling (P-wave). The scope of work was performed using a 30-ton (300 kN), Tier 4 clean-diesel engine, custom built truck CPT rig. This rig has an integrated auger drill for hardscape and fill drill-outs, and a hydraulically activated seismic beam for shear wave velocity testing. The entire scope was completed ahead of an already highly compressed schedule, and remained on budget. The ability to perform multiple services all from one rig was a considerable advantage to the execution of the program.
