Representative Subsurface Investigation Projects
Atoka Water Transmission Tunnels, Oklahoma - DSC Site Investigation
Golden Geotechnics was contracted by the MTBM tunnel contractor during construction to provide a multi-phase geologic investigation that included rock core boreholes to accurately characterize the complex lithologies on the site. The investigation was able to show that the conglomerate was an order of magnitude stronger than baselined and abrasivity values four times the baselined value to support the differing site condition claim.
Pikes Peak State College, CO - Landslide Investigation
Golden Geotechnics was part of the design-build team contracted by PPSC to investigate, design and build slope instability mitigation at the firing range complex of the PPCC Public Safety Training Facility. The hillside of the Firing Range complex was undergoing progressive slope failure resulting from heavy-rainfall induced slope degradation that has encroached to the foundation of the training building and undermining utilities. GGI performed a desktop analyses combining publicly-available data and air photo analysis with historic PPSC facility investigations to develop a targeted site investigation to answer outstanding and specific design questions.

Turkey Peak Dam, TX* - Site Investigation
GGI Principal Sean Sundermann was the site investigation program lead and lead field geologist on a multi-phased data acquisition program for the Turkey Peak Dam, a new reservoir on Palo Pinto Creek for Mineral Wells, TX to evaluate geologic conditions identified previously in the dam foundation footprint that could result in foundation sliding failures. Program integrated subsurface exploration, acoustic televiewer, dilatometer testing, deep trenches, geophysics, and PCPT to characterize the foundation footprint, investigate adverse conditions, and provide design inputs. Completed evaluation on abutments providing positive evidence for a lack of deep-seated instability.
