We conduct geologic site characterization and evaluate geological and geotechnical condition, including:
- Emergency response to dam and other incidents
- Detailed soil and rock description, characterization and sample logging
- Evaluation of soil and rock slope stability
- Instrumentation consultation, installation and analysis
- Hazard analysis and risk assessment
- Foundation analysis
- Structural and discontinuity analysis
- Geologic mapping
- Subsurface exploration planning, implementation and documentation
- In-situ borehole and pit testing and analysis
- Cone penetrometer testing and analysis
- Standard penetration testing and analysis
- Specialized rope access mapping
- Foundation preparation, mapping, treatment, documentation and acceptance
- Characterization and assessment of existing groundwater conditions
- Planning, implementation, interpretation and documentation of groundwater investigation programs
- Close-range stereographic geologic mapping
- Computer-aided design (CAD) and computer-aided design and drafting (CADD) three-dimensional modeling using GIS, GPS, photogrammetry and related databases for subsurface characterization, pollutants and other physical data
- Geologic consultation and interpretation for planning, design, specifications and construction
- Geologic analysis for rock mechanics issues related to blasting, grouting, borrow, seepage, dewatering, drainage, environmental restoration and other concerns
Our available services include a comprehensive suite of geophysical testing and analysis methods, geological and geotechnical field and office methods, CAD and CADD three-dimensional modeling and analyses of geologic and geotechnical conditions, and GIS database development pertaining to geological properties. We also characterize sites for environmental restoration including the Yucca Mountain Project, a potential site for disposal of high-level nuclear waste. We perform work both domestically and overseas.
See the online version of the Engineering Geology Field Manual and the Laser and Photogrammetric Methods for Rock Face Characterization.
Our services are integrated with seismotectonics, geotechnical testing, and geotechnical engineering studies also performed by the Technical Service Center.
