Skip to main navigation Main Navigation Geosciences Services / Geoprofessional / Geosciences Construction Support – Geoprofessional Environmental – Geoprofessional Geosciences Geotechnical Geostructural Infrastructure Monitoring Laboratory Testing Risk – Geoprofessional Our clients value our specialized skills and experience in geology, geophysics, groundwater hydrology, seismology, and rock mechanics. One of Schnabel’s key strengths is recognizing and addressing geological issues so they can be addressed at the appropriate design level, thus avoiding unexpected issues that cause cost overruns and schedule delays. Our geoscience professionals work closely with geotechnical and geostructural engineers and environmental scientists to provide full-service site investigation and characterization services. Our expertise is in identifying and understanding geologic hazards as well as the impacts of complex subsurface conditions on engineering design and construction issues.
