Geoscience Solutions

Subsurface problems are a leading cause of construction delays, cost overruns, and contract claims and disputes. Many of these problems can be avoided with better characterization and design specifically related to below-ground conditions. Schnabel’s geoscience group is particularly well-qualified to help you minimize the risks associated with complex subsurface environments and challenging geologic hazards.

Our team of geologists, geophysicists, engineers, and related scientists is recognized for its collaborative approach to problem solving through applying engineering geology, geophysics, groundwater hydrology, rock mechanics, seismology, and vibration/blasting analysis.
