Geology & Geotechnical Engineering

We evaluate surface and subsurface conditions through drilling, test pits, trenching, and geologic mapping to understand site constraints, identify potential hazards, and collect samples for laboratory analysis.

We prepare engineering geologic reports that document site conditions, geologic hazards, and development considerations to support planning, design, permitting, and regulatory review.

We provide geotechnical recommendations for foundations, retaining walls, grading, drainage, and construction based on field exploration, laboratory testing, and engineering analysis.

We assess existing and proposed slopes, excavations, and earthwork to evaluate stability and support safe, feasible development.

We evaluate the potential for liquefaction, settlement, and lateral spreading during seismic events and provide recommendations to help reduce project risk.

We conduct seismic investigations, including fault studies and trench logging, to identify fault activity and assess potential impacts on development.

Our in-house laboratory performs physical and chemical testing of soil and rock materials in accordance with ASTM and other applicable industry standards.

We provide geologic support and percolation testing for onsite wastewater treatment systems, helping determine appropriate system design, placement, and feasibility.

We perform infiltration testing to evaluate stormwater management feasibility and support the design and sizing of drainage facilities.

Our field technicians provide grading observation, density testing, and construction inspections to help verify compliance with project requirements and approved plans.
