Services
Geotechnical Engineering Reports
Our geotechnical engineering reports provide comprehensive site assessments through subsurface exploration and laboratory testing. We analyze soil properties, groundwater conditions, and seismic risks to inform foundation design and construction planning. These technical evaluations ensure compliance with regulatory requirements while optimizing project safety and cost-efficiency for residential, commercial, and industrial developments.
Fault Hazard Assessments
We conduct detailed fault hazard investigations within Alquist-Priolo zones through trenching and geologic mapping. Our analysis identifies active fault traces and establishes required setbacks for structures. This critical assessment helps clients navigate regulatory requirements while ensuring safe development in seismically sensitive areas across Southern California.
Field Observation Services
Our experienced field team provides real-time observation of grading and construction operations. We verify compliance with engineering specifications through fill control testing, retaining wall inspections, and foundation excavations. This oversight ensures proper implementation of geotechnical recommendations while maintaining project timelines and quality standards.
Liquefaction Hazard Studies
We evaluate liquefaction potential in hazard zones through borehole sampling and groundwater analysis. Our reports incorporate historical and current data to assess risks to structures during seismic events. These studies inform mitigation strategies that enhance building safety and regulatory compliance for developments in vulnerable areas.
Subsurface Exploration
Our subsurface exploration services use test pits, borings, and geophysical methods to characterize earth materials. We collect samples for laboratory analysis to determine soil properties affecting construction. This foundational data supports accurate engineering recommendations for foundations, retaining walls, and earthwork specifications.
