Geotechnical Engineering
Our geotechnical engineering services assess subsurface conditions for construction projects. We analyze expansive clays, collapsible soils, and slope stability to provide foundation recommendations. Our team conducts field evaluations and laboratory testing to ensure safe, cost-effective site development solutions for residential, commercial, and infrastructure projects.
Environmental Engineering
Environmental engineering services include Phase I and Phase II site assessments, contaminated site investigations, and compliance audits. We identify environmental liabilities and develop remediation plans for properties affected by petroleum hydrocarbons, solvents, and heavy metals. Our team ensures regulatory compliance with federal, state, and local requirements.
Materials Testing
We provide comprehensive materials testing for construction projects, including concrete, asphalt, steel, and masonry. Our certified technicians perform compressive strength tests, flexural determinations, and aggregate analysis. These services ensure structural integrity and compliance with ASTM standards for commercial, government, and healthcare facilities.
Laboratory Services
Our full-service laboratory offers soils testing, structural steel analysis, and custom load testing. Accredited under ASTM C1077 and Caltrans-certified, we perform permeability tests, triaxial compressive strength assessments, and specialized material evaluations. The lab supports construction projects with accurate data for engineering decisions.
