Provides geotechnical analysis and subsurface investigations to support diverse infrastructure, building, and mining developments. Engineering solutions cover foundation designs, earth retention systems, slope evaluations, and pavement performance optimization.
Involves detailed soil borings, test pits, and laboratory testing to map subsurface conditions.
Delivers comprehensive geotechnical reports with bearing capacity, settlement, and deep or shallow foundation type recommendations.
Performs engineered stability analyses and design specifications for cut and fill slopes, retaining walls, and earth embankments.
Conducts subgrade soil evaluations and designs pavement sections optimized for roadways, parking complexes, and airfields.
Evaluates complex geological formations and assesses natural hazards to support civil and infrastructure development. The practice identifies potential hazards and characterizes rock mass properties to ensure long-term project safety.
Identifies and evaluates landslide, rockfall, expansive soil, and other geologic hazards affecting project sites.
Determines rock mass classification, discontinuity mapping, and engineering properties for tunnels, excavations, and heavy foundations.
Offers independent, third-party field and laboratory testing to verify compliance with structural specifications and regulatory standards. Team technicians inspect structural elements and foundational components during construction.
Conducts compaction testing, moisture-density relationship evaluations, and continuous earthwork observation to verify fill stability.
Performs field cylinder sampling, slump, air content, and temperature testing alongside batch plant inspections.
Executes Marshall mix design verification, core sampling, and density testing to ensure robust asphalt pavement performance.
Provides visual and non-destructive testing of structural welds, bolted connections, and framing assemblies.
Delivers independent owner-side quality assurance programs for large-scale public infrastructure projects, including mass transit and airport expansions.
Delivers comprehensive environmental assessments, remediation support, and regulatory compliance solutions for land redevelopment and property transactions. The practice helps clients manage liabilities and restore impacted properties.
Conducts systematic property investigations under ASTM standards to identify recognized environmental conditions and potential subsurface contamination.
Investigates soil and groundwater contamination and designs custom cleanup and mitigation plans to meet regulatory standards.
