Environmental consulting services address contamination assessment and remediation strategies for industrial and commercial properties. We specialize in PFAS mitigation, vapor intrusion analysis, and brownfield redevelopment projects. Our team combines regulatory expertise with technical solutions to achieve compliance and restore property value.
Subsurface Exploration
Subsurface exploration services employ advanced drilling and sampling techniques to characterize underground conditions. We maintain specialized equipment for soil and rock analysis, groundwater monitoring, and geotechnical testing. Our capabilities support foundation design, tunneling projects, and environmental site assessments across diverse geological settings.
Forensic Engineering
Forensic engineering services investigate structural and foundation failures to determine root causes and remediation requirements. We analyze soil-structure interactions, construction defects, and environmental impacts affecting building performance. Our expert testimony and technical reports support insurance claims, litigation, and repair planning.
Property Condition Assessment
Property condition assessments evaluate building systems and site infrastructure for real estate transactions. We identify environmental risks, structural concerns, and regulatory compliance issues during pre-acquisition due diligence. Our reports help clients understand capital expenditure requirements and potential liabilities associated with commercial properties.
