Services
Geotechnical Engineering
Our geotechnical engineering services assess subsurface conditions to determine optimal foundation systems. We conduct comprehensive site investigations and develop tailored solutions for residential, commercial, and municipal projects. Our expertise includes slope stability analysis, seismic design, and ground improvement techniques.
Soil Testing Services
Our ASTM-certified laboratory performs soil testing to determine engineering properties. We analyze moisture content, density, and shear strength to inform foundation design. Testing supports both our projects and external consultants' requirements across New England.
Construction Monitoring
We provide on-site construction observation for geotechnical activities. Our engineers monitor fill placement, compaction, and foundation preparation. Real-time assessments ensure compliance with design specifications and address unexpected subsurface conditions.
Subsurface Exploration
Our subsurface exploration programs characterize soil and rock conditions. Using advanced drilling techniques, we gather data for foundation design and earthwork planning. Services support infrastructure projects ranging from residential developments to federal facilities.
Groundwater Analysis
We evaluate groundwater flow and contamination risks for development projects. Our analysis informs drainage solutions and regulatory compliance. Services include aquifer testing and remediation planning for industrial and municipal clients.
