Services
Geotechnical Characterization
We conduct comprehensive evaluations of soil stability, rock properties, and groundwater behavior. Our assessments inform foundation design and address site-specific challenges, ensuring structural integrity and regulatory compliance. Clients benefit from data-driven decisions that minimize risks and optimize construction outcomes for infrastructure projects.
Solid Waste Engineering
Our expertise spans landfill planning, expansion, and closure design. We provide geotechnical evaluations, hydrogeological studies, and regulatory compliance support. Clients receive sustainable waste management solutions that balance operational needs with environmental protection requirements throughout a facility's lifecycle.
Superfund Site Remediation
We offer environmental assessment and remediation strategies for Superfund sites. Our services include regulatory support, risk assessment, and implementation of cleanup solutions. Clients gain efficient pathways to compliance while addressing complex contamination challenges in accordance with federal and state standards.
Construction Quality Assurance
We implement rigorous quality assurance protocols for environmental projects. Our team monitors construction activities to ensure specification compliance and safety standards. Clients receive proactive issue resolution and documentation that supports successful project completion and regulatory approval.
Seismicity Studies
We evaluate earthquake risks and fault dynamics for infrastructure projects. Our analyses assess site conditions and develop resilience strategies. Clients benefit from safety-focused designs that meet regulatory requirements in seismically active regions, minimizing potential structural vulnerabilities.
