Services
Environmental Remediation
We specialize in comprehensive environmental remediation for soil and groundwater contamination. Our services include site assessment, feasibility studies, and implementation of remediation systems using technologies like soil vapor extraction, pump-and-treat, and in-situ chemical oxidation. With expertise in regulatory compliance under RCRA and CERCLA, we deliver cost-effective solutions for industrial, commercial, and municipal clients.
Structural Engineering
Our structural engineering services cover analysis, design, and construction oversight for residential, commercial, and industrial projects. We specialize in seismic retrofitting, base-isolated structures, and historic building underpinning. With a focus on safety and sustainability, we provide expert witness services and construction defect evaluations for both new builds and existing structures.
Groundwater Modeling
We employ advanced groundwater flow and contaminant transport modeling to assess aquifer behavior and remediation strategies. Using MODFLOW and MT3DMS software, we simulate chemical migration, design hydraulic barriers, and allocate responsibility among multiple parties. Our phased modeling approach ensures accurate predictions for regulatory compliance and remediation planning.
Litigation Support
Our litigation support services combine engineering expertise with legal knowledge. We provide expert witness testimony, forensic analysis of construction defects, and cost allocation studies for environmental cases. With professionals licensed as engineers and attorneys, we deliver legally defensible opinions and mediation services for complex disputes.
Contaminant Transport Analysis
We analyze the migration of chemical contaminants in soil and groundwater using sophisticated modeling tools. Our services identify pollution sources, predict plume behavior, and design containment systems. Applications include Superfund sites, industrial facilities, and water resource management projects requiring regulatory compliance and risk assessment.
