Groundwork Solutions
We deliver integrated groundwork solutions that address complex environmental challenges with confidence. From legacy contamination and high-risk remediation to closure, decommissioning, and long-term stewardship, we partner with public and private-sector clients to manage risk, control cost, and achieve durable environmental outcomes.
Our groundwork capabilities span the full project lifecycle, from investigation and treatability testing through engineering, construction, and post-closure operations. By combining deep technical expertise with program-level management, regulatory insight, and a strong safety culture, we advance projects efficiently while meeting environmental, operational, and sustainability objectives.
Our teams are experienced in working across highly regulated environments and challenging site conditions, including dense urban settings, remote locations, and operational facilities. Clients rely on us not only for technical execution, but also for disciplined planning, risk management, and lifecycle cost control.
Mining Environmental Management And Innovation
We deliver comprehensive reclamation, remediation, and closure services to mining and industrial clients worldwide. Leveraging decades of experience managing large, complex programs, our solutions are tailored to meet each site’s specific technical, regulatory, and operational requirements. Utilizing our advanced treatability laboratory for both bench- and pilot-scale testing, we develop precise remediation strategies and provide data-driven insights that enable our clients to fulfill regulatory requirements while achieving lasting environmental and operational goals.

Oil And Gas Decommissioning
Our experts deliver efficient, innovative integrated decommissioning and remediation solutions for upstream and downstream oil and gas assets, helping clients achieve safe, compliant, and cost-effective closure. Our teams support projects from site investigation and risk assessment through in situ remediation, demolition, and long-term monitoring. We help clients manage asset retirement obligations by balancing regulatory requirements, stakeholder expectations, technical constraints, and cost considerations, reducing residual liability while restoring sites for future use.
Munitions And Chemical Warfare Materiel Remediation
Remediating munitions, hazardous, toxic, and radioactive waste, and chemical warfare materiel requires an uncompromising focus on safety, precision, and regulatory confidence. We bring decades of experience and advanced technical capabilities to help clients manage risk and restore these sites for safe, productive use.
Military Munitions Response Programs (MMRP) Services
We deliver advanced solutions to remediate military munitions, hazardous, toxic, and radioactive waste (HTRW), and Chemical Warfare Materiel (CWM), protecting people and restoring environments for safe, productive use. Our approach combines advanced geophysical methods, robust safety protocols, and innovative engineering to address complex, high-risk sites.
Geophysics
We provide high-resolution subsurface mapping and advanced classification for both land and water environments. Our team integrates digital geophysical mapping (DGM), advanced geophysical classification (AGC), LiDAR, aerial imagery, and drone surveys to deliver precise, site-specific solutions. These tools help minimize ecological and cultural impacts while maximizing project efficiency and value.
AI Crater Identification
Our advanced, AI-driven solution revolutionizes the identification of bomb-related craters across large, formerly used defense sites by leveraging high-resolution Light Detection and Ranging (LiDAR) elevation data to accurately detect, classify, and analyze terrain anomalies, ultimately delivering precise, reliable, and actionable results that support efficient site assessment, risk mitigation, and informed decision-making.
