Environmental remediation is complex. Every environmentally impacted site is different, so your site remediation approach must uniquely address your legacy site issues or recent incidents.
We bring clarity and certainty by developing solutions that address your site’s unique conditions and objectives. Our focus is on providing remediation investigation, characterization, design, execution and site closure that is cohesive and comprehensive. As a multidisciplinary engineering firm, we provide remediation solutions for projects from the small and simple to the large and complex.
Our Progressive Remediation Strategies (PROGRESS) approach applies next-generation technologies and practices to the remediation of complex contaminated sites. PROGRESS addresses the inherent uncertainties of remediation — including unseen subsurface conditions — by emphasizing the site geologic model and quantification of subsurface processes that drive remediation performance. The PROGRESS approach delivers focused, cost-effective remedies that produce predictable results.
Our site remediation capabilities range from construction-intensive facility decommissioning and demolition and former manufactured gas plant (MGP) site remediation to passive in situ groundwater remediation and monitored natural attenuation. We are industry leaders in vapor intrusion characterization and mitigation, risk assessment, and regulatory negotiation and provide environmental emergency response services to address the most challenging, high-risk incidents.
Our team also has extensive experience assisting power generation utilities with the environmental aspects of coal combustion residuals (CCR) management, including hydrogeologic site investigations, groundwater monitoring, modeling and analysis, and corrective action and evaluation. Our experience also includes comprehensive services for the study, permitting, design and construction of utility waste landfills, including facility life evaluations, disposal alternatives, ash utilization and ash handling.
We begin with the end in mind for seamless regulatory risk management, cost savings and expedited site closure. Your objectives guide us in evaluating risk and cost/benefit and developing strategies for regulatory negotiations and site management. Depending your objectives and risk profile, we can respond aggressively or consider passive, low-cost remedies as preferred alternatives to costly remedial actions.
Unforeseen costs are a common challenge facing remediation programs. We incorporate your business priorities into every stage of the remediation process and leverage our extensive engineering and estimating resources to accurately project costs. With our PROGRESS approach to complex site remediation, our technical teams focus on the site conditions and processes that pose the greatest uncertainty and cost risk, dramatically improving the cost-efficiency and certainty of the chosen solution. When necessary, we implement probabilistic cost forecasting to yield a more complete picture of the estimated cost range, as well as evaluate the likelihood of exceeding a particular cost point. We apply this robust tool to help clarify the uncertainty inherent in environmental remediation, boosting your budget confidence.
Our PROGRESS approach delivers focused remediation solutions that leverage the unique characteristics of your site, aiming to reduce uncertainty, deliver lower risk and cost, and support precise, predictable results. Key components of our process include:
Our consulting, environmental engineering and geology, environmental construction, and remediation services are fully integrated and can be implemented through your preferred project delivery method: engineer-procure-construct (EPC)/design-build; design-bid-build; owner’s engineer; construction management; or program management.
Throughout the course of your site remediation project, we deliver ongoing services that address your specific needs, including:
