Problems we solve

The Complex Challenges Our Clients Bring to Us

Our clients come to us when the stakes are too high for ordinary approaches: contaminated land that needs to be safely redeveloped, PFAS and emerging contaminants threatening operations and communities, geotechnical risk on complex subsurface projects, regulatory and stakeholder landscapes that could derail a project, climate-driven disasters demanding resilient infrastructure, environmental compliance obligations that require both technical rigor and strategic foresight, and water resource challenges spanning flood risk, groundwater, and stormwater. We solve not just the technical problem but the organizational, regulatory, and community dimensions surrounding it.

Consulting Solutions By Industry

Aerospace consulting

Infusing the best science with advocacy to achieve the simplest solutions for complex aerospace challenges, the team takes a holistic, client-centric approach — whether applying innovative technologies to treat recalcitrant and emerging compounds, or working with regulators to reduce downstream review cycles. The aerospace consulting team includes experienced scientists, engineers, construction, and remediation experts who work alongside your organization's internal and external stakeholders, finding the most efficient path to manage risk while reducing liabilities and costs. The team not only applies proven science but also develops innovative solutions based on individual challenges — whether related to remediation, aerospace infrastructure, risk assessment, or something else entirely.

Education, healthcare, and cultural institutions facilities design and construction

Connecting people, ideas, and information in meaningful ways to solve the challenges facing educational, healthcare, and cultural institutions — from securing funding and determining vital program and space requirements, to accelerating construction projects and managing unexpected disruptions such as a pandemic. From the initial stages of a project, environmental specialists and geotechnical engineering consultants work to gain an in-depth understanding of client needs, considering the entire campus and project ecosystem as well as all stakeholders. This approach — covering Higher Education, Healthcare, and K-12 and independent schools — allows for arrival at the best solution and often results in a reduction in overall project and operating costs.

Energy consulting

Offering innovative systems thinking for tomorrow's energy solutions, experienced energy consultants have built strong relationships with stakeholders and regulators — fueling the ability to plan for challenges, deliver breakthrough efficiencies, reduce costs, and proactively manage risks across advanced reactors, coal combustion residuals, electric transmission, manufactured gas plants, oil and gas transmission, renewable energy, and thermal generation. In today's dynamic energy sector, the ability to adapt and innovate is crucial. A collaborative, forward-thinking approach enables clients to meet their commitments while mitigating future risk and safeguarding their company's reputation — leveraging leaders in environmental remediation, design, risk assessment, and facility siting and permitting with a systems-thinking approach that considers the interconnectedness of all project aspects.

Environmental trusts consulting

Anticipating and overcoming roadblocks during environmental trust projects with an end-in-mind approach — managing environmental trusts is a complex, high-pressure endeavor. With so many stakeholders involved, gaining consensus on the best path forward is anything but simple, and when a finite budget encounters unforeseen surprises like previously unidentified emerging contaminants, the road ahead can look impossible. Decades of expertise in environmental sciences and underground construction enable the team to anticipate and plan for otherwise unforeseen circumstances that may emerge. Clients are brought toward their desired end goal as efficiently as possible, with a strong focus on cost certainty — combining thoughtful cost estimates and pricing models with strong project management to help clients manage under budget.

Government infrastructure consulting

Bringing big-picture thinking and ingenuity to government infrastructure projects so clients can do more with less — whether exploring airport sustainability efforts or designing high-capacity bridge foundations, the team looks at the individual system pieces — technical, environmental, constructability, schedule, and community — to understand the complete picture and deliver solutions that address each component. Spanning airports, federal government, ports, harbors, and coastal infrastructure, state and local government, and transportation, infrastructure engineering consultants go beyond task-based and cookie-cutter approaches. Working alongside clients to examine big-picture objectives — including sustainability goals — integrated innovation and advocacy result in reduced overall costs and the ability to get more done with less effort or investment.

Industrial and manufacturing consulting

Looking through a different lens so manufacturers can do more with less, improve business performance, and mitigate risks — the industrial and manufacturing consulting team gains a deep understanding of the near- and long-term environmental and manufacturing challenges across the business lifecycle, co-creating innovative solutions that secure clients' futures. Sub-markets served include Automotive, Consumer Products, Food and Beverage, Manufacturing, and Metal foundries, finishing, and recycling. Today's industrial and manufacturing companies operate in a highly competitive business landscape marked by ongoing change. As environmental, regulatory, social, and community pressures mount, the team finds and develops solutions to help future-proof businesses — from legacy site cleanups that reduce costs and lessen environmental liability, to novel in-situ subsurface site characterization tools, out-of-the-box risk assessment applications, and remote sensing devices to collect visual data.

Mining consulting services

Delivering value to stakeholders so mining clients can succeed — business success for mining operations hinges on productively partnering with governments, agencies, community advocacy groups, and non-government organizations. As passionate advocates for the mining industry, the team participates in industry associations, decision-making bodies, and community organizations that have the most impact on projects. Mining projects must navigate complex permitting processes, evolving environmental regulations, and collaboration with local communities across abandoned mine lands, aggregate and construction materials, base and precious metals, and industrial and critical minerals. Mining consulting teams work alongside internal groups and stakeholders to minimize obstacles and find win-win solutions for clients, regulators, and the communities in which they operate.
