At the forefront of green and sustainable remediation, our innovative thinking and turnkey solutions have been applied successfully to thousands of industrial, mining, development and hazardous waste sites around the world. We have established an unsurpassed reputation with both public- and private-sector clients and regulators around the world for achieving cost-effective site closure.

Site investigation

Ramboll has extensive experience developing and implementing comprehensive site evaluations. We harness a complete range of field services to identify the nature and extent of substances of potential concern in soil, sediments, surface water, groundwater and building systems. Our tiered, risk-based approach ensures focussed, cost-effective site investigations. Our skills in collecting, interpreting and managing site data complement our capabilities in fate and transport modelling and health risk assessment, enabling our investigators not only to evaluate the current status of site contamination, but also to provide valuable input into the development of site-specific, risk-based remediation goals.

Site-specific risk assessment

We draw on experts in the toxicological, biological and physical-chemical principles underlying the risk assessment process, as well as on experts in conducting exposure assessments, enabling us to apply innovative, scientifically defensible risk assessment and management to:

  • Optimise the scope of work for site investigations
  • Quickly and conservatively identify potential problem areas and provide early estimates of the nature and magnitude of problems
  • Reduce unnecessary data collection
  • Focus efforts where the greatest gains in risk reduction can be achieved

Remedy evaluation, design and implementation

Ramboll's interdisciplinary approach to site remediation helps clients manage the complex and interrelated issues that drive remedial decisions. Reflecting our commitment to be at the forefront of remediation technology, we are integrally involved in a valuable innovation in site management – sustainable remediation. When engineering a solution, we consider ultimate site risk-reduction goals, risk management during implementation, management of long-term risk and future liabilities, and the short- and long-term costs of various alternatives. We have applied formal decision and probabilistic cost analysis techniques to consider the effects of uncertain cost components on the overall cost of alternative remedies.

Remedy optimization and sustainable solutions

Remediation strategies for site closure have undergone a significant paradigm shift. Once the exclusive domain of energy-intensive, mechanically driven processes, passive strategies such as in situ bioremediation, chemical oxidation and chemical reduction are emerging as integral remediation tools. The growing use of remedy optimisation strategies and innovative diagnostic tools is advancing these processes to facilitate more rapid site closure. Ramboll integrates our experience with streamlined risk assessment methods, conventional and innovative remediation design, process optimisation and diagnostic tool development to achieve cost-effective remedies leading to faster site closures.

Net environmental benefit analysis (NEBA)

NEBA demonstrates the positive and negative impacts on natural resource services associated with a remedial action relative to the incremental changes in risk. In some cases, for example, a proposed remedial action or reuse alternative may destroy or significantly degrade the ecological landscape, yet achieve little or no reduction in ecological or human health risk. In simpler terms, a NEBA can be used to determine, for each alternative considered, whether the detrimental impacts of the remedy outweigh the benefits.

Construction management

We provide construction management services – including remediation, decommissioning, decontamination and demolition – for the implementation of a variety of projects. Our experts assist in the preparation of specifications, manage the bidding process, negotiate and administer contracts, schedule construction, supervise implementation on site, and assure compliance with specifications, budget and schedule. We can provide these services in a traditional construction management role, in the role of designer/builder or through turnkey delivery of an entire project. For each engagement we provide a dynamic team of experts to meet the client’s requirements on time and within budget.

Brownfield redevelopment

Ramboll develops cost-effective, risk-based approaches to the evaluation, remediation and redevelopment of landfills and former industrial or hazardous waste facilities to return the land to productive use. We work with site developers to find the optimum approach to managing soil and groundwater risks in the context of the proposed land use, and have successfully negotiated these integrated risk management strategies with regulatory agencies. Our sustainable approach to brownfield redevelopment plans provides long-term economic and socioeconomic benefits for the client and the community.

Site decommissioning and demolition

Site decommissioning and closure is a complex, highly regulated process. Ramboll works with clients to manage the process of decommissioning sites to mitigate risks to the environment, while also attaining the best value for the plant, equipment and the land itself. We assist with tender document preparation, supervision of site decommissioning work, and preparation of supporting information to achieve regulatory closure.

Expert services

Ramboll provides consulting services, expert testimony, strategic advice and technical litigation support to clients. We have worked on many seminal environmental, toxic tort and product liability cases. We recognise the importance of well-reasoned expert opinions based on defensible science, rigorous analysis and an intimate understanding of environmental practice, policy and regulation.
