Real Estate, Insurance, and Finance

Geosyntec helps clients realize successful property transactions and site development projects. We understand the physical challenges and environmental compliance issues associated with achieving the full potential of a property.

Whether we are redeveloping contaminated properties, addressing subsurface vapour migration, or identifying landform improvements that can improve the functionality of the property, Geosyntec practitioners support clients as they address complex challenges. We also provide assistance to developers in auditing compliance, navigating regulations, developing audit protocols, and conducting audit programs.

Clients choose us for our extensive experience and expertise in due diligence for property transactions, property valuation, and cost-to-cure estimates for environmentally impaired properties. We evaluate environmental impacts to help identify, select, and purchase sites for redevelopment, and we provide technical support through the brownfield's designation process. We incorporate risk-based approaches and end-use planning to develop best-value remedial strategies to mitigate environmental and financial risks for our clients.

Our capabilities are far-reaching—domestically and abroad; our partnership with CAT Alliance ( provides an expanded network of over 10,000 professionals across over 50 countries to support clients in all aspects of due diligence from single-site transactions to large-scale portfolios in complex stock or asset deals.

Founded in 2001, CAT is a joint venture among three leading consultancies—COWI (Scandinavia and Eastern Europe), Geosyntec (North America, the United Kingdom, Sweden, and Southeast Asia), and Tauw (Southern and Western Europe). The alliance provides environmental due diligence to support large industrial, commercial-property, and financial clients. Specializing in corporate asset and transaction support, CAT has conducted environmental due diligence for more than 20,000 properties and has helped clients identify and recognize more than $100 billion in potential environmental liabilities as part of corporate transactions.

Our work with landforming techniques such as mechanically stabilized walls and low-impact development allows site planners and architects greater freedom in achieving aesthetic, Leadership in Energy and Environmental Design (LEED), and site-use objectives.
