The firm’s service portfolio is built around proprietary methodologies — the 360° Consulting approach, Cradle to Cradle design principles (via EPEA), and Lean Design/Site Management — alongside digital delivery tools such as Building Information Modeling. It also operates the Blue Waves podcast and maintains a dedicated Claims and Expert Services practice for construction dispute management. Customers span real estate developers, healthcare providers, semiconductor and industrial manufacturers (imec, Salzgitter Flachstahl, Kedali, DPG Media, Hôpitaux Kirchberg, Aeroporto di Bologna, Unipol Dome), and government/municipal housing entities.

Go-to-market is partner-led and relationship-driven through 80+ regional offices across 20+ countries in Europe, the Middle East, Asia-Pacific, and North America, supported by sector-specific account managers and thought-leadership channels (MIPIM, Blue Waves, LinkedIn, Instagram).
