The firm delivers projects from initial feasibility studies through design, construction supervision, and facility management, supplemented by proprietary software products (Kalypso, KalypsoForecast) and the INKA trenchless pipeline construction service line. It serves both public sector clients (municipalities, government agencies) and private sector clients across Germany and selected international markets.

The company offers a comprehensive portfolio of engineering consulting services organized into six core divisions: Water, Environment, Civil Engineering, Informatics, Energy, and Architecture. The product portfolio includes specialized software solutions (Kalypso Modeling System and KalypsoForecast for flood forecasting and water resources management), and the INKA product line for trenchless pipeline construction innovation with four sub-products (OLC for real-time load monitoring, VAL for value engineering, Pro for procurement, and Exe for execution supervision).
