Make construction ready for a more productive future.

Digitization can be a very powerful tool in that but there is one blank spot – the construction site itself.

Contakt - Your Site in Sync.

Contakt is a methodology and digital toolset to increase building productivity.


Digital Construction Intelligence
Your simple approach to increase building productivity with Collaboration Apps, Internet of Things, Big Data and Artificial Intelligence.

Digital Construction Site

Increase site productivity.

  • Digital Twin of the construction site, BIM-compatible.
  • Site management tool for site managers and foremen: site planning (process, teams, materials), collaboration and execution.
  • Sensors to deliver additional as-is real time data.
  • BIM compatible.

A significantly (6 - 15 %) more productive construction site with proactive execution of teams, material flows and workflows.

The site monitoring tool

Site transparency increases efficiency.

  • Real-time monitoring of the building progress for construction companies, building owners, developers and planners.
  • As build documentation.
  • Early detection of delays and problems.
  • Proactive action to save construction time and costs.
  • Finance and risk management through transparency.

Higher margins: improved competitiveness, risk management and best-practice construction execution.

Learning Construction Process

Construction Process Improvement.

  • Build up of big data - Data analytics and artificial intellligence.
  • Identification for waste reduction potentials for lean construction.
  • Learning construction process - AI defines best practices for future projects.
  • Sound data for upcoming projects, e.g. calculation, work preparation, simulations.

Higher margins: more knowledge in pre-development, transparent risk management and transparent execution.
