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.

Digital Construction Site

Digitize the site and boost productivity.

  • Optimize the building process with a takt planner app for site managers and foremen: site, team & material planning, collaboration and execution.
  • Get field data from the site: IoT/sensors to deliver additional as-is real time data. BIM compatible.
  • Digital twin - Transparency makes it possible to identify potential for improvement.

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

  • 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

The best process through data insights.

  • Build up of smart data - Data analytics for a sustainable increase in productivity and margin.
  • Identification of waste reduction potentials for lean construction.
  • Sound data for upcoming projects, e.g. calculation, work preparation, simulations.
  • Learning construction process - Derivation of best practices for future projects.

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