Since 2012, legislation in France has had a major impact on utilities operations — and there’s no sign of it slowing down anytime soon.

Over the next decade, more and more utility networks will gradually have to be georeferenced with a high degree of accuracy. Essentially, every time installations or repairs are needed on an underground utility network, networks must be georeferenced first.

Bringing in a surveyor-topographer to survey the network can be expensive and slow down the project timeline.

But with FOUILLES 3D (F3D), a comprehensive solution from Hexagon partner Geosystems France, civil engineering teams can handle the task themselves. Built with Hexagon technology including M.App Enterprise and Leica GG04+ GNSS antenna, F3D lets users conduct open trench surveys and create reports fully autonomously.

F3D assists both onsite and office users.


  • An operator walks alongside the open trench with the F3D “pistol” and records the data.
  • Survey data from the network is transmitted to the processing platform.
  • The operator receives a report in minutes, validating that the survey is safe to continue.

In the office:

  • The manager also receives the survey report and can check the quality of the onsite team’s work.
  • The manager can access the data to draw a CAD plan and can also receive data to analyze the onsite team’s other activities.

F3D offers a greener, easier, faster, and cheaper alternative to bringing in a specialist to conduct the surveying, and users can also expand its capabilities with an add-on for stakeout, marking/picketing, and detection. Another add-on that includes augmented reality to visualize utility networks in real time.

Watch how simple it is to use F3D:
