Sewerage survey (hydronaut study) by INVAR surveyors

As-built measurements

Buildings, sewerage works, roads, etc. Many projects require an as-built measurement afterwards. INVAR Landmeters is your permanent point of contact for as-built measurements of:

  • roads
  • sewers
  • probings
  • test trenches
  • buildings

As a progressive surveying office, INVAR also deploys drones for as-built measurements. Your as-built plan also allows you to compare areas, lengths, etc. with the bill of quantities. With the right information, you can complete your project smoothly. 

GRB in accordance with asbuilt plan by INVAR surveyors

Large-scale Reference File (GRB)

The GRB digitally maps Flanders in a uniform way. This basic map contains roads, plots, watercourses, but also lighting posts, manhole covers and coping stones. As-built files are required to be drawn up in the GRB structure. At INVAR Landmeters we have the necessary expertise to carry out this according to the rules of the art.

In places that are difficult to reach, we can also use photogrammetry to supplement the as-built plan. 

Engage us for your as-built files in GRB.
