Construction & volumes

Measure quantities instead of estimating them. By drone, at a fixed price.

We survey stockpiles, excavations, landfills and entire sites from the air. You receive volumes, an elevation model and an orthophoto as a report and in the online portal, reliable for stocktaking and billing.

The result

A report for the file, a portal for the work.

The PDF report documents the quantities. In the portal, our MapApp, you can measure for yourself: new reference surfaces, partial quantities, elevation profiles, without buying software.

  • Volume, fill and cut against selectable reference planes
  • Comparison of several flights for stocktaking and progress
  • Elevation profiles, contour lines, areas and distances
  • Download as GeoTIFF, LAS/LAZ, GeoJSON, shapefile and PDF
  • A separate instance per customer, hosted in Germany

Who it is for

Where the drone pays off.

Gravel, sand and recycling

Stock levels on the reporting date, one to four times a year, compared with the previous state.

Earthworks and demolition

Excavation, fill and soil heaps as evidence for billing, before and after the work.

Landfills

Fill level, remaining capacity and settlement from repeated flights.

Remediation and ordnance clearance

Planning basis, documentation of each work step and quantities for billing.

Planners and surveyors

A full-coverage terrain model to complement ground surveys, also as a subcontractor.

Developers and municipalities

Construction progress at fixed intervals, traceable for everyone involved.

References

Proven in remediation and clearance.

We supported seven projects for Nolte Services, flying one site three times. For WESSLING we captured a site in Cologne for BASF in 2026. Each included mapping for planning, monitoring during the works and earthwork quantities for billing.

FAQ

Short answers.

How accurate is the measurement?

We fly with RTK correction and use surveyed ground control points where needed. Position and height are accurate to the centimetre range. The report states the accuracy achieved.

How fast is the result available?

Usually a few working days after the flight. For simple surveys, capture, processing and delivery are possible on the same day.

Do operations have to stop for the flight?

No. We fly above ongoing operations and do not walk on stockpiles. We arrange permits and coordination in advance.

What do you need for a quote?

The address or a site plan, the approximate area and the purpose of the measurement. You receive a fixed-price quote.

Can we use the data in our own software?

Yes. All results are available for download in common formats and can be used in GIS and CAD.

Which quantity should we document for you?

Tell us the location and area. You receive a fixed-price quote.
