Autonomous construction site monitoring

  • One analytics platform: drones, robotics, BIM and AI.
  • The technical scenario end to end — from the survey flight to the readiness report.

03 / Stage 1

The aerial survey creates a digital replica of the site

Automated drone flights along pre-planned routes continuously produce an up-to-date copy of the site.

01Photogrammetric capture and an orthomosaic of the site.
02An up-to-date 3D model rebuilt on every flight.
03Oversight of machinery and personnel across the site.
04Cloud data transfer in real time.

Robotic inspection of enclosed areas and covered works

Once the survey flight is done, the platform performs deep scanning of the interior using LiDAR, HD cameras and autonomous positioning algorithms.

  • Quality control of covered works.
  • Stocktaking of construction materials in storage.
  • Detection of deviations from the drawings.
  • Autonomous navigation inside the building.

Matching physical reality against the design BIM model

The captured as-built data is overlaid automatically onto CAD drawings and the works schedule.

01Actual volume of completed work.
02Quantity of materials consumed.
03Deviations from design parameters.
04Adherence to the construction schedule.

Neural networks classify objects and flag violations

AI algorithms analyse the visual data to generate analytical reports automatically.

  • Calculation of poured concrete volume.
  • Counting of installed elements and assembled structures.
  • Logging of construction defects.
  • Detection of safety violations.

08 / Volumes

Volumes and materials are calculated from the digital model

01Earthworks calculation: cut and fill are measured from the model, with no surveyor walking the pit.
02Stockpiles: the volume of spoil heaps and material piles on site.
03Change over time: comparing surveys shows the output for the period.
04Reconciliation: actual volumes against what the contractor has claimed.

Automated control cuts risk and cost dramatically

−80%

Time spent inspecting the site. A survey flight instead of walk-rounds and manual measurement.

24/7

Digital twin refresh. Daily, with nobody on site.

100%

Transparency. For the client, the contractor and the investor.
