Construction Progress Monitoring
The same site measured repeatedly, so you can see change rather than hear about it. Volumes moved, areas built, drainage installed, and a defensible record of progress against the programme.
Typical accuracy · ±2% on volumes to a stated surface, provided surfaces are not obscured.
When you need it
- →You are paying for work by stage and need to verify it was done.
- →Volumes of spoil, aggregate or excavated material need measuring.
- →You want to monitor a site without visiting it every week.
- →A contract requires periodic measurement for valuation purposes.
What you get
- Periodic volumetric comparison between epochs
- Site photography from consistent angles
- Cut and fill and stockpile volumes
- Progress against programme with variance noted
- Full point cloud archive for every visit

Questions we get asked
How often should we monitor?
Monthly suits most valuations. Weekly makes sense for fast earthworks or a dispute. We will tell you if the interval you want will not produce useful data.
Often needed alongside
Volumetric & Stockpile Surveys
Instant stock tonnage, cut and fill volumes from measured data.
As-Built & Completion Surveys
Final measured records for handover and compliance sign-off.
Drone Photogrammetry
Aerial reconstruction producing accurate 3D models and imagery.
Volumetric & Stockpile Surveys
Instant stock tonnage, cut and fill volumes from measured data.
