Volumetric Surveys: verified survey data and clear outputs for confident design, planning and delivery decisions.
Volumetric surveying answers the question: 'How much material is there?'. Whether it's a stockpile of aggregate or a massive excavation, estimating by eye is costly and risky.
We use drone photogrammetry or laser scanning, as appropriate to the site, to capture the visible surface of the material. Volumes are calculated relative to an agreed base surface or compared with a previous survey using a consistent reference.
A documented volume report helps teams compare material quantities and track change. Agree the base surface, survey dates, calculation method and intended commercial use so comparisons are meaningful.
Volume calculations depend on the surveyed surface, control, coverage and defined base. The capture method and verification requirements are agreed around the intended use and site conditions.
Reports state the base surface, survey dates, calculation method and relevant limitations. If a volume-to-mass calculation is requested, material density or compaction factors supplied for the project are documented separately.
A verified workflow for volumetric surveys data capture.
Survey the surface using drones or laser scanners.
Create a 3D terrain model of the material.
Compute volumes relative to base levels.
Deliver volume certificates and heatmaps.
There is no universal percentage accuracy for a volume survey. Uncertainty depends on capture, control, coverage, base-surface definition and site conditions. Agree the required uncertainty, checks and intended use before commissioning.
We measure the bulk volume. We can apply expansion/compaction factors if provided by your engineer.
Yes, we use laser scanners for indoor stockpiles where drones cannot fly.
