Reality Capture / Volumetric & Stockpile Analysis
Eagle Surveying measures defined surfaces and reports geometric quantities for stockpiles, cut and fill, excavation, material inventory, and change over time. Depending on the project, collection may use aerial photogrammetry, LiDAR, conventional surveying, or a combination tied to project control.
Measured cut, fill and volumes
Defined base surfaces
Change tracked over time
Overview
Volumetric analysis compares a measured surface to an agreed base, prior surface, or design surface. The result can be used to report stockpile quantities, cut, fill, net change, excavation, or other defined geometric volume measurements.
The calculation is only as useful as the basis behind it. Measurement limits, comparison surfaces, project control, collection date, and assumptions all matter.
Surfaces are tied to survey control and may be checked with independent ground verification/check shots—sometimes called ground truthing—based on the required accuracy, site conditions, and scope.
Measure a defined pile, material yard, or inventory area against the agreed base surface and measurement limits.
Compare the current measured surface to a prior or design surface to report cut, fill, net change, or other agreed quantities.
Repeat collection using a consistent basis so project teams can compare measured surfaces as earthwork or inventory changes.
Measurement Basis
A volume is not just a property of the pile or the site. It depends on the measured limits and the surface used as the basis of comparison.
Shrink, swell, compaction, and other material-conversion factors are not determined by Eagle Surveying. Those factors are applied by the appropriate owner, contractor, estimator, engineer, or other project party.
Collection
Eagle selects the collection approach around site conditions, required coverage, project control, and the final measurement — not around one piece of equipment.
Well suited to large, open areas where visible surface conditions and high-resolution aerial imagery support the required measurement.
Used when terrain, vegetation, site conditions, or the required surface information make LiDAR the more appropriate collection method.
Supports project control, verification, targeted measurements, and areas where aerial collection is not the right tool.
Volumetric work is most useful when the project team needs a defensible measurement basis — not just a picture of the site.
Measured quantities for large grading, excavation, and fill operations.
Aggregate, soil, sand, and material inventory for contractors and operators.
Supporting quantity information for subcontractor review and pay-application documentation.
Comparison of current measured conditions to an agreed design surface.
Repeat measurements for operational, financial, or project reporting.
Measured existing-condition data that can support earthwork estimating and project planning.
Deliverables
Not every project requires the same files. Eagle scopes the reporting and supporting data around the measurement, downstream use, and client requirements.
Measured geometric volumes for the defined stockpile, area, or surface comparison.
Calculated cut, fill, and net change based on the agreed measurement limits and comparison surfaces.
A georeferenced overhead image may be included when aerial imagery is part of the collection workflow.
Digital surface information may be provided when it is part of the agreed scope and useful to the project team.
Example measured stockpile surface and volume calculation.
Direct access when it helps the project team.
Repeat surface comparisons and hosted project access can be included when the assignment calls for ongoing review.
When included in the scope, Eagle can host applicable project data in DroneDeploy for client access and review of available project information and surfaces over time.
Volumetric and stockpile surveys use measured surface data to calculate cut, fill, net volume, stockpile quantities, or changes between surfaces. Eagle Surveying can collect the surface with aerial photogrammetry, LiDAR, conventional surveying, or a combination of methods. The resulting volumetric data supports earthwork tracking, material inventory, existing-versus-design comparisons, progress review, and quantity analysis.
