Volumes that survive the audit.
A volume number is only as good as its methodology. Every Nexus report ships with the ground control, the surface used, and the algorithm — not just the answer.
Stockpile inventory
Per-pile volume, tonnage (with material density), and footprint. Fits monthly inventory cycles for aggregates and bulk-material yards.
Cut/fill against design
Compare current ground to the design surface — net cut, net fill, balance per zone. Driven by your DXF or LandXML.
Haul-route earthworks
Mass-haul progress for road, pipeline, and rail corridors. Quantities by station.
GCP-tied accuracy
Surveyed ground control on every flight. Sub-cm horizontal, < 3 cm vertical.
Audit packet
Methodology PDF, raw point cloud, and the CAD surfaces — everything a third-party reviewer needs.
Period-over-period
Stack monthly captures to track inventory drift, not just a single snapshot.
Numbers, plus the work behind them.
A volume report is one of seven deliverables — the rest are the evidence.
