Earthworks & Volume Surveys
Stockpile, cut-and-fill and progress volumes measured properly — defensible numbers for payment, planning and inventory.
Earthworks money moves on measured quantities. PCI Surveys measures stockpiles, excavations, embankments and progress volumes using drone photogrammetry, LiDAR and ground survey, then computes quantities against design surfaces, previous surveys or base models — so payment applications, inventory counts and haul planning stand on defensible numbers.
Drone-based volume surveys let us measure large or active sites quickly and safely, without walking crews across stockpiles or live equipment areas, across BC, Alberta and the Yukon.
What PCI Performs

PCI In The Field
Real crews. Real sites.






Common Questions
Earthworks & Volumes FAQs
How are cut/fill and stockpile volumes calculated?
We measure the surface — by drone or on the ground — and compare it against a base surface or design surface. The difference is your volume, reported clearly.
Why measure volumes by drone?
A drone captures the entire surface in one flight — denser data than ground shots, no climbing on stockpiles, and repeat flights make month-over-month comparisons easy.
How often should stockpiles be measured?
Whatever your reporting cycle needs — monthly or quarterly inventory, pre- and post-project, or at billing milestones. Repeat flights are quick once control is in.
Can the numbers be used for billing and inventory?
Yes — flown with ground control and validated against checkpoints, volume reports are built for quantity reconciliation and inventory reporting.
