Construction and grading · Sample report
How much dirt is left? A fast answer.
Send the design file and a recent flight. We'll send back what's done and what's left.
“we would be really limited in the amount of surveys that we'd be able to do because of the time it took we normally would maybe only do a beginning survey and then a survey at the end and that's it and no real production tracking in between”
“the lidar surveys we've used in the past are typically very expensive and it takes a lot of time to get those done a particular lidar survey may take up to a month to get the data results and we would like something more real-time”

01The problem
Dirt moved per day is the number that matters, and a crew day is expensive. Your graders trust machine control, so the surfaces and CAD have to load straight into it.
02What you get
- 01A one-pad progress check from data you already have: existing ground, the design surface and a recent flight.
- 02You get cut and fill done, cut and fill left, percent complete and a heat map.
03How close the tool gets
On the test site, remaining cut came within 0.2% of the known answer and total cut and fill within 0.5%. Cut complete read 36.6% against a true 36.5%.
Checked on test sites where the true answer was known. Not a promise for your site.
04When you need more
Monthly pay-application quantities (grading vs design), fast-turnaround takeoffs on request, and machine-control-ready surfaces through a PLS partner.
- Quantities are in-place (bank) volumes with no swell or shrink applied. Use your own factors.
- Pay quantities are a progress estimate. Final pay quantities and any regulator submittal are sealed by a PLS/PE.
- Vegetation, equipment and stockpiles left in the ground class read as fill.
