Lot-by-lot grade verification
Lot Viewer checks every pad against design grade using the drone scan you already have — cut/fill balance, nine spot elevations, and a tolerance flag on every lot. Send the dirt crew where dirt is still needed, and the survey crew only where certification will pass.

The problem
Pads get called in by feel — a walk-through, a phone call, whoever was on site last. The crew mobilizes, the lot fails certification, and the loop starts over. The vertical start date does not move with it.
A pad two tenths of a foot high fails certification. You pay for the trip, the rework, and the trip back — and the same crew gets called out six or seven times on one phase.
Without per-lot quantities, contractors work from memory. Balanced lots get touched, over-filled lots get missed, and nobody can point to a number.
The superintendent knows which lots are close. The PM managing seven projects from two hours away does not, and neither does the civil engineer or the dirt sub.
Cut / fill balance
The moment a scan processes, every lot gets a color. Red needs cut, blue needs fill, white is balanced. Zoom in and each lot carries its own cubic-yard number, so the dirt contractor gets a quantity instead of a hand wave.

9-point spot elevations
Lot Viewer pins up to nine elevations per lot — the lot corners, the building pad, and the center — and prints the design elevation and the difference right beside each one. It is the same check a crew would walk, without the walk.
Deviation & tolerance
Enter the maximum acceptable deviation from design grade and Lot Viewer highlights only the lots outside it. Everything else drops back, so the crew works the lots that actually need correction instead of re-walking the whole phase.

Relying on surveyors for something as simple as an elevation check is inefficient and a quick way to run through budget.

See Lot Viewer at work on a 500-lot demo site — turning on cut/fill, setting a deviation tolerance, reading nine spot elevations on a pad, and exporting the failing lots for the dirt contractor.
From the field
“We use Lot Viewer on all of our projects, and it’s quickly becoming our favorite tool within TraceAir. It allows our teams to pinpoint exactly which lots require attention and the specific areas in need of adjustments. This not only minimizes additional surveying expenses, but also accelerates project timelines overall with cleaner lot handoffs from site work contractor to vertical production.”
Garth De Blasio, Manager of Land Development, Mungo Homes, Raleigh Division
