Flown low and slow with a high-resolution camera, giving a model detailed enough that small setting-out errors show up clearly instead of disappearing into the noise.
The survey is tied to your project control rather than a national grid, so the model lands in the same coordinate system your site engineers are already working in and nobody has to convert anything.
Progress, not just geometry
Repeat captures on the same plan give you structure-by-structure progress, temporary works and material staging on a common frame. Every survey is comparable because every survey is flown identically.
What it will not do
An aerial capture sees the top and the outside. Undersides, service voids and anything beneath a completed slab need a ground-based scanner, and we will say so rather than sell you a flight that cannot answer the question.
