Illustration Construction · Idaho & the Intermountain West
Document the build. Defend the draw.
Recurring aerial documentation of construction progress for general contractors, owners and lenders. The same site, the same frame, on a fixed cadence, so two dates can be compared rather than argued. You receive a dated orthomosaic, a change overlay against the prior capture, a photogrammetric model and a volumetric report.

Stakes
The argument is always about what was there, and on what date.
A site is photographed constantly, by the superintendent and by every subcontractor. None of it shares a position, a scale, or a date you can defend. Thousands of images, and no two you can set side by side to state what changed.
What changes when the record is dated and registered.
Argued
On the record
the owner maintains only 40% was done and pays accordingly
- A dated orthomosaic in the same frame as the last draw. Percent complete is read off a record instead of argued across a table.
i found that taking digital pictures of my work that will be buried in the wall is good insurance
- Systematic dated capture before concealment, in one archive the contractor, the owner and the lender all cite from.
- As-designed grades rarely match field conditions, and quantities are hard to establish from ground level.
- Photogrammetric surface comparison between captures for cut and fill at each milestone, supplied as documentation.
Why the second flight matters more than the first
Comparable beats numerous.
The baseline flight fixes the route, the altitude, the overlap and the camera settings, and saves them. Every capture after it repeats them exactly. That is the whole difference between a folder of photographs and a record.
Because the captures are geometrically comparable, the change between two dates can be measured rather than recalled. A volume, an area, a completed elevation. Every flight becomes your baseline, so the next one shows what changed.
- New since the last capture
What you receive.
- GeoTIFF 01 Dated georeferenced orthomosaic The site from above on a known date, to a known scale, measurable for length and area.
- PDF 02 Change overlay This capture against the prior one, with what moved called out.
- OBJ + DSM 03 Photogrammetric 3D and surface model Reconstructed from overlapping imagery, for volumes and as-built comparison.
- CSV + PDF 04 Volumetric report Cut, fill and stockpile quantities, computed between captures.
- JPEG 05 Timestamped photo archive Every frame GPS-referenced and dated, issued to the whole project distribution list.
- PDF 06 Progress record Dated and keyed to your schedule-of-values lines, for the lender’s draw file.
How a job runs.
- 01 Scope Site boundary, cadence, distribution list, and what the record has to satisfy.
- 02 Baseline First flight fixes route, altitude, overlap and settings, and saves them.
- 03 Cadence Later flights repeat the saved route; conditions and deviations recorded.
- 04 Compare Each capture processed, overlaid on the prior one, issued to the team.

A short call fixes the site boundary, the cadence, and what the record has to satisfy. The first flight becomes the reference the next one is measured against.
