Drone mapping and inspection, flown by the engineer
FAA Part 107 aerial photos, progress records, and measurements from a DJI Air 3S, flown by the engineer on the project and used directly in the design and the inspection record.
Flown by the engineer, not a subcontractor. The aerial data goes straight into Civil 3D and into the daily report, which is the point: one visit, one flight, and the roof frame, the trench, or the site overview is on record the same day. No handoff to an outside operator and no waiting on someone else's deliverable.
What we use it for
- Progress records
The same waypoints flown on every visit, so photos compare frame to frame and disputes settle from the record.
- Inspection angles a ground camera cannot reach
Trench depth and bedding from above, roofs, facades, the far side of a stockpile. The 70 mm medium telephoto camera does the close work without a ladder or scaffold.
- Measurements for design
A square-on elevation at eave height, a roof plane for a tie-in, a site overview to lay out a utility corridor.
- Mapping
Orthomosaics and photogrammetric surfaces for planning and design use. Where boundary or control-grade topographic survey is required, we coordinate with a licensed land surveyor.
- Volumes
Stockpile measurement and cut and fill estimates from photogrammetric models.
- Stills and video for the record
50 megapixel stills and 4K HDR video for project files, reports, and presentations.
From real projects
Every frame below was captured on an Aligned Engineering job and used in the engineering that followed.
