Construction As-Built Services

Construction as-built services document the actual conditions of a site or structure at a specific point in time, providing a factual record of what was installed and where. By incorporating drone-based data capture, 3D Flight Maryland enhances traditional as-built documentation with high-resolution aerial mapping and visual verification that would otherwise require multiple site visits or manual inspection. This approach improves accuracy, reduces time on site, and produces reliable records that support quality control, project closeout, compliance, and future construction planning.

The four images above show the process:

1. The black-and-white Ground Control Points (flags) are placed at known on-site locations. Then we fly the drone to capture many straight-down photos, which are combined into a single aerial orthomosaic image.
2. We measure the coordinates of the Ground Control Points onsite. The points allow us to align the aerial image with the on-site surface elevation.
3. We identify the same known points in the building plans.
4. Finally, we combine the aerial image and building plan using Ground Control Points, and the building plan is now matched to the actual site conditions.

Overlaying the building plan will show whether the onsite implementation matches it. If not, you can quickly correct it before it becomes expensive.
