Overview
Project overview
Construction conditions on this custom home changed quickly as framing, roof geometry, and rough-in advanced. The documentation objective was to preserve a repeatable 3D record of those conditions so the project team could review progress without reconstructing the site from disconnected photographs.
Each capture produced a navigable model that could be compared with earlier visits. The record supported remote review, coordination, and later confirmation of what had changed.
Deliverable
Interactive 3D model
Orbit and zoom the reconstructed geometry. Viewer measurements are useful for planning; record drawings remain with survey or engineering when those are required.
Objective
What needed to be preserved
- Framing and roof geometry as work advanced
- Openings, chases, and rough-in context
- A comparable 3D record between visits
- Remote review of changing construction conditions
Methods
Capture method
Aerial photogrammetry used overlapping stills around the structure, then processed those stills into a 3D model. Repeat visits used comparable camera geometry so later models could be compared with earlier ones.
When RTK or other positional control is used, it can improve alignment between visits. Alignment still depends on capture conditions and the control method specified for the engagement.
Why it mattered
Progress visible after the site has changed
Once sheathing, wrap, or interiors proceed, earlier geometry is no longer available on site. A dated 3D record keeps that state reviewable.
Technical considerations
Each model preserves visible construction geometry at that visit. Concealed work, interiors after enclosure, and dimensions outside the capture are not established by the model. It is a progress record, not an as-built survey.
