Construction and tunnelling
Existing conditions, progress and as‑built, above and below ground.
Existing conditions before design, volumes and progress during the works, and as‑built against the design model at handover, above ground and below. Each repeat survey is aligned to the last and graded point by point against the surveys' agreement on stable ground.
- 13.2 mm · held-out median mismatch between two survey campaigns · Satsop
Registration agreement between scans, not absolute accuracy against control.
