Measured twice, compared against the order, before anything is cut.

✓A pre-quote survey starts empty — the surveyor adds openings as they find them
✓A production survey is populated from the confirmed order and refuses to start without lines
✓Each has its own numbering, its own report, its own approval, its own mobile app
✓A production survey can be seeded from the pre-quote instead of from scratch

✓Quoted width, height, area and quantity beside the measured ones, per opening
✓Width, height, area and quantity differences, and a pass/fail per item
✓A survey outside the configured tolerance goes to a manager instead of to the saw
✓The surveyor is warned on site, before they drive away

✓A portal login, not an ERP seat
✓Bluetooth laser meters — Leica DISTO, Bosch GLM, Stanley TLM and generic BLE
✓Photos per opening, GPS on start and finish, and a signature with the signer’s capacity
✓Saves queue on the handset and replay in order when the signal comes back
✓A tappable elevation drawing to move between openings

✓The survey line carries its own drawing, independent of the one the customer signed
✓Editing it re-runs the take-off against the measured sizes
✓The original stays visible beside it, so the change is reviewable

The numbers on the wall

The Technical control tower: completion rate, open requests, surveys done against surveys booked, workload by person, and requests by type. Survey reporting adds surveyor performance and monthly statistics as pivots.
