For a developer, control.io is an independent check on what the main contractor reports. A drone flies each site on a fixed cadence, the flight is rebuilt as a 3D model, and the model is compared with the programme so you see, per floor and per trade, whether the building is where it should be on that date.

Problems and answers
Independent proof of progress for buyers, boards and investors, without waiting for the contractor's monthly report.
- 01
The problem
Progress reports come from the contractor whose performance they describe.
With control.io
Drone measurements are taken by a third party and the raw imagery is kept, hashed, for anyone to re-check.
- 02
The problem
Buyers and investors ask for updates the site team has no time to prepare.
With control.io
Share a read-only live feed or a branded PDF after every flight, generated without site-team effort.
- 03
The problem
Slippage becomes visible only when a handover date is already lost.
With control.io
Per-trade day counts flag a floor as 'watch' weeks before it becomes a critical delay.
Deliverables
- Monthly or bi-weekly drone flights on a repeatable route
- 3D model and orthomosaic for each flight
- Floor-by-floor progress verdict against the programme
- Investor-ready PDF report with image evidence
- Read-only live dashboard for buyers and partners
Does control.io replace the contractor's progress report?
No. It sits beside it. The contractor still reports; control.io gives you an independent measurement so you can tell when the two disagree.
Can I show the dashboard to apartment buyers?
Yes. You can publish a read-only view per project, limited to imagery and high-level progress, without exposing commercial documents.
How often should a residential tower be flown?
Monthly flights suit most structures. During frame and envelope, when floors change quickly, bi-weekly flights give a clearer trend.
