To track construction progress with drones, capture the site on a fixed cadence, turn each capture into a measurable twin, compare it against the previous capture and the design, and share the result through a portal. Done well, it replaces site-visit guesswork with a time-stamped, defensible record.
1. Set a capture cadence
Pick a rhythm that matches your reporting — weekly or fortnightly for active builds, monthly for slower phases. Consistency is what makes comparison meaningful: the same coverage every time means every change is real, not an artefact of coverage.
2. Build the twin
Each capture becomes a survey-grade twin — orthomosaic, terrain and 3D exterior, plus interior walkthroughs pinned to floor plans. Because it's geo-referenced, everything is measurable and every date lines up spatially.
3. Compare and quantify
Overlay against design to catch deviations (as-built vs design), and difference against the last capture to see what moved. Pull quantities — earthwork volumes, areas — that feed billing and reconciliation.
4. Share the evidence
Publish to a portal where owners, PMCs and lenders can see progress without a site visit, and export RERA-ready, evidence-linked packs. In 2026, AI will do the progress read automatically; until then it's fast, human-verified comparison.
Key takeaways
- Fixed cadence makes change detection meaningful
- A geo-referenced twin makes every capture measurable
- As-built vs design catches deviations early
- Evidence-linked packs make reporting defensible and RERA-ready
