Drone Construction Progress Monitoring
Dated aerial evidence of what has actually been built, reported work front by work front. Owners, lenders and EPC teams verify progress on solar and wind sites, including their civil works, without relying only on site visits or self-reported percentages.

In short
Drone construction progress monitoring is recurring aerial capture of a site, compared across dates and against the plan, to confirm what has been built. Lesoko reports what is visible and measurable from above: activity stage, who and what is on site, volumes moved and installed geometry.
Compared with site reports: dated aerial capture is not self-reported, and every cycle uses the same work-front labels, so progress stays comparable. Hidden or below-grade work cannot be seen from the air and still needs field records.
Check claimed progress against dated imagery before a milestone is approved.
Keep a time-stamped record of every work front and plan next-day crews from current site data.
Hold an independent visual record across projects to support site reviews and certification.
Scope
Other asset types are scoped per project, with the measurement method agreed up front.
Selected output
Captured on the same cadence so changes are comparable.
The project’s story from first activity to latest capture.
One line per turbine, block or building, with stage and status.
For excavation pits and earthwork areas.
Solar table height, ground clearance, spacing and offset.
Idle workers and night-shift activity.
Format, cadence and tolerances are agreed in scope before capture.
SAMPLE OUTPUT: STATUS REGISTER
Reporting
Each work front is reported against the agreed baseline: the schedule, drawings or milestone plan from the owner or EPC. The gap between what is built and what should be built is reported per work front, so delays are visible early.
Example of the report layout only. Figures are placeholders; real reports use your baseline and dated captures.
| Work front | Planned | Observed | Deviation | Status |
|---|---|---|---|---|
| Foundation | 80% | 74% | -6 pts | Behind |
| Structure | 65% | 68% | +3 pts | On track |
| Module Installation | 40% | 32% | -8 pts | Behind |
We confirm the schedule, drawings or milestone plan the percentages are measured against before the first capture.
Stage and quantity come from dated imagery and measurements, not contractor-stated percentages.
Ahead, on track or behind, with the capture date that supports it.
The same work-front labels each cycle, so trends and slippage can be tracked across reports.
The wind register above shows 4 of 13 turbines installed; comparing that with a programme needs the turbine schedule, agreed in scope.
Project evidence
These are recorded findings from completed Lesoko inspection projects — the actual scale and defect data, not illustrative examples.
Solar Project · Madhya Pradesh
250 MW
Keeping visibility over a large solar build across day and night shifts.
Work progress, night-shift progress, idle workers, panel cleaning, missed portions, table height, clearance and offset.
Stakeholders had a consistent visual record to plan the next day's work.
Solar Plant · Raipur region · Weekly report, 11-17 Jan 2021
68 MW
Several civil and infrastructure activities moving at once.
SCADA room, three inverter rooms with water tanks, culvert levelling, periphery road cleaning and levelling.
Dated evidence for each work front, comparable across the week.
Wind Farm Installation · Turbine locations in one report
13
Turbines, substation and yards at different stages simultaneously.
Foundations through crane assembly, lifting and installation, plus substation, storage yard, office and shed.
A single register showed 4 turbines installed and 9 in progress.
How it works
Choose the areas of your site, your schedule, and what the reports should help you decide.
Airspace assessment, site permission and safety induction are coordinated with your team, including night flights if needed.
The same areas every time, so each date compares cleanly.
Every capture is compared with the last one and with your schedule.
Progress by area, plus anything missing or running behind, ready for reviews and approvals.
Accuracy & standards
The schedule, drawings or milestone plan that progress is measured against is confirmed in scope before the first capture.
Every image is dated and filed under a fixed work-front label, so each cycle can be compared with the last.
Each work front is checked against its previous capture and against the plan before a status is assigned.
Measurement method and on-track tolerance are written into scope, so any deviation can be traced to how it was measured.
