Monthly drone surveys that measure earthwork and stockpiles for contractor bills
TL;DR Moundcount flies a drone over road, industrial and township sites once a month and reports how much earth was cut, filled and stockpiled since the last flight. Main contractors pay to check what subcontractors bill them and to back their own claims to clients. The pitch is fewer billing disputes, not prettier progress reports.
Earthwork is paid by volume, and volume is always argued over. A subcontractor bills for cubic metres moved, the main contractor's surveyor checks a sample with a total station or tape over several days on a big site, and the two settle somewhere in the middle. Stockpiles of aggregate and sand get the same treatment at month end.
No public figure exists for how much Indian contractors lose to overbilling on earthwork. The method gap is clearer.
In a published quarry comparison, a drone survey measured a stockpile within 2.6% of its known volume in 35 minutes, while the tape method took 97 minutes for 1.3% error, and both sat inside the ±3% tolerance[1]. On a site with dozens of piles and kilometres of embankment, that time gap is the business.
What it does, in regulatory terms: aerial survey and measurement under India's Drone Rules 2021, flown by certified remote pilots in permitted airspace. Moundcount gives no structural or safety certification.
A pilot and a surveyor visit each site on a fixed day every month. They set ground control points, fly a mapping pattern and process the images into a surface model. The report compares this month's surface with last month's and with the design levels, giving cut and fill by chainage or zone and the volume of each stockpile. Disputed areas get a re-flight within a week.
The seed proposed autonomous flights checked against 4D BIM. We reframed it, because BIM adoption in India is about 10–18%[2] and road and earthwork packages rarely have a 4D model at all. What contractors do have is a bill of quantities and a monthly payment cycle, so Moundcount measures against those.
The main contractor's planning or billing team pays, per site per month. A typical service might run ₹40,000–1.5 lakh a month depending on area (our estimate, to test). Developers of industrial parks and townships are a second buyer, checking their own earthwork contractors. Quarries and cement plants with stock audits are a later, adjacent market.
The 2021 Drone Rules cut the paperwork sharply - most flights in green zones up to 400 feet need no prior permission, and the number of forms dropped[3]. Processing software and capable mapping drones are standard kit now. Indian drone analytics firms already sell into road projects[4], so buyers have seen what the output looks like.
There's no public figure for spending on drone earthwork surveys in India. One Bengaluru drone firm says its platform cuts road land-survey timelines from months to days and tracks stockpiles for mining clients[4], which shows paying demand in adjacent work.
The narrow test is simple. Will one contractor pay monthly for billing checks on one site?
Bengaluru drone-analytics firms sell a drone analytics platform for roads and mining[4]. Global AR survey tools let crews measure cut, fill and volumes on the ground with a tablet and GNSS receiver[5]. Plenty of local drone service firms fly one-off surveys.
The gap is a fixed monthly measurement tied to the billing cycle, using the same method every time so both parties trust the numbers.
| Difficulty | Moderate (49/100) |
| Starting capital | ₹80 L–1.5 Cr |
| Time to launch | 4–6 months |
Flying is the easy part. The hard parts are keeping survey accuracy steady month after month, getting both sides of a billing dispute to accept your number, and running pilots across scattered sites. Airspace near airports and defence areas also blocks or slows down some sites.
Yes, flying drones commercially needs approvals under the Drone Rules 2021, issued through the Ministry of Civil Aviation.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI settle a payment dispute. The volumes feed a bill, so a qualified surveyor checks ground control and signs every report, which is a measurement, not a certified survey.

Here's what can go south -
I think this is a practical services business for someone with land-survey or civil-billing experience. If you want pure software margins then look elsewhere. First prove that one contractor changes a real subcontractor payment based on your report and keeps paying for three months.
Plan for roughly ₹80 L–1.5 Cr, covering certified drones, survey kit, software, pilots and early contracts.
Yes. Under the Drone Rules 2021 you register each drone, use certified pilots and get permission before flying in yellow or red zones.
Yes, contractors everywhere bill on earthwork volumes. Each country has its own drone registration and pilot rules, so check those first.

Thinking about building Moundcount or something close to it? The make-or-break work is getting both contractor and subcontractor to accept the same volume figure. If you need a hand with that, you know where to find me. Talk to Yash →
