Progress tracking, earthwork volumes, and as-built verification for contractors, developers, and project managers across Costa Rica's busiest construction market — accurate to ±2cm and delivered in 72 hours.
The Greater Metropolitan Area — the GAM that stretches across San José, Alajuela, Heredia, and Cartago — is where most of Costa Rica's construction happens. Free-zone industrial parks ring the airport corridor in Alajuela, vertical residential towers keep rising in Escazú, Santa Ana, and Curridabat, logistics warehouses fill the flats toward Heredia, and road and infrastructure works thread through it all. It is a dense, fast-moving, high-value market — and that pace is exactly what makes keeping accurate track of a construction site so hard.
On an active build, the ground changes every week. Earth is cut and filled, foundations go in, materials arrive and disappear, and the gap between what was designed, what was billed, and what was actually built can widen quietly until it becomes an expensive surprise. Traditional ground surveying captures a handful of points slowly and can't keep up with a live site; site photos from the ground tell you almost nothing about volumes or coverage. A drone survey closes that gap. A single flight turns the entire site into precise, dated, measurable data that the whole project team — contractor, owner, engineer, and quantity surveyor — can work from. To see what monitoring your specific site would cost, our instant quote calculator gives you a price in seconds.
Construction monitoring is repeat-business surveying: the same site flown on a schedule so the data tells a story over time. Each flight is captured with RTK GPS ground control so every dataset locks to the same real-world coordinates, which is what makes flight-to-flight comparison trustworthy. From those flights we produce the measurements and records that drive day-to-day decisions on a GAM project, from the first cut to handover. Before you commit, you can scope a single survey or a full monitoring program with our online quote calculator.
Dated, geo-referenced orthophotos and 3D models of every milestone — a true visual log of how the site advanced month to month. Ideal for owner reporting, lender draw documentation, and keeping remote stakeholders aligned without a site visit.
Survey-grade cut, fill, and net earthwork volumes calculated against the design surface or the previous flight — an independent quantity to reconcile against haul records and pay applications, replacing slow tape-and-grid estimates.
Fast, accurate volume measurement of aggregate, fill, and spoil stockpiles for inventory control and reconciliation — typically within 1–2% — without anyone climbing the pile.
Compare what was built against the design model to catch deviations early, document final conditions, and produce as-built records for close-out, facility management, and dispute resolution.
An open, cleared construction site is ideal for high-resolution photogrammetry, which produces a crisp orthophoto and dense 3D surface perfect for volumes and progress imagery. Where a site is partly vegetated, sloped, or bordered by trees and existing structures — common on Central Valley parcels carved out of coffee land or hillside lots — LiDAR earns its keep, returning multiple pulses to map the true ground surface beneath cover that a camera alone cannot see through. We match the sensor to the site, and on many monitoring programs use both, so your terrain model and your volumes are based on real ground rather than the top of the brush.

Request a Quote WhatsApp UsA general contractor delivering a warehouse-and-logistics facility on the flats near Juan Santamaría Airport came to us with a problem familiar to anyone running a large GAM site: the earthwork phase was moving quickly, the owner wanted monthly progress documentation for its lenders, and the contractor and the client could not agree on how much fill had actually been placed. Ground survey checks were slow and sampled only a few points across a site measured in hectares.
We set up a recurring drone monitoring program. On the first visit we established permanent RTK ground control and captured a baseline surface; from then on we flew the site once a month — and weekly during the most active earthwork weeks — capturing the same footprint each time. Each flight was processed within 72 hours into an orthophoto, a 3D surface model, and a volume report comparing the new surface to both the design and the previous flight.
This is the recurring value of monitoring from the air on a busy site: the data is objective, it is repeatable, and it serves everyone at the table at once. For developers earlier in the cycle — still verifying a parcel before breaking ground — the same technology supports land due diligence and subdivision planning across the Central Valley, and you can price either approach with our quote calculator.
All commercial drone operations in Costa Rica are regulated by the Dirección General de Aviación Civil (DGAC). On a construction project this is not a formality: data gathered by an unlicensed operator can be challenged in a dispute, and an incident on or near your site creates liability for the project. Our operations comply with current DGAC requirements, which apply consistently across every region we serve:
The Central Valley raises one issue more than any other region: airspace. Much of the GAM sits inside or beside controlled zones, including the airspace around Juan Santamaría International (SJO) in Alajuela and Tobías Bolaños (SYQ) in Pavas, as well as helipads serving hospitals and towers. We plan every flight around these constraints and secure the necessary authorisations before flying in controlled airspace — so your site documentation is gathered legally, safely, and without interfering with aviation around it.
Our survey team mobilises throughout the Greater Metropolitan Area with full equipment — LiDAR and photogrammetry drones, RTK GPS base station, batteries, and field laptops — scheduling flights around the dry morning windows that give the cleanest, most consistent imagery for month-to-month comparison.

Every Central Valley construction survey includes a full set of processed outputs ready for your engineer, quantity surveyor, or project manager:
Deliverables are compatible with AutoCAD, Civil 3D, ArcGIS, QGIS, and all major engineering and project-management platforms. We also provide KMZ overlays for Google Earth on request. For a full breakdown of what surveys cost, see our 2026 Costa Rica drone survey cost guide.

We fly your site on a recurring schedule — typically monthly, but as often as weekly for fast-moving jobs — capturing the same area each time with RTK GPS control for ±2cm accuracy. Each flight produces an orthophoto, a 3D model, and a terrain surface. By comparing flights we measure how much earth has moved, how much material is stockpiled, and whether built work matches the design, then deliver the data within 72 hours so the project team can act on it before the next pour or payment.
Yes. Volume measurement is one of the strongest uses of drone surveying. By capturing a dense 3D surface of the site and comparing it against the design surface or a previous flight, we calculate cut, fill, and net earthwork volumes — as well as stockpile quantities — to survey-grade accuracy. This replaces slow, error-prone tape-and-grid estimates and gives both contractor and client an independent number to reconcile against haul records and pay applications.
Absolutely. A dated, geo-referenced aerial record of every milestone gives owners and project managers an objective progress log, supports pay-application review, and documents what was actually built versus what was designed. As-built orthophotos and point clouds are invaluable for resolving disputes, closing out the project, and feeding facility records for the finished building or subdivision.
Much of the Central Valley sits inside or near controlled airspace, including the zones around Juan Santamaría (SJO) in Alajuela and Tobías Bolaños (SYQ) in Pavas. We operate in compliance with DGAC requirements and coordinate the necessary authorisations before flying in controlled airspace, so your site documentation is gathered legally and without disrupting airport operations.
A single survey starts at $1,000 USD for sites up to 5 hectares, including the flight, RTK GPS control, full data processing, and all deliverables. Larger sites are quoted at $80 per hectare, and recurring monitoring programs are priced per visit at a reduced rate once control is established.

From a single warehouse pad in Alajuela to a multi-tower development in Escazú, we typically confirm availability and quote within 24 hours.
