Drone Construction Monitoring, Volumetrics and Progress Tracking
Construction teams fly repeatable drone surveys with UgCS, then store, compare, and share the results in DroneGIS to track progress, measure stockpile and excavation volumes (cut-and-fill), and document the site over time.
Repeatable missions: re-fly the identical path, altitude, and overlap every cycle.
Works with DJI, Autel, Freefly, ArduPilot, PX4 & NDAA compliant drones, including 100+ drone platforms.
For Utility Mapping, Bathymetry, and pre-construction applications.
5,000+ professionals trained, customers in 150+ countries.
Why Construction Monitoring Is Hard to Get Right
Site monitoring means repeating the same survey for months, not running one and moving on. The hard part is making each one line up with the last so the numbers you report can be trusted.
Surveys that don't line up
If every flight uses a slightly different path, altitude, or overlap, the datasets don't register against each other. Comparing them then measures the difference between two flights, not the change on the ground.
Inconsistent GSD on a site that changes daily
Excavation and fill change the surface between visits. Apps that fly a fixed height above the takeoff point produce uneven pixel size.
Incomplete stockpile and excavation geometry
Straight-down (nadir) patterns see the top of a stockpile or the rim of a cut, not the sides. Volumes built from top-down geometry alone undercount material.
Data scattered across SD cards and laptops
Progress and volume reports have to be compared across flights, dates, and teams. Without one place to hold and compare surveys, data sits on flash drives and individual machines and stakeholders never see it.
Reporting cadence versus field time
Weekly or monthly progress and volume reports take too long when each one means a ground crew walking the site. The monitoring loop has to be fast enough to keep up with the build.
How Drones Improve Construction Monitoring
Drone surveys turn site monitoring into a repeatable loop: fly the same mission, measure the change, report it, repeat.
Repeatable missions for valid comparison
Build the mission once in UgCS, save it, and re-fly the identical path, altitude, and overlap on every visit. Repeatable flight planning is what makes month-over-month comparison meaningful, the same approach researchers used to track individual plants across three years of surveys.
Uniform GSD across changing terrain
UgCS terrain following holds constant altitude above ground using your own high-resolution DEM, so pixel size stays consistent from flat pads to steep cut faces and stays consistent between surveys. Deliverables: orthomosaics and digital terrain models that compare cleanly over time.
Complete geometry for accurate volumes
Circlegrammetry and double-grid patterns capture the sides of stockpiles and excavation walls that nadir missions miss, giving the full geometry needed for stockpile management and cut-and-fill volume reporting, not just a top-down estimate.
One place to compare surveys and share results
Upload each survey to DroneGIS, SPH Engineering's cloud sharing data platform, to keep all site data in one place, compare surveys over time for change detection, and share progress with stakeholders through a browser.
Fast enough to report often
Preplan the mission, fly it autonomously with battery resume, and move from flight to numbers quickly. BHP delivers stockpile volume reports in under an hour. At that speed, frequent monitoring practical.
No crew on hazardous ground
Steep cut slopes, unstable stockpiles, and active work zones are surveyed without sending anyone in.
The Construction Monitoring Loop, Step by Step
Plan once, re-fly every cycle
Build the survey in UgCS on a desktop: import the site boundary (KML) and elevation model (GeoTIFF DEM), set altitude, overlap, and camera parameters, and save it as a template. Every monitoring visit re-flies the identical mission.
Fly with terrain awareness
UgCS terrain following holds constant AGL using your DEM. For sites that change daily or surveys requiring the highest level of precision, add SkyHub with a radar or laser altimeter for True Terrain Following that corrects altitude in real time from the actual surface below.
Process volumes and surfaces
Process the imagery using your preferred photogrammetry tool (Pix4D, Agisoft Metashape, or similar) into orthomosaics, point clouds, digital surface models, and volume and cut-and-fill figures.
Compare and report in DroneGIS
Upload the results to DroneGIS, compare each survey against earlier ones, and share progress and volume figures with management and clients through a browser. Every survey, date, and report stays together instead of scattered across drives.

Frequently Asked Questions
How do drones track construction progress over time?
You fly the same mission on a regular cadence and compare each survey against the last. UgCS saves the mission so the path, altitude, and overlap are identical every time, and DroneGIS stores the surveys so you can compare them over time and share progress with stakeholders.
How accurate are drone stockpile and excavation volume measurements?
With consistent AGL, sufficient overlap, and RTK corrections, drone photogrammetry delivers volumes within 1-2% of traditional ground survey methods. BHP relies on drone volumetrics for stockpile reporting at operating sites.
How often should I survey a site for monitoring?
It depends on how fast the site changes; daily and weekly cadences are both common on active earthworks. Because the workflow moves from flight to volume numbers in about an hour, frequent monitoring stays practical.
What does DroneGIS do, and is it processing software?
DroneGIS is a cloud spatial data platform for storing surveys, comparing them over time, and sharing results with customers or other team members through a web browser, not photogrammetry processing software. You process imagery into orthomosaics, point clouds, and volume figures in tools like Pix4D or Agisoft Metashape, then upload the results to DroneGIS to where you compare them against earlier surveys and share figures with your team.
Can I monitor a site without internet connectivity?
Planning and flying work fully offline in UgCS: cache maps and elevation before going to site and fly with no connection. DroneGIS is cloud-based, so uploading and sharing surveys needs a connection once you are back online.
What drones and sensors work with UgCS?
UgCS supports DJI Enterprise series drones (Matrice, Mavic Enterprise), Autel, Freefly, ArduPilot, and PX4, 100+ platforms in total. Discover the full list of UgCS-supported drones. SkyHub integrates real-time terrain following functionality and other payloads via serial or Ethernet.
What is the difference between terrain following and True Terrain Following?
Terrain following in UgCS uses your imported DEM to adjust altitude along the planned route. True Terrain Following (SkyHub plus a radar or laser altimeter) corrects altitude in real time from the actual surface below, which matters on sites that change daily from excavation and fill.
