Drone Surveys and Progress Monitoring for Construction
On site, decisions come down to quantities and programme. We document every stage with measurable data — from pre-construction existing conditions, through each valuation period, to post-construction checks.
What we do
- Pre-construction existing conditions and spot height surveys
- Earthworks and cut-and-fill volumes
- Periodic progress monitoring
- As-built surveys and design comparison
- 3D site models and BIM base models
- Reports for investors and the client’s engineer
Relevant services
Geomatics and engineering surveying
Topographic surveys, setting out, spot height plans, existing conditions surveys, cut-and-fill and volumes, as-built, road, corridor, utility and mine surveys — carried out under a licensed survey engineer.
Monitoring and change detection
Construction and mine progress monitoring, cut-and-fill change, development, forest, coastline, erosion and landslide monitoring; time-series orthomosaics, 4D GIS and scheduled flights.
3D modelling and digital twins
3D models of terrain, buildings, construction sites and facilities: point clouds, textured meshes, digital twins, BIM integration and web-based 3D viewing.
Typical deliverables
Topographic survey
A layered, scaled digital survey to Turkish large-scale mapping standards, with spot heights, contours, buildings and site features.
DWG, DXF, NCZEarthworks & volumes
Cut and fill volumes from the difference between existing ground and the design surface, with cross-sections, schedules and a checked and approved report.
PDF report, DWG sections, XLSXOrthomosaic
A georeferenced, distortion-corrected aerial image mosaic you can measure directly from.
GeoTIFF, ECW, JPEG 20003D terrain model
A 3D model of the ground and everything on it — surface model (DSM), bare-earth model (DTM), classified point cloud and textured mesh.
GeoTIFF (DSM/DTM), LAS/LAZ, OBJ, 3D TilesFAQs
Can drone surveys support interim valuations?
Yes — a report stating the method, survey date and accuracy figures can be used to agree quantities between the parties.
Can you fly while the site is operating?
Yes. Flights are planned around site safety rules and working conditions.
Other industries
Mining
In mining, production, inventory and safety all come down to the ground. By surveying pits, benches and stockpiles regularly, we reconcile production by volume and keep track of slope geometry.
Energy (solar, wind, power lines)
In energy assets, a small fault can mean a big loss in output. We support the whole asset life cycle with spatial data — from site selection to post-commissioning thermal inspection.
Agriculture
No field yields evenly. We map crop health with multispectral imagery, flag problem areas early, and help you put inputs where they’re actually needed.
Infrastructure and transport
Long linear assets take days to survey on foot. We map road, canal and utility corridors in a single pass and inspect hard-to-reach structures such as bridges and viaducts up close.
Urban and smart city
Running a city needs current, joined-up data. With up-to-date orthomosaics and a 3D city model, we build your building inventory and turn it into an urban GIS and digital twin platform.
Environment and forestry
Change in natural landscapes is slow but lasting. We monitor forest cover, erosion, water resources and land use with measurable data, giving environmental decisions a solid evidence base.
Disaster response and damage assessment
In the first hours after a disaster, an accurate, up-to-date map is critical. We map the affected area quickly, identify damage through before/after comparison, and provide a base for reconstruction.
