Glencar Construction is using the very latest in drone technology to bring benefits to site surveying and modelling processes including faster, more detailed and more accurate workflows.

Traditional drone surveying requires the setting out of multiple ground control points (GCPs) which can take hours to place, especially over a large site. Our survey drone features a real-time kinematic (RTK) unit on the drone which allows its photos to be geotagged to survey-grade accuracy, calibrated to as little as a single GCP.

As well as saving time, the RTK drone also creates much more accurate data than was previously possible. Even without GCPs, the achievable horizontal accuracy is up to 3cm and vertical accuracy up to 5 cm. An integrated flight planning app in the remote control includes all relevant surveying parameters to make the flight planning easy and efficient.

Captured data can easily be integrated into third-party photogrammetry software, delivering industry acceptable point clouds and 3D-models. These can be overlaid with design plans including those for services, thus helping to detect design clashes at an early stage and also providing a visual record of progress as the project progresses.

Processed data can also be used for digital terrain and surface modelling, mass and volume calculations, and building information modelling (BIM). Both 2D and 3D data is used in project progress meetings, driving regular coordination and project reviews.

“At Glencar, we have made significant investment in the very latest survey drone technology which is bringing multiple benefits to our engineering processes” commented Glencar Managing Engineer Andy Green. “It’s just one of the ways in which we strive to offer the very best service to our customers and very much reflects our ongoing commitment to continuous operational improvement.”
