In a fraction of the time it takes to conduct a ground-based survey, a drone can fly and capture imagery of a project site that can then be processed into highly-accurate point clouds compatible with Building Information Modelling (BIM) software.
These point clouds are a 3D visualisation made up of thousands or even millions of georeferenced points which produce an accurate representation of the site, where both horizontal and vertical objects can be mapped.
Since this method of surveying does not require direct contact with the object, drones can be employed for tasks with minimal or no disruption to live processes and with a reduced risk to the health and safety of individuals, which ensures a much better reconstruction of the 3D model.
Drone surveys can be used where access is difficult or restricted, i.e. busy sites, old industrial compounds, buildings or grounds where asbestos or other contaminants are present or where the stability of structures is questionable.
There are numerous benefits achieved through the use of drone-based surveys, these include:
Even compared to new measurement equipment, such as GPS Rover, the drone has many advantages, these include:
The drone industry has seen a boom over the past 5 years, with survey grade, off the shelf packages available for a moderate cost. It is expected that drones will eventually become common place in the surveying industry as they are now at Careys.
