Road-builders in the UK are using an unmanned flying drone as a surveying tool to capture detailed images of the construction path.
The 350-sq-mm remote-controlled device is like a helicopter with four rotors, and is fitted with a video camera.
The trial is thought to be the first use of a drone in the road-building sector and was initiated to test the system’s capabilities and to help one of the team’s surveyors pass the test needed to receive a licence to operate the vehicle.
The project is in Northern Ireland, where a joint venture (JV) of contractors led by UK-based Costain is widening a 14.5km stretch of road between Belfast and Larne.
