Drone operator embraces new technology to provide accurate survey data

Rowley Cory-Wright, director of commercial drone operators HexCam, explains the benefits of Real-Time Kinematic survey drones to capture data on cable corridor projects.
 
 
Linear construction projects with fast-moving work fronts can present challenges when it comes to obtaining accurate and up-to-date survey data. Obtaining height data every 10 metres using a GNSS rover can be time-consuming and may require multiple teams of surveyors to cover the full length of a site.
So, what if there was a solution that virtually eliminated boots on the ground and gave up to date, verified accuracy height data every 10 centimetres in only a fraction of the time?
The solution exists already and is being used on the East Anglia ONE cable corridor project. HexCam, one of the longest-established commercial drone operators in the UK, was one of the first to embrace a new generation of small Real-Time Kinematic (RTK) survey drones. The DJI ‘P4RTK’ aircraft allows a single team to collect reliable height data at 10cm intervals from a 50-metre-wide construction corridor at a rate of roughly 12 kilometres per day.
Cloud-based platforms allow easy collaboration within project teams to visualise and analyse the high-density survey data, opening up a whole new set of tools. Features such as timeline sliders and online comparison with design surfaces and cross-sections can help project teams objectively assess their progress towards final required grades and to plan and prioritise work.

This short video shows how you can make your project safer by minimising the time spent on site and by reducing the number of people and vehicles needed on the ground. Data is collected in an unobtrusive way, without the need to walk or drive across ecologically sensitive or reinstated areas.
