LiDAR and GNSS
CADS’ drones use a LiDAR (Light Detection and Ranging) scanner to measure how long it takes for a laser pulse to bounce back off surfaces to calculate distances.
Coupled with GNSS (the Global Navigation Satellite System), the information is brought together in a point cloud which provides highly detailed data from which 2D plans and 3D models can be produced.
“Surveying has progressed enormously since we began with a tape measure and hand drawn plans! The biggest change in the built environment is the pace at which things need to happen. Coupled with all the support we deliver, drone surveys get our clients the data they need fast.”
Topographical surveys, sustainability certification and construction quality assurance
CADS reports drone scanning is being increasingly used for topographical surveys (of a site’s features and contours) to create land survey drawings and digital terrain models.
As CADS’ drone technology is able to capture high-resolution imagery, it is also used for applications including the inspection of inaccessible roofs or to provide ‘as-built’ data to ensure construction projects are being delivered to plan.
In addition, CADS is also using drone technology for infrared imaging to evaluate a building’s thermal properties and help them achieve BREEAM certification for sustainability.
Drone land surveys
In addition to traditional terrestrial topographic surveys, CADS is now offering Drone Land Surveys. These are fast and cost-effective solutions for mapping the natural and physical features, contours and elevations across vast sites.Drone land surveys
Critical data and imagery in a matter of minutes
Digital models foster seamless collaboration and risk mitigation in building construction
With new technology being increasingly exploited for constructing and maintaining buildings, 2D and 3D digital models provide an easy-to-use visual medium to help facilitate collaboration between all project participants.
As well as forming the foundation of the design, survey data helps architects assess risks and plan projects to avoid potential issues or delays.
“It wasn’t long ago that accessing every square metre of a site was time consuming and often hazardous. Now, the drone can gather critical data and imagery in a matter of minutes.”
Adding value with fast and accurate data
Maintaining a built environment
CADS’ survey team work with architects, project teams and building contractors across the UK and beyond, to deliver fast and accurate data which adds value to the whole construction process.
“Due to demand, drone surveys are becoming the norm for land surveys and we’re delighted to play a role in helping the UK create and maintain a built environment ready for the challenges ahead.”
