Learn how Network Rail and WSP saved time and money on early stage infrastructure design in Cambridgeshire at a fraction of the cost

The project

To support early-stage design, Network Rail and WSP needed highly accurate survey data of a large complicated area composed of rail, road, greenfield and urban areas.

The solution

Utilising UAVs, Sensat seamlessly captured, processed and quality assured data in just 10 days. The visualisations created from the UAV survey included a high-density point cloud, DTM, orthomosaic, and 3D mesh. This was above and beyond the client’s initial objectives for the survey. The data can be integrated with CAD and BIM to provide an incredibly detailed, versatile and collaborative digital environment in Sensat’s visualisation platform. The platform also enabled the train mounted LiDAR data to be layered into digital twin which had proven accuracy of 1-3mm, perfect for detailed design.

WSP saw cost savings of up to 70% over using a more traditional survey method such as a total station or laser scanner.
