The existing tidal defence infrastructure along the Hull frontage had been deteriorating. Mott MacDonald and BAM Nuttall needed a highly accurate digital replica of the site to aid with design and planning permission so they could assess the current flood risk and propose a solution. This digital twin would operate as a single source of truth about the spatial dimensions and features of the current coastal defences across 10km of complex waterfront.
By utilising UAVs, Sensat were able to capture, digitise and deliver an accurate 3D digital model of the site in just 2 days. Lendlease were able to completely circumnavigate the need for track access approval, land access approval, and traffic management; saving both time and money.
The visualisations created from the UAV survey included a high-density point cloud, DSM, orthomosaic, and 3D mesh. The data can be integrated with CAD and BIM to provide an incredibly detailed, versatile and collaborative digital environment in Sensat’s visualisation platform.
