The Geospatial Commission publishes a project update on the National Underground Asset Register (NUAR) and invites participation from all asset owners in Northern Ireland and England. This publication marks the first anniversary of the build phase and provides a summary of progress over the past year, as well as the economic case and a timeline for the next two years. In line with the government’s growth priorities, NUAR will use modern technologies and ways of working to revolutionise the way buried infrastructure is installed, maintained, operated and repaired across England, Wales and Northern Ireland. The NUAR platform has developed well over the first 12 months of the build phase, and a large number of asset owners from across all sectors have already provided their data and signed agreements to allow it to be shared with others. In the next 12 months the Geospatial Commission will continue to seek user feedback, develop the service and engage with stakeholders on the future operational model of NUAR.
