Ordnance Survey has awarded its £6m national underground asset register (NUAR) data transformation and ingestion service contract to 1Spatial Group.
Under this new deal, 1Spatial Group will be responsible for the data transformation and ingestion (DT&I) services, which form part of the NUAR data lifecycle. It will be required to transition all asset owners (AOs) by 1 April 2026 and to develop a plan, in consultation with Ordnance Survey, for transitioning the remaining AOs before their next scheduled refresh date.
The NUAR Programme delivers underground asset data to thousands of utility users through the Safe-Dig User Interface, helping to improve the efficiency and safety of underground works by providing secure access to privately and publicly owned location data.
The contract for the data management company is expected to run for a total of just over five years from 8 December 2025 until 31 March 2028, with a possible extension until 32 March 2031.
1Spatial was one of six companies to submit a tender for this contract. Bids were also submitted by AtkinsRéalis, BlueRose Technologies, Datalynx, VAAMG Consulting and Ve3 Global.
