Nuar underground asset register: strike-free excavation insights for civils teams

First reported on New Civil Engineer
30 Second Briefing
The National Underground Asset Register (Nuar), a government-backed digital map of buried pipes and cables, is expanding to target contractors with near real-time access to multi-utility asset data before excavation. The platform aggregates location information from water, gas, electricity and telecoms operators into a single online interface, replacing multiple separate searches and paper plans. For ground engineers and civils contractors, Nuar aims to cut service strikes and unplanned outages on streetworks and major schemes by providing faster, more accurate asset location snapshots at the planning and permit stages.
Technical Brief
- Safety case is framed around reducing cable and main strikes that currently cause injuries and traffic disruption.
Our Take
Within our 165 Infrastructure stories, relatively few focus on digital registries like the National Underground Asset Register, so this pushes the safety tag coverage beyond traditional themes such as site incidents and PPE into data-led risk reduction for contractors.
For contractors and utilities, a more comprehensive Nuar effectively shifts some duty-of-care expectations: once accurate underground data are widely available, regulators and clients are more likely to treat strike events as failures of planning rather than unavoidable hazards.
Because this is tagged to both Safety and Projects, Nuar’s evolution is likely to influence how early-stage project planning and CDM documentation are prepared, with asset location data becoming a standard pre-construction deliverable rather than an optional desktop study.
