Ground Data for Growth Bill: geotechnical data sharing explained for project teams
Reviewed by Joe Ashwell

First reported on New Civil Engineer
30 Second Briefing
Ground Data for Growth Bill proposes mandatory sharing and standardisation of subsurface investigation data, turning borehole logs, CPT results and geophysical surveys from individual project assets into a national digital resource. By reducing duplicated ground investigations and improving access to historic GI records, the bill aims to cut early-stage geotechnical uncertainty, programme risk and contingency allowances on major schemes such as HS2-scale corridors and urban tunnelling. For practitioners, this signals stronger emphasis on interoperable formats, metadata quality and long-term stewardship of ground models.
Technical Brief
- Designers are expected to integrate shared GI into federated BIM models, updating 3D ground models across project lifecycles.
Our Take
Given New Civil Engineer’s recent collaboration with Heathrow Airport on the 2026 Early Careers Innovation Challenge, the Bill’s emphasis on structured ground data could quickly filter into airport and major infrastructure concept work, where early-stage geotechnical assumptions often drive whole-life carbon and cost outcomes.
