As lead authors of Geotechnical Baseline Reports: A Guide to Good Practice (CIRIA C807), we are recognised as the industry’s go-to experts for the preparation and review of GBRs.
Our authority in this area is built on extensive experience across major infrastructure projects, including London’s Elizabeth Line (formerly Crossrail). We provide comprehensive guidance to help clients manage subsurface uncertainty and establish fair, transparent contract terms between owners, consultants, and contractors.
A well-prepared GBR holds contractual status and plays a critical role in:
- Allocating geotechnical risk equitably
- Reducing disputes and litigation
- Supporting realistic tendering
- Enhancing project planning and risk management
By setting clear contractual expectations regarding ground conditions , we help ensure smoother project delivery and stronger collaboration between stakeholders.
