The Geotechnical Baseline Report (GBR) is becoming a standard tool for delineating the baseline conditions for the purpose of risk allocation and management. However a GBR is not the only tool that can be used for this purpose. This paper explores these alternatives, with examples from completed projects, and attempts to identify whether there are common items that need to be incorporated into a contract, irrespective of the baseline form used, to aid the successful implementation of the chosen method.
