Geotechnical baseline reports (GBRs) provide a mechanism for developing equitable contracting arrangements between clients and contractor when dealing with the uncertainty in ground conditions encountered during the delivery of capital projects. 

The talk will outline the context and need for GBRs and why and how CIRIA has worked to develop this guidance. The presenters will outline the principal features of the guide, drawing upon their extensive UK and international experience.

Case studies to illustrate how and why GBRs are useful will be provided.
