Dani will present on the use of Geotechnical Data Reports (GDRs) and Geotechnical Baseline Reports (GBRs) in underground projects, highlighting the key differences between the two documents and the information each should contain. The presentation will cover the evolution of the GBR and the underlying philosophy behind its development. Dani will also emphasize the importance of a well‑written GBR with clear, measurable baselines, including examples of both well and poorly written baselines.
