GCG congratulates its Senior Partner John Davis for publishing a very important & useful article entitled “Geotechnical Baseline Reports (GBRs) – ground models you can just make up?” in the Quarterly Journal of Engineering Geology and Hydrogeology (QJEGH).
This paper is based on a presentation given at the 2019 Engineering Group of the Geological Society (EGGS) conference held in Cambridge.
GBRs are commercial documents used to allocate ownership of below ground construction risks to either Employers or Contractors.
The paper sets GBRs in the context of engineering geological ground models as set out in IAEG Commission 25 ‘Engineering geological models: an Introduction’.
One of the roles of a GBR is to characterise any potentially adverse encounters with the ground during construction that have not been characterised by ground investigations. Fulfilling this role largely relies on the use of conceptual ground models.
