Crossrail’s Experience of Geotechnical Baseline Reports

Summary

This document sets out to record Crossrail’s experience of the use of Geotechnical Baseline Reports (GBRs) in its construction contracts. In reading this report it is important to remember that in all of the major Crossrail Civil Engineering contracts Contractor design activities were limited to temporary works only. There were no Contractor design and build aspects to the permanent works. This greatly simplifies the production of Geotechnical Baseline Reports.
