145-151p. The Channel Tunnel Rail Link (CTRL) London Tunnels involved construction of 19km of underground railway. The capital value was around €780 million with an allowance of approximately 12% to cover risks including geotechnical uncertainties. Ealy problem cased the contigency fund to be spent before tunnelling commenced. Clearly the project risked major overspend. To overcome this risk a commercial alliance was established between the parties to share the remaining funds and work together to complete the project. This alliance changed the way the geotechnical engineering challenes were met. The team focessed on identifying the risks and selecting the best placed group within the combined team to manage each risk. No benefit could be derived from transferring risks unless it was to another part of the team with better skills to manage them. The immediate result of the Londong Tunnels experience has been the succesfuldelivey of the scheme well within the original programme and at the tender budget. The wider impact of this outturn may be in the planned adoption of similar models to deliver future major underground projects.
