The experience from normal tunnel design should not have been applied mechanically; the outcome was that all the stakeholders had to face the technical, financial, even political risk. The Channel Tunnel was to be built under the English Channel comprising two parallel railway tunnels. Since the expected ROI of the project was calculated based on optimistic forecasts, it seems Eurotunnel may not be able recoup its due profits. Moreover, there was no fire-testing for the high strength concrete. The project team were able to understand the complexity and were able to use previous research on the soil, but in the end, the lack of continued focus on the scope resulted in the frustrations of trying to do too much. In conclusion, the Channel Tunnel project reflects one of the crowning achievements of modern-day engineering, and deserves its place as one of the Wonders of the World. As mentioned earlier, the rate of tunneling in the initial stages was slower than expected, and the labour costs on the British side were higher than expected Costs, Risks, and Financing.
This time however, they awarded the project to a private company to fund it. Return on Investment R. Moreover, there was no fire-testing for the high strength concrete. While there was some technology risk involved in the Channel Tunnel project, this was mitigated by detailed geological studies of the strata where the Tunnel was to be constructed. Eurotunnel decides to change safety regulations to allow trains to travel in the tunnel, including high speed trains that did not split. This was done on an interim report as well as the final draft, and many helpful suggestions were exchanged. The delay in financing led to a corresponding delay in purchases and procurements.
Among political hiccups from the British side, had been the change in government from Conservatives more capitalist to Labour more leftist. However, one of these TBMs did not function well, leading to a lot of delays in exchanging and switching equipment.
The Channel Tunnel (Chunnel) Project Case Study
Log In Sign Up. In fact, many of the main problems with the Channel Tunnel project could be said to stem from the need to break up the monolithic credit risk involved. Concrete linings, which comprised mm thick concrete, were used to help the prject withstand the intense pressure from above as well as to help waterproof the tunnel.
Research Methodology Peoject make the research reproducible, this section was organized to present the planning skeleton. As such, there were constant delays and false starts at this stage.
Case Studies in Project Management – The Chunnel Project – Knovel
The initial cost models were based on the assumption that the tunnels would be completed on time and cunnel generate revenue.
Kirkland, Technical Director of the Eurotunnel from through View Section, Table of Contents. Also, the oil crises due to the Yom Kippur war and the boycott of the Arab countries thee oil to the west had caused financial instability that almost led to the cancellation of the project. In this analysis, technical details were de-emphasized to understand the bigger picture of project management.
According to the Channel Tunnel Treaty, the tunnel would have to be funded completely through private investors without any help from the government.
However, there are lots of experience and lessons in this project that we could benefit from. Skip to main content.

More importantly, the lack of communication during the initial phases led to differences of opinion in the later stages. Following the choice of the Channel Tunnel proposal, the scope of the project was defined as a linkage to connect transportation networks of France and the UK. Initially, the project was in effect executed as two separate projects, one of the French side and one on the British side.
The initial contract and winning contractor were described in detail. The governments were slow in processing these approvals. Luckily, inthe Conservative party returned to power again.
The timeline was compiled from secondary data sources, along with the other proposals. The use of the better equipment resulted in a higher quality of work, providing an unexpected benefit.
In the end, clear definition of mutually agreeable working arrangements was instrumental, particularly in light of the bi-national scale of construction. A Project Management Perspective The redesign caused unexpected delays and high costs. In order to confirm ground condition, it was decided that the service tunnel would always be driven not less than 1km ahead of the trailing rail tunnels to act as a plot.
Among some issues that came from the need for increased communications was language- related. This had happened inaround which time the cost of the project almost doubled. Unfortunately, the team could not find any detailed breakdown of the figures estimated in the original cost-benefit analysis.
A Project Management Perspective The lack of a fixed scope from a strong dedicated design phase and constant IGC intervention led to significant scope creep.

The overall study was researched and loosely compiled with the following outline: Flyvberg for example mentions the possibility of using projects of similar scale and scope to apply reference-class forecasting. Since the Channel Tunnel contract was a Chunnl contract, the performance and maintenance of the Tunnel since completion have also been compiled. In this case, the importance of the early project phases is shown perfectly.
