The Channel Tunnel Project Construction Essay

The line Tunnel Project Construction lay aboutTwo centuries ago, in 1802, a French mining engineer c eached Albert Mathieu was the original one to propose a delve under the English alley to link the UK and France. Since that time several proposals select been put forward up to now none of them could be realized due reasons such as lack of applied science or the critical relationship between these two countries.In July 1985 a proposal submitted by the Channel Tunnel company/France-Manche (CTG/F-M) swot up those put forward by their four briny competitors and was accepted. This proposal was amongst others to a greater extent(prenominal) favoured by the British and French g everywherenment due to the privately funded nature, financial robustness and technological simplicity.Scope of the ProjectThe channel turn over was purge was completed over 7 years time, involving 15,000 tempters at the peak of construction. The tunnelling commenced in 1988 and began to operate in 19 94. Eleven tunnel boring machines were used on both boldnesss of the channel to cut with the chalk marl and to construct 3 tunnels, 2 for rails and 1 for maintenance. The shuttle terminals are at Folkestone and Coquelles go up Calais and the main aim for constructing such a massive tunnel of 32 (50km)miles length, of which 23.6 (30km )miles are underwater, was to allow people to travel between those countries in an strange travel time of scarce 35 minutes.Main ParticipantsThe main participants were Channel Tunnel Group/France-Manche (CTG/F-M), which formed a new entity called Eurotunnel (ET), a bi-national company. ET was owned by money boxs and 10 other companies and is the owner and operator of the draw for 65 years, until 2052. and node of the asserter Transmanche Link (TML). Design, construction and commissioning fell in the responsibility area of TML and commissioning of the come out. An interesting align none is that both groups consisted of employees from France and the UK.This project is administer by the Intergovernmental Commission (IGC), on behalf of both governments to ensure the Eurotunnels compliance with the Concession. This physical structure was in charge of the brush uping form, procedures, specifications and in particular issues related to environment, operation and synthetic rubber of the tunnel.The Matre dOeuvre, an independent Consulting engineer, has been appointed technical auditor and was reporting to ET, the IGC and the Banks.engineering UsedEleven tunnel boring machines (TBM) have been used in total on both, the French and the British sides, to work their way through the chalk marl stratum, which is between the gray chalk and glauconitic layer. ( See Figure XXX).On the English terminals 6 TBMs were operating while on the French side five TBMs were used. Due to the high pressure nature of the water which were familiarise in the folded and faulted chalk on the French side, three special TBMs, videlicet Earth Pressur e Balance machines (EPBM), had to be used. On the English side, simpler alone faster open face TBMs head started digging from the Shakespeare Cliff.On average the TBMs worked 873 m per month. In the best month it cut back a world picture of 1,719m per month which yet has to be beaten.Project Life Cycle1) insertion April 1985 Promoters were formally invited by the French and UK government to submit scheme proposals for a fixed link between those countries-January 1986 Mandate awarded to the Channel Tunnel Group/France-Manche-Feb 1986 Treaty of Canterbury is signed allowing the project to go aheadSetup of IGC to grapple the project-April 1987 French Parliament allows the project2) Planning Design and financial backing Jan 1987 Design phase was relatively curtly as it was based on the 1975 project and the proposal which was submitted in 1985.

Separate project managers were appointed to manage the British side and French side they were Atkins and Partners (UK) and Setec (France) respectively. During the initiation phase the project managers designingned the project, agreeing on milestones and determining the tasks that would need sub-contracting. The project sponsors Eurotunnel justified the funding necessary and set up the success criteria.In the equity phase the project manager did not have a very big role.The optimistic plan to open the tunnel by May 1993 meant that the design phase was short with insufficient accuracy and detail. This had many repercussions and was the main contributor to the delays felt subsequently on in the project. In this stage the project manger was managing the over all drive of the project and ensuring the design met the concessions specifications. Eurotunnel set the time, cost, and quality specifications and set all minimum constraints. All major changes made to the design had to be approved by the sponsor.In the Development phase the project manager had to make a variety of managerial decisions to maintain and bring the project back on the required time schedule. The project manger was besides in charge of ensuring there was sufficient linking of tasks. The two teams met monthly to suss out progress and adapt schedules. Eurotunnel monitored the project progress from an objective point of view. Eurotunnel too reviewed and had final say on all major changes made to the design in this phase.In the Delivery phase the project manger and the sponsors review the project and decide whether the deliverables had been met. The contractors TML and the project managers handed over full responsibility of the channel tunnel to Euro-Tunnel who would have to fulfil the Concessions agreement for the rest of the date in which they would run the Tunnel. A statement of the ORIGINAL PROJECT OBJECTIVES duration The channel tunnel took 7 years to build. The first train carrying passengers and their cars journeyed to France on the 22nd December 1994. The initial plan has foreseen the tunnel to be pay off on the 15th May 1993 therefore the work has been completed more than one and a half after schedule. COSTThe Channel tunnel is the largest privately funded project in history. It was clear from the beginning that the two governments would not get involved in the funding of the project as this was the only basis on which Margaret Thatcher, British Prime Minister, would accept the project.Funds have been raised through equity raising in capital markets and loan agreements. In total more than 200 banks, including the founder shareholder banks Natwest and Midlands in the UK and the French banks Credit Lyonnais, Banque Nationale de Paris, Banque Indosuez raised a total capital of 4bn in various equity issues.The actual completion costs were at an 80% cost overrun in 1994 compared to the cost esti mate of 2600 compared by the contractor group TML in 1985. Underestimation of rolling stocks, changes in the fixed equipment work and terminals as well as the initially poor tunnelling process all contributed to the cost overrun. QUALITYAs mentioned above an organizations such as Intergovernmental Commission(IGC) and Matre dOeuvre (MdO) was a form of engineering supervision employed by the Eurotunnel. The main task of this body was to monitor all activities on the project and put out quarterly reports to keep government and banks updated whether the project was executed in consistency with the requirements of the Concession and the quality assurance standards established by TML.To achieve the required quality of standards a classification system has been used on the worry plane to make the whole process more flexible by assessing and prioritizing the tasks. Although quality requirements were of equal importance for every single task, the management entitle was categorized in 3 d ifferent levels according to complexity, maturity of the technology and overall impact of the task.
