Description The book relates experience of TBM drives in difficult geology, making use of case studies from Turkey to demonstrate the influence of the local geotechnical conditions on the selection of a tunnel boring machine and the selection of tools.
By 1909, the cost of construction had bankrupted the Illinois Tunnel Company. By this time, it was estimated that $30,000,000 had been spent on building and operating the tunnel.
The first successful tunnelling shield was developed by Sir Marc Isambard Brunel to excavate the Thames Tunnel in 1825. However, this was only the invention of the shield concept and did not involve the construction of a complete tunnel boring machine, the digging still having to be accomplished by the then standard excavation methods.
The purpose of this research was to determine if communication might be a foundation area of project management, with the other cornerstone areas as derived from previous research and the rest of the areas, and the means of achieving the trade off, as pillars or support.
