TUNNEL CONSTRUCTION IN DIFFICULT GROUND CONDITIONS

Tunnel construction has always been an extremely high-risk form of contracting because of the difficulty involved in getting information about the ground conditions that can be encountered during excavation. And, although every effort is made to overcome this problem through borings, geological research, site visits, and so on, owners, engineers, and contractors are only able to interpret a relatively small amount of data from isolated sections of the project. In addition, it is often economically or physically infeasible to obtain information and, of course, the total picture is never known until the project is complete. This problem affects the contract format as well as price.
