RELIABILITY OF ESTIMATING ROCK EXCAVATION COST IN TUNNELING SPECIFICATIONS

Tunnel construction requires large investments, and all decisions influencing the cost of tunnel construction and maintenance should be based on reliable estimates. Since 30% to 50% of the total tunnel costs is accounted for by the cost of rock excavation, the reliability of estimating the quality and quantity of different rock classes in a specific project is an important problem to solve. This paper provides an answer to this and some other problems, focusing on reliability of rock classes. A New Austrian Tunneling method (NATM) is described.
