Abstract
The important issues related to the performance and cost estimation of hard rock Tunnel Boring Machines (TBM) are presented and discussed in this paper. General approaches for performance prediction of TBM, which is one of the most popular mechanical excavators are addressed. Two of the most successful performance prediction models, namely the Colorado School of Mines (CSM) and the Norwegian Institute of Technology (NTH) models and their most recent modifications, improvements, and some recent applications are presented. A comparison is made between the results of both models in two tunneling projects.
