Abstract
In this study, a work information classification system for the TBM tunnel construction was proposed along with a conceptual model of an automated cost estimation system, with the goal of relieving the cumbersome operation of existing systems. The conceptual modeling of the automated cost estimation system involves systematizing the construction cost estimation process, by organizing a work information classification system in the form of a relational data base which reflects the processes that comprise the construction work. This proposed automation system is expected to be effectively applied to TBM tunnel construction sites as a scientific cost estimation system.
