Developing an Information Modeling Framework for Tunnel Construction Projects

Abstract

A plethora of information combined with the participation of diverse disciplines during the tunneling life cycle results in fragmented information components. To address this problem, integrated information systems provide a unique environment to store project information. In this regard, consistent data structure facilitates successful information exchanges between project segments. This thesis presents an integrated Tunnel Information Modeling (TIM) system similar to the vastly studied Building Information Modeling (BIM) concept. The proposed TIM model offers a multi-dimensional modeling procedure to develop an integrated and interoperable tunnel information model. The extension capability of the current Industry Foundation Classes (IFC) standard is utilized to define new classes for tunneling construction projects. The aim is not to develop an extension domain for the IFC data model, but to propose a step-by-step framework to achieve such an extension for tunneling projects. The resulting framework can be used as the primary component for developing an object-oriented application interface.
