BIM-Based Design of Underground Works for the Réseau Express Métropolitain (REM) Project in Canada
Building Information Modeling (BIM) is an emerging tool in the tunneling industry. The need for development of an efficient system that improves interdisciplinary coordination and minimizes production time and human errors is essential in a fast-paced project. The purpose of this paper is to present an overview of BIM application in tunneling and illustrate the range of applicability in all phases of underground works. Examples are drawn from an advanced BIM system that was developed for the underground segment of the Réseau Express Métropolitain (REM) project in Montreal, Canada. Advanced analysis methodologies are applied to improve modeling accuracy, detect clashes and automate drawing production. Lessons learned from this project provide useful information for the implementation of BIM in future tunneling projects.
