Design and Construction of McGill Station in Downtown Montrea l
McGill Station is being constructed as part of the multi-billion-dollar Réseau Express Métropolitain (REM) design-build project in the Greater Montreal region. The station building is a steel framed structure built as a shallow cut-and-cover construction under an active street between two existing buildings. Located in a dense urban landscape posed unique challenges in the design and in the need to integrate essential mechanical, electrical, and tunnel ventilation systems within the limited space. This paper presents the design complexities encountered in the project and discusses its unique features. The paper highlights the benefits of using Building Information Modelling (BIM) throughout the design and construction phases to improve design efficiency and multidisciplinary coordination, resolve clashes, and reduce potential delays during construction.
