ABSTRACT
To keep up with Stockholm’s rapid growth, the Slussen area is being revitalized with a new bus terminal built in bedrock. Buses will circulate inside the underground terminal hall around a central waiting area, and exit at ground level on the quay-side. This requires the excavation of more than 273 000 cubic meters of blasted rock to create three large, parallel caverns. Each cavern will be up to 28 meters in span width and 200 meters long. Nearby urban infrastructure and existing rock caverns have provided major challenges to the design of the terminal. BIM comes in handy when carrying out a production-friendly design that takes into consideration the surrounding complexities and limitations. BIM and 3D models have not only became a better alternative to traditional drawings, but are also essential tools for coordinating between different technical disciplines and highlighting risk management throughout the design phase.
