Keeping the Hallandsås Tunnel Project on Track The construction of a railway tunnel through the Hallandsås ridge in southern Sweden has a long history, but the end is in sight with the start of traffic services scheduled for late 2015. To help meet the demanding project schedule and the challenges of performing tunnel excavation and detailed engineering design in parallel, Trafikverket, the Swedish Transport Administration, chose to advance its use of Building Information Modeling (BIM) practices with the help of Sweco Infrastructure AB. Sweco was given the responsibility for all BIM related strategy and coordination of the Hallandsås project including helping the project team implement effective BIM processes to optimize production, develop integrated 3D models through a collaborative design process, and use that information throughout the project lifecycle. The successful BIM implementation on this project, using Bentley(reg) ProjectWise(reg), MicroStation(reg), InRoads(reg), Bentley Rail Track, and Bentley Navigator, has resulted in innovative methods, reusable resources, a reduction in costs, and productivity improvements that help keep the project on schedule.
