Model-Based Concrete Design at the Fornebu Metro Line

Fornebu Metro Line is an ongoing metro line project in Oslo, Norway, connecting Fornebu with the existing Oslo City metro line through 8 km of tunnel and 200,000+ cubic meters of concrete split into six different metro stations and a service area. The majority of the concrete elements are cast in place. The elements vary from standard 200 mm inner walls reinforced in both directions on both sides to slabs and walls modeled in Revit that are 2.3 meters in thickness with several layers of reinforcement. Construction on the tunnels is ongoing. The stations are currently in the tender process with construction planned to begin in 2024/2025. As Norwegian governmental agencies want to stimulate innovation in the industries they interact with, Fornebu Metro Line has ambitions to produce project deliverables on a zero-drawing platform using Industry Foundation Classes (IFC) and DWGs™. The main building information modeling (BIM) viewers are Navisworks software and Solibri. BIM 360 software is being used for coordination and review.
