About Session
Norway has one of the most digitized construction industries in the world, with extensive BIM requirements for buildings, roads, and rail, and an impressive ~50% BIM project penetration rate. The national asset owners (Statsbygg, Bane NOR, Statens Vegvesen, etc.) have set ambitious targets and project requirements for BIM, driving significant strides in the adoption of new technology, standardization, and model-based projects over the last 10 years. As a result, national asset owners have been able to reduce change orders by ~60% and design costs by up to ~20%.
Recently, COWI and Novorender have applied this model-based approach to Norway’s largest infrastructure project, Fornebubanen: a 7.7 km long railroad project in Oslo with a budget of over 3 billion EUR, including the construction of six new metro stations, more than 10,000 homes, and commercial properties to support over 20,000 new jobs. The associated BIM model of the project consists of ~1,200 different models from over 20 disciplines, ~10 million unique objects, each with 50-100 properties, and, in total, over 10 billion polygons – probably the world’s largest BIM model!
