Oslo Airport Expands its Terminal with openBIM® and Environmentally Sustainable Design

Project Overview About the project Local timber from Scandinavian forests was Aas-Jakobsen (Team_T) Oslo Airport in Norway was built in 1998 used for cladding of the new pier. It was hoped with the capacity to cater for around 17 enhanced levels of insulation would provide Location: million passengers annually. In 2009 work better energy performance and regulation. The Oslo, Norway began on a two-stage expansion project to client hoped to achieve a high BREEAM rating increase capacity while adding innovative and through sustainable methods. Objectives: environmentally sustainable designs to the To expand the airport terminal airport. Stage one would increase passenger Project teams were also instructed to work and reach high envrionemtal capacity to almost 23 million annually by 2013. collaboratively through common goals and BREEAM score. exchange methodologies.

Much of the success can be attributed to the mandate of IFC format for BIM deliverables, enabling a truly openBIM approach. Applications like Revit, , ArchiCAD, Vectorworks, MicroStation, NovaPoint and Rhinoceros Grasshopper delivered models in IFC format.
