Increasing demand for digitally integrated design and execution in the building and construction industry places great demands on the establishment of data environments. Processes and organizational measures must be established that support project execution, where data loss is avoided, where the entire project lifecycle is considered, and where it can be monitored and analyzed directly from models. At the same time, customers and partners want to follow the project development to a greater extent on a transparent data platform in new forms of collaboration, such as alliance and integrated project delivery (IPD). Add to this the fact that automation is to a greater extent a crucial competitive parameter and an important factor in reaching project deadlines. This presentation describes how a project can be established organizationally and digitally to achieve a high degree of seamless collaboration across disciplines, companies, and software. It also describes some of the digital solutions that have been established, as well as some ambitions for where the project is going for the next seven years. The article is based on the Fornebubanen, which is a multidisciplinary project with 52 disciplines and a construction budget of just more than 1.6 billion Euros. The goal is to have the most information such as bills of quantities, commercial requirements, CO2 imprints, classification, and operation and maintenance information linked directly to the models. These models are combined into several coordination models for a holistic and multidisciplinary representation of the total digital project. Processes, quality assurance, ICE (simultaneous design or "integrated concurrent engineering"), design reviews, tender basis, and execution basis are all based on the project's digital 3D information models. These collaboration models are produced as geographic information system (GIS) models for overall understanding and as technical collaboration models for issue handling and technical assessments and communication. Gamification and a digital asset model will be presented to the stage it has been developed.
