BIMlink is an online Building Information File for storing and managing information about every stage of the development, design, construction and management of a building. All documents, drawings and models in the spatial structure of a building are continuously collected in BIMlink and transparently made accessible online in one place and in a structured way during all life stages of the building. All project partners get specific access to the most current data from the Online Building Information File that is relevant to them. This way, the building is efficiently built and managed as a co-production.
