A key to successful use of BIM is understanding who will use the BIM-model and understanding what kind of information the users will need to withdraw from the model. The Randselva bridge BIM-models are being used for multiple purposes along its way from design to operational state, as illustrated in the BIM workflow in the figure below. Users of the multiple stages will normally have different information requirements and use different software to extract the data.

Figure.1. Workflow of creating and using BIM model

On the Randselva bridge project, multi-disciplinary control and 3rd party control are mainly done by using SolibriTM in combination with BCF-files.

At the construction stage, the model is being used for the following four main purposes schematically shown in the figure below:

A. Earthworks and backfilling

B. Constructing scaffolding / Surveying

C. Producing and placement of third-party products

D. Installing reinforcement (and post-tensioning)

These four different purposes all need specialized software and work methods.
