Openness between design and construction teams helped learn more about building information modeling (BIM) and find good practices in the Crusell bridge project in Helsinki, Finland. Many changes were implemented in the structure of the bridge after competitive bidding, as was suggested by the contractor. During the final structural design phase, a shared model was being synchronized on a web server. The project parties sharing the building information model were the designer, project owner, general contractor and many subcontractors.
