LKAB, a large mining company in Sweden, is investing 290 million Euros in a new pelletizing plant in Malmberget, Sweden (MK3). The complexity of the project, the number of actors involved and the desire to involve end users such as industrial workers responsible for the future plant operations in the design makes VR an excellent enriched source of communication in the design review process. This paper describes a practical approach to facilitate decision-making, coordination and to communicate client requirements in the design review process using a number of collaborative VR (Virtual Reality) prototypes of the plant including the construction and installations. The model based working methods that are used in the case study is discussed in the context of lean construction. The case study shows that the use of VR has increased the value for the client and the reliability in the design process. VR mock-ups have also minimized the waste in the production phase by eliminating collisions between the different designs. Even though the Partnering concept facilitates the cooperation between the different stakeholders the main cause for the intense information flow and willingness to share the information has been the time pressure forcing the different design teams to act concurrently.
