Open Approach to BIM in use in Järvenpää
The new social and health care center JUST covers an area of 13 664 brm2 with total volume of 60 600 m3. In addition to the center, a parking facility and a tunnel are built. The project is expected to be finished by the end of 2016. The planning and construction are executed using a new type of project alliance. The owner, facility user, planning team, and general constructor are all contract parties making the principles of open building implemented in use.
To ensure the co-operation between the parties and the diverse utilization of the information models, the project employs the VDC way of working (Virtual Design Construction), which was developed by the University of Stanford and is used in NCC as standard during information modeling. A virtual reality cave facility is in use, where the end-users have explored the JUST in virtual reality.
One Property in Two Phases
JUST is divided into two execution phases. In the first stage, (the phase of virtual planning and construction) a service provider put together a planning team and together with the owner they composed proposals, general design, and building permit plans. This was also a pilot project for Tekes, the Finnish Funding Agency for Innovation. In the ongoing second phase the property is being developed by the planning consortium, the contractor, and the owner together, according to the production implementation plan.
Using the full potential of BIM was clear aim for the project stakeholders. All participating disciplines modeled their designs. The model content are classified and analyzed to suit multiple uses. BIM was used in procurement enquiries, production planning, sectioning, site planning (Trimble SketchUp), cost estimating (Vico Office), schedule planning (Vico Office and Tekla Structures), task planning (Solibri) and quality assurance (Dalux). The aim is to develop new processes for utilizing BIM during the building lifecycle.
Fixed structures and transformable spaces
Building according to open building principles have brought on challenges to old and set new ways of working. For instance, the end-users have influenced on how the different rooms and spaces are situated. The fixed structures were planned and constructed separately from the changing spaces. Dividing the planning and constructions into separate sections allows for the still changing designs to be finalized with additional time schedule while fully designed sections of the building have been already delivered and installed.
The method has been unique in Finland and the implementation met the expectations with the help of NCC’s VCD team, long-term development, and clear BIM instructions.
BIM based design coordination has been a success, and the produced design are exceptionally free of errors and conflicts. Inaccurate plans have been a rare sight in the building site.
