The construction of the Luostarinkylä interchange is under way.
The construction of the Luostarinkylä interchange is under way. The clients are the Finnish Transport Agency and the Town of Rauma. Among other elements, the interchange includes bridges over National Road 8, National Road 12, the railway and a raw-water channel.
“The interchange will serve the Lakari industrial and logistics area. It will connect the northern ring road and the north-eastern main road, meaning that it will also benefit traffic in Rauma on a more general level,” says Project Manager Kari Partiainen from the Finnish Transport Agency.
The project budget is EUR 12 million. Of the total, 50% is provided by the Town of Rauma and 25% by the Finnish Transport Agency. The remaining 25% is covered by means of support for urgent structural change by the local Centre for Economic Development, Transport and the Environment.
Destia is responsible for the planning and implementation of the project. The building contract was signed in April 2015, and the work began soon after that. The interchange is expected to be completed in November 2016.
“Unlike other contractors, Destia is capable of carrying out the final construction planning as well, which accelerates the work,” says Partiainen.
The project schedule has created some pressures, as the funding granted by the Centre for Economic Development, Transport and the Environment required the work to be started during 2015.
Project Manager Eetu Väisänen points out that the in-house design engineers are familiar with the company’s fleet and other resources, which enables them to choose the right working methods and work sequences as early as the planning phase.
“Besides, it’s easy to consult an in-house design engineer whenever necessary, even with concerns that may seem minor,” says Väisänen.
The project is being designed and constructed using Building Information Modelling (BIM).
Destia and the Finnish Transport Agency are pioneers of BIM-based construction in Finland. This construction site is a pilot project where the method is being implemented more extensively than ever before in the country. Destia is also collecting experiences for the future.
In BIM-based design, a 3D design system is used to produce a continuous model. It can be examined and sectional drawings can be produced from any perspective. The model is continuously added to during planning.
