Largest wooden school in Finland implemented sustainability with a life cycle model<\/h1>\n

The new wooden Mansikkala School in Imatra will be built in the middle of the school campus by the Vuoksi River. The project will be carried out by YIT using a life cycle model, and the components for the wooden frame will be supplied by Oiva Wood Solutions. Sweco handled the preliminary design, element design and main structural design of the structures for the largest wooden school building in Finland.<\/strong><\/p>\n

The wooden Mansikkala School is the largest investment in history for the City of Imatra. At the same time, it is an important step in the refurbishment of the school network, which involves a transition from the somewhat dilapidated small schools to three school campuses. Mansikkala is also a demonstration of the core values of the City of Imatra and concrete actions in sustainable urban construction.<\/p>\n

\u201cWe want to be responsible in terms of the climate and the environment at all levels of construction,\u201d says Lassi Nurmi<\/strong>, Managing Director of the City of Imatra\u2019s development company Mitra. Imatra will implement a large-scale solar power project, and excess industrial slag will be utilised in infrastructure construction alongside natural stone. \u201cEnergy-efficient geothermal energy will be used to heat and cool the new wooden school.\u201d<\/p>\n

Life cycle model also ensures systematic maintenance<\/h2>\n

Mansikkala School will be implemented using a life cycle model which involves YIT handling the maintenance for the coming 20 years, in addition to designing and constructing the building. Mansikkala is an exceptional project for YIT.<\/p>\n

\u201cThe school is the largest individual wooden building that we have implemented with the life cycle model,\u201d says Matti Varstala<\/strong>, YIT\u2019s Design Director for Life Cycle Projects. The life cycle approach steered all aspects of design. In addition to this, the funds that will be required for maintenance have been earmarked in advance. \u201cThe budgets of municipal operations are tight, which means that repair debt is easily accumulated. The life cycle model prevents corner-cutting in maintenance since the building must be handed over in the predefined condition after the agreement period.\u201d<\/p>\n

The biggest challenge with the life cycle model is taking multiple perspectives into account. According to Varstala, modern school buildings are complex and the technical systems alone require plenty of space and adaptation.<\/p>\n

\u201cWe aim to optimise everything as best we can and put together a building that is easy to maintain and reliable far into the future,\u201d he explains. \u201cSweco\u2019s designers have borne the main responsibility in terms of fitting together the varying needs and finding the right compromises. It\u2019s been challenging, but we\u2019ve made everything work.\u201d<\/p>\n

Wood element construction speeds up schedules<\/h2>\n

The school of some 16,500 floor square metres comprises two floors intended for teaching activities and the machine rooms in the attic. In the autumn of 2020, the new school will be admitting some 1,350 children and young people from day care children to upper secondary school students.<\/p>\n

\u201cAt the moment, we\u2019re focusing on modification engineering and ensuring that the end result is a high-quality building that meets the end users\u2019 needs,\u201d says Hannes T\u00e4htinen<\/strong>, Sweco\u2019s Wood Technology Manager. The school will be constructed using an adaptable module division, which will create clear lines and open spaces in the indoor spaces. \u201cVersatility is important in modern schools. Group sizes vary and the school also serves as a multi-purpose building for city residents and a meeting place for associations.\u201d<\/p>\n

Prefabricated wood and concrete elements have been used to construct the Mansikkala School. Concrete has primarily been used as a stiffening structure, and the intermediate floors, pillar beams and facade have been made from wood. The benefits of element construction are the high degree of prefabrication and the precision of even the largest elements. \u201cConstructing elements in controlled factory conditions as far as possible reduces time spent at the worksite significantly. It also ensures that the load-bearing structures are easier to connect to building services and automation,\u201d T\u00e4htinen says.<\/p>\n

The City of Imatra is now convinced of the benefits of wood element construction. \u201cIt has made a massive difference in terms of schedule,\u201d Nurmi says. \u201cWe\u2019ve been able to overlap design and implementation, finishing the module element installations of a building during the implementation planning of another, for example.\u201d<\/p>\n

Making wood construction commonplace like information models<\/h2>\n

The implementation of the diverse project on a tight schedule has required smooth information flow. The information model has been an essential tool for work task division.<\/p>\n

\u201cWhen everyone uses the same information model, the designers have fast access to the necessary information and production gets material specifications in advance, even though element design is still under way,\u201d T\u00e4htinen says. Sweco\u2019s SmartDrawings service was also used in the wooden element construction. \u201cProduction at the Oiva Wood Solutions factory could use a tablet to view the information model for the element to be manufactured and supplement the details in the manufacturing drawing.\u201d<\/p>\n

YIT\u2019s Varstala has no fondness for past times when information models were not accessible to everyone. \u201cThe school project has once again demonstrated the power of information modelling in merging different design areas and rooting out conflicts in advance.\u201d<\/p>\n

Varstala also hopes that wood construction will become more commonplace in the same way. \u201cAt the moment, public wood construction at this scale requires the client to have a strong desire to use wood specifically. However, wood construction has an immense amount of development potential, and all we need now is more successful experiences in the vein of Mansikkala to create a positive snowball effect. A change will materialise one project at a time!\u201d<\/p>\n
