The bioenergy plant completed in Martinlaakso, Vantaa was a significant investment that supported Vantaa Energy’s goal of transitioning to using bio-based energy sources. In a little more than a year, reception centres, a screening building, two storage silos and a new conveyor line were completed at the Martinlaakso coal storage field, and a new boiler was built inside the plant. Kreate carried out foundation, concrete and infrastructure construction tasks flexibly on a tight schedule.
The project involved demanding excavations and concrete construction: the new boiler required an excavation of 700 m3, of which 500 m3 were excavated next to an operating turbine and near existing concrete pillars. The work at the coal storage field, conveyor tunnel area and inside and outside the plant also required lots of different materials: more than 300 drilled and driven piles, 5,500 m3 of concrete, 570 tonnes of iron and more than 2,000 m2 of sheet piles.
The project was challenging both in terms of schedule and engineering, which emphasised flexible labour and machine resource volumes as well as close collaboration between the customer, planning organisation and contractor. Vantaa Energy’s Project Manager Marko Lommi was happy with the smooth collaboration and Kreate’s work.
– It was easy to work with Kreate on this challenging project that involved various changes. The work progressed well and we were able to allocate additional resources for this hectic contract. Together we know how the costs of additional work are formed, and the crew performs very well under the tight schedule.
Kreate was responsible for the foundation, concrete and infrastructure construction for Vantaa Energy’s Marbio project. Equipment installations and other technical construction were carried out by the equipment and installation suppliers chosen by the customer. The customer was Vantaa Energy.
