The area at Penttilänranta has been divided into three separate areas according to old use, future use, and repair goals. The old log basin contained contaminated sediment and it was renovated into a marina by suction dredging. An old landfill area was restored into a scenery area and industrial properties by encapsulating.
The large sawmill area (25 hectares) changed into office and living space by soil replacement and by demolishing the old structures.
Sito functioned as the project management consult for repairing the polluted soil at Penttilänranta. The main tasks for the project management consult are preparing and organizing the bidding for acquisitions, reporting the acquisitions to the city, guiding planning and work, and getting supervision.
The repairs were carried out according to the quality control model for environmental projects. Approximately 1,000,000 tons of polluted and clean soil and sediment was moved in the area. 95 % of the polluted land was directed to reuse according to the quality control model.
