We are the construction consultant for the rock construction of the new, energy efficient wastewater treatment plant to be built in Blominmäki, Espoo.
After its completion in 2020, the new plant will replace the current Suomenoja wastewater treatment plant, at which point the wastewater of around 400,000 residents in Espoo, Kauniainen, Kirkkonummi, Siuntio and Western Vantaa will be treated there. By 2040, an estimated 150,000 cubic meters of wastewater per day is estimated to flow through the new treatment plant.
We acts as the client’s developer consultant. At the excavation stage, the company will handle the duties of the developer consultant’s project manager and project engineer, site supervision, and safety coordination.
The demanding and multifaceted nature of the project necessitates a daily site supervision presence on the work site.
The excavation of the Blominmäki wastewater treatment plant involves around 870,000 cubic meters of underground excavation, around 100,000 cubic meters of earth excavation and quarrying, several shafts and four large fermentation chambers. The project also includes a large amount of reinforcement and compacting work. The project is estimated to involve 1,800,000 drilling meters of grouting holes, with 1,650,000 kilograms of cement used in the grouting. Around 90,000 reinforcement bolts will be installed in the facility. The project also involves demanding reinforced concrete structures.
