The conversion of an island into a residential area continues in Nihti. The fourth phase of the project covers the preconstruction of the southern area for the construction of the actual residential buildings. The project includes the construction of streets, municipal infrastructure and shoreline structures, the dredging of coastal areas, rockfill and the demolition of old quay structures.
The work started in July with the fencing of the area and the construction of the work site base. The installation of the silt and bubble curtain will start in the week starting on 4 August, followed by dredging the following week. The area will also be cleared of vegetation and old asphalt will be removed.

The noisiest work will be carried out on weekdays between 7:00 and 18:00
Transport of soil will increase heavy traffic in the area
Contaminated soil has been found in the area and is being transported away in covered loads to protect the environment.
The project requires transporting aggregates and materials, among other things, to the construction site. In addition to this, soil and other waste materials will be transported away from the site throughout the project. This will increase heavy traffic in the area.
For the time being, site traffic will not cause any changes to traffic arrangements.
The contractor responsible for the preconstruction of the area is Skanska Infra Oy.
