Vuorikatu 24 Hotel Building

Hotel Building

The site is located at the southern edge of Kaisaniemi Park, where a building used by the Finnish Meteorological Institute, constructed in the 1970s, was demolished to make way for a new hotel building. The client for this project was Jatke Oy.

The bedrock at the site was found at a depth of 2 to 4 meters. The area was very constrained; on the south side, a 5-story residential building is directly adjacent to the property boundary. To the east, the Kluuvi service tunnel lies 10 meters deep. Between the service tunnel and the excavation wall, there was only a 3 to 5 meter wide rock embankment. To the north, there is an east-west oriented sewer tunnel about four meters from the property boundary.

The demolition of the old building was completed at the end of 2020, and excavation work began in the spring of 2021. The excavation depth was 12 meters, and the excavation walls were reinforced by bolting and grouting. The excavation extended below the groundwater level. Ultimately, the amount of water seepage measured at the pumping station remained within permissible limits.

Due to the confined nature of the site, a working bridge supported by bored piles had to be constructed over the excavation on the west and south sides. A tunnel connecting to the service tunnel was built in the northwest corner of the excavation.

The building was completed in the fall of 2023.
