The ceremonial masonry stone was laid today. The new building will replace the previous City of Helsinki Public Works Department by Kasarmitori square.

“The revitalisation of Kaartinkaupunki is one of the major focuses for Helsinki city planning due to its central location, historical surroundings and tourist routes. We are very pleased that the new high quality office building has been designed to sit naturally together with other prime properties on the square”, says Pekka Sauri, Deputy Mayor for Public Works and Environmental Affairs in Helsinki, in his ceremony speech today.

While building amongst houses from different eras in the busy city centre both architectural and construction specific technical solutions have to be adopted in the planning and development of the building.

“In order to find viable solutions we have needed experienced developers, competent builders and most of all, seamless co-operation to reach our goal”, states YIT ‘s CEO Kari Kauniskangas.

The newbuild project has proceeded as planned, the demolition was completed during the summer and the blasting and groundworks have commenced according to schedule, the blasting to be completed already in August-September.

“After the cornerstone is set in the construction, we will start with the basements. The excavation will be 10 metres deep and will consist of two basement floors. The lower basement will consist of a ventilation plant room and a service space, and the other one will be a parking hall”, says Tero Ahonen, YIT´s General Foreman.

“The frame of this office building will be erected in October and the first floor will be seen from the edge of Kasarmitori in November.  The floors will be completed at the pace of one floor per month. In January 2017 we will start installing the façade in natural stone and installing the first floor windows, which means that the façade is a couple of floors behind the completion of the frame”, continues Ahonen.

“All seven floors of the new building will be completed in April and the first tenant is moving in at the end of 2017.”

“The deviant traffic arrangements by the Kasarmitori surroundings remain until the very end of this project. They have functioned smoothly so far”, states Ahonen.

The project will employ 40-50 YIT employees and a large number of contractors and consultants. The project impact on employment is estimated at up to 400 person-years.
