The construction project Signe enters blasting work phase

The construction project of the new Signe building enters the blasting work phase in May. The blasting will start during the week starting with 20 May 2024 and will be completed in October at the latest.

  • Blasting operation in compliance with the noise permit will be conducted from Monday to Friday between the hours of 7 and 18.
  • Loading and transportation of the blasted rock will take place from Monday to Friday between the hours of 7 and 20 and possibly on Saturdays between 8 and 16.

There will be a warning sound prior to each blasting event. The following times have been reserved for blasting during weekdays:

  • 9:00–9:10
  • 9:49–9:59
  • 12:30–12:40
  • 13:50–14:00
  • 15:20–15:30 and
  • 17:30–17:40.

We have planned the work to cause as little inconvenience as possible to those living, working and moving in the area. We will have earplugs available for those who want them, which can be picked up from the site office at Yrjönkatu 23 b (4. floor). To keep noise to a minimum, we use the quietest machines available. Wherever possible, the machines will be placed in such a way that their noise will be heard as little as possible in the nearby premises.

The blasting work has been subcontracted to Kreate Oy by the main contractor Jatke Toimitilat Oy.

The entrance to the site is located at Mannerheimintie 16 and exit in the crossing of Kalevankatu and Mannerheimintie. The gates to the site have traffic controllers that control the traffic as well as the movement of walkers and cyclists, when necessary, to ensure their safety and the smooth flow of traffic.

The amount of noise from the site at different stages of the project

Demolition work goes on at the Signe site until the end of September and the earthworks and blasting until the end of October. These stages are the ones to cause the most noise throughout the project.

  • The frame construction from October 2024 to September 2025 as well as the facade work from April to December 2025 will cause less noise than the earlier phases of the project.
  • As of December 2025, only the building’s interior works will be in progress, causing only little noise.
  • The building will be completed in the autumn of 2026.

The noisiest phases of the project will end at the end of October. After that, the site will generate less noise, so it does not require, for example, a noise permit issued by the authorities.
