Helsinki – Growing inside the Bedrock

Helsinki – Growing inside the Bedrock

As the city’s structure becomes more dense, more and more facilities suited for different purposes are being built underground, if possible. There is also a growing need to connect the premises to each other to form coherent and interrelated complexes. Since the 1960s more than 400 of those already have been built underground in Helsinki. More than 200 reservations exist for long-term underground projects. Demand for underground facilities has grown considerably and, at the same time, the need to control construction has increased substantially.

The Underground Master Plan of Helsinki, having a legal status, reserves designated spaces for public utilities and important private utilities in various underground areas of bedrock over the long term. The Master Plan also provides the framework for managing and controlling the city’s underground construction work, and allows suitable locations to be allocated for underground facilities.
