The Helsinki-Tallinn tunnel project is gathering steam. The project, which kicked off before the turn of the millennium, has been given a cash injection as well as new impetus. A public sector study was conducted to analyze the project’s operational prerequisites, and AINS Group has joined forces with Pöyry and Fira to form a consortium, headed by Peter Vesterbacka, with a view to taking the project towards the planning and realization stages with the help of private funding.

In 2033, 15 years from now, people in Helsinki and Tallinn live in a twin city. The underwater railway tunnel has connected the two cities and revolutionized the commute. Finland is no longer an island: the tunnel offers us a super-fast connection to Europe.

The Helsinki-Tallinn tunnel is significant in many ways. The economic impacts during the underwater construction phase are massive. The huge project offers jobs for hundreds – or even thousands – of engineers, designers, suppliers and builders for 6 years.

Flow of people creates a twin city, boosting economic growth

The tunnel would create a fast connection between the two cities, offering people and cargo a new underwater gateway to reach the neighbour city in only 25 minutes. There will be new hubs with investment boom to feed increasing demand. People who are commuting via new routes need housing and services. This increases economic activity and demand not only in Helsinki and Tallinn, but also on the new artificial islands.

This is how a new twin city is born: Helsinki and Tallinn will be a metropole where people can easily choose the best place to live, study, work and consume products and services.

BIM and VDC in an important role in project management

BIM as a design environment and VDC as a project management process will be utilized in the project in a novel way. 3D Cave environment and a Big Room – concept will be in used for collaboration. Design management and value engineering will be conducted through BIM-tools and stereoscopic views. Experiencing information through visualization enables project stakeholders to understand the overall situation at any given time of the project.

Hundreds of risks, each of which needs to be managed

The boring of a tunnel under the sea between Helsinki and Tallinn is possible, but not free of risks.  We need to plan, schedule and design this project as rigorously as possible. We need to see as clearly as possible how to design the realization of this idea. BIM and VDC will both be essential tools in this work.

AINS Group has joined forces with Pöyry, Fira, and FinEst Bay Area Development to form a consortium that is planning the construction of the undersea railway link between Helsinki and Tallinn. If the plan becomes reality, it will result in a metropolitan area with two million residents. The 100 km tunnel would become the world’s longest tunnel.
