Objection Management System for the Fehmarn Belt Fixed Link Tunnel


The Fehmarn Belt Fixed Link Tunnel (also known as the Baltic Sea Tunnel) will be the world’s longest immersed tunnel. Once open it will consist of a double-track railway and a four-lane motorway spanning a total of 18km. The tunnel’s construction currently represents the largest transportation project in Northern Europe and is one of the largest infrastructure projects in the world.

The tunnel will provide a direct connection between Germany and Scandinavia, as well as a train travel time between Hamburg and Copenhagen of approximately two hours and 45 minutes (previously four hours and 40 minutes). The travel time through the tunnel itself amounts to seven minutes by train and ten minutes by car. In the future, freight trains will save 160 kilometres by avoiding the overland detour across the Danish mainland.


Any mega-project can be met with objections, and the Fehmarn Belt Tunnel is no different. There are many aspects to take into consideration, from environmental issues to logistics and disruption to the public.

All these concerns need to be addressed with consistent responses for the project to pass its approvals, and an objection management tool is a necessity with a mega-project with lots of publicity.


Since implementing Document & Collaboration Management (FORMS & PROCESSES) combined with Virtual Design & Construction Management (VDC MANAGER), all identical arguments from hearings and planning meetings are answered uniformly with the same response. Thinkproject makes automated responses to identical arguments possible, which saves time while simultaneously ensuring consistency between responses.

All objections and statements received during the hearing phase will be collected in Thinkproject, divided according to individual arguments and subsequently assigned to the responsible processor. Each argument will be individually responded to and passes several approval steps within Thinkproject.
