The E4 Förbifart Stockholm is a major transport infrastructure project located to the west of central Stockholm. The new motorway section extends approximately 21 kilometres, of which around 18 kilometres run through tunnels, making it one of the largest and most technically demanding road projects in Sweden.
The scheme comprises three lanes in each direction and six interchanges. Upon completion, it will significantly enhance north to south connectivity across the Stockholm region and is set to become one of the longest road tunnel systems in the world.
Construction is being carried out under the supervision of Trafikverket and is divided into multiple delivery contracts and phases. The project represents a highly complex tunnel and motorway system, with demanding requirements for technical systems, safety, multidisciplinary coordination, logistics, and operational reliability. As such, it stands as a valuable reference project for organisations involved in its delivery.
Project Scope
On behalf of L.Tech Slovakia, we are responsible for the installation of the complete water based fire protection system within the E4 Förbifart Stockholm project.
Within the tunnel sections, a deluge sprinkler system is being installed, designed to provide rapid and effective fire suppression in critical infrastructure environments.
The scope also includes the installation of more than 1,000 valve stations and several kilometres of piping infrastructure.
