Strategically important railway project in Varberg.
On behalf of the Swedish Transport Administration, we are expanding the West Coast Railway with double track and a tunnel under the centre of Varberg. The contract covers approximately nine kilometres of double track, level crossings, new bridges, a new station and a new freight yard. All passenger and freight traffic on Västkustbanan is planned to be able to run throughout the construction.
Services in detail
The contract form is ECI with a Phase 1 and Phase 2. The contract includes the design and production of:
New freight terminal
Completion of the Lassabacke landfill
New bridge to Getterön
Concrete trough, submerged area, 900 m
New station with immersed platforms
Concrete tunnel, 300 metres
Rock tunnel, 2.8 km
Service and rescue tunnel alongside the mountain tunnel
New railway bridge over the Eastern route
New railway bridge at Vareborg
Storm water retention ponds, service roads, technical buildings and noise protection
Railway traffic for passengers and freight must be maintained throughout the whole construction period which requires detailed planning of various traffic phases.
High requirements on limitation for noise emission, vibration and structure-borne noise have to be observed, in particular within the urban area of Varberg, where the tunnel entrance has only a few meters of rock coverage.
In the north, the construction site adjoins a nature and bird sanctuary, which is subject to strict environmental regulations.
In confined areas of the construction field heavily contaminated soils require increased occupational safety measurements.
