Balfour Beatty VINCI is responsible for designing and building part of the most exciting and challenging railway project in Europe: HS2.
We are building the West Midlands section of HS2’s Phase One route, spanning approximately 80km from Long Itchington in Warwickshire to the centre of Birmingham and on to Handsacre in Staffordshire.
We will be employing thousands of people in the area to design and build the civil infrastructure for HS2 through the West Midlands area.
- 42 viaducts totalling over 11km, 66 overbridges,
- More than 35 cuttings reaching over 30km
- 56 culverts and other underbridges
- 66 embankments reaching over 33km
- Building four motorway crossings requiring box structures and six interfaces with the existing rail requiring both dive-under and overbridge structures.
Works included the installation of substation buildings, switchgear and associated ancillary equipment as well as integration testing and commissioning in conjunction with Network Rail. To minimise disruption to services using existing infrastructure, we clearly defined our commissioning strategy at an early stage to ensure full integration between design, construction and commissioning works.
West Outer Electrification and Track Infrastructure works (Balfour Beatty)
- The ‘auxiliary track’ technique – an 8km track made up of 18m decks with wooden sleepers
- The ’pusher wagon’ technique – the works train travels on the track it is laying with the ‘pusher’ wagon carrying the track into position and pushing it forward, a ‘spider boom’ then places the track onto the sleepers
ElecLink interconnector (Balfour Beatty)
The first 1.4km of the 5.5km long scheme passes through an urban area along the path of an abandoned railway line. The remainder runs through rural areas of high profile environment and diverse ecology as well as public amenity. The complex engineering and innovation required to construct this road though flood plains and poor ground conditions were shortlisted for ICE Engineering Excellence awards.
This project rewired the capital via deep underground tunnels, in order to ensure London’s electricity needs continue to be met and that the city can access the renewable energy sources of the future. The project connects several substations around the city via tunnels at depths of up to 60m below the surface.
The project replaced an existing 132kV overhead transmission line that was dismantled during the contract period with existing sites reinstated.
