VolkerStevin awards HS2 Viaduct contract to Taziker

VolkerStevin has awarded the HS2 Colne Valley viaduct construction works to the multi-disciplinary engineering specialist Taziker. This project in Buckinghamshire will supply, fabricate and install the steel deck component of a temporary jetty structure.

The structure has been designed to provide access for constructing foundations for the new viaduct. The 3.4km-long Colne Valley viaduct will carry the high speed rail line over a series of lakes.

The structure will be supported by 56 piers with spans of up to 80 metres long. This will allow carrying the railway around 10 metres above the surface of the lakes, the River Colne and the Grand Union Canal.

Four interior separate structures are available on the temporary jetty with an approximate total length of 990 meters. The works will also include safety barriers, pedestrian walkways and guardrails.

Thirteen additional working platforms will also be built to enable the construction of the cofferdams within the lakes, which in turn facilitate the construction of the permanent piers for the viaduct.

Taziker that’s working on behalf of VolkerStevin Align Joint Venture succeeds the contract following a competitive invitation to tender process. Align JV comprises Sir Robert McAlpine, Bouygues Travaux Publics, and VolkerFitzpatrick and is the main works civil contractor responsible for the delivery of the C1 section on HS2.

The C1 package of works comprises 21.6km of line including the Colne Valley Viaduct, the 16km twin-bored Chilterns tunnel and and five ventilation shafts handling both intervention and tunnel ventilation facilities.
