Engineering company wins contract for Colne Valley viaduct

Colne Valley ViaductTaziker, an engineering company, has been awarded a contract by VolkerStevin to support the delivery of HS2 on the construction of the Colne Valley Viaduct in Buckinghamshire.

Taziker will be supplying, fabricating and installing the steel deck component of a temporary jetty structure which has been designed to provide access for the building of foundations for the new viaduct where it crosses a series of lakes. This is a key part of the first stage of works for the high-speed line.

The temporary jetty will consist of four separate structures with an approximate total length of 990m. 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.

“The construction of the viaduct in Colne Valley is a spectacular and essential part of the HS2 project. By supplying, fabricating and installing a major component of the temporary jetty, Taziker have the opportunity to show the quality and innovation we can deliver on major projects for major clients within our engineering division,” Jarrod Hulme, Managing Director of Engineering Solutions, Taziker said.

The viaduct, which will carry the new high-speed rail line for 3.4 km across a series of lakes and waterways on the north west outskirts of London, will be almost a kilometre longer than the Forth Rail Bridge and carry trains travelling at speeds of up to 200mph.

Engineers from HS2 Ltd’s main works contractor Align JV began work on the foundations earlier this year and Taziker is expected to begin work on site in June 2021.

Working on behalf of VolkerStevin for the Align joint venture, Taziker was awarded the contract following a competitive invitation to tender process. Align JV comprises Bouygues Travaux Publics, Sir Robert McAlpine and VolkerFitzpatrick and is the main works civils contractor responsible for the delivery of the C1 section on HS2. The C1 package of works consists of a 21.6 km stretch of high-speed rail infrastructure including the 3.37 km Colne Valley Viaduct, the 16 km twin-bored Chilterns tunnel and five ventilation shafts handling both intervention and tunnel ventilation facilities.
