Tyne Tunnel wins top civil engineering award

Recent

The €296 million New Tyne Crossing, completed in November 2011, has taken the top civil engineering gong at the British Construction Industry Awards in London.

The judges said the project, on which VolkerStevin Marine was contracted to manufacture, transport and immerse the tunnel units, was "a demanding, challenging and highly complex project which epitomises excellence in safety, quality, design, innovation and community relations."

Tyne Tunnel

Tunnel

The New Tyne Crossing won the Major Civils Project Award (over £57 million) for the whole crossing. This comprised a new 1.5km tunnel and a major refurbishment of the existing 1960s built Tyne Tunnel to provide two traffic lanes in each direction and a threefold increase in capacity. Specialist contractor VolkerStevin Marine completed the contract for the manufacture, transportation and submersion of the tunnel units using immersed tube technology.

River Tyne

The contract involved the construction of four 90 metre long split sections of rectangular pre-cast and reinforced concrete tunnelling, which are 8.5 metres by 15 metres in size and altogether required 14,400 cubic metres of concrete. These units were then floated down the River Tyne, before being submersed on to the river bed in exactly the right place at exactly the right angle to create the new tunnel.
