Barhale has achieved the breakthrough of a 330m long tunnel under the Thames from Chelsea to Battersea Park for a new gas pipe for Cadent.
The tunnel forms part of gas distribution firm Cadent’s £1bn programme to replace aging infrastructure in the capital.
Tunnelling work by Barhale took just over three weeks to complete and saw around 4,500m3 of material excavated.
The firm sunk two 30m shafts for Skanska Civils – part of Cadent’s strategic partner tRII0 – which also includes Mott McDonald.
Andrew Hejdner, Project Manager for Cadent, said: “This is a key infrastructure project. It’s a major commitment by Cadent and will guarantee gas supplies and help ensure that London remains one of the world’s leading cities.”
The TBM was controlled remotely by an above ground operator to carve out the 330m long tunnel.
Ovi Frunza, Barhale contracts manager, said: “As the tunnel was the deepest pipejack ever attempted under the river Thames, specific measures were put in place to mitigate for the ground conditions and confined environment of working in central London.”
