Keller will provide compensation grouting works at London Underground’s Tottenham Court Road and Bond Street stations.
Work involves the installation of 50 kilometres of pipe through which grout will be pumped while tunneling works are in progress to mitigate any ground movement and protect the existing infrastructure.
Keller has also been awarded a contract for structural monitoring, geotechnical instrumentation and surveying works using the firm’s new Getec system.
Work on both contracts will begin shortly and will run through to 2014.
The awards are a significant boost to Keller’s UK business which “has faced extremely challenging market conditions in recent years”.
Underground stations have been a major source of work for Keller following a £37m award in June for grouting works for the Victoria Station upgrade, which will start in late 2011.
Justin Atkinson, Keller Chief Executive, said: “Major infrastructure projects such as these, requiring complex solutions, play to our strengths as a global, high-capacity provider.
“These three contracts, which will draw on combined Group resources and our considerable experience of large-scale tunnel stabilisation projects around the world, demonstrate the synergies between our businesses, particularly when it comes to co-operation on large projects.”
