London Underground has awarded a £6 million contract to Mansell to carry out air conditioning works as part of the Cooling the Tube Programme.
The design and build contract covers the upgrading of Victoria Line mid-tunnel ventilation shafts. The job also involves environmental monitoring. The Balfour Beatty subsidiary beat three other firms to win the deal. The contract award indicated that works were likely to be sub-contracted.
The project is part of a wider effort by Transport for London to make the underground network more comfortable and less dangerous during hot summer months.
Cooling The Tube was unveiled by then Mayor Ken Livingstone in 2007, with £150m initially earmarked for the scheme.
In its budget for 2009/10 which was published at the end of March, Transport for London indicated that ventilation work on the Victoria line would continue through to 2010, with the installation of boreholes at Green Park station to be completed by February 2010.
These works are partly covered by the Mansell contract and the budget does not indicate the total amount of money that has been allocated to the Cooling the Tube programme, though it is likely to be well short of £150m.
Air conditioned trains for the Circle, District, Hammersmith & City and Metropolitan are expected to arrive in January 2010.
