Work to cool the platforms at two major central London Underground stations is set to begin next month, Transport for London has announced.
Contracts have been awarded to Morgan Sindall and Balfour Beatty subsidiary Birse to start work at Green Park and Oxford Circus stations. Part of the accelerated Cooling the Tube programme, work will start next month and must be completed by this summer.
At Green Park station borehole cooling technology will be used. London Underground has already successfully drilled wells to source naturally cool water from deep below Green Park and Morgan Sindall will now install air cooling units that will use the water to cool the Victoria and Piccadilly line platforms.
At Oxford Circus station there are already air cooling units in the ticket hall however they will now be installed on every platform for the Bakerloo, Central and Victoria lines. The new units will use cool air provided by chiller units that will be installed on top of a building owned by Transport for London, which is adjacent to the station.
Morgan Sindall’s contract for work to install eight air cooling units at Green Park is worth around £9M. Birse Metro has not disclosed the value of its contract to install 14 air cooling units as well as associated construction services at Oxford Circus.
The work will be project managed by London Underground.
