Prima Uno assisted on a consultancy basis for Transport for London to plan and cost the works which would contribute to the CTP programme.

Cooling the Tube Project (CTP) was a 5 year programme with a budget of £439 million. The programme is aimed to deliver cooling solutions with the LU Infrastructure or on its rolling stock and comprised of work covering; civil and structural engineering, mechanical and electrical equipment and systems, rolling stock and ventilation systems.

The Cooling the Tube programme has been established to implement solutions that will tackle heat on the LU network, both now and in the future. Higher heat levels are due to service increases (including planned line upgrades) and the consequent increases in energy consumption, which generates heat as a by-product. The problem is compounded by heat absorbed into the earth and clay surrounding the tunnel walls.
