With the Switch House sharing its foundations with the existing Turbine Hall and the new building’s tower oversailing the Switch House, settlement was a key consideration for the Ramboll geotechnical team, especially with the Turbine Hall glass roof. Movement posed a critical issue and was a key driver in the development of the foundation design for the new building.
Extensive work went into tying the foundations together. Access was limited at this stage, as the Switch House piles were installed prior to any demolition on site.
The architectural intent for the original oil tanks was to remain in their current condition, in order to recognise the industrial heritage of the site. Movement of the tank walls was closely monitored during the works, to ensure that they could be converted in the future into a highly-controlled environment of art spaces.
