The economic regeneration of London South Bank area requires a better transportation network for local business and residential communities. As a part of the transformation plan, London Underground's Northern Line was proposed to extend into Nine Elms and Battersea with the requirement for two additional stations. This paper discuss the recent innovations adopted in foundation construction for Battersea station, to manage challenges in delivering the project. A trial pile, supported by polymer slurry, was constructed prior to the main piling work. This helped to build up the knowledge and confidence to construct the largest piles to be supported by polymer fluids in the UK. The paper also includes the successful use of Distributed Temperature Sensing (DTS) technology in assessing the integrity of the pile as well as capturing the dynamic tremie concrete rise.
