This paper presents the experiences in design and construction of the foundation of a nine-story high quality new office building with an area of more than 40,000m2 over the platforms and railway tracks of Charing Cross Station in London. Both the severe constraints of the site conditions and the requirement that railway operations should always be kept normal during construction period led to great difficulties in design and construction. In the paper, the comparison of foundation alternatives. the design approach and calculations, the ground movements assessment, and the main construction method are described in detail.
