King’s College London – Mulberry Campus
This development for King’s College London consisted the construction of student accommodation, a private residential ‘market’ block, and a new office for the administration of King’s College. The development abridged the Jubilee Line Tunnels which crossed diagonally through the site, and to reduce spans of the required transfer structure, 900 Dia. Bored piles were to be installed between the running tunnels.
The close proximity of the piles to the live running tunnels required in depth coordination with London Underground, and a detailed 3D ground movement analysis of the impact of the various construction phases of the project was undertaken.
Due to the depth of the concrete transfer structure required the design of a specialist concrete mix high in GGBS to retard the curing of the concrete and reduce the impact of earth thermal cracking.
The superstructure was predominantly designed using 225 thick concrete flat slabs supported on blade columns and was adjoined at first floor by a podium slab. The majority of the development was ‘at grade’, but a 4m deep basement was developed beneath the commercial building using contiguous piling and a waterproof concrete facing wall.
*This project was undertaken whilst at a previous practice with significant involvement from a Director at SD Structures.
