CASE STUDY

Quay House, Liverpool

The building is immediately surrounded by highways on all elevations, and this, together with 5 metres of fill material in the ground, provided considerable design challenges for the basement car park. Our solution utilised sheet piling to retain the highway and to take the vertical load from the superstructure into the bedrock.

The economic requirement to provide sufficient car parking in the basement for all apartments necessitated the majority of the residential floors to be supported on the basement roof, to allow free-flowing  traffic movement. Disproportionate collapse, therefore, presented significant issues.

Lateral stability was provided principally by the reinforced concrete core forming the lift shaft and stairwell, with careful consideration being given to the asymmetry of this unusually shaped building.
