Quay West Phase 2
Structural and Civil Engineering design on a development of three blocks of apartments to be known as ‘Waterside’.
The project forms the second phase of the popular Quay West development and provides a substantial five storey block built over the original basement structure along with two smaller three story block built off a podium deck over car parking below.
Each of the buildings is load bearing masonry construction supported on reinforced concrete substructure.
The riverside location provided challenges for both the structural design and the civils, with poor quality made ground beneath the brown field site and issues with flooding from the nearby river caused by both fluvial and tidal sources.
Foundations are piled using continuous flight augured (CFA) piles with individual pile caps and ground beams as required. Accommodation is kept above the risk of flooding, and the ground floor is used for parking only.
Ground levels are designed to encourage overland flooding back to the river channel, where specially designed flood chambers allow water off site whilst preventing tidal ingress. The boundary wall has been designed to withstand tidal surges with a 1 in 200 year likelihood, and surface water drainage is attenuated on site to accommodate tidal lock where the surface water is prevented from entering the river due to high sea levels.
