The expansion of Jubilee Place was one of the UK’s largest retail expansion projects, creating 50,000ft² of new retail space beneath the existing Jubilee Place Mall at Canary Wharf, London.
Canary Wharf Contractors appointed Kilnbridge to undertake major structural alterations to the existing car park, which involved extensive concrete cutting and reconstruction to transform the existing car park level to retail space.
The solution involved the cutting and lowering of the car park slab onto new sleeper walls constructed two metres below and the design and installation of a hydraulic system which lowered pre-cut slab sections each weighing 67 tonnes onto the walls beneath. Beam strips were maintained during the operation to support the pre-cut slab loads and were then cut and lowered to the required level. The slabs and beam strips were then knitted together with a concrete topping screed and new connections into the existing columns.
The project also removed a primary support column underneath the centre of Canary Wharf. This necessitated the installation of new structural members (5-11T per beam) two levels below the existing operational retail area without the use of any mechanical means for moving or lifting the beams. This was followed by complex load transfer procedures to maintain the stability of the structure.
Additional and extensive structural alterations were carried out which involved the modification or removal of existing lift shafts and escalators and installation of new lift shaft structures. Delivering this project required the creation of bespoke solutions for both the handling and load transfer operations at each location where new steelwork was being installed.
