Precast concrete products from Milbank were chosen for the redevelopment project of the Kia Oval, a historic cricket ground, conference and events venue in Kennington, South London.
Milbank were responsible for the design, manufacture, delivery and installation of over 700 precast components, consisting of terrace units, stairs and gable and vomitory walls, leading to the completion of the new stand which has a capacity of 6,300 seats, increasing the grounds overall capacity to 25,000.
Due to the oval structure of the stadium, each tier of terrace units was a different length and had splayed ends to form the desired circular layout. The low gradient of the terrace resulted in a small riser height in each tier, and required deep downstands. 480no terrace units were provided in total, with the inclusion of over 200 individual precast concrete step units for the circulation areas.
The five vomitory areas included a range of precast concrete walls up to 4.3 metres high and stair units with 13 risers, 1390mm wide, to enable access to the terrace from the concourse. The stairs had integral top landings resulting in them being over 5 metres long with each weighing over 4.5 tonnes, more than twice the weight of a 2018 Range Rover Autobiography.
Precast walls were also provided to the camera pit area and also to one gable end of the stand. These had to be specially designed to hang off the side of the structure. In total, Milbank provided over 80no precast concrete walls.
