Beetham Hilton Tower
wins Concrete Society Award
Beetham Hilton Tower, Manchester was a winner in the Building category of the prestigious Concrete Society Awards - Excellence in Concrete 2007. The Beetham landmark is the tallest concrete frame ever constructed in the UK, a project with which BRC is proud to have been involved as the main steel reinforcement supplier.
The tower is a mixed-use development consisting of a 279-bed Hilton hotel, public bar and 219 apartments, all housed within its 47 storeys. The building itself is over 170m in height above ground level.
The structure of the building is made up of two vertical cores, with post-tensioned slabs being used to maintain minimal slab depths and give greater spans between columns. Concrete was used to construct the frame due to its superb acoustic resistance and good fire protection.
Concrete made the building possible in many ways, even though the design is based on concealing how it is done:
- 200mm post-tensioned slabs minimise storey heights and give big bays; they also allow apartment owners to cut through and join floors
- oval columns in the base are fair-faced concrete and sleekly done
- cladding to the podium block is in a precast polished concrete with a dark, terrazzo-like finish, matching the glazing in sophistication.
The construction process used pump-placed high strength concrete (80 and 60MPa) for all floors. An innovative idea, with over 2m3 in the pump line, was to discharge the concrete at the end of the day’s pour into formwork to make precast stairs for the works, which avoided waste.
