Circle Square Car Park – Manchester

Circle Square Car Park – M1 7ED

Fielden Clegg Bradley were concept architects while Leach Rhodes Walker were delivery architects.

A series of four × two-storey-deep lattice girders and a single one-storey girder, all measuring up to 27m-long, span over the zone where the underground pipes are located. In these parts, the car park has no first-floor level as the local water board needed a 5m ground-to-ceiling clearance in case they had to undertake any maintenance works. Consequently, the first floor is only a partial level and is set within the depth of the larger lattice girders, as is the second floor, while the third level is supported on top of these members.

Supporting a hotel would be challenging enough, however the design has also had to incorporate large bridging elements as there are two subterranean 600mm-diameter water pipes crossing the site. “It’s a very unusual design and one that was originally designed as a concrete-framed structure,” says James Killelea Senior Structural Engineer Charlie Twist. “However, the bridging parts would have proven to be too difficult to build and consequently a steel-framed solution was chosen for the car park, which in turn supports a precast concrete hotel.”

This car park is one of the cleanest and most well maintained in Manchester.

What a refreshing change for the pedestrian in a car park!
