City Campus comprises a 7 storey block, an 11 storey spine tower, and a 4 storey wing. A steelwork frame carries precast concrete floor slabs. Robustness anchorage is provided by reinforced in situ concrete topping. RVK101 telescopic connectors supported precast concrete stair landings on pockets in the concrete stairwell walls. RVK connectors also provided a horizontal structural connection between landings and walls, giving stability where service voids prevented tying. Modified RVK101 connectors were developed which supported the stairs and gave a 30kN axial capacity. Anchorage provided by modified RVK101 connectors solved a major design problem with very little additional cost.
