A large parkade and bridge form the base of a landscaped area at the entrance to the Mall of Africa in Waterfall City, a 330-ha mixed use commercial estate in Midrand, Gauteng.
4 000 m² bridge with architectural steel enhancements. Each end of the bridge had a 3 m overhang. At the one end, the overhang had to be supported from the parking slab and at the opposite end, it had to span a 4.5 m embankment of sloping soil, which was not suitable to deck from. The adjacent 40 000 m² parking structure included a transfer slab at the top level which had to be able to carry a 1.5 m soil filling, so that the client could create the grass terrace on top.
PERI has an excellent design and technical support team.
MULTIPROP towers and steel beams that rested on top of concrete plinths which had to carry 200 kN. 5 000 m² of PERI MULTIFLEX, including plywood was used for the transfer slab. The support consisted of a line of QUICKSHORE towers under the downstand beams.
