Olympic Stadium Greenwall
At the Olympic Stadium two types of live greenwalls had to be designed and installed. The first was a 6m high 500 linear metre long wall which ran around the perimeter of the stadium embankment, the second a near vertical green screen around the stadium entrance. Both presented different challenges.
The embankment screen had to be planted and installed near the water’s edge, against a 70 degree slope and on a sloping substrate. Planted into the embankment were 20,000 plants, each required a separate irrigation feed.
We developed a system of modular falsework which could be simply erected and relocated to create a lightweight working platform. This approach was also carried through into the maintenance strategy to develop a mini-gantry using the same principle that could be safely utilised by the legacy team in maintaining the planting. The Olympic Stadium “green” screen consists of a 5m high ivy wall, which frames the entrance to the Stadium. The main constraint for this design was that there was no secondary support provided to fix the 3 tonne screens, which slope and curve in two planes.
Willerby Landscapes designed and fabricated a cantilevered steel structure which was modelled using 3d software to detail the secondary frame to provide a tailor made support to the screen.
