The final piece of the Al Wasl dome designed by American architecture firm Adrian Smith + Gordon Gill Architecture. has been lifted into place, representing a significant milestone in the construction of the centrepiece of the Expo 2020 Dubai site, Arabian Business reported.
Enclosing a space of 724,000 cubic metres and standing 67.5 metres tall – higher than the Leaning Tower of Pisa – the 130-metre-wide domed steel trellis encircles Al Wasl Plaza, a structure that will be the heart of the Expo 2020 site.
During Expo 2020, Al Wasl dome will be the largest 360-degree projection surface in the world.
Weighing 550 tonnes of moulded steel, Al Wasl dome’s 22.5-metre crown had to be precisely positioned on top of the vertical trellis, with a margin of error of only three millimetres.
