Mammoet assisted the construction of the iconic UAE Pavilion at Expo 2020
Project scheduling minimized disruption to other work on congested site.
Dubai Expo 2020, currently hosted in the United Arab Emirates, is a six-month event showcasing architecture, global culture and innovation that will bring together participants from 192 countries and six continents. The theme of the Dubai Expo is ‘Connecting Minds and Creating the Future’ through sustainability, mobility and opportunity.
The Expo includes some of the most innovative ideas in architecture and design today – among them UAE Pavilion, one of the Expo’s greatest icons; having both national and global significance. Designed by Spanish architect Santiago Calatrava and inspired by his observation of a falcon in flight, the UAE pavilion tells the history of the nation as a connected global hub, and the vision of its leaders to create a peaceful and progressive society with ambitious plans for the future.
Located at the centre of the 200-hectare exhibition zone, the UAE Pavilion is set on an area of 15,000 square meters. The 28 movable wings of the falcon represent the flow of movement. The ‘wings’ can spread open within three minutes, covering a range of 110 and 125 degrees.
Installing the ‘wing’ panels
Mammoet deployed one of its 750t crawler cranes – Liebherr LR 1750 to lift and install the ‘wing’ panels of the UAE Pavilion roof. The weight of the panels ranged from 6t to 16t with lengths varying between 24m and 61m.
Due to the size of the panels and a large surface area to weight ratio, the permissible lifting wind speed was reduced to 3.4 meters per second to ensure safe operations. All panels were installed at night to accommodate the continuity of other construction activities at the UAE Pavilion during daylight hours.
Each panel was lifted at an outreach of 35m with the counterweight disconnected to accommodate the congested site requirements. After slewing the panel above the roof in line with the installation position, the counterweight was connected so the crane could boom out to 117.5m with sufficient capacity. Each panel was then safely lowered down to enable easy alignment for further securing.
Additionally, six mobile cranes – ranging in capacity from 50t to 350t – were deployed for installation of various structures at the Expo site, including bridge portals and the public spaces in concourses and arrival plazas.
The Dubai Expo 2020 has recorded over 10 million visits since its opening on October 1, 2021.
