UAE-headquartered Al Faris worked on the Expo 2020 Stadium in Dubai, UAE, lifting and installing 42 structural steel elements for the construction of the UAE pavilion structure.
For the first stage of the project, Al Faris lifted and installed structural steel elements ranging between 24 metres to 46 metres in length. The weight of the units ranged between 8 tonnes to 55 tonnes. To do this Al Faris used its Liebherr 1000-tonne LR11000 crawler crane. It said it selected this crane due to its long working radius.
Al Faris then used its Liebherr 750-tonne LTM1750-9.1 all-terrain mobile cranes to lift and install the Oculus structure at the centre of the UAE pavilion roof.
All surveys, planning, technical support documentation, execution plans and schedules were prepared in-house by Al Faris prior to job execution. This, it said, helped organise all activities smoothly with minimum delays.
On-site challenges included: restricted space in which to set up, operate, and dismantle the crane; a tight schedule in which to carry out the job; strong winds; and the structures had to be lifted at a specific angle, which impacted the selection of the lifting equipment. In addition, Al Faris had to fabricate steel mats to maintain ground pressure.
Despite these challenges, Al Faris reports that the job went smoothly and safely.
