MAMMOET AND EVERSENDAI PARTNER FOR DUBAI MALL EXPANSION CHALLENGE
Mammoet says that its LR1750 crawler crane was the only crane in the UAE capable of meeting the demanding requirements of the preparation work for the new Fountain 6iew Link-bridge, which is being built as part of an extension to the Dubai Mall.
Contractor Eversendai is overseeing the erection of the new bridge. When completed, it will connect the existing mall to a new section and help expand the number of retail outlets and provide a walkway to further parking.
According to Mammoet, the deployment of the crane faced a number of challenges after it was asked to complete the lifting and installation of the 16 steel girders that form the base of the bridge. Proj- ect constraints meant that the crane needed to have a minimal footprint and low ground bearing pressure and Mammoet’s LR1750 was the only available crane in the UAE that complied with all technical requirements.
With each girder weighing between 8 t and 172t and placed within two sections, the lifts were carried out on Sheikh Mohammed bin Rashid Boulevard, the main road that runs around Dubai Mall. Mammoet installed the lrst set of girders on the Fountain 6iew side of the road before the whole operation was then moved to the mall side of the road where the other halves of the gird- ers were installed, ready for connection in the middle.
With only two out of six lanes closed to minimise disruption to traflc, the crane had to manoeuvre in a tight space. Additionally, water pipes under the area of operation that supply Dubai Mall and the whole of Downtown Dubai provided a further engineering challenging.
“To avoid damaging them, it was imperative that the crane kept within the ground bearing pressure tolerance,” Mammoet said in a statement. “Careful engineering calculations were made for the lifts to ensure that the LR1750 could lift the girders and manoeuvre in to place without nearing traflc or going over the ground bearing pressure limit.”
