Mammoet at the mall

12 February 2018


Mammoet installed 16 steel girders for a new bridge linking the Dubai Mall to the new Fountain Views development.

Mammoet were contracted by contractor Eversendai to assist in the erection of the new bridge. The Fountain Views Link-Bridge will be home to retail outlets and provide a walkway to further parking.

The project constraints meant the crane needed to have a minimal footprint and low ground bearing pressure. Mammoet’s LR1750 crawler crane was the only available crane in the UAE that complied with all technical requirements. It installed the girders, weighing between 83t and 172t, in two sections.

The lifts were carried out on Sheikh Mohammed bin Rashid Boulevard, the main road that runs around Dubai Mall. With only two out of six lanes closed to minimise disruption to traffic, the crane had to manoeuvre in a tight space.

And there was another engineering challenge: water pipes underneath the area of operation supply Dubai Mall and the whole of Down Town Dubai. To avoid damaging them, it was imperative that the crane kept within the ground bearing pressure tolerance. Careful engineering calculations were made for the lifts to ensure that the LR1750 could lift the girders and manoeuvre in to place without nearing traffic, or going over the ground bearing pressure limit.

Mammoet installed the first set of girders on the Fountain Views side of the road. The whole operation was then moved to the mall side of the road where the other halves of the girders were installed, ready for connection in the middle.
