Abu Dhabi’s Corniche is set to feature the Emirate capital’s second tallest building as construction gets underway on a 324 m high tower; with five Liebherr tower cranes being used throughout the initial phase of construction.
At the top of the 72-storey tower a concave steel structure 52 m high and reducing to 7.3 m height on the opposite side of the roof, will be installed in-situ; with an external climbing Liebherr 160HC-L 8/16 Litronic luffing jib crane being used for lifting the 2-10 t elements.
In order to undertake lifting duties for the structure a distance of 52 m from the last tie-in to the cranes slewing platform was specified to ensure an acceptable ‘over-standing’ height.
Each of the three luffing jib cranes including two internal climbing units, have a maximum lifting capacity of 16 t and feature 50 m jibs. Luffing jib cranes were chosen by the contractor for their speed of lifting on narrow sites allowing lifting and lowering.
The second crane has a 70 m jib length and a 43 m hook height from the ground level.
The basement structure extends across the full width of the site and beneath the old Corniche Road next to the site.
