The Landmark Tower
THE SECOND TALLEST BUILDING IN ABU DHABI
The Tower sits on a 5 storey deep basement measuring approximately 120 m x 150 m which extends across the full area of the site and beneath the road to south of the site. The basement comprises a temporary reinforced concrete diaphragm wall (not part of the contract) with a permanent reinforced concrete wall within. The internal wall is propped by the floor plates to resist the soil and water pressure. The floor structure is a reinforced concrete flat slab supported on 9 m x 9 m column grid. The columns are supported on a 900 mm thick raft slab with tension piles to resist uplift pressure. The main Tower structure is supported on 4 m thick raft slab which is tied intro the thinner 900 mm slab of the remainder of the basement structure. The tower itself measures 329 m in height from ground level and is comprised of a central reinforced concrete core containing the lifts and stairs, with perimeter round and blade columns supporting the 72 floors of main post tensioned floor plates. The columns and blade walls are predominantly in-sit reinforced concrete.
