Case studies
Nakheel Tower, Dubai
Repute has been used by
Golder Associates (Melbourne) for
the foundation design of the Nakheel Tower in Dubai. With a planned height
of over 1 km and a dead weight in excess of 2,000,000 tonnes, the tower was
planned to become the world’s tallest building. The project was placed on
hold in 2009 when about half of the foundations had been constructed, and
construction is yet to recommence.
The foundation system consists of a raft with a thickness that varies up to a maximum of 8m supported by a total of 392 barrettes. The barrettes have sizes of 2.8m x 1.2m and 2.8m x 1.5m and extend to depths of 37m, 42m and 72m below the carbonate cemented siltstone where the base of the raft is to be founded. Numerical analyses including the software Repute were performed by the designers in order to control the tower settlement and tilt, and the load distribution in the barrettes.
Further details on the foundation design may be found in the papers by Haberfield & Paul "Footing design of the Nakheel Tower, Dubai, UAE" (In Workshop on soil-structure interaction and retaining walls. Proceedings of the Technical Meeting TC207-ISSMGE, Dubrovnik 2011, pp. 35-52) and by Haberfield "Practical application of soil structure interaction analysis" (Proc. 19th Int. Conf. on Soil Mechanics and Geotechnical Engineering, Seoul 2017, Honour Lecture, pp. 81-99).
