A new iconic tower in the heart of the Dubai Marina

Reaching a remarkable height of 365 metres, Ciel Tower in Dubai Marina is a stunning development that will set a new global benchmark as the world’s tallest hotel upon completion. As the world’s tallest hotel, Ciel Tower is set to become one of the region’s most famous buildings with its property’s incredible rooftop glass observation deck. Ciel Tower features a striking design, contemporary interiors and a remarkable glass observation deck, which will offer incredible 360-degree vistas across Dubai Marina, the Palm Jumeirah and the Arabian Gulf.

The work site is closely surrounded by existing structures, including a critical RTA bridge crossing the canal.

Zetas has been contracted for the Enabling Works, and entrusted Sixense with the instrumentation and monitoring of the ground and the structures in and around the site. Dutch Foundation, later contracted for foundation changes, recognised Sixense’s track record of delivering success for the project, and kept them on board for future works.


A complex situation on site

The instrumentation & monitring system was set to achieve the following:

  • safety during and after the construction by providing early warning of any excessive and undue movements of adjoining premises/structures/utilities
  • to provide settlement, deflection and deformation data for the verification of the initial design of the permanent structures and the temporary works supporting the excavation
  • to provide information on ground movements to ensure that the tolerances associated with various structures/elements within the zone of influence are not exceeded
  • to estimate and monitor the expected ground movement during construction

Sixense has also been providing periodic monitoring data reports, and have granted the contractors, consultant and RTA with live access to the monitoring data through its Web-based GIS software Geoscope.
