Ramboll has just topped out the supertall tower, Damac Heights in the Dubai Marina. Pushing 340m it is set to become one of the world’s top 100 tallest buildings once complete in 2017.
Damac Heights is an iconic residential tower located in the Dubai Marina. The vision of the architect was to produce a super high rise building with sleek curves as the tower rises from its Marina side plot. Cantilevering balconies in the apartments overlook the Palm Jumeirah.
Integrated Structure and Services Design
The superstructure is constructed from reinforced concrete cores and columns and post tensioned concrete slabs. The elegant curving form of the building is created from inclining the columns to follow the line of the tower façade. The tapering roof top of the building is formed from a light weight steel frame.
Ramboll’s multi-disciplinary team worked closely with the architect to optimise the cores and shafts to minimise elevator waiting times, provide adequate space for services distribution and optimal structural capacity to cater for the vertical and lateral loads imposed on the tower. The supertall tower will be subjected to high wind loads during its life. Ramboll’s engineers collaborated with world leading wind tunnel testing specialists to determine the wind loads on the building.
This understanding of the complex wind loading enabled an extremely efficient design of both the main stability core and shear wall elements. It also provided a highly economic and safe design of the façade support system.
Ramboll’s solution maximised the lettable floor area for the client and realised the vision of a truly stunning building.
To maximise the sellable area it was necessary to provide all the parking below ground and this resulted in 5 levels of basements being constructed immediately adjacent to the Marina wall.
This required the Ramboll team to combine the skills of our geotechnical and structures teams to minimise water ingress to the site as the 20m excavation was dug. A series of anchors and props provided stability to the deep secant pile walls whilst maintaining clear space away from critical path construction.
