en.Wedoany.com Reported - Recently, the main steel structure of the Habtoor super high-rise project, located in the Business Bay of downtown Dubai, UAE, has been topped out. The skyscraper is 355.9 meters high, with 90 floors, a total construction area of 365,400 square meters, and uses over 40,000 tons of steel. CSCEC Steel Structure was responsible for the detailed design, manufacturing, and installation of the steel structure, while China Railway 18th Bureau Group served as the main contractor.
Designed by MAK Consultancy & Architects, the skyscraper features a full glass curtain wall system, characterized by large-wave, double-curved, hidden-frame units on the north and south facades, with curves gradually rising from the L8 level. The building has 4 core tubes and 10 shear walls, with a standard single-floor area exceeding 4,200 square meters, making its overall scale three times that of a conventional super high-rise project.
The CSCEC Steel Structure team fully utilized BIM technology for 3D visualization rehearsals, resolving interdisciplinary conflicts in advance, which increased structural construction efficiency by 17% and achieved standard floor construction speed. The total steel structure weight of a single truss layer in this skyscraper exceeds 3,500 tons, with the largest component weighing 15 tons, extensively using 120mm thick S460 high-strength steel. The project department adopted digital simulation pre-assembly technology, strictly controlling pre-welding assembly deviation within 4 millimeters, established a specialized welding team, trained 60 Chinese and foreign welders in advance, and ensured quality through high-precision measurement and ultrasonic non-destructive testing. The second key truss layer was completed in 45 days and passed the Dubai Municipality acceptance in one go.
With a total investment of approximately 1 billion US dollars, the skyscraper will become the world's largest single apartment building upon completion.
