54-storey Tower located in the Dubai International Finance Centre
Eversendai Engineering L.L.C, UAE was awarded 24,000 metric tons of structural steel works of ICD Brookfield Place Project in Dubai, UAE.
The scope of Eversendai was to provide connection design, shop drawings, BIM coordination, erection engineering study & stage analysis, workshop fabrication drawings, supply, fabrication, painting, fire proofing, composite floor decking, and erection of structural steel works. All the above scope of work was completely taken care of by the in-house Design & Engineering Department of Eversendai and was successfully completed in line with project schedules.
The project clients are Brookfield Properties & Investment Corporation of Dubai. The project managers are AECOM. The architectural design by Foster + Partners. Structural design by Robert Bird Group. Architect of Record is Brewer Smith & Brewer Gulf - Dubai. The main contractor is Brookfield Multiplex & Ssangyong Engineering & Construction JV - Dubai.
The ICD Brookfield Place is a 54-storey tower about 282m high, located in the Dubai International Finance Centre (DIFC), Dubai.
The project consists of a 54-storey Tower containing over 83,600 m² of office space, 7-level below ground basement capable of accommodating 2,700 vehicles, adjacent podium level structures containing a five-storey 14,000 m² retail center and a 1,670 m² triangular shaped five-storey high open atrium roof structure called the Summer Garden.
The top three floors of the tower are built as ‘Sky View suites’ with internal gardens, featuring 6-meter ceilings. These floors are hung from outrigger steel framing.
The project has been designed to achieve LEED Gold certification.
The structural steel of Eversenadi Scope on this project is about 24,100 metric tons of primary steel and about 650 metric tons of temporary steel for the erection of primary steel.
The steel consists of 5-storey high A-frames on four sides supporting concrete filled steel tube (CFT) columns above. The floor plates are deck slabs with steel beams spanning between the central RC core wall and the perimeter CFT columns.
The primary steel structure consists of an A-Frame (3245 metric tons). Typical tower floors include CFT columns, floor beams, cast-in spandrel beams, roof floors & outrigger (16,785 metric tons), South Podium (1495 metric tons), North Podium roof & scenic lift (730 metric tons) & Podium Summer Garden (1845 metric tons).
Each of the A-frames consist of five nodes, two at the base, two in the middle and one at the apex. Each node weighs about 70-80 metric tons, and installed using the world’s largest luffing crane. The legs of the A-frame are a diamond-shaped steel box with concrete infill.
What benefits did utilizing BIM and Tekla software bring to the project?
Considering the complex geometric nature and precise setout requirements at various stages of construction, the Tekla steel structures modeling played a vital role in the successful completion of this project. Tekla BIMsight was used extensively to identify the clashes with other trades like Roofing Contractor, Façade Contractor, MEP Contractor and RCC Contractor. These clashes were resolved during the design stage itself.
The unique and complex steel erection coordination requirements made this project one of the most challenging projects ever for Eversendai. As always with Eversendai, this project was also successfully modeled & coordinated with all other trades, fabrication drawings were released, fabricated and erected in line with the project schedule.
