In the middle of the Sharjah Desert in the United Arab Emirates, a futuristic building is currently being constructed according to the plans of Zaha Hadid. As inspiration, the famous architect used nothing more than sand dunes. PERI is supporting this ambitious project with an individually-designed planning solution, project-specific formwork elements as well as by providing comprehensive support through its local team of experts.
After completion, around 7,000 m² of usable space will serve as the headquarters of the award-winning Bee'ah company which has made a name for itself in the environmental and waste management sector. The complex complies with state-of-the-art technology in all aspects. The shape of the structure mimics dunes crossing each other thus provide a permanent reference to the surrounding natural environment. The dome shape of the roof offers a number of advantages: in addition to the exceptional spatial perception, the architecture impresses with its reduced energy and resource consumption. Furthermore, the entrance hall is also optimally supplied with natural daylight. Last but not least, the area of glass surface subjected to direct exposure to the desert sun is reduced. As a result, the shape of the building provides optimum protection against the shamal wind that occurs several times a year in the region.
Design brought to fruition
The dome above the entrance hall is 23 m long and 17 m wide, and plays a central role in the design concept of the project. Through the use of proven formwork and scaffolding systems, the PERI team created a very efficient solution for constructing this huge vaulted section. As shoring for the slab formwork, the modular PERI UP Flex Scaffolding System provides a cost-effective solution. The continuous 25 cm or 50 cm system grid as well as the possibility of combining with SRU Steel Walers taken from the VARIOKIT Engineering Construction Kit, allows the load-bearing construction to be optimally adapted to different geometries and loads. In the center of the dome, the steadily increasing height of the shoring reaches its maximum height of 15.30 m.
The entire dome is realized in four formwork sections. The demands placed on the architectural concrete quality are very high and the tolerance in terms of joint pattern, anchor points and screw heads remained extremely low. PERI engineers therefore precisely adapted the formwork solution to accommodate these planning specifications: Both the positioning of the anchors as well as the formation of the formwork joints were defined in great detail. For the load-bearing substructure of the individual segments, primarily VARIO GT 24 System Components, SLS Heavy-Duty Spindles and SRU Steel Walers are used. Realization of the high-quality plywood formers and panels was achieved using a customized production process in each case and correspondingly adapted to match the arched slab dimensions. In addition, the tailor-made formwork solution takes into account all required recesses.
Thanks to the well-coordinated cooperation between the entire planning and assembly teams along with the jobsite crew, an excellent architectural concrete result has been achieved in the course of the execution of the work that fully complies with the strict architectural requirements.
