RENDERINGS
AS BUILT/CONSTRUCTION
DETAILS
KPM were engaged directly by Taraf to provide Structural engineering services. For these 2 residential towers in Jumeirah Village Circle in Dubai. Towers A and B are 20 and 34 floors respectively.
■ The efficient use of the core with the designed framing system resulted in optimised wall thicknesses catering to the architectural and ID design intent.
■ The floor plates are designed as post tensioned flat slabs. This approach allowed for smaller column sizes. The beam-free structural system also helped achieve and enhance the building elevation design.
■ A piled raft foundation for the towers was adopted and an isolated / combined footing system was utilised to minimise the project cost.
CHALLENGES
The Climate in Kazakhstan differs drastically. In summer the temperatures average more than 30 °C and in winter average −20 °C. Due to such varying temperature Heating Ventilation and Air Conditioning within all the areas were to be designed precisely. The air volume for basements were humongous, which resulted in high level of MEP service coordination to achieve the required clear height. The location of diesel generator was within the building boundary and at basement-1 making it difficult for ventilation and DG exhaust.
SOLUTIONS
To incorporate the HVAC challenges, heating plants were introduced at MEP level of 5 towers. All the ducting catering to spaces were within the towers were designed with VAV boxes with heaters. For basement ventilation the coil sizes were big, resulting in coordination issues at driveway. Coil rooms were introduced and multiple outlet were taken. The location of diesel generator was shifted to incorporate local body requirements and the exhausts were coordinated to a location of individual DG shaft.
