DETAILS
The Celestia Development is a 109,000sqm Hotel Serviced Apartments by Damac. The project is located in Dubai World Central and is part of the Dubai Expo 2020 overall master plan. The structure comprises 2B+G+7 floors. The basement sub structure is temporarily supported using anchored contiguous piles where required and the permanent sub structure is a traditional reinforced concrete retaining walls and slabs up to and including the ground floor slab. The super structure is currently designed as post tensioned in situ concrete flat slabs on columns. The Structural system provides an uninterrupted free ceiling space for MEP services and a very efficient floor to floor height is also achieved.
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.
