Case Studies
Jumeirah Beach Residence District Cooling Plant, Dubai
The Jumeirah Beach Residence (JBR) comprises of 36 luxury residential apartment towers and 4 hotel towers. The Project will cater to a community of over 25,000 residents with its 22 million square foot gross floor area developed across a length of 1.7 kilometers (1 mile). JBR will be a self-contained community with amenities like restaurants, cineplexes, health clubs, sport centers, medical facilities, beach clubs, children's play areas, housekeeping, retail stores, supermarkets, nursery schools, and will be home to more than 400 stores and restaurants.
District Cooling System (DCS) is a considerably more cost-efficient alternative to air-cooled chiller systems. It is estimated that chiller plants account for up to 60 per cent of electricity usage in large buildings. With DCS, building owners can reduce electricity usage substantially. Additionally there are cost savings and other benefits from reduced maintenance, enhanced efficiency and reliability, space savings, flexibility of air-conditioning load and a plant life that is twice that of traditional plants. With a total capacity of 60,000 tons, the JBR (DCS) plant is the single-largest district cooling plant in the region.
Drake & Scull was awarded the complete project and succeeded in bringing the plant on-line within the stipulated schedule and without any delays to third parties. The project team was able to achieve these results with the close cooperation of the client, Dubai Properties; project managers Mace International and building services consultants, Hyder Consulting Middle East.
The chilled water system of the Jumeirah Beach Residence has a maximum capacity of 60,000 tons of refrigeration (17,060 KW) at 55,000 TR duty and 5,000 TR standby, designed to accommodate the cooling requirement of the built up area of approximately 22 million square foot.
The design life of the plant and all equipment is twenty five years and the overall efficiency of the plant is designed to meet a power consumption efficiency of 0.93 KW/TR.
The focal point of the district cooling plant is the skid mounted packaged chiller modules. This water chiller module is housed in a container-type package which consists of 2 nos. centrifugal water chillers arranged in series with a capacity of 2666 tons for the upstream chiller and 2334 tons for the downstream unit, totaling 5000 tons. Also included in the package are the primary chilled water pump, primary circuit expansion vessel, condenser water pump, the pumps’ electrical switchgear, the Motor Control Center of the VFD-controlled Cooling Tower, complete with all associated system pipe work, cables, wireways, module cooling equipment, instrumentation and control system interfaced with the PLC-based chiller controller. The design chilled water temperatures for the secondary side of the system are 4°C leaving (flow) and 14°C entering (return) the plant.
There are twelve chiller modules positioned in parallel. The total capacity of which is 60,000 tons. The 5,000 tons of the total capacity equivalent to one chiller module serves as a stand-by unit to be used in case any of the chiller modules breaks down or it is off-line for maintenance.
The Secondary Chilled Water Reticulation System and Energy Transfer System cover the secondary chilled water reticulation piping circuit from the outlet of the Central Cooling Plant to the Energy Transfer Stations at the building loads. The secondary chilled water reticulation system encircles the JBR building load site from the Central Cooling Plant to form a ring main.
The route that the ring main follow from the Central Cooling Plant as buried pipe and traverse the marina seabed via a buried water-proof concrete structure culvert designed specifically to carry the ring main and high voltage electrical supplied to the JBR building loads.

The facilities spread over the 20,000m2 of a two-storey building, include six operation theatres, three resuscitation departments, CT scanning facilities, an intensive care unit and two radiology departments.
Drake & Scull won the role as MEP contractor for the project, which involved the supply, installation, testing, commissioning and operation of the MEP systems. In terms of the demands on the MEP installation, hospital projects are among the most complex. The amount and the combination of services that are required are generally larger than in other buildings and consideration of the end-user plays a critical role. The products used in the project had to be carefully specified, with many specialist items needed, as hygiene is a top priority for the client. This scale and the need to maintain high levels of hygiene meant very close day-to-day co-ordination with the main and civil contractors was essential. All products installed were considered, from the largest plant down to manhole covers.
The creation of the Middle East's first dedicated accident, emergency and trauma centre needed a high level of attention from the MEP contractor, with specialist equipment and installation techniques required. Drake & Scull’s intensive experience and knowledge about the specifics of hospital projects systems meant that the firm’s work was eased as lessons learned from previous similar projects were applied at the Rashid Centre from the beginning of the project.

The Jewels twin towers, located at the Dubai Marina Waterfront, rise to an imposing 20 storey, and will house 120 units and 5 villas. These include one, two, three bedroom apartments, duplexes, penthouses, lofts, retail shops and luxurious villas overlooking the spectacular marina. Complementing this wide array of residences is an amazing range of amenities - high-end finishes, full home automation, fully fitted kitchens and bathrooms, even a Jacuzzi in the master's bathroom.
The jewels Twin Towers proved to be one of Drake & Scull’s prestegious projects and remarkable triumph, as the project team faced a few difficulties during the execution of the project due to the towers’ unique curved design which is refelected on the interior of the building as well. The irregularity in the shape meant that none of the floors shared the same size and design. This variety presented a challenge in itself due to the different layout of each flat. In addition, each duplex, villa, and penthouse has a private swimming pool and an outdoor jacuzzi in the penthouses only.
Through team work and close cooperation between all parties involved in this project including the Client himself, Consultant, Project Manager, and the Contractor Drake & Scull was able to complete all the jobs successfully and deliver the project on time.
