World’s largest shopping mall in Dubai

World’s largest shopping mall to open in Dubai


The world’s largest shopping mall, the Dubai Mall, is due to open in Dubai at the end of August 2008. Set to be Emaar Malls Group’s flagship shopping mall development, Dubai Mall will be located at the centrepiece of the region’s most prestigious urban development to date, Downtown Burj Dubai, soon to be home to the world’s tallest building.

The Dubai Mall will add to the emirate’s impressive portfolio of shopping excellence, resulting in an unprecedented surge in Dubai’s retail sector, which is the fastest growing industry in the Middle East. According to industry forecasts, it has recently been announced that the retail sector is projected to exceed £250 billion in the Middle East by the year 2010, with Dubai leading the way in the region.

Dubai accounts for more than 50 per cent of the UAE’s shopping footfall and has long been famed for its world-class malls and the range of shops on offer. With everything from high-street stores such as Boots, Debenhams, and H&M to a range of designer boutiques including a branch of Harvey Nichols, shopping in Dubai has something to offer everyone. And now with the opening of the Dubai Mall, visitors can expect even more from the emirate.

The size of 50 football pitches, Dubai Mall is expected to attract well over 30 million visitors in its first year alone. The project will be a lifestyle and entertainment destination that will introduce pioneering and innovative leisure and entertainment concepts, set to revolutionise the modern shopping experience.

Amongst some of the ground-breaking attractions that the Dubai Mall will offer are 1,200 stores and 120 food and beverage outlets. It will also boast magnificent water features and one of the world’s largest indoor aquariums, the world’s largest indoor gold souk, an Olympic-size ice rink, and the region’s first SEGA indoor theme park.

In addition to the Dubai Mall, there are well over 50 other shopping malls with a variety of retail outlets including Souk Al Bahar an entertainment destination with over 130 shops. Dubai Outlet Mall, which launched at the end of 2007, and promotes value-shopping by retailing big brands such as Calvin Klein and Guess at fantastic discounts. And Wafi Mall one of the first shopping malls in the emirate and part of the Egyptian themed Wafi City, which boasts Cleopatra's Spa, Pharaoh's Club including a climbing wall and lazy river, and Khan Murjan - a subterranean artisan's market. More information on Dubai’s shopping malls and facilities can be found at dubaicityguide.com/shop.

Dubai Duty Free at Dubai International Airport is about ten minutes from the city centre and ranks among one of the largest duty-free operations in the world. Furthermore, the emirate has created a range of events to celebrate its shopping excellence. Dubai Summer Surprises, which runs in the summer months, and Dubai Shopping Festival which is the largest retailing event in the Middle East and runs in the winter, are host to a variety of activities.

Shopping malls are converted into venues for live entertainment, music, dancing, competitions, workshops and interactive programmes. These events are organised and promoted by a unique partnership between the Government of Dubai and the city’s enterprising corporate sector, acting as a catalyst in the development of Dubai’s growing retail sector and establishing the emirate’s place on the regional and international map.

For a more authentic experience, Dubai’s traditional Arabian souks showcase the emirate’s finest local products, from gold, spices and textiles through to fruit and fish. Remnant of the 19th century, the majority of souks are located in the Deira and Bur Dubai districts and are great places to haggle for a bargain.

Ian Scott, UK and Ireland director of the Government of Dubai Department of Tourism and Commerce Marketing comments: “Dubai has seen an incredible boom in its retail sector with many exciting and pioneering shopping developments being created to inspire visitors. Dubai’s world-class shopping malls and trailblazing projects such as the Dubai Mall showcase how people have come to expect the best from the emirate. And, with all prices tax-free Dubai is well and truly setting itself apart from other holiday hotspots.

“Combined with the ever expanding and exciting new retail developments, such as the world’s first fashion island Isla Moda, new malls such as the Mall of Arabia which will be part of the City of Arabia in the Dubailand theme park, and Dubai Festival City which will comprise over 600 shops including 25 flagship stores, the emirate continues to fuel the ever-increasing demand, with its phenomenal growth on track to welcoming 15 million visitors by 2015.”

Burj Dubai May 26th 2008 photo update

Burj Dubai May 26th 2008 photo update, here is two photos of the Burj Dubai they show the wonderful progress of the cladding. I hope to have some photos of the 10th level of steel.. A good close up that shows a steel beam over 650 meters. So...... stay tuned I should have one in a day or two.

Servicing the Burj Dubai

With services risers running the full 600m+ height of the building, designing MEP systems to serve the Burj Dubai has taken great care. How will the tower be serviced? Billed as the tallest building in the world, the task of providing MEP services to the Burj Dubai was always going to be a challenge. The world records made by the Emaar Properties' project stretch to the services themselves, with the longest lift shaft in the world and mechanical operating pressures that would send some MEP consultants into a cold sweat.

Despite this, the mission of providing reliable and efficient MEP services for the tower has involved the use of proven technologies and off-the-shelf products - albeit under a very close and detailed design and installation process and a major logistics programme.

Design considerations

The original design of the MEP services systems was carried out by the Chicago office of international consultant Skidmore, Owings and Merrill (SOM). "They were the original architect, structural engineer and MEP engineer," explains Hyder Consulting Middle East senior mechanical engineer Alastair Mitchell. As supervision consultant for the project Hyder Consulting is jointly responsible for ensuring the correct installation of the MEP services to this design. "As part of or contract with Emaar we have adopted [SOM's] design - this makes us jointly responsible for the design with SOM," adds Mitchell.

With all eyes of the world on the project, ensuring a 100% reliable system in all circumstances is of primary importance. With this in mind, one of the major decisions that was taken at the design stage was to use tried-and-tested products and systems wherever possible. Rather than opt for radical, new technologies a base of solid electrical and mechanical design has been used for the systems, with input from the process and oil and gas industry standards and best practice referred to when the pressures and system sizes grew beyond those of a standard building services project.

"[The MEP system] is quite standard in it's design in that they haven't done anything radically different," confirms Mitchell. The hydraulics of this building are where we differ [from a smaller building] because of the extreme height of the building; what SOM has rightly done is taken established practices but extended them a bit - we've had to push the boundaries.

They've taken established principals and refined them for the ultra high-rise sector," he adds. This has resulted in the use of higher specification materials and products such as pumps than may normally be used in a commercial high-rise structure. It has also meant the need for detailed stress analysis at the pipework expansion and contraction points because of the extreme nature and size of the MEP services being installed. We're operating at higher pressures than you would normally see in the construction industry generally," explains Mitchell.

It's quite easy to specify - you specify by the design pressure - but when it comes to actually selecting the equipment there's a lot of responsibility involved in making sure that we get the right products for the application," he stresses. All equipment used in the MEP systems has also passed anti-seismic and anti-vibration specifications that take into account the natural movement and deflection of the building. The building is split into five zones, with the main mechanical and electrical plantrooms located at approximately 30-floor intervals. These typically feed the 15 floors above and 15 floors below.

The primary distribution route for services is through main risers within the central core of the structure, which remains the same size to level 150 despite the overall building shape tapering with height. The smaller floor footprints at the higher levels mean that lower capacities of plant such as pumps, air handling units and heat exchangers are needed. A central building management system (bms) will oversee the MEP system operations throughout the tower. Local control panels will be mounted in each plantroom and the podium, these outstations will communicate with each other and the central bms control rooms over a main fibre optic backbone cabling system.

All MEP systems will be connected to the bms, which is used to control and monitor all the services distributed around the building. The bms will interface with other systems such as fire alarms, security and the hotel management system to provide a fully integrated control and monitoring system for the entire project.

Installation of services

With the tower central to a very tight site within an inner-city location, a major logistics plan was needed to ensure build schedules could be maintained and materials and labour delivered to the correct place when needed. Most deliveries have been made during the night and storage space has been made available to the MEP contractors within the podium and basement areas of the tower so bulk supplies of materials could be ordered.

"Great thought was given regarding the material and labour movement inside the building," assures Greg Sang, director - projects, Emaar. "For example, all materials are shifted to the job place during the night time and each contractor is given specific timings for shifting materials and labour," he adds.
