Dubai burj al-arab hotel2 copy

  1. 1. Dubai Burj-al-arab Hotel By: Lim Tze Hsing 1007P79406 Ong Chian Yee 0314519 Lim Yee Leng 0307767 Sim Wen Yi 0308610
  2. 2. Background of Burj al arab hotel Meaning : Arabian Tower. Location : sandy beach of Jumeirah, Dubai. • Built 280m offshore of private island Designed by Architect Tom Wright
  3. 3. Construction background Construction began in 1994 and completed on site in 1999. Foundation built on sea.( took 3 years to complete and 5 years construction period.) 321 meters high above the sea level.
  4. 4. Design background Designed to create an icon for Dubai, which represents urban revolution and to mimic the shape of Arab Dhow, a type of Arabian Vessel. Shape of modern yacht sail to reflect Dubai’s nautical heritage combined with a modern aspect moving towards the future as a global tourists destination.
  5. 5. The types of structure • High-rise • atrium • cantilever • landing pad • truss
  6. 6. V shape concrete tower • reinforced concrete tower • used steel bracing (Inner Reinforced Concrete V) for supporting. • The front (shore-facing) facade is the constructed of two tiers of huge, steel ‘X’ trusses.
  7. 7. Steel exoskeleton • Two main structure of the exoskeleton is the diagonal truss and ‘Yacht’ structure • The assembled segment were lifted and erected in position using the tower cranes from ground floor to top. • Together the reinforced concrete and the exoskeleton act as a composite and provide the structure horizontal stability in all directions
  8. 8. Steel exoskeleton (cont’d) • The diagonal trusses on the side of the building are as long as a football pitch and weigh as much as 20 double-decker busses. They were built 15 KM from the site and brought by road to Dubai on huge 80 wheel lorries which had to be specially imported from South Africa. The highest truss took a day to lift into place. • If one man was to build the building himself it would take about 8,000 years to finish.
  9. 9. Atrium • The tallest atrium lobby in the world at 180meters (590ft) • It dominates the interior of the hotel, and takes up over one-third of the interior space. • The screen that encloses the third side of the atrium is made of 1mm thick glass fiber fabric with a Teflon coat to stop the dirt sticking.
  10. 10. Atrium (cont’d) • The screen is the largest of its type and covers an area of one and a half football pitch and it is hung from the top of the building by over a kilometer of 52mm cable.
  11. 11. The material • carbon fiber • reinforced concrete • glass fiber • Gold • Steel • Aluminium • Marble
  12. 12. The Material(cont’d) • The architectural materials of the hotel consist of only a few mediums. Outside the exterior facade consists of 50,000m2 of glazed curtain wall of 35,000m2 aluminum cladding designed by Al Abbar Group. • Glass and steel make up the remaining portions of the exterior. The Steel structure was clad with 6mm composite aluminum panels.
  13. 13. The Material(cont’d) • The design is able to with stand a wind load of 9kPa and was designed to drain water at each horizontal joint. • Inside the hotel the materials get even more expensive than the outside. The interior features marble and 24 carat gold leaf. • Like the exterior, the interior steel structure is also clad with 6 mm composite aluminum.
  14. 14. Industrialized building systems (IBS) implemented during the construction •IBS- the building components(wall, floor slab, beam, column, staircase) are mass produced either in factory/ at site under strict quality control and minimal on site activities. •In order to reduce labors , improve construction's productivity, reduce wasteful construction method, increase site safety, environmental friendly, cost saving, speed up construction time. •Recognized as the world’s only 7 star Burj-al-arab is not just a world-class luxury hotel, but also one of the most successful project in Dubai which had implemented IBS during the construction of the building. •Main core area- using Cantilever’s Top Climbing Jump Form system. Cantilever Pty Ltd designed and supplied 300 ton for the forming system. •Wing walls & stair cores- using Doka’s SKE automatic-climbing form system. Doka designed the forms such that only two climbing brackets per form are required.
  15. 15. • Main floors-designed by Cantilever Pty Ltd.Designed as a flying cable and supported by brackets attached to the walls.The frame for the form was built with castellated steel beams and measured 18.3m long by 8.1m wide. 18.3m x 8.1m. • Meinhardt international done the joint venture re-engineer the slabs to a post tensioned design, it reduces the labors on reinforcing steel and also time required to get enough strength to strip the form.
  16. 16. How IBS helped in construction
  17. 17. Can be classified into 5 main groups: Pre-cast Concrete Framing, Panel and Box Systems ~ most common IBS elements ~ e.g. precast concrete columns, beams, slabs, walls, „3D‟ components, lightweight precast concrete and etc. Steel Formwork Systems ~ considered as the “least prefabricated” IBS. ~ e.g. tunnel forms, tilt-up systems, permanent steel formwork (metal decks) and etc.
  18. 18. Steel Framing Systems ~ commonly used with pre-cast concrete. ~ always been the popular choice in construction of skyscrapers. ~ e.g. steel beams and columns, portal frames, roof trusses and etc. Prefabricated Timber Framing Systems ~ have their own niche market. ~ normally used in simple houses. ~ e.g. timber frames and roof trusses and etc.
  19. 19. Block Work Systems ~ have been revolutionized to achieve more effective works. ~ e.g. interlocking concrete masonry units (CMU) and lightweight concrete blocks
  20. 20. Benefits of IBS:  to achieve higher quality products with minimum wastages.  helps to reduce the usage of timber formwork and props.  a safer and clean construction site.  faster the completion of the construction.  minimize labour usage/ un-skilled workers.  reduce overall construction budget.
