It is one of the most fascinating,complex and challenging project everundertaken by Eversendai.The structure is a standing example forthe quote “Architect’s Dream, Engineer’sNight Mare”.Steel is the best-opted material for thisbuilding due to its flexibility andconstructability.The Burj Al Arab building is made of 28storeys of split levels (56 storey) with100,000 m2 floor area, 60000 m3 ofconcrete, 9,000 ton of reinforcing steel,12,000 ton of structural steelworks,80000 m2 of cladding, 10000 m2 of teflon- coated fiber glass cloth and sits on 250piles of 1.5m in size, 45m under the sea,the piles rely on friction as there is onlypiles embedded in sand to hold thebuilding up.Construction of the Burj Al Arab hotelbegan in1994, and its doors wereopened to guests in December,1999.The top is the mast and below it is thehelipad, and extending from the otherside of the hotel, over the ocean, is arestaurant supported by a cantileverstructure. A remarkable element of itsarchitecture is the outer beachwardsteel wall of the atrium, which is coveredwith a woven, Teflon-coated fiber glasscloth. The Burj al-Arab features thetallest atrium lobby in the worldstanding at 180m.This Burj Al Arab building is a hybrid Vshape structure constructed in concreteup to 209 m and blended with structuralsteel creating an impressiveengineering master piece. This Vshapedframe wraps around the Vreinforced concrete tower containingthe hotel rooms and lobbies. The two
structures connect along a shored,
reinforced concrete spine at the base of
the V, and at two points along the
curving atrium wall.
Ninety percent of the steel structures
constructed were outside the building
and was potentially dangerous to erect.
Three self-climbing tower cranes with a
maximum lift capacity of 64 tons at 8.0
meters radius were used. Some of the
embedment weighed as high as 60
tons.
About 100 tons of electrodes were
burned and the welding defect ratio
was less then 1%.
The Burj Al Arab does not have ordinary
rooms; rather it is divided into 202
duplex suites with split levels. The
smallest suite occupies an area of 169 sq
m, and the largest one covers 780 sq m.
It is one of the most expensive hotels in
the world to stay in. The cost of staying
in a suite begins at US$1,000 per night
and increases to over US$15,000 per
night; the Royal Suite is the most
expensive, at US$28,000 per night.
We are proud to say that this project
was the major break through for
Eversendai Engineering in Middle East
region. The Project was been awarded
to Eversendai purely based on its
construction methodology, capability
and reliability. Eversendai scope
includes the site assembly, alignment,
welding and erection of structural steel
works.
Total Steel works are phased into
Exoskeleton Rear leg, Horizontals,
Diagonals, Rear Brace Frame, Helipad,
Sky Restaurant, Atrium and the Mast :-
Exoskeleton Rear leg Erection
The exoskeleton is made up of two legs
on both sides of the building starting
from the ground level to 273 meters
and connected to the front legs starting
from 208m. The total weight of the
structure is about 2,800 tons. The
structure was made of two build up H
sections of 1.8 metre wide by 4.5 metre
deep plate girders (inner and outer legs)
connected by a lattice braced members
and segmented to 40 ton capacity 12m
in length to create the gentle curve in
concurrence with the building edge
developing the shape of a sail.
The assembled segment were lifted and
erected in position using the tower
cranes from ground floor to top, one
over another using specially designed
lifting lugs with 20 ton chain hoists in
the pre-determined lifting location to
lift the segment in required angle.
After each segment were erected,
temporary struts were introduced to tie
Hybrid V shape structure back the rear leg to the core wall to
