1.Introduction
Just five years in the making, The Palm Jumeirah is a stunning feat of design,
engineering and creativity. Located between The Palm Jebel Ali and The World; two other
spectacular landmarks in the lines of Palm Jumeirah, it is an icon of Dubai and the world’s
newest landmark. The project is being developed by the Nakheel Corporation, which is
held by the government of Dubai. The Palm Jumeirah measures 5km², has created 560ha
of land and has added 78.6km to the country's 72km coastline.
The Prime Minister and Ruler of Dubai HH Sheikh Mohammed bin Rashid Al Maktoum,
envisioned the creation of such islands because of the business and tourism potential of
such waterfront areas. It was the realization that the country cannot depend on its oil
reserves forever to drive its economy. World over it is seen that waterfront properties
command premium price. The Palm was conceived as a natural progression in a
succession of extraordinary tourism initiatives in Dubai.
Construction in-progress
It was also an answer to a practical challenge, which was how to create more beachfront
when the emirate possessed only 72km of coastline. So, was born the ingenious idea of
building artificial waterfronts that are accessible to the coast by roads and boats.
The essence of the project is its design – its palm shape, which dictated every step of its
development. The choice was both personal and professional. It symbolizes Dubai's
heritage (the palm is known as the 'bride of the orchard' in Dubai) as well as putting

water, the most important source of sustenance, shelter and trade, centre stage. Its
shape also provides the perfect geometry to create the longest stretch of new beachfront.
With these simple decisions made, the next step was to commission a vast wealth of
expertise from a host of disciplines in order to reclaim the land and turn it into a safe and
habitable environment
The project took four years of methodical planning and exhaustive feasibility studies in
Dubai, ensuring that the islands would not disrupt the environment. The first stage of the
development of The Palm Islands includes the construction of the land foundations, which
involves sand transfer and rock placement. Following this, the next stage will involve the
building of infrastructure and services, as well as the 300 meter (990 feet) bridges linking
the islands to the mainland. The final stage consists of the construction of homes,
townhouses, and apartments. At the peak of construction, 40,000 employees were
working on the project each day, turning 94 million cubic meters of sand and seven
million tonnes of rock into a leisure and lifestyle resort fit for the 21st century and beyond.
When fully completed, it will become home to 32 five-star hotels with 25,000 guests,
20,000 day visitors and about 60,000 residents in apartments and villas. Its population will
have five beach resorts, four marinas, a monorail and vast expanse of retail and
commercial units at their disposal. Comprised of a two-kilometer long trunk. A crown
made of 17 fronds, and a surrounding crescent, the island boasts more than 4000 luxury
villas and apartments, over 30 of the world’s top hotels including The TAJ and over 75
kilometers of pristine beaches.

3. Construction of the island
2.1 Dredging
Dredger pumps sand to form a palm-shaped island
Construction on the palm islands began in 2001. Divers surveyed the seabed and
worke-rs constructed a crescent-shaped breakwater from blasted mountain rock. The
Crescent of Palm Jumeirah stands a little more than 13 feet above low tide sea level and
sits in 34 feet of water at its deepest point. Sand, covered by an erosion-preventing
water-permeable geo-textile, makes up the breakwater's lowest layer. One-ton rocks
cover the sand, and two layers of large rocks weighing up to six tons each cap the
structure. A "toe" placed by a floating crane sits inside the Crescent. The breakwater also
has two 328-foot openings on each side to eliminate stagnation in the 16 narrow, deep
channels. These gaps allow water to completely circulate every 13 days.
Although five workers were swept away- by a wave and one drowned, the designers at
Nakheel believe the breakwater will protect the palm island from average gulf weather
and even an enormous storm. They even suggest that villas barely 10 feet above sea
level will be safe from the rising seas of global warming. The palm islands themselves are
constructed from sand dredged from the sea floor. Palm Jumeirah is made from
3,257,212,970.389 cubic feet of ocean sand vibro-compacted into place. Vibrocompaction increases the density of loose sand by saturating it with jets of water and
vibrating it with probes.

(72 Km Long)
The Jan De Nul Group started working on the Palm Jebel Ali in 2002 and had finished by
the end of 2006. The reclamation project for the Palm Jebel Ali includes the creation of a
four-kilometre-long peninsula, protected by a 200-metre-wide, seventeen-kilometre long
circular breakwater. 210,000,000 m3 of rock, sand and limestone were reclaimed (partly
originating from the Jebel Ali Entrance Channel dredging works). There are approximately
10,000,000 cubic metres of rocks in the slope protection works.

4. Monorail
Train on the monorail
On 30th April 2009, the Palm Jumeirah Transit System started operation of their monorail
system. This monorail is the first railway system in UAE and also the first monorail system
in Middle East. The Palm Jumeirah Island is an artificial island constructed by NAKHEEL,
UAE’s largest property developer, and one of the main projects in Dubai for their resort
development. The island is shaped as palm trees and you can see a luxury hotel, a
recreational facility and a lot of resort villas there. Hitachi monorail in Palm Jumeirah
Island connects mainland Dubai and the Palm Jumeirah Island. This monorail has 4
stations, Gateway Tower,
Trump Tower, Palm
Mall
and
Atlantis
Aquaventure
and
the
line
length
is
approximately
5.4km.
Hitachi
was
awarded
the
contract in December
2006
to
supply
monorail system including
rolling stock (4 trains
of 3-car configuration),
track
switch,
signaling
system,
communication
system and substation
etc. The streamlined
shape of the vehicles
matches
the
atmosphere of the resort
island and they were
also designed to suit the
unique climate in
Middle East, such as
extreme
temperature
and
sandblast.
The
operation system of this
monorail is ATO
(Automatic
Train
Operation),
driverless with attendants
for any emergency
situations. This monorail
runs at an average
speed of 35km/h and the
maximum speed of
70km/h and can carry up
to 2,400pphpd when
3 trains are operated. In this world’s largest artificial resort island, the monorail is an
effective and ideal means of transportation with the smart structure and low impact on the
surrounding environment or scenery.

5. Tunnel
The outer ring with its hotel facilities and a gigantic water park is connected to the trunk
by a 996 m long tunnel. Including the entry and exit ramps, the tunnel construction has an
overall length of 1.4 km of which around 600 m runs underwater up to depths of 25 m.
The triple-tubed rectangular cross-section with three lanes in each individual tunnel along
with a central supply tunnel were
constructed using the cut-andcover
method. Just pumping out the excavation
pit took one month. The cross-section is
38.00 m wide and 9.16 m high, the
reinforced concrete bottom plate has a
thickness ranging from 1.54 m to 2.08 m
whilst the slab thickness varied between
1.50 m and 2.00 m. The outer walls are
1.50 m thick. Forming, reinforement work
and concreting were carried out using the
separate casting method. In 25 m long
concreting
steps
and
four
cycle
sequences, the tunnel bottom plate, two
wall sections respectively and then the
slab could be concreted one after the
other. PERI system components from the
VARIO girder wall formwork system
provided the ideal basis for all areas. Then
the load-bearing GT 24 formwork girders
as well as SRZ steel walers could be used
very fl exibly as slab formwork as well. The
concrete loads during onstruction of the
tunnel slab were safely transferred into the bottom plate via PD 8 shoring towers.

6. District Cooling System
District heating is a system for distributing heat generated in a centralized location for
residential and commercial heating requirements such as space heating and water
heating. The heat is often obtained from a cogeneration plant burning fossil fuels but
increasingly biomass, although heat-only boiler stations, geothermal heating and central
solar heating are also used, as well as nuclear power. District heating plants can provide
higher efficiencies and better pollution control than localized boilers. According to some
research, District Heating with Combined Heat and Power - CHPDH is the cheapest
method of cutting carbon, and has one of the lowest carbon footprints of all fossil
generation plants.
