Download Palm Island

Introduction
 Dubai previously earned most of its income through
oil.
 But oil is not ever lasting.
 So Prince Sheikh Md. proposed construction of a
unique set of islands
 The Palm Islands are an artificial archipelago
(islands) in Dubai, United Arab Emirates.
 The palm islands is basically a group of three islands in
the shape of the palm topped with a crescent
 The islands are Palm Jumeirah, the Palm Jebel Ali and
the Palm Deira.
 The total sand and rock required by:
1)Palm JUMEIRAH: 100 million m3
2)Palm JEBEL ALI : 100 million m3
3)Palm DEIRA: 1 billion m3
Construction Steps
 Construction of Break Water
 Construction of soil bed.
 Construction of 4 lane bridges.
 Settlement of soil bed.
Breakwater required 5.5 million cu. m of
rock
This is enough to build 2 pyramids
These rocks were transferred from coast to
construction site on barges.
There was no use of concrete or steel to hold
these rocks, thus each rock should be of
appropriate size and strength to withstand the
ferocious sea.
It took 9 barges, 15 tug boats, 4 dredgers, 13
heavy land machines and 10 floating cranes were
used to construct massive sea wall.
The rocks were dropped accurately with the use
of Digital GPS coordinates.
 Soil from sea floor was chosen to build soil bed.
 This sand was much suitable then the sand of main land as:
1) coarse and more resistent to impact of load.
2) More economical
 They scoops up the sand from the gulf floor and transfered
with help of dredgers which took a total of 3 hrs.
 The process of spraying sand is called rain bowing.
Bridges
 Two 4 lane Bridges were made on break water to
provide fresh flowing water in the system.
 Twice a day, the tide enters under the bridges in the
system, pushing clean water around the spikes and
removing the stale water and thus provide natural
flow.
Settlement of soil bed
 The process known as vibrant compression was
chosen to both settle or compact the soil bed.
 In this method 2,00,000holes were made by 15
machines across the surface of island and vibrating
shafts compact the earth and more sand is filled after
each settlement until the area becomes rock solid.
 This process took 8 months to stabilise the bed.
Adds upto 520 kms of beaches to the city of Dubai.
Over 100 luxury hotels
Beach side villas
Apartments
Marinas
Water parks
Restaurants
Shopping malls
Health spas and sport facilities
the Palm Jumeirah Monorail, which will take three
years to complete and will serve as a transit system
between:
Gateway Station at the trunk of the Palm Jumeirah

and
the Atlantis Station on the crescent.
The Monorail opened on May 6, 2009, but only
utilized the Atlantis Hotel and Gateway Towers
Stations.
oIt was constructed with blasted mountain rock and is shaped like
crescent.
oThe crescent(breakwater) is 34 ft above the deepest point and 13 ft
above the sea level.
oTo prevent soil erosion a erosion preventing water permeable geotextile is used to cover the sand.
oSand is covered by 1 ton rocks and cap is covered by 2 layers of rocks
weighing 6 tonnes.
o Gaps(bridges) are provided in the bridges for avoiding stagnation of
water.
For getting a complex shape constructor and designer used Differential Global Positioning System to plot the island and 0.39 inch sand placement.
Palm Jumeirah island is made of ocean’s 3,257,212,970,389 ft3 and vibro
compacted sand.
By vibro compaction the density of the sand increases with the flow of
jet.
For getting a complex shape constructor and designer used Differential
Global Positioning System to plot the island and 0.39 inch sand
placement.
The island can be seen from the outer space because of its size.
Palm Island has a shoreline of 60 Kilometers which increases the costline
of UAE by 166 percent.
Palm Island is actually connected with the mainland of United Arab
Emirates.
Rock of 7 million cubic meters and sand of 32 million cubic meters was
required for making of each island.
The three islands are connected as one end to another
