MEGA STRUCTURE

A megastructure is an artificial construct of enormous size. The term is informal but generally megastructures are at least a few thousand kilometers in size along one dimension. Megastructures appear most frequently in science fiction, though arguably the Great Wall of China is a megastructure. The Great Wall can be seen from low earth orbit, but so can highways, fields of crops, and large buildings. Low earth orbit is only 200 km (125 mi.) up so this makes sense. Megastructures are most frequently seen in science fiction, and it seems like only a matter of time until our civilization starts to build them. A megastructure is meant to be a contiguous, self-supported entity - that is, not composed of an aggregate of smaller constructs.

I think this project is an amazing feat. Its like making a dream structure come true. Looks like a really cool place. If i am really rich i will definitely visit. But i wonder how this structure will be a solid structure forever...I mean wont the sea wash away the sand slowly...haha call it paranoia... really a great video shd watch also...

The Palm Islands in Dubai are the three largest artificial islands in the world. Each settlement will be in the shape of a palm tree, topped with a crescent, and will have a large number of residential, leisure and entertainment centers. The Palm Islands are located off the coast of The United Arab Emirates in the Persian Gulf and will add 520 km of beaches to the city of Dubai.

Between the three islands there will be over 100 luxury hotels, exclusive residential beach side villas and apartments, marinas, water theme parks, restaurants, shopping malls, sports facilities and health spas. The creation of The Palm Jumeirah began in June 2001. Shortly after, The Palm Jebel Ali was announced and reclamation work began. In 2004, The Palm Deira, which will be almost as large in size as Paris, was announced. Palm Jumeirah is currently open for development. Construction will be completed over the next 10-15 years.

The first island build is island Palm Jumeirah, 2nd island is Palm Jebel Ali and 3rd island is Palm Deira.

Construction

The Palm Islands are artificial peninsulas constructed of sand dredged from the bottom of the Persian Gulf by the Belgian company Jan De Nul and the Dutch company Van Oord. The sand is sprayed by the dredging ships, which are guided by DGPS, onto the required area in a process known as rainbowing because of the arcs in the air when the sand is sprayed. The outer edge of each Palm's encircling crescent is a large rock breakwater. The breakwater of the Palm Jumeirah has over 7 million tons of rock. Each rock was placed individually by a crane, signed off by a diver and given a GPS coordinate. The Jan De Nul Group started working on the Palm Jebel Ali in 2002 and finished by the end of 2006. The reclamation project of the Palm Jebel Ali includes the creation of a 4 km long peninsula, protected by a 200 m wide and 17 km long breakwater built around the island. 135,000,000 m³ of rock, sand and limestone were reclaimed (partly originating from the Jebel Ali Entrance Channel dredging works). There are approximately 5,000,000 m³ of rocks in the slope protection works.

Palm Jumeirah

The Palm Jumeirah ( Coordinates: [show location on an interactive map] 25°06′28″N, 55°08′15″E ) consists of a trunk, a crown with 17 fronds, and a surrounding crescent island that forms an 11 kilometer-long breakwater. The island itself is 5 kilometers by 5 kilometers. It will add 78 kilometers to the Dubai coastline. The first phase of development on the Palm Jumeirah will create 4,000 residences with a combination of villas and apartments over the next 3 to 4 years.

Residents began moving into their Palm Jumeirah properties at the end of 2006, five years after land reclamation began, according to project developer Nakheel Properties. This signaled the end of phase one of construction, which includes approximately 1,400 villas on 11 of the fronds of the island and roughly 2,500 shoreline apartments in 20 buildings on the east side of the trunk.

Nakheel Properties will mark the arrival of the first residents by bringing one of the world's largest airships to Dubai. It has agreed to a deal with Airship Management Services Inc. for a 197 feet (60 m) long, 250,000-cubic-foot (7,100 m3) Skyship 600 dirigible.

According to Nakheel Properties officials, the process of adding 78 kilometers of beach is under way, while eight of the 32 hotels on The Palm Jumeirah have begun construction, including the Taj Exotica Resort and Spa, which is planned for completion in late 2008 or early 2009. The first phase of Atlantis, The Palm, is scheduled to be completed by December 2008.

The "Golden Mile", the strip of land located along the center of the trunk overlooking the canal, is set for completion in the first quarter of 2008. Construction has also begun on the Palm Jumeirah Monorail, which will take three years to complete and will serve as a transit system between the Gateway Station at the trunk of The Palm Jumeirah and the Atlantis Station on the crescent.

The Palm Jebel Ali began construction in October 2002 and is expected to be completed in mid 2008.[1] The Palm Jebel Ali is expected to accommodate 1.7 million people by 2020. Once it has been completed, it will be encircled by Dubai Waterfront. The project, which is 50 percent larger than the Palm Jumeirah, will include six marinas, a water theme park, 'Sea Village', homes built on stilts above the water, and boardwalks that circle the "fronds" of the "palm" and spell out an Arabic poem by Sheikh Mohammed bin Rashid Al Maktoum

Take wisdom from the wise

It takes a man of vision to write on water

Not everyone who rides a horse is a jockey

Great men rise to greater challenges

As of early October 2007, construction of the island was on schedule. The breakwater was completed in December 2006, and infrastructure work began in April 2007. Major construction will not begin until most of the infrastructure work is complete.

One of the first buildings on The Palm Jebel Ali is already known. Nakheel invited several architects to design a building on a 300,000m² area. The winning design was a building by Royal Haskoning, who also worked on several other projects in Dubai. The building can be seen here.

In 2012, the first phase of four theme parks will open on the Crescent. These parks, which together will be called "World of Discovery," will be developed and operated by the Busch Entertainment Corporation. The parks include SeaWorld, Aquatica, Busch Gardens and Discovery Cove. The World of Discovery will be located at the top of the Crescent, which will form into the shape of an orca (reminiscent of Shamu).

Palm Deira

The Palm Deira was announced for development in October 2004. Upon completion, it will become the world's largest man-made island, housing more than a million people. Although no timetable for completion has been announced, it is expected to be finished by 2015. This island is 8 times larger than the Palm Jumeirah, and 5 times larger that the Palm Jebel Ali. Originally, the design called for a 14km (8.7 mile) by 8.5km (5.3 mile) island with 41 fronds. Due to a substantial change in depth in the Persian Gulf the further out the island goes, the island was redesigned in May 2007. The project then became a 12.5km (7.76 mile) by 7.5km (4.66 mile) island with 18 larger fronds.[2] It will be located alongside Deira.

By early October 2007, 20% of the island's reclamation was complete, with a total of 200 million cubic metres (7 billion cubic feet) of sand already used. Then in early April 2008, Nakheel announced that more than a quarter of the total area of the Palm Deira had been reclaimed. This amounted to 300 million cubic metres (10.6 billion cubic feet) of sand. Since the island is so large, it is being developed in several phases. The first one is the creation of Deira Island.[2] This portion of the Palm will sit alongside the Deira Corniche between the entrance to Dubai Creek and Al Hamriya Port. Deira Island will act as "the gateway to The Palm Deira" and help to revitalize the aging area of Deira. By early April 2008, 80% of Deira Island Front's reclamation was complete.

Interesting Facts About Palm Island

• Due to its immense scale and unique shape, The Palm, Jumeirah and The Palm, Jebel Ali are visible from space with the naked eye.

• The creation and development of The Palm is an unparalleled feat of design and engineering. The Palm is destined to be like no other place on earth.

• The brilliance of The Palm is both in its tribute to the date palm tree, referred to as 'bride of orchard', and in its ideal geometry for creating maximum beach frontage.

• Each island will add 60 kilometres of shoreline to Dubai, increasing the UAE's beachfront by an extraordinary 166%.

• Rocks weighing a total of 7 million metre cubed (per island) are being brought in from sixteen different quarries throughout the United Arab Emirates.
• The Palm comprises approximately 100 million cubic metres of sand and rock.

• If all the fill materials used to build one Palm island were placed end to end, a wall two meters high and half a metre thick could circle the world three times

• Dredges play a prominent role in building The Palm. Sand is first dropped into place and piled at a specific angle of repose, ensuring it will hold its place.

• After the initial dumping of sand, a dredger brings the sand level to the surface with a process called "rainbowing", which literally sprays the sand into proper position.

• The Crescent surrounds the island and acts as a breakwater - able to withstand a 4m wave. It is built from the bottom up, beginning with the sand, geotextile fiber, small rocks, and then medium sized rocks, once above water.

• Expert Divers examine rock placement underwater to ensure correct positioning. Divers are also used to review placement of geotextile.

Over 100 studies from transportation, marina design and water supply to technology and civil works have been completed to assess and ensure The Palm's feasibility.

Palm Island – Dubai – Mega structure Palm Island – Dubai – Mega structure

The Palm Islands are artificial islands in Dubai, United Arab Emirates on which major commercial and residential infrastructure will be constructed. The islands are the largest land reclamation projects in the world and will result in the world's largest artificial islands. They are being constructed by Nakheel Properties, a property developer in the United Arab Emirates, who hired the Dutch dredging and marine contractor Van Oord, one of the world's specialists in land reclamation. The islands are the Palm Jumeirah, the Palm Jebel Ali and the Palm Deira.

The islands were commissioned by Sheikh Mohammed bin Rashid Al Maktoum in order to increase Dubai's tourism. Each settlement will be in the shape of a palm tree, topped with a crescent, and will have a large number of residential, leisure and entertainment centers. The Palm Islands are located off the coast of The United Arab Emirates in the Persian Gulf and will add 520 km of beaches to the city of Dubai.

The first two islands will comprise approximately 100 million cubic meters of rock and sand. Palm Deira will be composed of approximately 1 billion cubic meters of rock and sand. All materials will be quarried in the UAE. Between the three islands there will be over 100 luxury hotels, exclusive residential beach side villas and apartments, marinas, water theme parks, restaurants, shopping malls, sports facilities and health spas.

The creation of the Palm Jumeirah began in June 2001. Shortly after, the Palm Jebel Ali was announced and reclamation work began. The Palm Deira, which is planned to have a surface area of 46.35 million square metres and which the developer, Nakheel, claims is a surface area larger than that of Paris, began development in 2003. Construction will be completed over the next 10-15 years.
