The Best Modern Development Accomplishment Of Dubai

A short distance off the shore of Dubai are several beautiful islands in the form of gigantic palm trees: Palm Jumeirah, Palm Jebel Ali, and Palm Deira, still under construction. Each is comprised of peninsulas extending from a trunk attached to the Dubai coastline, and capped further outward by a great seawall for shelter. It must have taken a lot of geotechnical consultants to make the necessary examinations of the site’s seabed, each geotechnical consultant an expert in seabed engineering. Because creating an island from shifting undersea sand will require a lot of engineering expertise even before whatever can be put down on record, before making any physical construction.

The Palm Jumeirah Crescent or breakwater is just 13 feet higher than the sea level at ebb tide, and rises from 34 feet of water at its deepest point. Its engineers state that it is elevated enough not to go below surface in the rise of the sea level when global warming really happen, or any tsunamis that might form in the Persian Gulf. The breakwater is formed from rocks blasted from the mountains. At its base is sand covered by a geo-textile or woven fabric to inhibit the sand from moving out. Anchoring down this ‘wrapped’ sand is a stratum of one-ton boulders, over which two strata of six-ton stones sit to form the top part.

The peninsulas jutting from the middle avenue are created also from sand taken from the seafloor and then vibro-compacted to support structures. Palm Jumeirah was created from 3,257,212,970.389 cubic feet of sand. Vibro-compacting is performed by filling up the sand with water then vibrating it via drills to make the sand settle more thickly. initially a probe is buried into the sand sub-surface through water filling and vibration. As the probe sinks to its desired depth, flowing sand is tossed down into the opening made by the vibrator probe. Thus a more solid zone of sand is created, sufficient to hold up structures.

However, vibro-compaction may be suitable only in uncontaminated sand where silt content constitutes only 15% at the most.

In eery peninsula or frond are two lines of private estates or structures for the awfully rich, and anyone can buy his property there. Palm Jumeirah is expected to house 120,000 homeowners and workers, plus another 20,000 tourists each day. So it is not really a small island where solitude can be obtained, but a gigantic self-sufficient suburbia of the really, really wealthy. There are at present residents living in the islands: real property owners, transients, businessmen and workers giving last touches to a few parts of the built up areas. A six-lane avenue today serves as the transportation artery in and out the fronds, but in the last stages, inhabitants will also be serviced by a monorail.

Palm Jumeirah and the three other man-made islands exemplify what modern engineering backed by a lot of money can accomplish. While land building from the sea to create islands may not be a novel idea since it has been made numerous instances before, the project’s massive size causes it so.
