Palm Island Construction
Construction on the palm islands began in 2001. Divers surveyed the seabed and workers 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 ofwater 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 [source: The Palm
Jumeirah]. Vibro-compaction increases the density of loose sand by saturating it with jets of water and
vibrating it with probes [source: TerraSystems].
To get the complex shape just right, designers and contractors use Differential Global Positioning
Systems (DGPS) to plot the palm and ensure the sand placement within 0.39 of an inch.
Palm Jumeirah is already packed with villas and hotels, with some early buyers complaining that the
plots are more closely spaced than they were led to believe. Buyers are a mixture of long-term
residents, vacationers and speculators hoping to cash in on skyrocketing prices. When the island is
complete, Nakheel expects 120,000 residents and workers plus as many as 20,000 tourists a day.
Construction workers lived on the fronds and in anchored cruise ships while building the island.
To facilitate tourism and make life easier for residents, the six-lane Sub-Sea Tunnel connects Palm
Jumeirah to the mainland. Workers used a dam to drain the area and excavate the seabed before
rereleasing the water. Developers have plans for a four-stop monorail that will race the length of the
palm.

THE PALMS AND THE ENVIRONMENT
Although the development company, Nakheel, took steps to minimize the environmental effects of
construction by transporting fish and marine animals outside of the palms' breakwaters, the islands
have still harmed the area's marine environment. Rocks and sand buried oyster beds and coral reefs
and altered currents eroded the mainland shore. Meanwhile, the owners of once-desirable shore
properties complain that the islands destroy their view.

Introducing the world’s longest underwater gas pipelineAs the global demand for energy continues to rise, so does the demand for bigger and longer conduits for the transportation of gas. One such conduit is the new 745 mile-long Norway’s Ormen Lange natural gas pipeline. This pipeline is constructed for exporting of gas from the Norway’s Ormen Lange, one of the largest natural gas reserves of the world
to the national Transmission system in the United Kingdom. Built at a total cost of 1.7 billion pounds ($2.6 Billion), the pipeline is about 725 miles (1,166 km) in length and has a carrying capacity of 26 billion cubic meters per year.
As in any other project of similar grandiosity, construction of this pipeline presented some unique challenges. One particular hurdle was the drilling conditions which comprised of rocky and uneven seabed beneath the North Sea. These conditions, coupled with the ever-present tectonic movements, ridges and existing pipelines also added to the factor of disadvantage. To access the gas reserves in the Ormen Lange, ground breaking work was required with developer having to use unmanned modules and building equipment to place the platform on the ocean floor. With a projected output of 70 million m3, the gas extracted from the Ormen Lange is entirely for transport, mostly through a network of seabed pipelines laid in rugged seabed terrain.
Super Pipeline Gas pipeline from Norway to Great Britain
Super Pipeline Gas pipeline from Norway to Great Britain
Located on the west side of Landscape Avenue in the Olympic Green and to the west of National Stadium (Bird's Nest), it contains the official 2008 Olympics swimming facility. The construction started on December 24th, 2003 and was finished on January 1st, 2008. It measures 177 meters (194 yards) long, 177meters wide, and 30 meters (98 feet) high and covers an area of 62,950 sq meters (75,287 sq yard). It has four floors: one at street level, two above, and one below. Its floor space reaches 79,532 sq meters (95,119 sq yard), while the below street level area is no less than 15,000 sq meters (17,939 sq yard). The one below served as the service area during the Olympics. The first floor is for tourists. The auditorium is on the second floor with 6,000 fixed seats (2,000 of which are movable), and 11,000 temporary seats. The third floor is strictly for business.
Design Idea
National Aquatics Center
The design combines modern technologies with Chinese traditional values. In tradition, Chinese conceptualized a square Earth and a round Heaven, and this formed the design's central theme. Moreover, the cube shape dominates ancient urban buildings. Its design is of traditional style to meet all its functional requirements. The Blend of Architecture & Advanced Technology
Designed by Chinese and Australian, it is the first building in the world built upon "the soap bubble" theory, and sports a polyhedral steel-framed structure.The ETFE (the ethylene-tetrafluoroethylene copolymer) membrane insulates it. This advanced membrane structure is formed by 3,065 bubble-like pneumatic cushions of all sizes. It becomes the first large-scale public project coated with the membrane, and it also has set up a new world record for its massive deployment.
It looks like a huge blue box, from which it takes its nickname: the Water Cube. It is blue in order to reflect sunlight. It shines in the sunlight like a pearl in water. From the inside, you may discover that the pneumatic cushions of all sizes are just like sea bubbles.
Various high technology and green technology are present in its construction. Popular Science magazine chose it the Best of What’s New of 2006.
