The amazing technology that was used in the construction of Palm Islands in Dubai. In construction, technology may be used as means to perfect, accelerate the time of construction and perform the seemingly impossible. Palm Islands was a complex project in the sense that only natural materials were used and the shape was somewhat peculiar. This land reclamation project increased Dubai’s shoreline by 75km where 94 million cubic meters of sand and 5.5 million cubic meters of stone were used to create the palm shaped island on which luxury villas and hotels were to be later built, C.Gibling (2013, pg 4). This required special technology and techniques to ensure success of the project.
The first challenge was to collect sand and deposit it at certain areas in the sea. This was done using dredgers. Dredging according to the Oxford dictionary is to clear the bed of (a habour, river or other area of water) by scooping out mud, weeds and rubbish.
There are different types of dredgers, however, for the Palm Islands project, the trailing suction hopper dredge (TSHD) was used because it is the only non-stationary dredger. This is because the dredger had to move from the area of suction to the area of deposition. The trailing suction hopper dredge has suction tubes dragged over the seabed during dredging, dredge pumps to suck the material, hopper where the dredged material settles and a swell compensator to control the contact between the suction mouth and seabed when dredging. In as much as Dubai has plenty of sand since it is a desert, the right type of sand that was cohesive enough could be used and it was only found in the seabed.
To create the palm shape, rain bowing was done. The dredging ship is used fo...

- Before the islands were under construction along the coast of Dubai, many risks were analysed to understand if the project would be successful and to find faults before they would occur during the build. While many different problems were found and worked around to be minimised or removed entirely, the erosion of the shoreline was one that was not considering thoroughly at the beginning and started to show its true effect later in construction. Due to the nature of the shoreline, it was eroding before the islands were built (The National, 2010), cause the process to speed up to a rate that would start effecting building near the shore if it was not prevented....

An example of this is a city which 185 years ago was just a small fishing settlement (Dubai.com, 2015).

There is so much to see form the drop-dead architecture to the metro; from the vigorously kept grass to the natural desert, and of course the tantalizing advertisements. Whether it’s a new product or a new city you’ll see it… on cardboard. Oh, did I mention the expensive line-up of luxury cars that roam around too. The highway is surrounded by high rises and each one has its own unique architecture. Being a rather futuristic/touristy city all the buildings seem to have adapted a code....
