Significant Milestones Passed in the Dubai Metro Project

The city of Dubai in the United Arab Emirates is literally bristling with tower cranes--in fact, it is estimated that Dubai alone accounts for approximately one-fifth of the world's fleet of tower cranes. Bolstered by rising petroleum revenues over recent years, Dubai's construction boom continues unabated.

In response to rapidly increasing demand for passenger transport, the city has embarked on the Dubai Metro Project, which will see the construction of a driverless, fully automated urban transit system. Kajima, as part of a five-company consortium undertaking the first and second phases of the project, is involved in all facets of the project's design and construction, from civil engineering through to the metro management system.

The current project comprises the Red Line (first phase) linking Dubai International Airport with Jebel Ali Free Zone (JAFZ), and the Green Line (second phase) covering the central part of Dubai city. Incorporating both elevated and underground portions, these two lines will run to a combined length of 70 kilometers (43.5 miles), making it the world's longest driverless transit system.

On January 10, 2007, a ceremony was held to mark the commencement of tunneling work for the Dubai Metro's Red Line. His Highness Shaikh Mohammad Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, pressed the button to launch the operation of the first tunnel boring machine (TBM), which will bore a tunnel stretching 3.9 kilometers (2.4 miles) and will be used to bore through relatively soft geological structures, such as under Dubai Creek, as well as sections passing directly beneath existing buildings. Including the TBM currently in operation, the consortium plans to use a total of three TBMs during the first and second phases of the project. Construction work has also begun on pier supports and elevated decks for the viaduct sections of the line, overground and underground stations as well as two depots.
These piers will support the Red Line's viaduct sections.

For the Green Line, prior to the main construction stage, preparatory works are now under way. These include geological surveys, moving work for existing underground facilities and applications for the acquisition of land needed for construction work. In Dubai, where summer temperatures soar to around 50 degrees Celsius (122 degrees Fahrenheit), the climate at this time of year is relatively mild. As work progresses in order to meet the Red and Green Lines' scheduled opening dates of September 2009 and March 2010, respectively, everyone involved in the project is working hard to overcome an array of difficult construction challenges.

Kajima Exhibits the Latest Transparent MRI Room at RSNA 2006

Kajima exhibited its unique transparent magnetic resonance imaging (MRI) room at the 92nd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA 2006), held from November 26 to December 1, 2006, at McCormick Place in Chicago. The transparent MRI room was developed using Kajima's proprietary transparent shielding technology to create a friendly, open environment for patients receiving MRI scans.
Kajima Exhibits the Latest Transparent MRI Room at RSNA 2006
RSNA 2006 was a major international conference that drew over 70,000 medical and healthcare professionals from around the world. The majority of conference participants work in the radiology and diagnostic imaging fields. During the convention, more than 3,000 participants visited the Kajima exhibition booth, including specialist medical practitioners from such world-renowned facilities as Johns Hopkins Hospital (Baltimore, MD), University of Massachusetts Memorial Medical Center (Worcester, MA) and St. Luke's International Hospital (Tokyo, Japan). Visitors to the booth were able to view a scale model of the transparent MRI room system and related panel displays as well as participate in Kajima's product seminars.

Rather than employ conventional magnetic shielding technology, which requires the entire room to be enclosed within magnetic shielding plates and walls, the transparent MRI room utilizes Kajima's original "open magnetic shield" system based on rows of magnetic shielding strips spaced at wide intervals. This system achieves shielding performance equal to that of traditional encapsulated shield methods. The transparent MRI room is currently used by over 10% of national university hospitals in Japan. Kajima plans to develop overseas markets for this product, particularly markets in North America and Asia from which the Company has fielded a large number of business inquiries.

Concrete That Will Last for 10,000 Years:
The Development of EIEN


Concrete has a long history, having been used in ancient Roman times for temples, arenas, aqueducts, and other such large-scale construction projects. This "ancient concrete" used around 2,000 years ago differs somewhat from the concrete of today because it was mixed with volcanic ash and lime.

Recently, concrete approximately 5,000 years old that closely resembles that used in ancient Rome was uncovered virtually intact from ruins on the outskirts of the Chinese city of Xi'an. The surface of the concrete was protected by a chemical reaction called carbonation, which almost completely prevented water or salt from reaching the interior, and allowed the concrete to retain its soundness.

Kajima is now working in cooperation with Denki Kagaku Kogyo and Ishikawajima Construction Materials to develop a new type of high-durability concrete with special admixtures and carbonation curing called EIEN(Earth, Infinity, and ENvironment) that is intended to last for 10,000 years. (Eien also means "eternal" or "permanent" in Japanese.) Applying the principle of the carbonization of the ancient concrete, a special admixture is added that reacts with carbon dioxide but not with water, densifying the surface of the concrete and making it possible to enhance its durability.

Such concrete would make it possible to significantly reduce the number of times bridge piers or underground structures would need to be repaired, and the concrete could also be used for facilities that need to be maintained for long periods.

The fusion of ancient wisdom and modern technology is bringing closer the kind of "everlasting social infrastructure" embodied in the name EIEN.

Stunning Animation Depicts a Fresh Vision for the Future


Kajima recently partnered with one of the world's most celebrated animation production houses, Production I.G, Inc., to produce a new corporate advertising campaign. The campaign features a striking illustration that depicts a futuristic cityscape.

The illustration, an original by Production I.G's top art director Shuichi Hirata, depicts--in elaborate detail-- an urban scene from the near future: a city that provides all the functions of an advanced metropolis while maintaining a symbiotic relationship with the natural environment.

Production I.G is widely recognized as one of the world's premier animation studios and is celebrated for the high quality of its work. It has built up an impressive array of domestic and international awards and achievements. Through its 1995 release Ghost in the Shell, Production I.G became the first Japanese animation studio to gain a No. 1 hit ranking on the Billboard Top Video Sales Chart in the United States. In 2004, Production I.G's film Innocence was the first Japanese animated movie to compete for the Palme d'Or at the Cannes Film Festival. Shuichi Hirata was in charge of the movie's stunning background art.

The new advertising campaign is based on Kajima's wish to play an essential role--meeting the needs of people, society and the planet. From this concept was born the powerful slogan, "NEED KAJIMA." Added to this was the copy "For a livable future," which expresses Kajima's corporate stance of working-- now and in the future--to create a society based on high-quality living and environments. The advertising campaign is being conducted across a wide range of media.
