1 Kajima s Infrastructure and Services Superior Quality with Added Value Providing Valuable Spaces for Everyone Trust is based on quality and the ability to provide added value. This is the starting point of craftsmanship and the guiding light for Kajima's design, construction, property development and property management activities. Kajima will continue to take advantage of its strengths to deliver premium-quality projects with added value, always striving to earn trust with a spirit of true craftsmanship. Shibaura Island Kajima leverages its superior design and construction services to create pleasant, safe and secure community spaces that enhance the value of the surrounding urban environment. Restoring industrial land for the community The role of the waterfront regions that once supported Japan s rapid economic growth as centers for maritime transport is evolving with the changing industrial structure. The Shibaura Island project transformed the Shibaura area (Minato-ku, Tokyo), which was an urban area with few ties to the community, into a peoplefriendly island of lush greenery and plentiful water, now home to about 10,000 people in 4,000 households. Shibaura Island was designated as the first high-rise residential development area under Japan s City Planning Act. Kajima participated in the plan to redevelop this urban area in a collaborative effort including public and private organizations. Kajima designed and constructed three of the four blocks in the project, primarily in the ultra high-rise residence area, and also designed and built part of the seawall. Creating comfortable and secure homes for long-term livability Kajima was convinced that, when providing such a large number of homes in a prime urban location like Shibaura Island, the buildings had to not only deliver the comfort and safety that Kajima s ultra high-rise residences are known for, but also anticipate and provide for future lifestyles.

2 Island s ultra high-rise condominiums, Kajima adopted a double-tube structure and clearly demarcated the basic structure, facilities and interiors so that residents could select from a variety of dwelling unit plans and room layout could even be changed in the future. Kajima also included basic functions to ease daily life for the elderly and created airtight and highly insulated buildings in conformance with Japan s housing performance label system for design and construction. In addition, Kajima envisioned the future comfort of these homes by incorporating the Kajima IT Condominium System, which provides security and convenience and also improves building management. In developing this project, Kajima succeeded in creating an area where a large population can live comfortably for the long term, going far beyond merely enabling temporary prosperity. Although each block of the project s urban area was developed independently, the layout, external appearance and plans for outdoor facilities were coordinated to create a rich and varied living environment for the entire area. Thanks to the expansive exterior space, a diverse community families, elderly people, residents with pets, and many others now enjoys an urban oasis spreading out beneath the windows of every home. A new message for Tokyo Even by Tokyo standards, this is a major development project that has brought considerable value to both Shibaura Island and the surrounding area. One example is the splendid use of the water there. To achieve this, Shibaura Island, seen from the water Exterior space seems boundless Air Terrace, a commercial facility, adjacent to Air Tower the first of the Tokyo Metropolitan Government s Canal Renaissance Promotion Zones, Kajima communicated closely with government agencies, found solutions for various regulatory and construction issues, and built a waterfront cityscape unlike any before it. Commercial facilities and open-air terraces feature cafes where people can relax and look out over the water. At the nearby floating pier, both tourists and local residents use the regularly scheduled water buses. Tokyo has long been a place where people talk about their urban lifestyles in terms of a city located on dry land, but Kajima has now created a new waterborne district, adding a whole new dimension of value to this magnificent city. Kajima s job is to make structures featuring low environmental impact, high functionality, and long service life. The company focuses not just on what is needed at the present, but also on the quality that will be called for by future generations. A community built to last just keeps getting better as the years go by, and provides the type of environment that people truly desire to live in. Kajima recognizes that this is the kind of place that makes a city sustainable, and is dedicated to creating more of these truly high-quality urban environments. KAJIMA CSR REPORT

3 A New Subway Hub in Shibuya for Tokyo Metro s Fukutoshin Line and Tokyu Railway Subterranean development in urban areas often looks like a battle with underground objects, including utility lines for electricity, gas and water and sewage systems, and optical fibers for telecommunications. Moreover, existing train lines and passenger movement must not be obstructed when constructing a new subway station. Kajima overcomes all these challenges using advanced technologies, and creates pleasant station spaces that provide both safety and comfort. Dramatically innovative design for the new Shibuya Station The new Shibuya Station, the origin point for the Fukutoshin Line, was built by a Kajima joint venture approximately 30 meters directly below the Tokyo Metro Hanzomon Line s Shibuya Station. The station needed a massive underground space for its four levels, two platforms and four tracks.

4 Kajima started building this underground space by driving piles into Meiji Dori Avenue, one of Tokyo s busiest trunk roads, to construct an underground wall and an open cut tunnel. Excavating directly under the Hanzomon Line s station was the biggest challenge, but Kajima overcame this by digging out eight columns of pilot tunnels immediately below the existing station structure, and then installing a total of 112 steel piles. The steel-frame beams were laid parallel with the pilot tunnels and mounted on the piles so that eight columns of steel-frame beams supported a station structure with a total weight of 24,500 tons. Escalator in the Underground Spaceship The massive underground space, known as the Underground Spaceship, was designed by architect Tadao Ando to resemble a spaceship floating deep below ground. This underground spaceship, which is encompassed by an elliptical capsule 80 meters long and 24 meters wide, uses a natural ventilation system and a radiant cooling system that saves about 1,000 tons of carbon dioxide emissions annually. Tunnel between stations uses new environmentally friendly technology The Kajima joint venture was responsible for excavating the span between Meiji-jingumae Station and Shibuya Station, equivalent to meters out of the 8.9 kilometers in tunnels of the new route between Ikebukuro and Shibuya. A variety of measures were taken during construction to reduce the environmental impact. Kajima has developed a technique called the Excavation Method of Adjustable Cutter (EX-MAC) to reduce the volume of soil unearthed during construction, introducing a new shield machine that flattens the tunnel cross-section vertically from a circular shape (composite circular shape) for this project. This reduced the cutter excavation cross-section by about 10 percent and decreased the volume of concrete required for filling by about 40 percent.

5 Senayan Project: A Massive Asian Development Project Senayan Square, located in the center of Indonesia s capital city of Jakarta, is a mixed-use commercial facility built on a vacant lot that had previously been home to an aging sports facility. This approximately 20- hectare site includes the Plaza Senayan shopping mall with a floor area of 100,000 square meters, two office buildings and two high-rise luxury condominiums. P.T. Senayan Trikarya Sempana (STS), one of Kajima s Indonesian subsidiaries, is responsible for this urban redevelopment project. Senayan Square is a buildoperate-transfer (BOT) project for the Indonesian government in which STS develops and manages the facility and then transfers it to the government at no cost after 40 years. Developing vibrant centers for community life Kajima is committed to good corporate citizenship, and is dedicated to growing side by side with local Central Senayan 1 (left) and Central Senayan 2 (right) communities by creating outstanding commercial facilities. Kajima also regularly supports cultural and artistic events and philanthropic initiatives. One of Kajima s cultural initiatives is the Khatulistiwa Literature Award, launched in alliance with local Indonesian publishers and novelist associations in The prize is awarded every year to the best works of literature and poetry written and published by Indonesians. The winning pieces are translated into English so that they can be introduced to a foreign audience. Since 2000, Kajima has planned and administered a fashion design contest in affiliation with a French clothing design school to encourage young Indonesian designers. The winners are given a scholarship to attend design school as well as living allowances. Senayan Square Overview In addition, Kajima makes the atrium of the shopping mall available for seasonal concerts and ballet presentations by children from orphanages. Senayan Square continues to grow At the end of 2007, the second office building was completed in Senayan Square, and due to the high occupancy rate, construction of a third office building will begin in Shopping Mall Plaza Senayan Kajima will continue to give back to local communities, not only by developing and operating excellent facilities, but also by creating new ways to enable more people to enjoy a comfortable life.
