| Twin Tower Project: Kajima Wins Contract for Singapore's Largest Office Building Kajima Overseas Asia Pte Ltd (KOA), in a joint venture with the Singapore construction company Tiong Seng Contractors, was awarded through general bidding a S$558.38 million contract tendered by BFC Development Pte Ltd for construction of the Marina Bay Financial Centre building. BFC Development Pte Ltd is a joint venture between Keppel Land Ltd of Singapore and two of Hong Kong's largest property developers, Hong Kong Land and Cheung Kong (Holdings) Ltd. KOA has obtained ISO9001, ISO14001, as well as Occupational Health and Safety Management OHSAS18001 certification, and has received a number of awards for its Quality Control, Safety Management, and Environmental Management systems. In addition to KOA's experience, expertise and competitive edge, the detailed nature of KOA's proposal, which included a description of the type of underground construction methods that would be needed to cope with the soft ground at the landfill that is to be the site of the project, drew high praise and was instrumental in helping KOA to win the bid. The Marina Bay Financial Centre will consist of twin towers, one 52 stories (243 meters, or 800 feet) and the other 32 stories (191 meters, or 630 feet), and will be constructed in the heart of Singapore's marina district. The basic design was produced by U.S. architect Kohn Pedersen Fox, while the structural and facility designs were consigned to DCA Architects and Meinhardt of Singapore. Construction on the building will begin in September 2007, with completion planned for March 2010. Financial institutions from Singapore and around the world are the anticipated tenants. In recent years, government and the private sector have joined forces to develop the marina district, which is attracting a steady stream of large-scale local and international construction projects. This new office complex is sure to become a symbol of Singapore's status as one of the world's leading financial hubs. |

| A New Runway at Haneda Airport: Improving the Convenience to Travelers According to the 2006 survey by the Airports Council International, Haneda is the world's fourth largest airport, with approximately 65 million passengers arriving and departing annually. Expansion work that will include construction of a fourth runway (Runway D), conducted through a consortium led by Kajima, began at the end of March 2007. The project involves construction of a 2,500-meter (8,200- foot) runway and taxiway planned at the mouth of Tama River east of the existing airport. The runway will be constructed on a combined reclaimed island and piled elevated platform, linked by a taxiway bridge to the existing airport. Most offshore airports constructed have used reclaimed islands, but for this project a hybrid design was adopted that includes a piled elevated platform to avoid blocking the outflow from the Tama River. In March 2005, Kajima was selected to head the consortium for construction of Runway D. Detailed design work was conducted and completed in December 2006, and preparatory work including additional soil investigation has been conducted. The project will proceed on a 24-hour shift schedule, with due care taken to minimize interference with daily airport operations and shipping traffic along passage No. 1 and the Tama River. The runway is expected to open at the end of October 2010. The expansion of Haneda Airport will increase its takeoff and landing capacity from 296,000 flights annually to 407,000. Of these, approximately 30,000 are international flights, mostly short-distance routes from nearby Asian countries. In addition to regular international flights, the new runway will make it possible to handle increased future demand for domestic flights. This is expected to significantly improve the convenience to travelers. |

| Protecting High-Tech Fab from Earthquakes: Base-Isolated, New Frame Construction System for Multi-Story Structures As electronic devices and the equipment that make them have become larger, the fabs that manufacture these products increasingly require large open spaces in order to have the flexibility to adapt to production line changes. Furthermore, production fabs handling precision devices or chemical agents must be free of even micro-vibrations, with the securing of seismic safety an important factor. The initial investment for such factories is of course considerable, and in the event of an earthquake, in addition to the direct damage to the fab building or equipment, there is a risk of immense indirect harm to a company, such as the decline in sales as production comes to a halt. Kajima has developed new types of frame construction technology that protect against micro-vibrations even in multi-story structures with large-span constructions. These were displayed in April 2007 at FINETECH Japan, the world's largest flat panel display (FPD) industry exhibition, drawing interest from many visitors. One of the patented frame constructions is called the Catenary arch construction method. This system maintains rigidity even with a small quantity of steel frames used in multi-story structures, and is highly resistant to micro-vibrations even with a span of 40 meters (131 feet). Compared to traditional truss frame constructions, there are fewer diagonal braces, allowing use of underfloor space to be maximized for ducts or pipes, even in clean rooms. Other additions to Kajima's lineup include the KW frame construction and MX frame construction. With these technologies, alteration of the shape of the structural frame allows for variations in the frame construction. The KW frame construction further lowers costs and is easier to build, while the MX frame construction (patent pending) allows the frame height and the height of the building to be kept to a minimum. These technologies allow Kajima to offer the optimal frame construction system to meet a wide range of clients' needs, while also helping to protect life and valuable equipment from earthquake damage. |

| Diana Garden Hiroo Wins IALD Award The Residential Lobby of the Diana Garden Hiroo, designed and built by Kajima in cooperation with lighting designer Reiko Chikada, was recently awarded the IALD Award of Merit at the 24th International Association of Lighting Designers (IALD) Awards, in recognition of its outstanding lighting design plan. The IALD, an organization established by lighting designers, is known for its rigorous selection criteria for this award. It is a prestigious honor intended to showcase outstanding lighting design on an international level. Diana Garden Hiroo is a 10-story luxury condominium complex located in the heart of Tokyo, near numerous embassies and universities in an area brimming with international culture and atmosphere. Designed and built by Kajima, this distinctive condominium expresses a fusion of contrasting Japanese and foreign cultures, along with modern and traditional elements. The complex diversity of the exterior of the building is in harmony with the quiet neighborhood. The lighting plan for the entranceway was developed in cooperation with Reiko Chikada Lighting Design, Inc. The lobby space, which blends a checkerboard pattern with a variety of other motifs, is accentuated by striking luminous pillars. It provides an attractive approach to a unique communal residence that assumes the flavor of an individual residence. |
