Enhanced Safety and Efficiency,

Over the past century, Hazama has been involved in numerous major dam projects in Japan and overseas. Through these projects, Hazama has developed and introduced unique construction methods and accumulated a comprehensive technological resources that ensure the safe and efficient completion of long-term dam construction projects. In recent years, Hazama has focused on the improvement of safety and efficiency through the robotization and automatization of dam construction. It continues to apply its vast experience and powerful technology development capabilities to the creation of construction systems based on increasingly sophisticated mechanization know-how and information technology.

Hazama targets safe, efficient construction methods through the introduction of various kinds of automated dam construction technologies, as in the Satsunai-gawa Dam

Protecting the Environment

The Misogawa Dam is a representative large-scale, rock-filled dam in Japan

Hazama takes special care to ensure that the environmental impact of major dam construction projects is kept to a minimum. It has developed environment assessment technology that enables it to forecast and minimize the environmental impact of dam projects. To ensure scenic harmony, it has also developed a computerized scenery design system and an area pot planting system used to maintain visual harmony between structures and surrounding forest areas. The system has been used on a number of projects.

Hazama's concern for the environment is also reflected in its efforts to recycle timber concrete forms and develop alternative materials. The reduction of tropical timber use is the most important example of Hazama's commitment to environment-friendly construction.

Major Dam Projects

The Kannagawa Dam is a lower dam for pure pumped storage power station which maximum output is the world's largest in its type

Hazama has demonstrated its advanced know-how on numerous major dam construction projects, such as the Sabigawa Dam and the Hattabara Dam in Japan.
Hazama has been involved in a number of large-scale dam construction projects in other countries too, including Malaysia's Temengor Dam, the Da-Nhim Dam in Vietnam, and the Nan Ngum Dam in Laos. These dams, which were built in the 1960s and 1970s, have since helped to provide the driving force for economic development in the countries concerned. Among the many projects completed in recent years are Bili-Bili Multipurpose Dam in Indonesia, which is used for both irrigation and power generation, and the Nam Song Diversion Dam in Laos, which is used as a reservoir and power generation facility.
