4Tokyo Bay Aqua-Line (1997)Named the Apollo Project in Civil Engineering, this project was completed by integrating the cutting-edge technologies and knowhow available at the time; by developing and applying numerous new construction technologies/methods; and by overcoming the countless challenges posed by the natural conditions at the site, including the soft seabed, strong winds and tides, and earthquakes, as well as complications related to environmental concerns and measures to ensure the continuing safe passage of ships in Tokyo Bay.Urayama Dam (1997)Located in Chichibu City, Saitama Prefecture, this is Japan’s second-highest gravity dam. Utilizing the world’s longest layer construction method, the RCD method, the world’s first one-meter lift, and belt conveyor technologies to transport raw stone, aggregate, and concrete materials for the first time in Japan, this challenging project applied several unprecedented technologies. The dam is now a familiar site open to the public. Shizuoka Prefectural Fuji Swimming Pools (2001)With an external profile that recalls a giant waterdrop, this building contains swimming pools equipped with movable floors and walls that change depths and distances. The facility is open to the public, including children, adults, and the elderly, as a fully equipped sports center. In 2003, it served as the main venue for the Summer National Sports Festival held in Shizuoka Prefecture. 2003Celebrated 120th anniversary of the Company’s founding.Surikamigawa Dam (2006)This rock-filled dam with a center core, one of the largest in the Tohoku region, supplies city water, including drinking water and water for other everyday uses to three cities and four towns, including Fukushima City. It also provides irrigation for rice paddies and agricultural land along the Surikami River and Abukuma River to support the thriving agriculture of this region.2013Celebrated 130th anniversary of the Company’s founding.Wacoal New Kyoto Building (2016)Designed to serve as a new marketing base, the building with its external fins and other design features expresses tact, gentleness, refinement, and purity. Incorporating a toggle brace seismic damping structure, the building attained S rank class, signifying Superior quality by CASBEE.National Highway No. 45, Rikuzentakata Road (2018)This 10 km limited highway was planned as a leading earthquake disaster reconstruction project. We constructed the 7.0 km section on the side of Rikuzentakata. Completion of the road will strongly help afflicted areas move forward with local reconstruction and is expected to play a major role in the development of local industries encompassing Iwate and Miyagi prefectures.2019Formulated Medium-Term Five-Year Plan with the basic policy of establishing foundations for our status as a New Business Contractor.Mega Solar Park (2020)To make the most of renewable energy and to achieve carbon neutrality, we installed 122,000 solar panels on a vast 65 ha site developed as part of a mega solar power plant project with an output power of 45 MW in Miyagi Prefecture. Kesennuma Disposal Site (2022)The forest in the Kujo district and surrounding areas was cleared to make way for this new final disposal site for municipal solid waste. The entire structure involved the following work: 195,040 m3 of soil excavation and embankment, construction of a 410 m reversed T-type retaining wall, laying 23,792 m2 of waterproof sheets, installing 321 m of groundwater collection pipes, installing 2,017 m of guttering, construction of a 4,014 m2 concrete dam for the regulation pond used for disaster prevention, construction of a landfill gas treatment facility with five vertical pipes, and asphalt paving work for the 8,305 m2 passageway. We also constructed a 9,760 m2 storage facility covered with a roof (steel truss).(2011-)Transformation Period(1991-2010)Co-creation Period
