TECHNICAL RESEARCH INSTITUTE

“Advanced, trusted technologies that preserve rich natural environments for future generations.”

Asunaro Aoki Construction established the Technical Research Institute in 1993 in Tsukuba Science City, adjacent to the University of Tsukuba, in a nature-rich environment.
Currently, as the “Takamatsu Construction Group Technical Research Institute,” Asunaro Aoki Construction, Takamatsu Construction, and other group companies are engaged in technological development across all construction fields—including building construction, civil engineering, environmental technologies, and disaster prevention—aimed at enhancing corporate value.

Major Research Activities

The institute consists of the Structural Research Division, Materials Research Division, Environmental Research Division, and Research Administration Division. Each division works to solve social issues through technological development in civil engineering, building construction, environment, and disaster prevention, and implementing research outcomes.

  • Research and development related to reinforced concrete structures, steel structures, planning and management, and joint/contracted research.
  • Research and development on concrete and new materials, planning and management, and joint/contracted research.
  • Research and development related to marine and river environments, soil contamination, and urban environmental issues.

Director’s Message

“Without being satisfied with the status quo, we set higher development goals and contribute to realizing a sustainable society.”

Since its opening in 1993, our institute has focused on future-oriented research and development to meet the changing needs of society and customers, striving to create a rich and sustainable society.
Our main initiatives include technologies for disaster safety (earthquakes, typhoons, heavy rain), decarbonization efforts, productivity improvement technologies to address labor shortages, and innovative technologies that open new possibilities. We also collaborate actively with universities and institutions to advance wider and more specialized technological innovation.
In the 2025 Osaka–Kansai Expo, we jointly exhibited with Komatsu under the theme “Future Underwater Construction.”
The institute continues to take on challenges that contribute to a sustainable society while creating new values for the future.
