Civil Engineering

Developing safe and secure infrastructure through advanced technologies

We build infrastructure essential to people's lives, such as tunnels, bridges, dams, riverbanks, railroads, and expressways. In doing so, we contribute to making an abundant society and ensuring safety and security for everyone.

Recently, this business domain has widened to cover maintenance and upgrades, including repairs, and we have been actively involved in extending the life and functionality of existing infrastructure. We have also been leveraging cutting edge ICT such as 3D measurement data and unmanned construction machinery to make steady improvements in construction work quality and productivity.

Business Policy

  • Strategically acquire orders to construct, renew, and extend the life of infrastructure that contributes to the safety and security of the public as well as Japan's economic development.
  • Work to acquire orders for energy-related projects that respond to social and environmental change.
  • Expand design-build projects using labor-saving technology and ICT, and further increase productivity and construction safety using IoT and AI.
  • Diversify earnings base by expanding into upstream and downstream sectors in the civil engineering business.
  • Secure engineers and skilled workers by improving the work environment on construction sites and secure production capacity by supporting their development and so forth.

Business Environment

  • Domestic construction investment to be around ¥50 trillion in the fiscal year ending March 31, 2018, basically on par with the previous fiscal year.
  • Urgent need for repair and renovation of infrastructure constructed during Japan's high growth period.
  • Ongoing strong investment related to the Tokyo 2020 Olympic and Paralympic Games and the Chuo Shinkansen Project using the Superconducting Maglev System.
  • Diversification of the types of orders due to the introduction of an array of bidding contract systems.
  • Risk of production capacity shortages from a decline in skilled workers due to demographic structure.
  • Increased social requirements for correction of long working hours.

Business Strategies

We aim to receive orders strategically from projects in our areas of strength, which include advanced technologies such as new infrastructure construction, infrastructure renovation, disaster prevention and mitigation measures, and energy-related fields.

In the currently favorable order environment, we aim to expand orders while ensuring high quality. We will thus work to improve productivity by making greater use of ICT and labor-saving technologies such as precasting. At the same time, we will promote the development of unmanned construction techniques for safer construction sites.

We will also aggressively expand into upstream and downstream sectors in the civil engineering business to help strengthen our sales capabilities and bolster our competitiveness by swiftly grasping and attentively addressing customers' needs, while striving to diversify our earnings base.

As a part of work style reform, we will promote a system of eight vacation days per four weeks at all construction sites. In addition, we will coordinate with suppliers on sharing issues and solutions, targeting higher productivity so that we can shorten total working hours and keep skilled workers' wages at appropriate levels. By taking such initiatives, we will realize a comfortable work environment that will contribute to securing construction industry workers.
