Work in Thorough Management of Occupational Health and Safety
The Taisei Group, in its “Action Guidelines for Taisei Personnel and the Taisei Group as a Whole,” emphasizes maintaining a safe and health working environment, and strive to prevent occupational accidents. Especially in construction activities, the Group commits to adhering to laws, regulations, internal standards, and safety plans. We prioritize ensuring the safety of construction personnel and give utmost importance to ensuring community safety, which includes preventing accidents that may affect third parties. This commitment is deeply ingrained, ensuring strict adherence by all the Group’s executives and employees.
Additionally, within the Group’s Medium-Term Business Plan (2021-2023), we underscore the aim to “achieve zero fatal accidents and zero serious accidents.” Our Safety and Health Policy designates the Occupational Health and Safety Management System (“TAISEI OHSMS”), executed in a systematic and organized manner, as the cornerstone of our safety and health management approach. Group executives, employees, and professional contractors collaboratively work towards these aims.
We are also pioneering the adoption and enhancement of safety management and monitoring systems leveraging ICT and AI technologies. In collaboration with professional contractors, we are establishing a safety and health management system that clearly defines “responsibility and authority.”
Our ultimate goal is to create a work environment where individuals feel secure and to be recognized as a company that earns the trust and empathy of the wider community.
Risks and Opportunities
The construction industry faces challenges, such as the aging of skilled workers, an influx of foreign labor, escalating natural disasters, and persistent severe heat. These challenges necessitate a higher level of commitment to occupational health and safety management. Inadequate attention to this critical aspect might lead to industrial mishaps, regulatory infringements, diminishing corporate value, and our reputation among our stakeholders.
Conversely, elevating our occupational health and safety standards, inclusive of our partners, aids in securing commendable partners and attracting top-tier talent. Innovative measures, like the automation of hazardous tasks and leveraging digital technologies, not only enhance safety standards but also fortify our Group’s productivity and competitive advantage.
For “Thorough Management of Occupational Health and Safety,” one of the materiality items, we have established “zero fatal accidents” as a KPI for FY 2023.
Moreover, in the Safety and Health Management Policy which is the basis of the “TAISEI OHSMS”, Taisei's occupational health and safety management system, the objectives for 2023 are “zero fatal accidents” “achievement of an frequency rate of less than 0.40” and “zero serious accidents.” The objectives of the Safety and Health Management Policy are reviewed each year, and based on the Safety and Health Policy that applies to employees and the personnel of subcontractors and suppliers who are contract workers, we work to ensure that all of the people involved in construction work harness their skills and passion to achieve these objectives.
- Between January and December 2022, there were 35 accidents at Taisei Corporation on a non-consolidated basis that required time off from work (as compared to 46 in 2021), resulting in an frequency rate of 0.31 (0.44 in 2021). There were zero fatal accidents. Compared to last year, total working hours increased by approximately 10%, but the number of accidents that required time off from work decreased, so the frequency rate improved.
An analysis of the accidents in 2022 reveals that the most common type of accident that required time off from work was “machinery-related,” followed by “falls.” We conduct a thorough investigation of the essential causes of the accidents that occur and initiate proper improvements and measures to prevent a reoccurrence, in order to eliminate similar accidents and disasters.
Moreover, to reduce risk, we conduct appropriate risk assessments based on the “TAISEI OHSMS”. Taisei's occupational health and safety management system, and also conduct a variety of workplace patrols and provide thorough safety education for employees, workers and other workplace personnel.
In FY2022, a total of 1,298 employees who work at construction sites participated in various safety training programs.

TAISEI OHSMS (Occupational Health and Safety Management System)
Based on the principle of “Safety First” as stated in its Safety and Health Policy, Taisei works with subcontractors and suppliers to operate its “TAISEI OHSMS*” occupational health and safety management system in a continuous and ongoing manner, with the objective of eliminating accidents and disasters, preventing accidents to third parties, and improving the health and safety level.
Taisei has established a Central Safety Committee (chaired by the Executive Vice President) made up of members appointed by the Management Committee. The Committee discusses safety management, the prevention of environmental accidents, and issues related to the health, safety and environmental management of subcontractors and suppliers, and reports and advices issues to the Management Committee. In addition, Branch Safety Committees, composed of branch supervisory health and safety managers, employees, and employee’s union, also meet regularly to hold discussions with employee’s union.
As one part of the Plan-Do-Check-Act (PDCA) cycle based on the “TAISEI OHSMS”, we conduct risk assessments (for example, when creating construction and health and safety plans after holding review meetings when a construction project has been acquired, and when advance reviews are conducted by the branch for plans concerning priority dangerous work operations). In addition, we also have the head office and branches conduct health and safety patrols at all sites where work is being done once construction starts, in order to check the implementation and operational status of health and safety plans and to conduct a risk assessment, and improvements and corrective action are conducted as needed in order to continually improve the level of health and safety.
Conceptual Diagram of TAISEI OHSMS (Occupational Health and Safety Management System)
* Our proprietary occupational health and safety management system developed in reference to the guidelines issued by the ILO and the Ministry of Health, Labour and Welfare. As November of fy2021, none of our business sites has obtained OHSAS 18001 certification.
Taisei Corporation implements risk management based on the “TAISEI OHSMS” occupational health and safety management system. Risk assessment is categorized as follows:
- Company-wide shared risk assessment, which is implemented comprehensively by the head office
- Branch office risk assessment, which is implemented at each branch office and
- Worksite risk assessment, which is implemented before work starts at each construction site.
These risk management initiatives are carried out at all existing and new worksites.
Moreover, for new worksites, branch offices make sure to thoroughly identify and mitigate risks as well as implement countermeasures during the construction plan review stage. By ensuring the implementation of risk assessment, dangerous and hazardous factors that may lead to accidents and disasters are eliminated or reduced, or necessary measures are taken to manage them as part of our efforts towards continuous enhancement of health and safety standards in conjunction with daily safety management PCDA cycles.
Construction Site Patrols
As one part of health and safety management based on the “TAISEI OHSMS” occupational health and safety management system, Taisei Corporation conducts patrols to confirm the safety and hygiene status at construction sites. In addition to patrols by Taisei employees at the head office and branch offices and patrols by the owners and safety personnel of subcontractors and suppliers and so on, the President himself visits and patrols construction sites during National Safety Week to make sure that each and every employee and worker shares the company's strong commitment to its “Safety First” policy. To ensure that each and every employee and worker shares the company's strong commitment to our “Safety First” policy, the President Aikawa himself visited and patrolled construction sites at the Tokyo, Kansai, Chubu, and Tohoku branches at National Safety Week FY2023. Following these patrols, the President provided instructions to business owners, contract workers, and company employees. He instructed them to conduct thorough safety management based on the situation at each construction site and to put together reliable safety processes. He then requested that employees, the Board of Managers, and the leaders of the workers, make a scrum to ensure thorough safety management. The construction site patrols by the President are conducted to impress upon all employees and subcontractors and suppliers the firm commitment to safety on the part of the company's top management.

Support for safety education of subcontractors and suppliers (cooperating companies)
By working closely with the Taisei Health, Safety and Environment Cooperation Association, comprising cooperative companies in Japan, we make efforts to prevent accidents and disasters. The members of the association participate in the Safety Conference held in January and Safety Promotion Conference in June every year. To prevent accidents and disasters, we utilize a bulletin, “Kyoryoku (Corporation)” and a list of disastrous cases for the education and guidance of safety and sanitation management.
Taisei has established several awards in an effort to improve the quality of health and safety, including the President's Commendation, the President's Award (safety and hygiene category), the President's Merit Award (Safety Order of Merit), and the Safety and Hygiene Environment Cooperative Federation Chairman's Award (Special Award). In addition, each year during National Safety Week (July 1 - 7), the Ministry of Health, Labor and Welfare presents the Minister of Health, Labor and Welfare Award to workplaces for excellence in workplace health and safety and persons of merit who have made a major contribution to the long-term improvement and development of safety and hygiene standards of a region, organization or relevant workplace. At Taisei Corporation, the Taisei/Rinkai Nissan/Honma Special Joint Venture Nagoya Central Stormwater Main Line Sewerage Construction Worksite received an award for excellence.
