Improving Health and Safety Standards

Policy and Management

Taisei Corporation's safety-first policy is expressly stated in the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole that “We strive to maintain a safe and hygienic work environment and prevent occupational accidents.”
The important issues relating to sustainability in the Medium-term Business Plan include “achieving zero fatal accidents and zero serious accidents.”
In FY2020, we have also specified key issues and expressly stated in the Health and Safety Policy that we will strive to achieve zero fatal accidents and eliminate all accidents and disasters. To this end, the entire Group --including Taisei Corporation employees, Group companies, and partners --is working together to promote initiatives to give shape to day-to-day safety practices.
Moreover, we have identified "Thorough Management of Occupational Health and Safety" as a part of Materiality (Important Tasks for the Taisei Group), and this has been established as a principal policy in the Group Medium-term Business Plan (2021-2023). In addition, we have established "Number of fatal accidents 0" as a KPI objective for FY 2023.
In addition, we have established the Central Safety Committee where safety management, prevention of environmental accidents, as well as issues related to the safety, health, and environment of specialized contractors are discussed and reported to the President. A Branch Safety Committee, composed of branch supervisory health and safety managers, employees, and labor unions, is also held to communicate with labor unions periodically.
In close cooperation with the Taisei Corporation Safety, Health, and Environment Cooperation Association, which is organized by our cooperating companies across the country, we hold the “Thoroughgoing Safety Convention” and “Safety Promotion Convention” to prevent accidents and injuries.

Promotion Framework


Based on our occupational health and safety management system “TAISEI OHSMS*,” we properly implement and operate the PDCA (plan-do-check-act) cycle, and we conduct risk assessments (e.g., particularly when creating construction safety and health plans and participating in Accident Prevention Council meetings after holding review meetings when acquiring a construction project) and take necessary measures based on the results (e.g., have the head office and branches conduct health and safety patrols at all sites where work is being done once construction starts) to mitigate residual risks in the workplace. When a serious accident occurs, a disaster analysis will be conducted and the accident information will be horizontally shared over the intranet and other media to prevent recurrence. We also provide safety education for those concerned at construction sites to make sure workers comply with safety rules.

* 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.

Safety Performance

KPIs Number of fatal accidents 0

Taisei's safety record in 2020 comprised 35 incidents that required time off from work (down from 74 in the previous year), 30 incidents that required four or more days off from work (down from 60 in the previous year), and an incident frequency rate of 0.35 (see figure below). An analysis of the incidents in 2020 reveals that situations in which employees became trapped by or caught in machinery were the most common, followed by falls. In 2021, we will continue to conduct workplace patrols, implement employee and worker safety training and promote various other policies to achieve thorough health and safety management based on the Taisei Occupational Health and Safety Management System (OHSMS).

Construction site patrol

At Taisei Corporation, we conduct patrols to confirm the status of health and safety management at construction sites. Besides the patrolling by our employees and the safety staff of cooperating companies, the President himself visits and patrols the construction sites during the National Safety Week to make sure the top management's strong commitment to the “safety first policy” is thoroughly shared with each and every one of the employees and workers.

Support for safety education of specialized contractors (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.

Employee safety education

We provide employee training to deepen their understanding on accident and disaster prevention, improvement of health and safety awareness, and laws and regulations related to safety. Education is provided based on the job level of the employees according to year of enrollment and job functions to provide basic knowledge necessary for their job roles. A monthly Accident and Disaster Report is distributed on the intranet to share information including accident case reports, the results of casualty analyses, and relevant preventive measures.

The number of participants in FY2020 was as follows.


Type of education Applicable participants Actual number of participants 
New employee introductory training (at time of hire) New employees 351
Basic safety training Employees hired 2 - 3 years ago 317
Practical safety training Employees hired 4 - 5 years ago 95
Supervisor training Employees hired 6 - 7 years ago  215
Administrator, supervisor and former manager training Employees hired 8 - 10 years ago  85
Total   1,063


We have established several award systems including the President's Award granted to business sites, specialized ontractors, foremen's associations and Group companies, as well as worksites that have won the Ministry of Health, Labour and Welfare Award for excellence in workplace health and safety.
Awards were granted to encourage improving the quality of health and safety, including the President's Award, which was granted in FY2020 to two worksites for excellence in workplace health and safety.

Cultivation of Technical Staff and Securing Human Resources

The construction industry has an industrial structure with a large number of elderly workers compared to other industries, and the massive retirement of elderly workers is expected in the near future. Therefore, securing workers to support the construction industry in the future is an urgent issue.
At Taisei Corporation, we are focusing on the dissemination and promotion of the Construction Career Up System (CCUS), which enables us to objectively and continuously accumulate and confirm the experience and skills of each and every construction engineer, which has been difficult to objectively grasp and visualize in the past, through cross-industrial, unified rules.

Dissemination and Promotion of CCUS

KPIs Construction Career Up System Worksite registration rate 100%

We established the CCUS Promotion Roadmap (fiscal 2021–2023) in June 2021. In accordance with the new target of the Nikkenren, we have determined to achieve 100% for three indicators, namely the service provider registration rate, skilled worker registration rate and working history accumulation rate, by the end of fiscal 2023, and have set annual targets to achieve it. We will continue promoting CCUS and encourage our cooperating companies (suppliers) to register more service providers and skilled workers.

Construction Career Up System (CCUS):

An initiative to enhance the coordination with cooperating companies and their organizations to visualize and share skills, experience, qualifications, and the status of enrollment in social insurance programs, etc., of each of the skilled construction workers under uniform rules of the industry.

Securing and Fostering Skilled Construction Workers

Taisei Corporation promotes the improvement of the working conditions of skilled construction workers by requesting partner companies to submit quotations and other documents that expressly state the appropriate labor cost (labor wage) that is in accordance with the purpose of improving the labor wages of skilled construction workers and by also respecting such documents, based on the Statement for Respecting Fair Labor Cost Estimation released by Japan Federation of Construction Contractors.

Establishment of Various Foremen Systems

Taisei Corporation has introduced certification systems (System for reward to excellent civil engineering skilled workers, systems for first-class foremen and highest quality foremen in building construction), in order to promote “securing and developing skilled construction workers who will support the industry in the future” and “improving their working conditions”.
In the civil engineering field, the system for rewards for excellent civil engineering skilled workers, under which a reward is paid to the workers with excellent construction skills who contribute to construction work at the sites of Taisei Corporation, is introduced to improve the overall capabilities, including quality, safety and skills.
In the building construction field, a system for the highest quality foremen was newly established and has been put into operation upon partial revision of the first-class foremen system during FY2015 to further improve the foremen's construction management capability, including quality, skills and safety to strengthen the production system.
