Promotion of Supply Chain Management
For the Taisei Group, subcontractors, suppliers, and other business partners play a pivotal role as essential business collaborators in addressing environmental, human rights, and other societal challenges. In our “Action Guidelines for Taisei Personnel and the Taisei Group as a Whole,” which emphasizes promoting partnerships with business associates, we are committed to forging fair and mutually trusting relationships. Aligned with our Declaration of Partnership Building announced in 2020, we aim to amplify value and champion mutual growth and harmony throughout the entire supply chain.
To be specific, we are advancing our sustainability initiatives based on the Taisei Group Sustainable Procurement Guidelines.
By enhancing the reach and understanding of these guidelines—hich outline collaborative efforts between the Group and business partners to solve societal sustainability issues through our business—e endeavor to further our sustainability goals.
Risks and Opportunities
Efforts towards addressing sustainability challenges must be advanced not only within the Group but also throughout the entire supply chain. If these endeavors fall short, there is a risk of adverse impacts on our stakeholders due to potential environmental degradation and human rights breaches within the supply chain. This could subsequently lead to diminished corporate value and our reputation among our stakeholders.
Conversely, initiatives aimed at resolving sustainability issues across the full supply chain help to achieve mutual growth and harmony with our business partners, further bolstering the Group’s productivity and competitive advantage.

Taisei Group of Companies Sustainable Procurement Guidlines
To contribute to resolve social issues through business activities, including issues relating to the environment and human rights, Taisei established the Taisei Group of Companies Sustainable Procurement Guidelines summarizing matters to be implemented jointly by the Taisei Group and its subcontractors and suppliers (established in 2014 as CSR Procurement Guidelines, and revised in April 2022 as the Taisei Group of Companies Sustainable Procurement Guidelines). Taisei works to ensure that all subcontractors and suppliers thoroughly understand the Guidelines and conduct sustainability activities in accordance with these Guidelines. Taisei also conducts training and online learning courses for subcontractors and suppliers relating to the Guidelines. We also ask business partners to provide training and guidance to their employees and work to ensure a thorough understanding of the Guidelines throughout the entire supply chain.
To ensure even greater awareness and compliance the Guidelines, beginning in FY2022 the essentials of the Guidelines have been included in contracts concluded with subcontractors and suppliers to seek their understanding and cooperation.
The content of the Guidelines is reviewed on an ongoing basis to ensure that it reflects global and societal trends relating to environmental and social issues.

Activities to Promote Sustainable Procurement
In September 2022, Taisei published the TAISEI Sustainability Handbook for training Group employees, and distributed it to all employees of Taisei and Group companies. The Handbook is designed to ensure a thorough awareness of the Fundamental Policy on Sustainable Development, its Human Rights Policy, the Taisei Group of Companies Sustainable Procurement Guidelines and so on. Taisei has also conducted briefings for individual departments and exchanges of views to ensure understanding.
Moreover, briefings on sustainable procurement are also held each year for the executives of the Taisei Corporation Procurement Division and the persons in charge of procurement at individual branch offices. In addition, online learning courses on the Taisei Group of Companies Sustainable Procurement Guidelines as well as global social issues in the supply chain relating to the environment, human rights, labor issues and so on are conducted available to all employees including those in the Procurement Division.
Briefings for Subcontractors and Suppliers by Chief of Branch
At the annual Safety Conference and other venues, each of the chiefs of all 12 branches in Japan explain the importance of sustainable procurement to subcontractors and suppliers and ask for their corporation in promoting activities at each company.
Supplier Support and Capacity-Building
The “Soyukai” is an organization of key subcontractors among the Taisei Corporation partner companies. Multiple councils have been established at the national Soyukai Federation as well as the branch Soyukai made up of members at individual branches. These councils meet regularly to hold exchanges of views between Taisei and member companies and to conduct training. These exchanges of views deal with social issues such as the need on the part of partner companies to secure leaders and successors, the need to improve benefits and so on, and the results are reflected in various measures. Moreover, Youth Management Study Groups made up of young managers who will be the leaders of next generation have been established as subsidiary organizations of the branch Soyukai. These study groups hold workshops and get-togethers and so on to improve the quality of the personnel who will serve as managers and top Soyukai officials.
In addition, sustainability training sessions for subcontractor and supplier owners have been held at the annual Safety Conference and other venues to provide training in social issues, including issues relating to the environment and human rights. Online learning courses relating to the Taisei Group of Companies Sustainable Procurement Guidelines are also offered to subcontractor and supplier employees.
In January 2024, we have issued the Taisei Group Supply Chain Sustainability Handbook, which provides a clear overview of our initiatives to solve sustainable issues such as human rights and environmental due diligence to subcontractors and suppliers.
Going forward, we will further accelerate the initiatives to realize a sustainable society by using this handbook to enhance subcontractors and suppliers' understanding and awareness of sustainable issues and promoting collective efforts across the entire supply chain.

Sustainability Activity Survey (Self-Assessment) for Subcontractors and Suppliers
Since FY2016, Taisei has conducted regular opinion survey by self-assessments to confirm the status of sustainability activities, including activities relating to the Taisei Group of Companies Sustainable Procurement Guidelines and their observance by subcontractors and suppliers. Beginning in FY2022, these assessments have been conducted annually.
Moreover, based on the results of self-assessment, TAISEI visits and audits companies whose status of activities relating to environmental, human rights, labor and other sustainability issues needs to be confirmed. On these occasions, exchanges of views are held with company owners and best practices are shared in order to effect improvements. Taisei is also working to improve the overall level and enhance activities throughout the entire supply chain, such as by asking subcontractors and suppliers to provide education and guidance for each of their business partners.

Survey of Foreign Technical Interns
Out of consideration for the possibility that foreign workers may be placed in a vulnerable position, the Taisei Group designates human rights problems relating to foreign workers as a priority issue for human rights due diligence, and works to prevent and reduce human rights risks pertaining to foreign workers. Particularly with regard to foreign technical interns, we work to foster an environment in which everyone is able to work with peace of mind, by establishing a procedure for accepting technical interns to ensure smooth acceptance at workplaces, and by conducting surveys of owners with regard to acceptance status and interviews with the interns themselves and so on. In the opinion survey conducted in FY2022, responses were received from 251 companies that have hired foreign technical interns. For 16 of the responding companies, Taisei checked the nature of the activities being conducted by responded documents, and as assessment feedback following the opinion survey, five companies were visited to conduct interviews on the status of activities as well as to exchange views with the owners, etc. To the degree that could be determined through the results of the surveys and interviews, no major human rights risks relating to the training were determined (improper collection of money or deduction from salary, non-payment of salary, or other negative impacts on human rights).

Response Regarding Sustainable Construction Equipment and Materials Procurement
Diverse raw materials including wood and stone are used in the construction industry. For raw materials whose place of origin is a developing country, there is increasing societal concern regarding illegal sourcing (cutting), oppression of native populations, forced labor and child labor and other legal and regulatory violations, environmental destruction, human rights violations and so on.
For this reason, in January 2019 Taisei conducted a questionnaire survey of its major material suppliers, in order to confirm their supply chains from raw material sourcing through delivery at worksites, and to determine whether there had been any legal and regulatory violations, human rights violations, or other violations by the overseas companies in these supply chains.
Based on the following survey results, in FY2019 as a follow-up survey we visited companies that submitted responses relating to lumber, stone and tile, as well as wholesalers and trading companies making up the supply chain, to explain our Procurement Policy and the Taisei Group CSR Guidelines (now the Taisei Group of Companies Sustainable Procurement Guidelines) and to require their understanding regarding sustainable procurement activities. At companies where interviews were conducted, we also held exchanges of views regarding the current status and future issues relating to traceability.
* Traceability: Releasing (making traceable) production histories and distribution channels
Overview of traceability survey (January 2019)
- Target companies: 43 major material suppliers dealing in lumber, stone, porcelain (tile), sand and aggregate (ready-mixed concrete), aluminum (joinery and hardware), steel (reinforcements and steel beams) and copper (wiring)
- Description: (1) Check of company names and addresses of trading companies, manufacturers, wholesalers etc. in the supply chain from extraction of raw material to delivery to construction site
(2) Check of legal violations by foreign companies in the supply chain as well as forced labor, child labor, long working hours, discrimination etc., consideration for employee health and safety, payment of appropriate wages, and infringements of the rights of indigenous people
- Survey results: (1) For 32 out of 43 companies (lumber, stone, sand and aggregate, steel), the supply chain back to the raw material extraction company was identified.
(2) There were no inappropriate cases of legal violations, etc. by foreign companies in the supply chain.
Survey of lumber procurement
In view of the importance of conserving forest resources and forest environments and ensuring sustainable procurement, from November 2022 through January 2023 a survey of lumber procurement by an opinion survey was conducted for subcontractors and suppliers dealing in major wooden products. Based on the results of the opinion survey, subcontractors and suppliers were visited and interviews regarding the status of activities and exchanges of views with owners, etc. were conducted.
The Taisei Group will continue to determine the status of lumber procurement and make improvements as needed in order to minimize the negative impact on forest resources and forest environments and achieve sustainable lumber procurement.
Survey of lumber procurement (November 2022 - January 2023)
- Target companies: 34 companies (companies dealing in wooden furniture, wooden joinery, wood finishing carpentry work, formwork construction and other major wood products having a trading volume above a certain level)
- Responding companies: 32 companies (percentage of companies surveyed on a contract amount basis, based on wooden product contract sums for contracts signed in FY2021: 69%)
- Description: 14 companies were visited and interviews regarding the status of activities and exchanges of views with owners, etc. were conducted.
As one part of supply chain management, when Taisei Corporation begins trading with new subcontractors and suppliers, it strives to familiarize the company with the Environmental Policy and Human Rights Policy of the Taisei Group as well as the Taisei Group of Companies Sustainable Procurement Guidelines, etc., and to confirm the status of efforts on the part of the new subcontractor or supplier relating to environmental issues, human rights and other social issues, health and safety, legal compliance, comprehensive efforts to prevent corruption and so on, by a self-assessment. If needed, interview surveys and exchanges of views are conducted in order to effect improvements.
The results for self-assessment were as follows:
4QFY2022 50 new subcontractors and suppliers
1QFY2023 85 new subcontractors and suppliers
Primarily through Production Process DX based on the key issue identified in the Medium-Term Business Plan, "To innovate production systems, and reform workstyles through digital transformation (DX)," Taisei Corporation works as one with our supply chain to improve aspects such as productivity, safety, and quality at construction worksites.
Information is shared at each stage, including design and construction, by utilizing BIM/CIM data linkage with subcontractors and suppliers as well as on-site management systems such as T-BasisX for construction projects and T-iDigital Field® for civil engineering projects. This has successfully reduced rework and menial tasks, in addition to shortening construction periods, and we have been promoting development of efficient, high-quality construction production systems.
Furthermore, we have also been promoting application of DX such as the Face Recognition Gate Management System and the Safety Documentation System, in our efforts for efficient labor management and safety documentation at worksites, as well as the cooperative operation control system T-iCraft® of the automatic construction machine for civil engineering projects T-iROBO® series.
Moreover, in our efforts beyond our DX initiatives, we are making efforts to improve productivity and safety with the supply chain by applying secondary concrete products (precast) for concrete construction, along with other measures.
