Safe and Healthy Work Environment

Safe Workplace

Policies and Systems

CTCI has established a HSE Policy as the overarching guiding principle for occupational health, safety, and environmental management. Under the "Safety First" priority, this policy applies to all operating locations, project sites, and merger & acquisition due diligence processes. It ensures that related risks are systematically identified, assessed, and controlled throughout every operational stage.

Beyond requiring all on-site personnel to strictly comply with safety protocols, there is an institutionalized mechanism in place that extend policy requirements to CTCI's suppliers and partners as a way of reinforcing shared compliance and accountability across the supply chain to foster a safe and healthy working environment. The policy, which is reviewed by the Board of Directors and signed by the Chairman, President, and heads of each business unit, clearly demonstrates the top management's commitment to HSE and environmental protection. The HSE issues are integrated into the core of corporate governance and sustainable development strategies to continuously enhance overall risk management and HSE performance.

CTCI remains committed to aligning with international standards by maintaining ISO 14001 and ISO 45001 management system certifications. The scope covers the Headquarters (Buildings I and II) of CTCI Corporation and all project sites, achieving 100% certification coverage. Furthermore, in compliance with the Taiwan Occupational Safety and Health Management Regulations, CTCI has established the Taiwan Occupational Safety and Health Management System (CNS 45001) and obtained TOSHMS verification. To ensure robust governance, an Occupational Safety and Health Committee has been established by law to convene regular meetings to discuss safety and health-related issues. Additionally, an HSE Management Review Meeting is held annually, with senior management participating to evaluate the effectiveness of the HSE management system and safety performance. Through systematic review and continuous improvement mechanisms, CTCI ensures the effective operation and ongoing advancement of its management systems.
 

CTCI's safety and health-risk assessment follows the provisions of ISO 45001: 2018, where action plans for risks deemed moderate or above are developed to eliminate hazard and minimize risk. When corrective and preventive measures are proposed by the project team, a reassessment of hazard identification and risks is mandatory. In the process of reviewing organizational background, CTCI assesses risks and opportunities associated with internal and external factors, and develops corresponding strategies and action plans in all aspects including management system, compliance obligations, risk-management procedures, external communication, office operating environment and resources, health management, operations, and operational controls. CTCI stipulates in its HSE Guidelines that "when an immediate danger is encountered in the course of conducting business, one may stop working and retreat to a safe location without jeopardizing the safety of other workers." The Guidelines has also laid down reporting procedures related to occupational hazards and dangers, allowing workers to report events at once to the immediate supervisor to reduce risk impact. The risk assessment personnel have received the corporate training on internal risk assessment management procedure prior to implementing risk assessment.
 

To minimize risks of incidents and the potential damage, CTCI has established a standard procedure for incident investigation. When an incident occurs, the incident is first assessed in terms of severity level, and a corresponding seniority of personnel is assigned to investigate the matter within a given timeframe. Improvement measures are adopted based on the investigation results, followed by the issuance of case studies (Lessons Learned) for future guidance, and all site personnel are required to improve training for employees and contractors. Feedback from engineering design, procurement, and construction units is collected to assess systemic risk. Policies and procedures are then improved to prevent future occurrence.
 

 
CTCI proactively implements HSE management by conducting rigorous reviews and improvements after every on-site incident to prevent recurrence. To enhance oversight effectiveness, the department heads would conduct audits on weekdays and weekends. In 2025, 154 audits were carried out. An identified deficiency must be rectified within three days. Every quarter, a review meeting will take place, with business unit heads attending, to examine the audit results and ensure on-site safety measures have been strictly implemented. To strengthen senior management oversight, a "Monthly Safety Performance and Improvement Tracking" report has been submitted to the President since 2025. This report includes details on management actions for high-risk critical tasks and specialized operations, which helps verify management effectiveness across all projects.

In response to the occupational incident of fall from height in 2025, the company strengthened its source control at the construction site, and included additional inspection items for lifeline anchor points in the safety lifeline checklist. Furthermore, refresher training was provided to the steel structure subcontractors. Aerial work platforms and ground prefabrication methods were adopted with priority to reduce the frequency of high altitude work and the risk of falling. Additionally, to reduce the hazards arising from high risk operations such as fall from height, collapse of stacked materials, falling objects, and electric shock, CTCI has included the scaffolding specifications and safety requirements in the contract clauses, and required scaffolding contractors to assign qualified supervisors to conduct site supervision, thereby ensuring the compliance of provisions on the assembly, use, and removal of construction scaffolds. Meanwhile, CTCI has reinforced the material storage management requirements, including stable stacking of materials, effective binding and setting of guard rails, and stacking height of no more than 1.8 meters as well as requirement for use of tool bags and tool lanyards by operators to avoid the falling of tools or materials; furthermore, the company has revised and clarified construction procedures for power cutoff and work near live electrical equipment, as well as strengthened the control of the electric room to ensure the operators' electrical safety.

With respect to the management system, CTCI strengthened the procedures for the application and inspection of work permits to effectively control high-risk operations. Besides, management personnel (supervisors and HSE personnel) are required to immediately rectify unsafe behaviors during site commanding and supervision. Besides, CTCI has established a "Stop Work Authority Procedure" to foster an HSE culture where all personnel are entitled to suspend and stop unsafe conditions. Management-level analyses on previous occupational incidents were also conducted to improve the necessary check items on the automatic checklist.

To narrow the safety awareness gap arising from insufficient work experience among site workers and eliminate inconsistent understanding of safety requirements among multinational workers, the company has developed an "HSE Technical Bulletin," a form of communication that blends in the corporate standard operating procedures and best-practices from construction sites. Through illustration, the bulletin helps clarify all types of high-risk operations and indicate the common deficiencies, as well as the key points for operation and precaution. It is presented in three languages, i.e., Chinese, English and Thai, so all colleagues (including foreign workers) clearly understand and implement the foregoing, thus further improving the effectiveness of overall construction site safety management.
 

In support for the World Day for Safety and Health at Work on April 28, CTCI took part in the "Smart Harbor City Sustainable Happiness Forum and Exhibition" held by the Kaohsiung City Government on April 27, 2025 and set up a display zone called "Construction Scaffold Observation and CTCI Digital Twin Innovation," where the company exhibited scaffolding safety facilities, technological innovation progress related to the digital twin, and anti-falling demonstrations. During the event, the President of CTCI accompanied the general public and children to experience full body harness wearing procedures and scaffold walking operations. The company helped the government agencies to increase the public's awareness on occupational health and safety, strengthen their safety awareness. This is putting the concept of "making safety visible" into practice. By offering hands-on experience, CTCI has helped elevate the safety concept from awareness to implementation.

With the rising number of Thai migrant workers, CTCI has organized safety awareness enhancement activities for Thai migrant workers to prevent rising operational risks due to their unfamiliarity with Taiwan's local occupational safety and health regulations and construction site management systems―a result of language barriers and cultural differences. Professional Thai HSE engineers are invited to provide training on the improvement of Thai migrant workers' safety awareness, and clarify safety guidelines for lifting operations, high-altitude operations, electrical work, hot work, and material storage, to ensure that safety information is clearly and correctly delivered to migrant workers in their native language. CTCI maintains bilateral communication and encourages Thai migrant workers to actively participate and raise questions, thereby improving their participation and strengthening their understanding and recognition of construction site safety specifications. In the end, the activity improved their overall safety awareness and demonstrated CTCI's care and respect for Thai migrant workers.

Additionally, CTCI distributed safety handbook written in Thai to Thai migrant workers and asked them to carry at all times. The handbook included information on personal protective equipment, life-saving safety rules, and crucial instructions for material stacking, lifting operations, high-altitude operations, and electrical work. A glossary of common construction site terms in three languages―Chinese, English, and Thai― is included in the handbook to help Thai migrant workers communicate with local workers, thereby fostering site safety management and crosscultural teamwork.

CTCI has established a formal consultation and participation mechanism to enhance employee engagement in HSE management. Each department nominates a non-managerial representative with at least two years of experience to serve as a bridge between employees and management, ensuring the HSE system aligns with collective needs. To foster communication, CTCI conducts quarterly reward-based BBS surveys across the First Headquarters to gather feedback on topics such as emergency evacuation routes, general on-the-job training regulations, and other HSE promotion information. Specific improvements are then made based on the colleagues' suggestions, such as office energysaving measures and enhancements to office environment safety. Results are reported to the quarterly Occupational Safety and Health Committee and disclosed to all employees through official announcements.

Heat hazard prevention

As climate change intensifies, summer temperatures have continued to rise in recent years. Since construction site operations are carried out outdoors under strong sunlight, CTCI requires staff to follow "Heat Hazard Prevention and Management Measures" to effectively protect workers from heat illnesses and ensure their health and operational safety.
 

Construction Safety and Quality

Since near-miss incidents are critical leading indicators of potential risks, CTCI utilizes its internal HSE Information Management System to manage reporting and corrective actions across all project sites. In 2025, 49 near-miss incidents were recorded. For significant cases, the HSE Department, construction personnel, and contractors have convened review meetings to develop concrete improvements and Lessons Learned. These insights were integrated into site Toolbox Meeting to enhance hazard prevention awareness.

To further reduce unsafe behaviors, CTCI has implemented a Project Behavior-Based Safety (BBS) system, placing behavior observation at the core of preventive risk control. CTCI has also introduced the "BBS Observation" App at all project sites, providing frontline workers― including contractors―with a digital tool to report risks in real-time. This digital integration helps enhance data consolidation and management efficiency.

On-site HSE personnel compile weekly observation data to analyze trends in unsafe behaviors, which serves as the basis for strengthening safety management across different work disciplines. Furthermore, project sites hold regular BBS review meetings to track high-risk items, forming an "Observation– Analysis–Improvement–Tracking" management loop to continuously foster a robust safety culture.
 

Total HSE Culture

CTCI recognizes that to achieve the goal of "Safety First," all employees need to make a collective effort. Establishing an HSE culture is a longterm, comprehensive transformation encompassing values, attitudes, behaviors, and institutional systems. Therefore, CTCI actively invests resources to promote company-wide participation in HSE activities. By continuously reinforcing safety awareness, CTCI aims to internalize HSE principles into daily operations, progressively shaping a robust corporate safety culture.
 

To increase HSE awareness, CTCI conducts Total HSE Evaluation annually. The HSE Department designs training materials and assessment modules that cover corporate HSE policies, core concepts, and current issues. This study-and-test mechanism allows non-HSE personnel, managers at all levels, and project teams to acquire essential safety knowledge and attitudes, thereby fostering a corporate safety culture. Evaluation results are analyzed during HSE Management Review Meetings to serve as a basis for future training planning and key promotional campaigns. This systematic approach ensures the continuous optimization of HSE management and enhances the overall safety competency of our employees.
 

To cultivate a deeper safety culture, CTCI systematically promotes Group-wide HSE activities annually, extending HSE principles from regulatory compliance to the organizational culture. In addition to supporting the "National Workplace Health and Safety Week" held by Occupational Safety and Heath Administration, CTCI designs diverse and engaging activities to internalize safety awareness into daily operations and employee behavior, strengthening risk awareness and self-management capabilities. CTCI's HSE initiatives in 2025 featured a wide range of measures, including open letters from senior executives, construction site/ plant promotions, HSE Slogan Contest, group HSE annual meetings, and themed speeches. These efforts significantly elevated employee awareness and reinforced "Safety First" as a core professional value.

Furthermore, CTCI has integrated "Safety First" into its annual performance appraisal mechanism, linking safety performance with individual and organizational evaluations. By formalizing safety responsibilities at all levels, the company ensures that safety values are effectively translated into concrete actions, further embedding them into the daily work of every employee.
 

To deeply cultivate the safety culture, CTCI held the Group HSE activities, in response to the National Workplace Safety and Health Week campaign organized by OSHA. Through the soft appeal of the HSE activities, CTCI seeks to exemplify behaviors consistent with corporate culture and to deepen employees' safety awareness. In 2024, CTCI launched a series of group HSE activities, including open letters from senior executives, construction site/plant promotions, HSE fun contests, Group HSE annual meetings, and themed speeches, to raise employees' HSE awareness and recognition and makes it clear that "safety first" is one of the vital conditions for achieving professionalism. Additionally, CTCI has included "safety first" in the criteria in the year-end performance review, reflecting its strong commitment to the value of safety and ensuring that a safety-oriented culture is deeply embedded in every employee’s daily work and actions.
 

CTCI Group HSE Series Activities in 2025

To minimize occupational incidents, all employees and contractors are required to undergo jobspecific safety and health education and incident prevention training before working at project sites, in accordance with local regulations or client requirements. This reinforces personnel awareness of HSE regulations and operational standards. Mandatory training includes no less than three hours of "General Occupational Safety and Health Training." For those engaged in special operations as defined by law, an additional three hours of training are required, with at least three hours of HSE on-the-job retraining every three years. For employees who work at the Headquarters, CTCI conducts regular HSE training as required by law, including fire drills, new employee orientation, general on-the-job safety training, first-aid training, health promotion, and specialized high-risk hazard training.

Regarding project sites, CTCI continues to refine its training management mechanisms. All sites are required to identify training needs based on factors such as operational risks and job categories and to establish a Training Matrix, which is to ensure appropriate training for all site personnel. In 2019, the Ministry of Labor introduced the "Taiwan Occupational Safety Card," a certification program with 6-hour general HSE course and examination to enhance construction workers' knowledge on safety and incident prevention. This ensures workplace safety and reduces repetitive training. As an authorized training provider for the "Taiwan Occupational Safety Card," CTCI continues to organize training sessions across project sites, actively encouraging employees and contractors to obtain the certification. In 2025, CTCI's domestic project sites conducted 75 Occupational Safety Card training sessions, attended by 1,371 participants that include CTCI employees, subcontractors, and migrant workers.
 

CTCI's commitment to HSE is tangibly demonstrated through its operational management and project execution results. Notably, the First Headquarters has maintained an ongoing record of safe man-hours since January 2007, reaching a cumulative 72,530,162 hours as of December 31, 2025―a testament to CTCI's robust safety management.

Regarding engineering projects, achieving safe man-hours remains a primary management goal. Among 14 large-scale projects under construction in 2025 (with a contract value of more than NT$6 billion), 7 projects exceeded more than 1 million safe-man-hours, with Qatar RLPP project exceeding 10 million. This reflects CTCI's capability to maintain excellent safety performance even in high-risk environments. The safe man-hours for the remaining projects continue to accumulate as construction progresses, steadily advancing toward established safety targets through CTCI's systematic management mechanisms.
 

To encourage the implementation of the HSE management mechanism at the worksite, and the enhancement of project safety performance, CTCI has developed an incentive system offering special project rewards for completed projects that exceed certain number of safe work hours. In addition, CTCI conducts "Project Site and Personnel Selection with HSE Excellence" every year, where projects, on-site supervisors, and safety personnel with excellent HSE performance are rewarded and praised as role models. CTCI's HSE management effectiveness can also be seen in the accolades it receives from government agencies and customers, such as various awards and certificates of appreciation issued by the Taiwan OSHA, Taipower, and foreign clients. Below are the results that demonstrate CTCI's effort in HSE management and execution effectiveness.
 

2025 HSE Awards

Contractor Management

CTCI collaborates with subcontractors to build a safe and healthy workplace. To ensure compliance with HSE regulations and internal standards, CTCI enforces the "Construction Subcontractor HSE Management Rules." These requirements are clearly defined during procurement and bidding, serving as the foundation for contract management and project execution.

Since CTCI's global clients care about the HSE performance of CTCI's subcontractors, CTCI has implemented the "HSE Subcontractor Evaluation Module." This module accounts for 20% of the evaluation mechanism for project suppliers and contractors. The mechanism converts the HSE performance of contractors into a unified evaluation benchmark for quantification. Contract amount, accumulated construction hours, among other criteria, serve as screening criteria for constructor evaluation. The evaluation uses a 10-point scoring system; those scoring below 5 points will be designated a status for enhanced HSE protection and monitoring. In 2025, 267 contractors were selected for evaluation, and the evaluation completion rate reached 100%. The evaluation results are fed back to the company's subcontractor performance evaluation sheet and serve as a reference for CTCI's procurement and contractor selection decision.

To enhance management efficiency, CTCI leverages digital innovation. Its in-house developed app and information systems have streamlined data consolidation and enabled real-time feedback, allowing for faster detection of high-risk hazards and reinforcing safety awareness among the workforce.
 

Healthy Workplace

Comprehensive health management

CTCI is dedicated to protecting employee health by creating a safe, healthy, and efficient work environment through three core pillars: health examinations, health protection, and risk management. By integrating and continuously improving these areas, we enhance employee wellbeing and corporate competitiveness, achieving a win-win for both labor and
management. Exceeding regulatory requirements, CTCI employs eight fulltime nurses, three contracted labor health physicians, and two contracted physical therapists. In 2025, nearly NT$7.22 million was invested in employee physical and mental health. In addition to health seminars, fitness assessments, and group walking events, the company manages highrisk groups with specific health and working hour recommendations, while providing advanced screenings and cancer tests for early detection and treatment.
 

Highlight 1 ｜ Building an Age-Friendly Harmonious Workplace

Taking into consideration of its employees' health follow-up status over the years and the characteristics of the industry CTCI belongs to, CTCI Group has significantly adjusted the subsidy amount for health checkups per age groups since 2024. With the arrival of an aging society, the proportion of employees re-employed after retirement has increased every year. In 2025, the Group further raised the health checkup subsidy for employees aged 60-65 again from NT$3,000/year to NT$4,500/year, and offered them diverse health checkup options. Furthermore, the care extends into employees' retirement. Four health checkup hospitals are designated to provide retired employees with the same value health checkup packages as the current employees. As a result, employees of CTCI Group still enjoy health checkups without health gaps after retirement.
 

Highlight 2 ｜ Employee Physical Fitness Testing

Regular exercise can enhance personal physical fitness. To accurately understand whether a person's physical fitness is improved, proper test items and methods are necessary to truly assess the level of improvement of physical fitness and the effectiveness of the excercises. For two consecutive years since 2024, CTCI Group cooperated with the Department of Physical Education at Fu Jen Catholic University and the Wugu Civil Sports Center to hold physical fitness testing. The four elements of employees' healthy physical fitness―cardiorespiratory endurance, muscular strength and endurance, body composition, and flexibility were reviewed through heart rate tests by doing progressive high knees in place, left- and righthand grip strength test, back-protected sit-and-reach flexibility test, and InBody body composition analysis. A total of 243 employees participated in the testing, with 67% female and 34% male. Among them, 58.1% had regular exercise habits (3 times a week, 30 minutes per time, lasting for more than 3 months). The overall satisfaction with this activity reached 98%. The test results showed that the grip strength was negatively related to age, with grip strength gradually declining as the age increases; female employees' flexibility was better than that of males.
 

Highlight 3 ｜ Group Walking Campaign!

In support for the "10,000 Steps a Day for Health Protection" activity launched by the National Health Administration in 2002 as well as the designation of November 11 as "National Waking Day," CTCI initiated a three-month Group Walking Campaign in 2025. Through the online walking campaign, employees were able to incorporate walking into daily routines using fragmented spare time amidst their busy work, helping them develop consistent walking habits and fostering an active sports atmosphere within the company.

In 2025, 810 individual participants and 78 teams with 287 employees joined the Group Walking Campaign, accumulating 562,616,869 steps in total, or 15,083,758Kcal, and reached an accumulated distance of 393,831.808km (equivalent to the distance circling Taiwan for 358 times).

Since the walking campaign was unrestricted by space and time, the satisfaction rate regarding the participation of construction site employees reached 99% compared with previous months, and the company received many positive feedbacks and improvement suggestions.
 

CTCI has established Employee Welfare Committee in charge of promoting employee welfare. Budget mainly derives from corporate funding and comprises four categories: general welfare, leisure, educational support, and others. Those who enjoy employee benefits include regular, contract employees and dispatched employees. Total expenditure of employee benefits in 2023 amounted to NT$65,861,114. In addition to members elected from each department, Employee Welfare Committee has an office staffed with two administrators to provide services and consultation.
　

Health Risk Identification and Measures

Health risk matrix: This matrix, which looks at the incidence and impact of injuries and illnesses, is used to identify health risks of CTCI employees and to formulate health management and mitigation measures.
 

Risk Management and Health Promotion Activities

Healthcare

CTCI proactively establishes a sound and healthy work environment, while promoting measures to enhance the overall health conditions in the workplace. In 2025, the company continued to obtain certified qualifications such as healthy workplace, reassuring workplace with AEDs, and quality lactation room. With respect to the psychological care for its employees, CTCI offers care assistance, employee suggestion processing (e.g., proposal improvement, employee complaints, unlawful infringements, sexual harassment, and whistleblowing), labor dispute handling, and risk assessment of working conditions (e.g., risk assessment on extended working hours, etc.). CTCI has also cooperated with external institutions to assign professional counseling psychologists to provide psychological counseling services. In 2025, 450 people received psychological counseling. The Employee Assistance Program (EAP) was entrusted to an external institution, which assisted employees resolve their psychological distress.
 

Employee Welfare Committee

In order to provide employees with better welfare protection, CTCI established the Employee Welfare Committee, offering four main categories of benefits: welfare subsidies, leisure and recreation, educational incentives, and other welfare benefits. The beneficiaries of employee welfare include formal employees, contract employees, and dispatched workers. In 2025, employee welfare expenditure reached record high at NT$147,826,777, demonstrating the company's emphasis and commitment to employee well-being. To ensure the effective implementation of welfare measures, the Welfare Committee not only includes committee members who are elected by departments to participate in decision-making, but has also set up a dedicated office staffed with two administrative personnel, providing more comprehensive services and consultation channels to ensure that every employee receives timely and thoughtful assistance.
 

Diverse Development of Corporate Clubs

CTCI encourages the development of corporate clubs, which are diverse channels for employee relaxation and interaction. As of 2025, there are 16 active corporate clubs. As epidemic prevention restrictions were lifted, lectures, courses, and outdoor activities flourished to create a learning and sharing atmosphere. Corporate club expenses are covered by the annual budget of the Joint Employee Welfare Committee and can apply for additional subsidies in accordance with the Association Management Measures. Activities that align with the United Nations Sustainable Development Goals (SDGs) can receive an additional 10% subsidy on event expenses upon approval, encouraging employees to initiate and participate in sustainable actions.
