DMT steps strong into its 35th year by developing and implementing new solutions in operations to drive the “an alternative that values…your time”

The year 2024 has been a challenging one for the Company due to several factors, 1) The rapid evolution of technology and digitalization, 2) Changing consumer behaviors, 3) Climate change and new regulations arising from climate-related factors, and 4) Risks stemming from both domestic and international situations.
To manage and develop the organization sustainably, the management team has implemented several adjustments, including: 1) Enhancing operational and maintenance management systems by adopting international standards such as ISO 9001, ISO 14001, ISO 14064-1, ISO 45001, and ISO/IEC 27001 to improve work processes. 2) Strengthening corporate governance, with the Company receiving an "Excellent" (5-star) rating in corporate governance assessment. 3) Advancing ESG (Environmental, Social, and Governance) initiatives, leading to the Company achieving an AA rating in the SET ESG Rating for the year. 4) Conducting the Company's Carbon Footprint assessment to measure and reduce environmental impact. 5) Implementing Green Financing strategies, including securing Green Loans and Sustainability-Linked Loans to support environmentally sustainable projects. 6) Upgrading various technologies to improve management, service delivery, and cost control. 7) Developing human resources, particularly in technology utilization and AI adoption, to enhance efficiency and innovation and 8) Spinning off a specialized maintenance business, leveraging over 30 years of expertise in infrastructure maintenance by forming a joint venture with three Japanese partners—Hanshin Expressway Company Limited, KFC Company Limited, and AKROS Trading Company Limited—all of whom have extensive experience in expressway maintenance in Japan. These partners bring advanced technology and high-quality materials to the newly established A Siam Infra Co., Ltd. (A Siam), which began operations in April 2023. In 2024, A Siam successfully secured various civil maintenance projects, generating continuous revenue while expanding its expertise beyond expressway maintenance. This expansion strengthens the subsidiary’s ability to diversify into other civil infrastructure maintenance areas. Additionally, the knowledge gained from maintaining aging expressways and bridges, utilizing advanced technologies, and selecting durable, modern materials will further benefit the parent company.
As the CEO of Don Muang Tollway Public Company Limited, I would like to extend my sincere gratitude to the Board of Directors, executives, and all employees for their unwavering support and dedication in driving sustainable business operations. I also express my deep appreciation to all stakeholders for their trust and continued support. The Company remains committed to further enhancing and elevating its operations to achieve its long-term sustainability goals.
