Dr.Tongchate Nakhata, Managing Director, CEDA

Standing on the cusp of a new era, we see industries have undergone radical changes in the last few decades. New technologies are transforming the face of business in every way possible. Engineering and Construction companies, being the pillar of a nation’s economic progress, have been struggling hard in exploring technologies to enhance productivity and work through a network of digital collaboration. CEDA, the Structural Consultants and Construction Management Company in Thailand, is a pioneer in the evolving landscape of the construction ecosystem. The company has made a strong impact in the world of E&C business by merging technology with the knowledge and practical capabilities of its contractors.

Founded in 1980 by Dr. Tawatchai Nakhata, an aficionado in building structural designing and Ph.D. in Earthquake Engineering, CEDA has taken an extraordinary leap in business, by combining advanced theoretical knowledge of contractors with their hands-on experience in the field. This alignment ensures that the structural designs meet both theoretical requirements and practical feasibility. Driven by Dr. Tawatchai’s exceptional skills and expertise in earthquake engineering, CEDA has been able to deliver effective and safe structural solutions for various building projects.

With the succor of a dedicated team of engineers and draftsmen, CEDA provides comprehensive structural consulting services. They assist clients in designing buildings that are structurally sound, resilient to seismic activity, and meet local building codes and regulations. CEDA’s services include structural analysis, design optimization, risk assessment, and construction supervision.

As the founder and leader of CEDA, Dr. Tawatchai Nakhata has been instrumental in the company’s success. His reputation and expertise in the field of earthquake engineering have earned him the trust of clients and the industry. This has led to increasingly sizable projects being entrusted to CEDA over the years. The company has established itself as a reputable firm in the field of structural engineering. Its commitment to excellence and its founder’s profound knowledge has contributed to its success in delivering topnotch-quality structural solutions for various building projects.


Turning over the pages of its initial journey, CEDA has been consistently marked by adaptability and growth. After its establishment in the 1980s, the company started with a small team comprising supporting engineers, draftsmen, and administrative staff. Dr. Tawatchai Nakhata served as the sole structural designer, utilizing his expertise in earthquake engineering.

Thanks to the trust and support of established architects and developers, CEDA gained significant opportunities to work on prominent building projects throughout the 1980s and 1990s. However, the 1997 Asian financial crisis had a crashing impact on the country and its businesses. Despite the challenging circumstances, CEDA adapted to the new economic landscape and managed to survive.

In 2005, Dr. Tongchate Nakhata assumed the role of managing director at CEDA. With his expertise in probabilistic structural engineering, Dr. Tongchate further developed the company with solid principles, building upon the strong foundation laid by Dr. Tawatchai. Under Dr. Tongchate’s leadership, CEDA expanded and emerged as one of the top structural consulting companies in Thailand.

Throughout its existence, CEDA has witnessed significant changes in the field of structural consulting. Hand calculations have been replaced by powerful software applications, and construction techniques, materials, technology, and design codes have rapidly evolved. CEDA not only adapted to these changing demands but also fully utilized the expanding technology to enhance its services.

Flagship services

During a glorious journey spanning over 40 years, CEDA has navigated the landscape to bring forth an extensive range of innovative and state-of-art solutions. The comprehensive structural consulting services are designed to cater to various aspects of building projects including:
