ABOUT QTCG

Our History

QTCG PLC. was established in 2001.  In over two decades, QTCG has comprehensively constructed and installed mechanical, electrical, and plumbing systems for more than 1,000 large-scale construction projects.  Our commitment to excellence has not only contributed to the success of our clients' ventures but has also been instrumental in driving the value of the Thai economy to over 12 billion baht.

With the vision of a founder, CEO Thitiwat Ngurnnumchokethanarat foresaw the potential and opportunities for business growth in engineering systems that grow in line with the advancement of technology and the exponential growth of the Thai industrial sector.  They gathered a team of professional engineers from multidisciplinary fields of engineering to establish
QTCG PLC. to facilitate complete systems engineering.  Afterward, the name was changed to "QTCG PLC."

QTCG PLC. is a partner in building a solid foundation and system for both the public and private sectors.  Today, QTCG PLC. is confident that we can effectively support the engineering systems for medium and large projects, ready to proudly step forward to be the leader in the systems engineering industry in ASEAN.

In the future, in addition to the development of knowledge, technology, innovation, and engineering skills, QTCG PLC. also aims to develop engineering services in response to the concept of energy conservation and environmental sustainability.  

For us, engineering is not just structural or system work, but a commitment to deliver a quality of life, economic potential, and sustainable environments.
