In our second decade, we rapidly grew through diversification of expertise that addressed water and environmental management, urban and regional development, community-based development, infrastructure and transportation improvement as well as power and energy schemes. With interagency one-stop services, we helped clients to overcome challenges and accomplish major development projects in both Thailand and Association of Southeast Asian Nations (ASEAN) countries. We gradually prospered as one of the most heterogeneous providers of consulting services both domestically and regionally.

During the third decade, we extended our outreach to Cambodia, Lao PDR, and Myanmar. With a strong management foundation, we became recognized as the leading engineering consultant and related business service provider at national and international levels with track records in many Asian countries such as Cambodia, Lao PDR, Myanmar, Vietnam, Nepal, Sri Lanka, Timor-Leste, and Yemen.

We continue to grow steadily with a portfolio that numbers the successful achievement of more than 4,000 projects. Committed to providing high-quality and innovative engineering services, we have now expanded our expertise in the areas of transportation and logistics, water resources and hydropower, industrial and urban development, environmental management, and energy, in a bid to achieve the vision: A Regional Solution Provider and Innovative Business Developer.
