Our Vision
Though we are proud on our long >45 years of experiences, we are aware that we should foresee as multiple perspectives and always exploring advanced and practical future technologies. Building construction is no longer based on 4 basic elements but evolved with another, the 5th element.
Green & Sustainable Concepts
Today, continuing that vision, the spirit within us continues on with “Green and Sustainable” design concept A lot of EEC post references well demonstrate our practice in energy efficiency, environmental and safety design.
Happiness is proven by the long term staff
EEC is a family, brothers and sisters like society. We value seniority and many staff lives in EEC for more than 20 years. We emphasize staff engagement and as well offer career development.
