Our advanced civil engineering and building capabilities are making a considerable mark in the history of construction at home and abroad. Such experiences and expertise are now providing the foundations for luxury lifestyles and industries all over the world.
Our business territories are now expanding into Asia, the Middle East, South America, and Africa.


Daewoo E&C changes and enriches lives by leading the construction of large-scale highways in South Korea. We are also world leaders in the use of tunnel construction to maximize efficient use of land. The Inje Tunnel of the Donghongcheon-Yangyang Highway won the “Civil Structure of the Year” award in recognition of its minimal environmental impact.
We have also carried out grand-scale overseas projects such as the world’s largest highway project undertaken by a single company in Pakistan, making us a global powerhouse in the highway construction sector.

The Environment

Daewoo E&C has consistently proven itself to be South Korea’s top performer in the innovative construction of water treatment facilities, including sewage treatment plants, water purification plants, and sewage pipelines. By developing new technologies such as Daewoo Nutrient Removal (DNR) sewage treatment system, we have taken the ground-breaking approach of moving all treatment facilities underground, creating parks aboveground and improving public amenities.
Daewoo E&C invests in innovative technology development that is leading the way in future energy generation and supply. We are also becoming a recognized leader in the green energy business.
