DAEWOO E&C

Highways

As the main arteries connecting major cities and facilities, highways are strong contributors to economic development. Daewoo E&C changes and enriches lives by leading the construction of large-scale highways in South Korea.

Daewoo E&C has participated in the construction of major highways in South Korea since 1978, beginning with the Busan-Masan Highway, Section 3, which was also notable for its reduction of logistics expenses. In addition to national projects, we have built the Cheonan-Nonsan, Daegu-Busan, Yongin-Seoul Highways as well as other privately-financed roads, contributing to the invigoration of regional economies and the balanced development of land.
We are also world leaders in the use of tunnel construction to maximize the efficiency of land. The Inje Tunnel of the Donghongcheon-Yangyang Highway is the longest such facility in South Korea and provides the fastest connection between the Metropolitan Area with the east coast. It was completed in 2017, and won the ‘Civil Structure of the Year’ award in recognition for its minimal environmental impact. We have also carried out grand-scale overseas projects such as the world’s largest-ever highway project undertaken by a single company in Pakistan, making us a global powerhouse in the highway sector.

Roads & Bridges

Roads and bridges are invaluable facilities that allow for movement and connection of human and material resources.
Daewoo E&C is committed to applying our advanced technology to build convenient yet beautiful roads and bridges.

In 1984, Daewoo E&C completed the construction of Dongjak Bridge, the nation’s first such structure designed to carry both road and subway traffic. We also built the Gwangan Bridge in Busan, the nation’s largest double-layered bridge over water, spanning 7.4km. The 8.2km-long Geoga Bridge, which connects Geoje and Busan, drew international acclaim as being the world’s longest structure also built at the world’s deepest underwater depth.
We showed differentiated technical skills overseas by constructing sea bridges in Bihar and Mumbai in India and a composite bridge connecting Botswana and Zambia in Africa.
Especially, Kazungula Sea Bridge that dramatically changed the logistics industry of Africa received Grand Prize in the ‘Korea Civil Engineering and Architecture Awards’ in 2021.

Railways & Subways

Daewoo E&C is actively involved in major railway network and subway construction projects.
We maximize the convenience of life and the efficiency of industries by drawing on our extensive experience and leading-edge design and construction capabilities.

Daewoo E&C boasts industry-leading technology and construction experience in the high-speed railway area.
With a track record of having undertaken the largest number of sections of high- speed railway projects in South Korea, we have contributed greatly to South Korea being fifth in the world in total number of HSRs, by combining advanced mechanized construction technology with safe construction technology.
We are also recognized for our leadership in subway construction.
We have participated in the construction of almost all subway lines in Seoul and other major centers.
We have demonstrated our technological prowess by employing the nation’s largest diameter shield tunneling method to construct the extension of Bundang Line, and through the the wide area express railway in the metropolitan area (GTX-A) project, featuring a 50m underground road linking Paju, Seoul, and Dongtan. We are also actively exploring overseas markets including the Singapore Mass Rapid Transit.

Harbors & Reclamation

Infrastructure that enables the efficient use of harbor facilities and other water resources plays an integral role in invigorating national economies and energy efficiency through exports.
Daewoo E&C has garnered international recognition for its technology in this area, with a solid track record in developing harbors, shipyards and dams at home and abroad.

Daewoo E&C has become a leader in South Korea in the construction of harbor facilities - including revetments, breakwaters and seawalls.
By building the Busan Port - the nation’s largest container port - we supported the emergence of Busan as a globally competitive logistics base.
Overseas, we have completed the repair of many shipyards, including in Oman and Qatar.
We have also introduced top of the line harbor construction technology, exemplified by our container terminal in Algeria and our global-scale breakwater project in Iraq.
We also take pride in our differentiated technology expertise.
A prime example is South Korea’s Sihwa Lake Tidal Power Plant, the largest such facility in the world, which is now producing electricity that can be used year-long by 500,000 people.

Environment

The environmental industry requires proactive action and investment to allow for the sustainable development of our global human society.
Daewoo E&C invests in innovative technology development that is leading the way in future energy generation and supply.

Daewoo E&C has consistency proven itself to be South Korea’s top performer in the innovative construction of water treatment facilities, including sewage treatment, water purification plants and sewage pipelines.
By developing new technologies such as eco- friendly designs and Daewoo Nutrient Removal (DNR) sewage treatment, we have taken the ground-breaking approach of moving all treatment facilities underground, creating parks above the ground and improving public amenities.
We are also becoming a recognized leader in the green energy business.
For example, we have secured New Excellent Technologies, patents and the ability to carry out projects in the field of biogas power generation.
We have also successfully completed the Jeju solar power generation project through ongoing investments in solar power, wind power and other forward-looking businesses.

Leisure

The creation of modern leisure facilities requires a proactive anticipation of and response to the ever-changing consumer trends and desires.
Daewoo E&C is committed to meeting this challenge by constructing a wide range of leisure facilities that allow for enjoyment and play amidst our hectic modern lifestyles.

Daewoo E&C entered the leisure facility sector by completing the construction of Suyeongman Bay Yachting Center in 1986.
Today, our highly regarded construction approaches seamlessly integrate nature into our designs.
The golf courses we have constructed have solidified our reputation as forerunners in the leisure culture sector.
We have greatly increased the quality of construction of golf courses in South Korea, which include the Yeongcheon Country Club - whose development was designed and supervised by Vijay Singh - and the Adonis CC in Pocheon, Gangwon Land, which is located 1,150 meters above sea level.
Overseas, we built the LaoLao Bay Golf & Resort in Saipan.
