A Daewoo E&C led consortium has won the $639.1 million Zone 1 works at South Korea’s Yongin semiconductor national industrial complex. Korea Land and Housing Corporation selected the group after a construction management at risk evaluation. The zone covers about 3.45 million square meters, including the planned site of Samsung Electronics’ first fab there, and construction is expected to begin this year.
Daewoo Engineering & Construction leads the group with a 48% share, worth 416.9 billion won, of a total bid of 868.6 billion won ($639.1 million). Namkwang Construction, Jungheung Construction and Samho Construction complete the consortium. Seoul Economic Daily reported that Korea Land and Housing Corporation (LH) had estimated the infrastructure work at 987.2 billion won, which places the winning bid roughly 12% below that figure.
Daewoo E&C described the package as the largest public construction project of the year commissioned by LH. The company said it will begin site development in earnest once the main contract with LH is signed.
Yongin Semiconductor Complex Zone 1 Package Covers Roads, Water Supply and Sewage
The Yongin Advanced System Semiconductor Cluster National Industrial Complex Zone 1 works span the Idong-eup and Namsa-eup areas of Yongin, Gyeonggi Province. The zone accounts for approximately 44% of the entire complex site. At 3.45 million square meters, Yongin Semiconductor Complex Zone 1 is equal to roughly 480 soccer pitches.
The consortium will first build the infrastructure needed to operate the industrial complex. In addition, that scope includes roads, water supply systems and sewage systems.
Yongin Semiconductor Complex Zone 1 also contains the planned location of Samsung Electronics’ first semiconductor fab in the cluster. Site preparation therefore sits directly ahead of the chipmaker’s own construction program, which InvestKorea reports as a plan of 360 trillion won in total.
Daewoo E&C Consortium Wins Yongin Semiconductor Complex Zone 1 Under CMR Model
LH evaluated bids under the construction management at risk method. The Daewoo E&C consortium scored 310.8 points in the project plan evaluation and was named the winning bidder.
Jungheung Construction is also the parent company of Daewoo E&C, according to earlier reporting on the 2021 acquisition. As a result, two of the four consortium members sit within the same corporate group.
Daewoo E&C points to its record with LH as a factor in the award. Over the past three years, the company said it completed seven private-participation public housing projects for the agency, alongside the Gwacheon Knowledge Information Town development. Furthermore, it is leading the Gadeokdo New Airport site development and the Hongcheon Pumped-Storage Hydropower Plant.
A Daewoo E&C representative said the award reflects the company’s civil engineering capabilities and its ability to collaborate with LH. The company added that it will focus on safety and quality management so the complex can be developed without setbacks.
Yongin Semiconductor National Industrial Complex Plans Six Fabs and Three Power Plants
According to LH tender information reported in July 2026, the wider Yongin Semiconductor National Industrial Complex will cover about 7.78 million square meters in Cheoin-gu, Yongin. It is planned to integrate six fabrication plants, materials, components and equipment suppliers, three power plants and industrial gas supply facilities. LH is also reported to be aiming for a Fab 1 groundbreaking in 2028.
Meanwhile, the Zone 1 award is the first major civil package to be settled for the complex. Zone 1 alone represents a contract value of $639.1 million, yet the fab investments that follow are expected to be far larger.
Electricity supply is the constraint any chip cluster of this scale must solve, which explains why the Yongin complex plans three power plants of its own. Offshore wind is being positioned for the same demand region. The 1,125 MW Hanbando offshore wind farm, developed by Ocean Winds about 120 kilometers off Incheon, is designed to connect directly to the Seoul-Incheon metropolitan area, one of the country’s largest electricity load centers. Ocean Winds secured its electricity business license in March 2025, and the most recent confirmed status is pre-construction, with the environmental impact assessment and site investigations under way.
