The reclamation project for the Gadeokdo New Airport has officially commenced, led by a consortium headed by Daewoo E&C - Changes in the bidding landscape following the withdrawal of Hyundai Engineering & Construction, POSCO, and Lotte Construction.

Gadeokdo New Airport land development project, commencement schedule visible for the second half of the year

The construction of the Gadeokdo New Airport, a major national project in southeastern Busan, is now being actively carried out.

The Gadeokdo New Airport Construction Corporation plans to simultaneously progress administrative and bidding procedures with the goal of starting the priority land development work in the second half of this year.

To that end, land acquisition is set to begin in February, followed sequentially by temporary relocation of residents and compensation procedures starting in April.

After evaluating the basic design, the qualified contractor for the implementation design will be selected by August, with contracts expected to be finalized in the second half of the year to commence full-scale construction.





Withdrawal of Hyundai Engineering & Construction and POSCO E&C, transition to Daewoo Engineering & Construction's leadership

The most significant change in this project is that Daewoo Engineering & Construction has clearly taken on the central role in the construction consortium.

Initially, Hyundai Engineering & Construction was selected as the preferred negotiator with a stake of over 25%, but due to differences in opinions regarding the construction period and conditions, it decided to withdraw from the project in 2025. Following that, POSCO E&C also exited, causing a temporary stagnation in the project. However, with Daewoo Engineering & Construction's active involvement, a new consortium formation was quickly underway.

In response, the government has adjusted the construction period from the original 84 months to over 106 months, and the total project cost has been revised to approximately 10.7 trillion won to improve the conditions for project advancement.




Daewoo Engineering & Construction secures over 30% stake, to have substantive construction responsibility

Daewoo Engineering & Construction is expected to take the lead in the Gadeokdo New Airport land development project with an ownership stake of over 30%. This is interpreted as an intent to clarify the leading authority and responsibility for the construction.

Currently, several large and mid-sized construction companies, including Hanwha Construction, HJ Heavy Industries, Jungheung Construction, Kumho Construction, and Dongbu Construction, as well as local companies in Busan, have expressed their interest in participating, thus expanding the size of the consortium.

However, Lotte Engineering & Construction has decided not to participate in the first PQ submission, increasing the likelihood that Daewoo Engineering & Construction will secure its stake first. Consequently, Daewoo's final stake is expected to increase further. These changes will have significant implications for the future direction of the Gadeokdo New Airport project.




Possibility of solo PQ submission, scenario for private contracts after failure

Industry attention is focused on the possibility that the Daewoo Engineering & Construction consortium may submit a proposal alone in this bidding. The preliminary review for bidding participation eligibility is set to close on January 16, and if competition does not form, it could lead to a scenario of private contract negotiations following failure.

In this process, the share structure with participating companies may be adjusted slightly, but there is a prevailing analysis that the dominant position of Daewoo Engineering & Construction is unlikely to be shaken. This is because discussions on the sharing of the basic design service fees and the allocation of shares have progressed significantly. Consequently, expectations for future directions are high.




Construction roadmap for Gadeokdo New Airport intensifying after 2026

The Gadeokdo New Airport land development project is expected to take more than 100 months and is proceeding as a large-scale civil works project costing trillions of won.

Groundbreaking is anticipated to begin in the second half of this year, with more than 20 licensing procedures, including environmental impact assessments and disaster impact assessments, concurrently in progress.

This project is expected to become a crucial infrastructure not only for airport construction but also for Busan's global hub strategy and the concept of the southern mega-city.




Conclusion: Restructuring centered on Daewoo Engineering & Construction, entering the normal track for the Gadeokdo New Airport project

The Gadeokdo New Airport site development project faced temporary challenges due to the withdrawal of Hyundai Engineering & Construction and POSCO E&C, but is regaining momentum as it has been restructured into a consortium led by Daewoo Engineering & Construction with more than 30% stake.

This institutional change has led to an extension of the construction period and adjustments to the project budget, allowing for serious construction to commence after 2026.

While the results of the PQ and the final stake structure are yet to be confirmed, the Gadeokdo New Airport is once again gaining prominence as a future infrastructure project for Busan.
