On August 24th, the Vietnam Airports Corporation (VAC) provided information regarding the disqualification of eight businesses belonging to the Deo Ca Consortium during the technical round of bidding for Package 4.7, worth over VND 6,300 billion, under Component 3 of the Long Thanh International Airport project in Dong Nai province.
Package 4.7 involves the construction and installation of aircraft parking aprons, passenger terminals, and other works for Component 3 of the first phase of the Long Thanh International Airport project. Two consortia participated in the bidding process.
Consortium 1 (Deo Ca Consortium) comprises eight contractors, led by Deo Ca Corporation Joint Stock Company. The remaining members of Consortium 1 include Deo Ca Construction Joint Stock Company, Deo Ca Infrastructure Investment Joint Stock Company, Lizen Joint Stock Company, Thang Long Corporation – JSC, Hoang Long Investment and Construction Corporation – JSC, Hoa Hiep LLC, and Son Hai Group LLC.

The Long Thanh International Airport project in Dong Nai province is currently underway.
Consortium 2 consists of six contractors: Airport Construction Corporation ACC, Truong Son Corporation, Vietnam Import-Export and Construction Corporation JSC, Vietnam Development and Investment Construction JSC, Cienco4 Group JSC, and Aviation Construction Company 647 JSC.
Following the announcement of the bidding results, Deo Ca Corporation Joint Stock Company, the leader of Consortium 1, submitted Document No. 1073 dated August 15, 2024, requesting the “Cancellation of Decision No. 3338/QD-TCTCHKVN dated August 12, 2024, and Announcement No. 3351/TB-TCTCHKVN dated August 13, 2024, regarding the bidding results of Package 4.7 of the Long Thanh Airport project.”
In response to this issue, VAC stated that it has issued a document addressing the petition of Deo Ca Corporation Joint Stock Company, which was sent to the eight contractors in Consortium 1.
VAC representatives affirmed that the bidding documents for Package 4.7 were prepared following Form 03B (E-ITB for construction, single-stage two-envelope bidding) issued together with Circular No. 06/2024/TT-BKHDT dated April 26, 2024, by the Ministry of Planning and Investment. The bidding documents were approved by the investor and published on the National Bidding Network to ensure transparency and fairness in the bidding process.
During the preparation of the bidding proposals for Package 4.7 until the submission deadline, the inviting party provided responses to all requests for clarification of the bidding documents from interested contractors and published the clarifications on the bidding network in accordance with legal regulations.

Once completed, this will be the largest airport in the country.
Therefore, it is entirely inappropriate for the Deo Ca Consortium to submit documents expressing their opinions and providing additional information on the bidding network after VAC announced the results of the technical proposal evaluation, in which this error was communicated.
According to VAC, the evaluation of the technical proposals of the bidders was conducted by the inviting party in strict adherence to legal regulations and the requirements of the bidding documents. This included the following steps: checking and evaluating the legality of the technical proposals; evaluating the capacity and experience; and evaluating the technical proposals. Only bidders with valid bidding proposals were considered for evaluation of their capacity and experience, and only those with sufficient capacity and experience were evaluated for their technical proposals.
VAC affirmed that the bidding proposal of the Deo Ca Consortium did not meet the eligibility requirements. Specifically, one of the consortium members, Hoang Long Investment and Construction Corporation – JSC (code VN2800177056 on the National Bidding Network), had been temporarily suspended on the system from June 30, 2024, until the approval of the list of technically qualified bidders.
Based on this, VAC asserted:
“The consortium’s request to cancel Decision No. 3338/QD-TCTCHKVN dated August 12, 2024, and Announcement No. 3351/TB-TCTCHKVN dated August 13, 2024, is unfounded.”
The investor addressed the petition following the proper procedures and in compliance with Article 91 of the Bidding Law No. 22/2023/QH15. Notably, the law does not mandate the suspension of financial proposal openings while petitions are being resolved.
Referring to Announcement No. 3351 dated August 13, 2024, on August 16, the inviting party proceeded with the opening of financial proposals from technically qualified bidders, as stipulated by law, ensuring transparency and witnessed by representatives of the participating bidders and representatives of the Economic Security Agency (A04) and the Police Agency for Investigation of Corruption, Economy, and Smuggling (C03) under the Ministry of Public Security, as invited through Invitation No. 3390 dated August 15, 2024.
“Thus, the consortium’s self-assessment that their technical proposal met the requirements is baseless,”
VAC stated.
