Saltwater intrusion prevention dam project on Cai River, Nha Trang: Urgent completion

Speed up construction progress

The project of the saltwater intrusion prevention dam on the Cai River in Nha Trang is very important, not only solving irrigation problems such as: preventing saltwater intrusion, ensuring flood drainage, providing water for daily life and production, but also supporting traffic improvement, improving the urban environment, promoting tourism development along the Cai River, contributing to the development of the Nha Trang area and Khanh Hoa province. Therefore, speeding up the progress and putting the project into operation soon is very necessary.

The saltwater intrusion dam project on Cai River in Nha Trang is being accelerated.

According to the reporter, these days, at the construction site of the dam to prevent saltwater intrusion on the Cai River in Nha Trang, the working atmosphere is urgent and bustling day and night. The sound of excavators, bulldozers, and cranes resonates with the urgent steps of dozens of engineers and workers working hard. Dozens of modern equipment and vehicles are mobilized, operating in harmony with each construction item. All are aimed at speeding up progress, ensuring quality and absolute safety for this key project. The competitive atmosphere and the spirit of determination to complete the project on schedule spread strongly throughout the construction site.

Directly directing at the construction site, Mr. Nguyen Thanh Hien - Director of the Provincial Development Project Management Board (the investor), said: "Although the project's site clearance work has been implemented since 2019, due to the impact of the Covid-19 pandemic, the land acquisition was interrupted. It was not until 2022 that the People's Committee of Nha Trang City (old) was able to issue land acquisition decisions and approve compensation plans. In addition, the disagreement of some households was also the reason for the delay in handing over the site. In particular, some construction items are located on land belonging to the Ngoc Hoi Ring Road Project - this project has temporarily stopped construction. To resolve this situation, the Provincial People's Committee promptly approved the policy to allow the saltwater barrier dam project to receive compensation payments for 10 cases affected by the ring road project. With the participation and determination of relevant agencies, by June 2025, all site clearance work will be completed. The project's certificate has been completed and the land has been handed over to the contractor to construct the remaining items. Up to this point, all difficulties and problems have been resolved, and the project is entering the final stage.

Handed over and put into use in December

It is known that up to now, the project has completed pouring reinforced concrete for the entire main dam and boat lock; installed hydraulic cylinder system, dam gate and boat lock gate; reinforced concrete for traffic bridge piers reaching 8/8 piers. The contractor is speeding up the construction progress of the items, including: Reinforcing the riverbed, reinforcing the embankment on both banks (reaching 95%); launching and installing beams and the entire reinforced concrete of the bridge deck, the superstructure of the traffic bridge (reaching 95%), only the lighting and asphalt concrete of the road surface remain; technical infrastructure and leveling the ground on both banks (reaching 90%); and the operator house item (reaching 97%).

It is expected that the project will be put into operation in December.

According to the investor's assessment, up to now, the completed construction volume has reached about 92%. The contractor is continuing to construct the approach roads at both ends of the bridge, leveling the technical infrastructure, landscaping, completing the SCADA control system (monitoring, control and data collection), technical electricity, and lighting. Operation training and trial operation are expected to be carried out in November and the project will be completed and put into use in December. To speed up the progress, the investor has arranged management staff to directly monitor the construction work at the site; directed the supervision consultant and contractor to regularly increase human resources, materials, and equipment to organize construction in 3 continuous shifts, closely following the plan committed to the Provincial People's Committee.

Mr. Nguyen Thanh Hien said that in addition to speeding up the construction progress and ensuring the quality of the project, the disbursement of public investment capital for this project is also very important. The Board has proactively made specific plans for each month and quarter, closely following the implementation progress and actual payment needs. The cumulative capital disbursement in 2025 up to October 24 is 38.64/50 billion VND, reaching 77%; it is expected that by November, the project will disburse 100% of the capital plan for 2025.
