📋 Tender Overview
Deputy Prime Minister Tran Hong Ha assigned the Ministry of Construction, the Ministry of Agriculture and Environment to review the article reflecting the investment rate of highways on the viaduct in the Mekong Delta area; direct and handle according to its authority. Processing information reflecting on the construction of the highway in the Mekong Delta - Artwork. VnExpress electronically issued on May 8, 2025, which reflects the investment rate of highways on the viaduct in the Mekong Delta area. The article stated: The Institute of Economic Construction has just reported to the Ministry of Construction on the results of the research on the investment in viaduct to build high -speed car roads in the Mekong Delta. Accordingly, if only considering the initial investment cost, the viaduct has an investment rate of 383 billion VND/km, 2.6 times higher than the ground highway. This investment does not include ground clearance, loan interest during the construction period, environmental impact assessment, weak ground treatment, also pointing out many disadvantages of the plans of embankment such as large site clearance, dependent sand source is scarce, subsidence risk, landslide, and long -term land treatment time. Meanwhile, viaduct with reinforced concrete can overcome these issues, with the advantages of fast construction, saving land fund, facilitating flood drainage, reducing the risk of saline intrusion and environmental impact. In addition, the reinforced concrete foundation structure of the viaduct helps to stabilize the foundation, not subsidence, easy to maintain, less intersection and less population division. The construction economy is said that if only the initial cost is considered, the viaduct is somewhat more expensive, but if the entire life cycle is not significant. Therefore, the Institute proposes high -speed projects in the Mekong Delta, so it combines both plans to build and build viaduct, depending on geological conditions, materials and the environment in each area, besides, the construction industry is recommended to promote research and application of new technologies such as large aperture beams made from high -intensity concrete (HPC) or super high (UHPC), to reducing the price of sand, reducing the price of the sand, reducing the price of the sand, reducing the price of the price, reducing the amount Prime Minister Tran Hong Ha assigned the Ministry of Construction, the Ministry of Agriculture and Environment to consider the contents of the above article; direct and handle according to the authority and provisions of the law.
