The Ha Giang Canal Embankment, a recently completed project to prevent erosion, stretches over 3km from the administrative center of Giang Thanh district to the Dam Chit residential area in Tan Khanh Hoa commune. The project, which includes auxiliary features such as sidewalks, greenery, drainage, and lighting, was accepted and inspected in mid-March 2024, after 18 months of construction, with a total investment of 80 billion VND from the central budget.
However, just 5 months after its completion and handover, a section of the embankment approximately 70m long has collapsed, raising concerns and questions among locals about the quality of the construction.
Serious erosion of the Ha Giang Canal Embankment just 5 months after its completion.
According to the People’s Committee of Giang Thanh district (the project investor), the structure had previously shown signs of foundation settlement, and the District Project Management Board had requested the contractor and consulting supervisor to remove the paving bricks and redo the construction.
On August 4, it was discovered that three segments, A35, A36, and A37 (with an embankment height of 3.5m), had tilted towards the river, with an inclination of 50-100cm from their original position. The following day, on August 5, the embankment collapsed.
Following the incident, the investor’s representative coordinated with the contractor and supervisor to assess the scene, set up warnings, and erect a fence. Due to the collapse of the embankment wall, which fell towards the Ha Giang Canal with a length of nearly 70m, the local authorities decided to remove the soil from the three affected segments to reduce the load, conduct geological surveys, and devise a solution to stabilize the entire embankment line.
In terms of a remedial plan, the contractor will dismantle and rebuild the three collapsed segments entirely, as the project is still within the warranty period.
The People’s Committee of Giang Thanh district also stated that they would scientifically assess the stability of the entire embankment. Additionally, they requested the consulting supervisor to maintain a constant presence at the site during the remedial works and promptly report any issues or developments to the investor.
