People will have to temporarily stay for a month to fix problems with underground metro station construction.

Some houses in lane 7 Giang Van Minh street (Kim Ma ward, Ba Dinh district) will have to be relocated for about a month so that the investor and contractor can fix the problem to ensure safety.

This afternoon (March 4), speaking with Giao thong Newspaper reporter, Mr. Nguyen Ba Son - Deputy Head of Hanoi Urban Railway Management Board (MRB) said: Regarding the crack next to the Nhon - Hanoi station metro tunnel, it is expected that displaced people will have to temporarily reside for about a month to fix it.

People have to temporarily relocate to serve the work of overcoming the incident of digging underground metro stations.

"The residents have been staying temporarily for a month. Currently, the contractor has to reinforce the ground with Jet grouting for at least 3 weeks, then check to ensure safety before they can return," said Mr. Son.

Previously, on the night of February 27, residents in lane 7 Giang Van Minh (Ba Dinh, Hanoi) - where the metro tunneling additive spill incident occurred on February 20, had to be urgently evacuated due to cracks appearing in their house walls.

According to residents in Giang Van Minh Street, they discovered small cracks on the street and house walls. Afterwards, they reported to local authorities and the contractor for monitoring. However, on February 27, the cracks grew larger.

At 2:00 p.m. on February 27, the investor and contractor held a meeting with the residents to discuss a solution. At 7:00 p.m. on the same day, more than 10 households were suddenly notified of an emergency evacuation to ensure safety, forcing residents to evacuate overnight.

According to MRB, during the construction of the tunnel section of the Nhon - Hanoi Railway Station metro project, the contractor used a modern geotechnical monitoring system to closely monitor ground displacement and subsidence.

On February 27, data showed that some areas had subsidence exceeding the warning threshold. Given this reality, MRB decided to relocate 11 houses in Lane 7, Giang Van Minh Street to temporary housing.

On February 27, MRB coordinated with local authorities to organize a meeting with residents at Kim Ma Ward People's Committee to discuss and agree on a plan to relocate affected residents.

"The unit will support each household with a total of 16 million VND to ensure a stable life during the temporary residence period. The households all agree with the project's support policy and coordinate closely to create conditions for the project to be implemented on schedule.

During the time the households are temporarily housed, the project will continue to conduct inspections, assessments and find solutions to reinforce the ground to ensure the safety of related structures. This process is expected to last about 1 month," MRB informed.

According to MRB, before starting construction, the investor required the contractor to purchase third-party liability insurance. As soon as signs of impact were detected, the insurance company conducted a survey, assessment and statistics to compensate for damaged houses, if any.

The Nhon - Hanoi Railway Station railway line is 12.5km long, including 8.5km above ground and 4km underground.

Construction began in September 2010 and was expected to be completed in 2016. The project's total investment increased from VND18,000 billion to VND34,532 billion.

At 8:00 a.m. on August 8, 2024, the Nhon - Hanoi Railway Station metro line officially began commercial operation of the elevated section from Nhon to S8 Station (Cau Giay), 8.5 km long.

Currently, the underground section of the project from Cau Giay to Hanoi station is still under construction, with no date set for commercial operation.
