Will people be compensated?

(NLDO)- According to the People's Committee of Ba Dinh district, the construction units of the Nhon - Hanoi Railway Station Metro project will be responsible for repairing and compensating if damage occurs.

On the afternoon of February 21, the People's Committee of Ba Dinh District (Hanoi) issued a notice to residents about the incident of a "stream" of mud spraying into the residential area of lane 7, Giang Van Minh Street (Kim Ma Ward, Ba Dinh District) caused by the underground construction of the urban railway project No. 3, Nhon - Hanoi Railway Station section.

Mud still filled alley 7 Giang Van Minh street on the morning of February 21.

According to the announcement, the representative of the joint venture of contractors and supervision consultants of the urban railway project No. 3, Nhon - Hanoi station section, affirmed that this was a phenomenon of tunnel drilling additives overflowing to the ground, a technical incident that was within the plan. "The additive solution (Bentonite) during construction is a non-toxic solution, so people should not panic or worry. Along with that, the construction unit is responsible for remedying and compensating if there is any damage to people or property" - the announcement clearly stated.

According to the People's Committee of Ba Dinh District, Lane 7, Giang Van Minh Street, has more than 30 households living there. Before the incident, 15 households had temporarily relocated, and 3 households (potentially directly affected by tunnel construction) had handed over the site to the investor.

On the same afternoon, the Hanoi Urban Railway Management Board (MRB) - the investor - said that after the incident occurred, the Board directed the consultant and contractor to urgently mobilize 6 mud suction trucks, 2 road washing trucks and 100 workers to fix it according to the project's process, including cleaning up the drilled mortar and cleaning the surface of the area where the mortar was sprayed, monitoring and standing by at the scene to monitor developments, taking timely response measures, ensuring safety and environmental sanitation.

MRB’s announcement also confirmed that the tunneling additive that erupted on the road surface was completely harmless and environmentally friendly. The above phenomenon did not affect the structure of the project nor did it cause any human damage.

MRB also said that tunnel boring machine No. 1 is still operating. So far, tunnel boring machine No. 1 has dug 1.2 km and is still continuing to work at an average speed of 10-12 m/day.

Previously, as reported by Nguoi Lao Dong Newspaper , at around 3:00 p.m. on February 20, residents in Lane 7, Giang Van Minh Street discovered a lot of mud and dirt rising from the drainage manholes, so they reported it to the authorities. This is the area where the underground section of the urban railway line No. 3, the Nhon - Hanoi Railway Station section, is being constructed.

Regarding the cause, MRB said it could be due to the existence of old wells or sewers underground that created a path for the tunneling additives to flow up to the surface (these old wells and sewers are no longer in use).

According to the project process, before the tunnel construction, the consultant and contractor conducted a survey of the works along the route. However, due to the change of ownership of the works over time, many information were not fully provided, so it was inevitable that there was still a lack of data on underground works such as water wells, residential wells, or geological survey boreholes from previous projects that were not filled. During the drilling process, tunneling additives were sprayed under pressure to stabilize the soil in front of the excavation face. When encountering open holes such as water wells or boreholes, the tunneling additives will flow up to the ground surface through these voids.

According to MRB, this phenomenon only occurs for a short time and ends immediately after the TBM drills through and installs the tunnel lining. This is a common phenomenon during the construction of urban tunneling projects.

The investor confirmed that the above phenomenon did not affect the structure of the project nor did it cause any damage to people or property. MRB is working closely with relevant units to accurately assess the cause and deploy technical measures to prevent similar incidents in the next phase.

Urban railway project No. 3, Nhon - Hanoi station section is 12.5 km long, with 8 elevated stations and 4 underground stations. Of which, the elevated section Nhon - Cau Giay is 8.5 km long (in commercial operation), the underground section Cau Giay - Hanoi station is 4 km long.

The project started in 2009 and was scheduled to be completed in 2015, but the schedule was delayed many times and is expected to be completed in 2027.
