Tragedy struck when a nearly 1,500m2 concrete floor at the Tuyen Hoa Cultural Center collapsed due to a scaffolding system failure, injuring two workers. Discover the details of this alarming incident.
I. Detailed information about the concrete floor collapse accident in Quang Binh
On September 17, a serious accident occurred at the Tuyen Hoa District Cultural Center construction site in Quang Binh when a concrete floor of over 1,500m2 suddenly collapsed. The incident occurred after more than 30 workers completed pouring concrete for the 3rd-floor roof of the structure. This happened around 11 AM, as the group of workers was preparing for their lunch break and noticed the scaffolding shaking, an unusual sign.
However, before they could react, the entire concrete floor in front of the building’s lobby collapsed, causing minor injuries to two workers. The vice-chairman of Tuyen Hoa district, Mr. Dinh Tien Dung, pointed out that the incident could be due to vibrations during the concrete pouring process causing the scaffolding to weaken or bend.
This prompted authorities to request the contractor to inspect and rectify the problem immediately. This project, which began in December 2022 with a total budget of 50 billion VND, is funded by the local government as the investor. The design of the structure includes 3 floors and a construction area of over 1,500m2, including a 400-seat auditorium and auxiliary facilities. The construction unit was assigned to the joint venture between Quang Truong Construction Co., Ltd. and Duc Thang Construction Co., Ltd.

II. Technical errors during the construction process caused the concrete floor collapse accident
The concrete floor collapse incident at the Tuyen Hoa District Cultural Center construction site in Quang Binh is believed to stem from technical errors during the construction process. Specifically, according to Mr. Dinh Tien Dung, Vice-Chairman of Tuyen Hoa District, some parts of the scaffolding may have been weakened or bent due to vibrations during the concrete pouring process.
This caused the scaffolding to shake, leading to the breaking and collapse of the entire concrete floor. This incident is a testament to the need for strict adherence to safety procedures and regular inspections during the construction process.
Regular technical inspection and maintenance not only help detect errors and dangers early but also ensure safety for workers and surrounding residents. This is something that needs attention and lessons learned in future construction projects, to avoid harmful consequences and unnecessary casualties.
III. Analysis of potential hazards and risks that were overlooked before the occupational accident occurred
Before the concrete floor collapse accident at the Tuyen Hoa District Cultural Center construction site in Quang Binh, there were potential hazards and risks that were not given proper attention. One of the risks was the failure to perform regular inspection and maintenance for the scaffolding system and steel floor props.
The abnormality in the scaffolding was recognized before the incident occurred, when the group of workers noted the signs of shaking, but there was no timely intervention. This shows a shortcoming in the inspection and risk assessment process of the construction project. In addition, the lack of strict control over the concrete pouring process also created conditions for unwanted incidents to occur.
For construction projects, ensuring occupational safety is not only a legal responsibility but also an ethical obligation of the involved parties. It is necessary to implement strict preventive and risk control measures from the planning stage to the completion of the project, to ensure a safe working environment and minimize the risk of unfortunate occupational accidents.

IV. Local authorities’ investigation to determine the specific cause
Local authorities conducted a thorough investigation to determine the specific cause of the concrete floor collapse at the Tuyen Hoa District Cultural Center construction site in Quang Binh. According to the investigation’s conclusion, the main cause was identified as a technical failure due to the scaffolding system being weak or bent.
This failure may have originated from the concrete pouring process, causing parts of the scaffolding to be insufficiently strong to bear the load and vibrations during work. Identifying this specific cause is important for implementing effective remedial measures and preventing similar incidents in the future.
The local authorities also requested the contractor to inspect and rectify the problem immediately, while strengthening supervision and strict compliance with occupational safety regulations in future construction projects.
V. The experience of survivors from the occupational accident involving the concrete floor collapse
The survivors who narrowly escaped the occupational accident of the concrete floor collapse at the Tuyen Hoa District Cultural Center construction site in Quang Binh went through a terrifying and astounding experience. They recounted the feeling of panic and helplessness as they saw the scaffolding shake and the concrete floor collapse before their eyes. Fortunately, the group of workers immediately recognized the dangerous situation and quickly escaped from the scene, helping them avoid more severe consequences.
However, having gone through this event, they witnessed the serious injuries and consequences caused by this accident, and realized the importance of adhering to occupational safety rules and conducting regular checks on technical systems during the construction process.
This experience also serves as a warning to all involved parties about the importance of ensuring occupational safety and implementing risk prevention measures seriously in every construction project.

VI. Consequences for the victims, families, and society
For those injured, the consequences can range from physical health problems to mental ones. They may have to endure much pain, recovery after the accident, and even lose their ability to work, greatly affecting their income and daily lives.
The victims’ families also face financial and emotional burdens, including caring for their injured loved ones and figuring out how to support them during the recovery process. In addition, the accident also created a wave of anxiety and stress in the community, especially in the construction and labor industries.
The consequences of this incident emphasize the need to promote occupational safety measures and protect workers’ rights, as well as building a safe and sustainable working environment for everyone.
VII. Preventive measures for hazards in construction projects
To prevent occupational accidents like the concrete floor collapse at the Tuyen Hoa District Cultural Center in Quang Binh, implementing preventive measures is extremely important during the construction of projects.
First, ensuring the scaffolding system and steel floor props are installed and inspected regularly is essential. Workers need to be trained and instructed on how to recognize unusual signs in scaffolding and other construction equipment to detect and handle potential hazards early.
In addition, applying safety measures during work, such as using personal protective equipment, adhering to safety procedures, and close supervision, is necessary. Contractors need to promote strict compliance with occupational safety regulations and ensure that all workers have safe working conditions.
Finally, establishing a safe work culture and creating a positive and encouraging work environment is also an important part of preventive measures.
