Why are there frequent accidents in building demolition projects?

Why are there frequent accidents in building demolition projects? What is the specific content? Zhong Da Consulting will answer your questions below.

A, the construction unit (or contractor) illegal contract.

After investigation, there are still a considerable number of building demolition contractors who have no professional construction qualifications. According to Article 50 of the Building Law and Article 1 1 of the Regulations on Safety Management of Construction Projects, the building demolition project must be carried out by a construction unit with the professional construction qualification of demolition project. Article 4 1 of the Law on Safety in Production also stipulates that production and business operation units shall not contract out or lease production and business operation projects to units or individuals that do not have the conditions for safety in production or the corresponding qualifications.

In 2004, there were three demolition accidents in Nanchong City, all of which were caused by the fact that the construction unit did not conduct serious qualification examination when awarding the contract, and the construction unit that did not have the demolition qualification contracted the project. Among them, the drying shed demolition project of Nanchong Meiya (Group) Silk Company was contracted by a private machinery factory without any demolition experience; The demolition project of students' apartments in Zhoukou Middle School in Peng 'an County and the demolition project of residents' houses in Xinzheng Town of Yilong County were subcontracted many times, and were finally contracted by unqualified and inexperienced self-employed individuals.

Second, the demolition project started without authorization.

Most building demolition projects started to operate without going through the construction procedures according to law. Article 1l of the Regulations on Safety Management of Construction Projects stipulates that the construction unit shall, before the demolition project starts 15, submit the qualification grade certificate of the construction unit, the description of the buildings and structures to be demolished and the adjacent buildings that may endanger them, the demolition organization plan, the measures for stacking and removing wastes and other materials to the construction administrative department of the local people's government at or above the county level or other relevant departments for the record. Judging from the past accidents, there are not a few cases in which the construction unit failed to file with the relevant regulatory authorities as required, resulting in the safety supervision of the demolition project being out of control.

Third, the construction unit took the risk.

Demolition construction units or individual contractors have weak legal awareness, are driven by interests, and ignore the investment in safety production.

Before operation, the construction unit failed to prepare the special operation plan and technical disclosure before shift as required; No safety precautions are set in the operation, and no full-time safety management personnel are equipped, allowing the operators to take risks in violation of regulations. For example, the collapse accident of the student apartment demolition project in Zhoukou Middle School in Peng 'an County, the original building structure was not carefully analyzed before the demolition, and the demolition plan was not compiled. The demolition sequence was wrong during the operation, which led to the overall collapse of the transverse wall, resulting in 7 deaths and 6 injuries.

Fourth, employees have a weak sense of safety and lack of safety production skills.

According to the survey, at present, no matter how highly qualified construction enterprises win the bid, the construction of construction projects is basically completed by migrant workers recruited by the labor market. These personnel have not received basic safety training, do not understand or are not familiar with safety standards and operating procedures, and have insufficient understanding of the dangers of demolishing dangerous houses. Due to the lack of management, illegal operations have not been corrected and stopped in time, and hidden dangers of accidents have not been discovered and rectified in time, which is an important reason for accidents.

Verb (abbreviation of verb) responsibility is not implemented and supervision is out of control.

The relevant departments failed to perform their safety management duties seriously, or the responsibilities were not implemented or the supervision was not in place, which led to the out-of-control supervision of the demolition project.

For example, the demolition project of student apartment in Jukou Middle School in Peng 'an County collapsed, and the supervision of individual functional departments was absent; The construction unit did not designate a person to be responsible for the on-site supervision of the demolition project of dangerous houses; R_ 1, the education department of Peng 'an County failed to supervise the school signing and filing according to law, resulting in the loss of effective supervision; The construction administrative department failed to discover and stop illegal construction in time, did not conduct a comprehensive survey of dilapidated buildings and old house renovation projects within its jurisdiction, did not grasp the dynamics of house demolition projects, did not urge the house owners to declare according to law before the implementation of house demolition construction, and did not track, supervise and manage the implementation of the demolition construction plan.

Symptomatic treatment:

First, strictly implement the professional construction qualification system for demolition projects and the bidding system for large-scale demolition projects.

Strengthen the publicity of laws and regulations related to house demolition projects, strengthen the concept that house demolition projects must be undertaken by qualified construction enterprises, and strictly implement the bidding system for large-scale demolition projects.

Two, strictly implement the demolition project approval system or filing system, standardize the demolition project construction order.

In accordance with the relevant provisions of the Building Law and the Regulations on the Administration of Work Safety in Construction Projects, the construction unit shall report to the local construction administrative department or the relevant competent department for approval or filing before the demolition project starts15; At the same time, provide the qualification grade certificate of the construction unit, draw up the demolition instructions and construction organization plan, and take measures to pile up and remove wastes, so as to avoid accidents caused by out-of-control supervision of demolition projects due to poor information.

Third, improve the current lack of qualified construction teams as soon as possible.

According to the survey, at present, there is only one enterprise in Nanchong that has obtained the qualification of professional demolition construction. Most counties (cities) have not yet engaged in demolition construction, and many projects are undertaken by enterprises with the qualification of building construction permit. Because of the small amount of work, low profit and high risk, many construction enterprises are unwilling to do it, resulting in most demolition projects being contracted by self-employed individuals who do not have the qualification for demolition construction.

Faced with a large number of building demolition projects in recent years, local governments and relevant competent departments should actively strengthen policy guidance, cultivate the building demolition market, and improve the status quo as soon as possible.

Four, strengthen the safety management of building demolition project.

Safety production supervision departments should clarify their responsibilities, conduct a comprehensive survey of the renovation projects of dilapidated houses within their jurisdiction, and grasp the dynamics of housing demolition projects; To urge all housing owners to declare according to law before the implementation of house demolition and construction; It is necessary to strengthen monitoring and supervision, and severely punish all kinds of illegal demolition projects and illegal demolition behaviors; Establish a long-term mechanism and issue special regulations and standards such as "Safety Management Measures for Building Demolition Projects" as soon as possible.

Five, conscientiously do a good job in safety education and safety skills training for employees of demolition projects.

The building demolition project is highly professional, dangerous and requires high construction technology. All construction units shall, in accordance with the provisions of the Safety Production Law, strengthen the education and training of employees in safety production, and the personnel engaged in special operations shall also obtain the qualification certificate of special operations.
