Research report on construction quality management of water conservancy projects

Our city’s water conservancy project construction mainly implements the project legal person responsibility system, bidding system, construction supervision system and other systems, forming a system guided by national macro-supervision and control, with the project legal person responsibility system as the core, the bidding system and The basic pattern of the construction project management system is that the construction supervision system is a service system. There are three market entities, including the project bidding and contracting system with the project legal person as the main body, the bidding and contracting system with design, construction and material and equipment supply as the main body, and the intermediary service system with the construction supervision unit as the main body. After the implementation of a quality management system that combines project legal person (construction unit) responsibility, supervision unit control, construction unit guarantee and government quality supervision, it has played an important role in the correct use of state investment and ensuring the quality of water conservancy project construction.

1. The main factors affecting the construction quality of water conservancy projects

The first is "personnel", including organizers, commanders and operators involved in basic construction. Every staff member directly or indirectly affects the quality of the project. The key to improving project quality is to improve people's quality, including people's political and ideological level, physical quality, etc. High-quality people and high-quality work lead to high-quality products.

The second is "materials". The management of materials should be controlled from the following aspects: strictly control the procurement of materials; use them rationally to reduce losses; establish an inspection system to strictly control quality; and reasonably handle remaining materials.

The third is "machinery". Construction machinery and equipment have a direct impact on construction quality. Therefore, when selecting construction machinery and equipment, attention should be paid to economic rationality, technological advancement, convenience in operation and maintenance, etc.

The fourth is "method", including construction plan and construction technology. Some projects often delay construction progress, fail to meet quality requirements and require additional investment due to poorly considered construction plans or backward construction techniques. Therefore, when formulating construction plans and construction techniques, a comprehensive analysis must be conducted in conjunction with technology, organization, management, economics and other aspects to determine whether the construction plan is technically feasible, economically reasonable, and conducive to improving project quality.

The fifth is "environment". The impact of environmental factors on project quality is complex and changeable. Therefore, beneficial measures should be taken to strictly control the environmental factors that affect quality based on the project characteristics and specific conditions. Especially at the construction site, an environment for civilized construction and production should be created. What is more important is to maintain good relations with local people and abide by local customs.

2. Improve the management level of construction units

At present, all newly started water conservancy construction projects in our city have established engineering project legal persons (water conservancy stations) units, forming a project legal person responsibility system. At the core, the basic structure of the construction project management system is the bidding system and the construction supervision system as the service system.

After the implementation of the project legal person responsibility system in the construction of water conservancy projects in our city, it has basically solved the problem of lack of responsibility in project construction, and is a major achievement in the reform of the construction management system. However, project legal persons and their institutions must effectively perform corresponding duties and assume corresponding responsibilities, which places high comprehensive requirements on project legal persons. Especially for public welfare projects, the project legal person should be responsible for the entire process of project construction, and have overall responsibility for the project quality, project progress and fund management; the project legal person must have political and professional qualities that are commensurate with the project scale and technical complexity. Organizational and management capabilities; the quality of the internal structure and personnel structure should be able to meet the requirements of project management and technical management, and at the same time have good moral character. It can be seen from these requirements that water conservancy project construction is a special industry with a wide range of expertise, strong technical skills, and high risks. To fulfill the construction and management responsibilities of the project legal person, one must be able to operate, be good at management, understand the profession, and must have people who are competent in planning and finance. Management, quality progress management, contract execution management, professional technical management and external coordination of the construction management team, the staff should have corresponding engineering experience, professional level and management coordination ability, and should have integrity and good anti-corrosion ability. At present, the project legal persons established by our city's water conservancy station are mainly station managers and engineers. Neither the staffing nor the academic qualifications and experience can fully meet the needs of construction management, and the management level needs to be improved.

3. Improve the level of supervision business

The construction supervision system emphasizes the target management of the project, hoping to implement target management of the project, especially the management of the project's cost, progress and quality targets. (Including project safety management, etc.), coupled with contract management, information management and comprehensive coordination, to achieve comprehensive management of the project construction process.

Construction supervision mainly solves the professional management of the project construction period, but the preliminary work of the project construction still requires the owner to undertake a lot of specific work, especially the feasibility study and engineering design of the project, which requires relatively long time. High technical management level, relatively high requirements for owner personnel. The early planning approval, immigration settlement, bidding management, etc. have also restricted a large amount of manpower and material resources from the owners, and are not in line with the reform model of separation of construction, management and maintenance proposed by the water conservancy system. At the same time, contrary to the original intention of implementing the engineering construction supervision system, the current implementation of the engineering construction supervision system has encountered an unprecedented "crisis of trust." Due to the rapid economic development of our city in recent years, the number of planned and under-construction projects has increased sharply. The number of qualified supervision units is limited, and the business volume far exceeds the capacity of construction supervision. Coupled with the weak construction supervision, a large number of The influx of supervisors who do not meet the professional qualification requirements into the supervision industry has led to a decrease in trust in the industry and directly led to the lack of basic conditions that could have achieved a smooth transition from the "engineering construction supervision system" to the "engineering project management system". Therefore, it is necessary to further strengthen the assessment of supervision units, and improving the level of supervision business is one of the keys to improving the quality of project construction in our city.

4. Strengthen the quality management of water conservancy project construction

1. Strictly implement water conservancy construction procedures

Strictly implement the "Interim Regulations on the Management of Water Conservancy Project Construction Procedures" and related documents, The important checkpoints such as project establishment, construction application, construction start, and completion acceptance shall be well controlled. If the work of any project in the previous stage is not completed, the next stage of work shall not be approved. Strictly enforce the engineering design approval system, and projects that have not been approved will not be allowed to start construction, and we will resolutely put an end to "trilateral" projects that involve approval, design, and construction at the same time. Quality assessment shall be carried out strictly in accordance with unit, division and unit projects. Any project shall not be put into use or proceed to the next stage of construction without acceptance. The evaluation opinions of the quality supervision agency must be obtained during project acceptance.

2 Vigorously promote the "three systems" in water conservancy project construction

Practice has proved that water conservancy project construction implements the project legal person responsibility system, the bidding contracting system and the construction supervision system (i.e., the "three systems") , is the fundamental measure to ensure project quality. Only when the project legal person takes full responsibility for the project construction can the project construction be organized in accordance with the laws of market economy and the project quality be guaranteed from all aspects of the project construction.

3 Strengthen leadership and implement the responsibility system

Whether the leadership pays attention to it is an important prerequisite for doing a good job in water conservancy project quality work. The water administrative department attaches great importance to the quality management of water conservancy projects and truly implements the project quality work with a sense of responsibility to the people and history. Comprehensively implement the responsibility system, clarify the responsibilities of unit leaders, project leaders, engineering technicians and specific staff, implement the responsibility system at all levels, and strengthen supervision and inspection. In accordance with water conservancy specifications and technical requirements, if quality problems occur, no matter what changes occur to the parties involved, they must be held accountable, that is, the project quality system is lifelong. Completely solve the problem of project parties simply walking away regardless of the quality of the project, so that engineering personnel can truly take responsibility.

4 Expand the quality supervision function and improve the quality level of the project

With the continuous improvement of the social benefits of water conservancy projects, the flood control and flood resistance capabilities have become increasingly significant, and their quality directly affects flood control. Safety and environmental protection affect the vital interests of the people. To this end, various measures should also be taken in terms of quality supervision:

① Strictly manage according to law. Strengthen the publicity of the "Construction Law" and other relevant laws and regulations to construction project survey, design, construction, construction parties and other units, and pay close attention to survey and design issues to ensure quality from the source.

②With the purpose of meeting project quality standards, we will increase efforts to promote enterprises to improve their quality assurance systems.

The improvement of project quality ultimately relies on the implementation of construction enterprises. Only by increasing the monitoring of various compliance standards can enterprises better promote the improvement of on-site quality assurance systems and lay a solid foundation for the quality of water conservancy projects.
