Civil engineering is one of the most important projects in engineering construction, which relates to the quality of the whole engineering construction and is the key object of supervision and management. Therefore, quality supervision and management of civil engineering is an important link in engineering construction and use, and quality supervision and control is a complex system engineering. Quality is the life and foundation of architecture and an important goal of project management. Grasping the quality of engineering construction supervision is the purpose and means of construction.

1 quality problems and causes of civil engineering

1. 1 quality problem

Civil engineering is an indispensable construction project in the process of production and life. In engineering construction management, due to factors such as inadequate supervision of construction management and unqualified technology and materials, it often causes harm to engineering construction, ranging from unqualified building quality to major accidents. Therefore, the quality supervision and management of civil engineering is an important link in engineering construction, and we should pay special attention to, pay close attention to and strictly control the quality.

There are many kinds of quality problems in civil engineering, such as deformation, dislocation, collapse, damage, inclination, water leakage, water seepage, rigidity, insufficient strength, inaccurate cross-section size and so on.

Cause analysis of 1.2

There are many reasons for engineering quality problems, which can be summarized as follows.

1.2. 1 violates the construction procedure. The construction unit does not operate the project in accordance with the corresponding construction norms and procedures.

1.2.2 did not seriously carry out geological survey and provide accurate geological data.

1.2.3 The foundation has not been reinforced properly.

1.2.4 The design is thoughtless and the designed structure is not reasonable enough.

1.2.5 raw materials and products are unqualified.

1.2.6 There is something wrong with the construction management, and the construction unit does not follow the drawings.

1.2.7 the influence of various natural conditions.

2 engineering quality control

Engineering quality control is the standard and assessment of engineering project quality, which plays a guiding role in engineering construction and project management, is an important technical link of engineering construction and the main factor of project completion. To build a qualified project, in fact, we must do a good job in quality control from all aspects, mainly in the following aspects.

2. 1 Strengthening the bidding management system of engineering projects

The design, construction and supervision of general civil engineering are determined through bidding. Bidding shall be conducted in a fair and reasonable manner in accordance with the provisions of the state and the rules of the owner. Bidding should be completely market-oriented and socialized, so that more units or individuals can participate in the competition. Only in this way can we really find high-level and powerful enterprises to design, construct and supervise.

2.2 Inspection of raw materials

All kinds of raw materials used in civil engineering must undergo strict inspection before construction, and the technical performance of raw materials can only be used after meeting the specific requirements of relevant specifications. When purchasing raw materials, the construction unit should strictly control the quality of raw materials, attach great importance to the use certification of raw materials and avoid using unqualified raw materials.

2.3 Strengthening engineering design

Engineering design should be divided into two stages. The first stage is the design before the project construction, which is the most critical. It is also important to supplement and improve the design in the second stage. The design department should often go to the construction site to communicate with the construction unit, solve the problem of engineering change at any time, ensure the smooth progress of the project, make the project reasonable and practical, and ensure that the project reaches the excellent standard.

2.4 Strengthen the construction of the construction team

The construction level and quality of the construction unit are directly related to the success or failure of the project quality. The construction quality of the construction unit is also the guarantee for the smooth completion of the construction, and only good construction units are qualified to undertake large-scale engineering construction.

2.5 control the progress of the project

The progress of the project is the main factor restricting the quality of the project, and reasonable arrangement is an important means to speed up the construction. In order to improve the project quality, we must make the project schedule obey the project quality, and arrange the project schedule reasonably under the condition of fully ensuring the project quality.

2.6 Play a supervisory role

Supervision is the core of project management and an important guarantee of project quality. Supervision should have higher professional and technical level, good professional ethics and the spirit of hard work. The construction unit shall supervise the supervision unit through contract to improve the professional quality of supervision.

In a word, engineering quality is a complex problem, involving many factors. To completely solve the engineering quality problem, we must start from every detail and strictly control the quality.

3. Supervision of project quality 3. 1 actual supervision of the project

The implementation of project quality supervision is a government supervision behavior to urge contractors to do a good job in project quality and project quality control. Therefore, in engineering construction, the engineering quality supervision station should focus on the "three customs", namely, the start-up, construction and completion customs; Make good use of "three rights", namely, quality supervision right, quality veto right and quality arbitration right; Grasp the "triple", that is, the key work, key units and key parts of the project construction; In order to reflect the "three characteristics" of quality supervision, that is, authority, scientificity and impartiality, quality supervision should run through the whole project.

Before the project starts, the quality supervision station shall, according to the application procedure for project quality supervision declared by the owner, conduct qualification examination on the construction, survey, design, construction, supervision and testing parties of the construction unit one by one. Supervise all parties to establish and improve the quality supervision and guarantee system in accordance with the relevant provisions of the state, and ensure that the personnel of supervision institutions and construction units are in place and equipped with professional posts. In the process of project implementation, supervise and inspect the quality assurance system of the construction unit, and supervise the integrity of the quality assurance system and the implementation of the quality responsibility system. Through inspection and supervision, the control system of self-inspection, mutual inspection, random inspection and special inspection is formed in quality control, and the signature responsibility system is implemented. If there is a quality problem, the responsible person will be directly investigated. And supervise and inspect the laboratory to see whether it is tested according to the specifications and standards, whether it reaches the testing frequency, and whether the data is true and reliable.

Focus on supervision and supervision to realize on-site supervision. Engineering supervision is to control the quality, progress and investment of the project according to the contract. Therefore, the quality of supervision work directly affects the engineering quality. Supervision is an important part of government supervision. In addition to checking the qualification and certificate of the construction unit, the supervisors should also conduct spot checks on their on-the-job situation, log records, side stations, visas, etc., focusing on the work-start report, process self-inspection report, intermediate handover report and intermediate background recognized by the supervisors.

Strengthen sampling inspection on the construction site and strengthen supervision. The most effective way to master the quality dynamics is to conduct on-site sampling inspection. According to the progress of the project, the quality supervision station will timely arrange on-site sampling inspection for the parts and places that are prone to quality hidden dangers or have doubts about quality, and timely issue the Notice of Supervision Engineer for the problems found, instructing relevant units and personnel to correct them. To seriously affect the construction quality, be responsible for stopping work and report to the relevant departments. Quality problems should be "three don't let go", that is, the cause of the accident is not found out, the person responsible for the accident is not punished or educated, and the rectification measures are not let go.

In a word, quality appraisal is an important part of quality supervision. In order to ensure the objectivity, fairness and scientificity of quality appraisal, it is necessary to strictly appraise the procedure and speak with data to ensure the authenticity and reliability of the appraisal results.

3.2 Comprehensive supervision and management measures

In engineering construction, people play a leading role, which is the direct factor of quality inspection and the main body of engineering construction. Therefore, the supervision of construction projects begins with managers, mainly in the following three aspects:

3.2. 1 It is necessary to improve the post responsibility system and bind people with rules and regulations.

3.2.2 Management personnel should be selected and trained.

3.2.3 Choose a construction team with stable personnel and strong technical force.

People-oriented is the slogan of safe construction and the principle of supervision and management. Managers should do a good job of supervision and ask the construction unit to modify the scheme or stop the construction that is unqualified or has serious quality problems in time.

While strengthening personnel management, we should also comprehensively consider various factors such as construction site conditions, building structure, mechanical equipment functions, construction technology and methods, construction organization and management, construction technology and economy. , so that they are reasonably equipped, used together, organically linked, give full play to their effectiveness, so as to obtain good economic benefits.

4 conclusion

The supervision and management of civil engineering construction quality is the key to engineering construction and the system that should be followed in the construction process. To strengthen the supervision and management of civil engineering quality, we must strengthen the construction of legal system, constantly improve the legal system of engineering quality supervision and management, and manage civil engineering quality according to law. In engineering construction, the quality of engineering construction projects should be guaranteed, and supervision and management should be carried out in accordance with regulations. Only by strengthening the government's supervision and management functions, strengthening the quality construction of supervisors and constantly improving their professional and technical quality can civil engineering projects be successfully completed and used safely.
