How to ensure the engineering quality

1 Scientific management, establishing and perfecting various management systems

Formulating post responsibility system and various rules and regulations is the primary task and important part of enterprise management. The project manager must attach importance to the establishment of the system, pay special attention to the supervision and implementation of the work at the construction site, and establish the post responsibility system of various personnel on the basis of the original rules and regulations and according to the actual situation of the site, clarify the responsibilities of the site management personnel, and post them in writing in the site office for comparison. At the same time, the operation and maintenance system of various machines and tools, electricity consumption, tic-tac-toe frames, external wall scaffolding and other equipment shall be defined, which shall be managed by special personnel to ensure that all the work is in place. The responsibility shall be carried out in the case of "Suifu Primary School" project: according to the actual situation of the construction site, the project department has established the dispatching meeting, analysis meeting, disclosure meeting, inspection and assessment system, and established the data filing system. Strengthen the plan management, according to the total schedule requirements, timely revise the plan according to the actual construction, realize the control of important nodes, and make the plan management in the best state. Establish a briefing system at the construction site, inform all parties of the project situation in time, and establish a summary system, thus greatly strengthening the on-site construction management and winning unanimous praise from all parties.

2. Raise awareness and strengthen the management of front-line workers

To improve the level of construction management, we must take the lead in thinking, that is, we must first raise management awareness. The core problem of an enterprise is management. Due to the great mobility of production workers, poor general technical quality, weak quality awareness, only focusing on work progress, ignoring the scale and quality of the project, coveting convenience, blindly seeking for speed, weak responsibility and poor safety awareness, construction management is very difficult, and these awareness and practices should be completely changed. On the basis of raising the awareness of managers, the project manager should also strengthen the management of production workers. The specific approach is to implement the principle of "one choice, two education and three management". The first choice is to implement the principle of "survival of the fittest" for production workers, and those production workers with poor safety awareness, low technical quality and disobedience to management must be eliminated. Second, education is not only the "three-level education" for workers before taking up their posts, but also the safety technical disclosure and safety technical visa before entering the site. A clear system of rewards and punishments must be implemented for workers in each construction team to fully mobilize the enthusiasm of workers and give play to their leading role. Pre-job training should also be carried out for operators of various types of work and major parts of each project. Three management is to do a good job of technical disclosure to production workers before construction, strictly control each working procedure during construction, follow up, supervise, record, review or spot check, and strictly control the quality from technical measures to actual operation. Adhere to the combination of self-inspection, mutual inspection and sampling inspection; Adhere to the specific practice that the previous process is unqualified and does not flow into the next process, especially for the types of work and processes that are prone to common quality defects, and carry out full-time follow-up construction to restrain common quality defects by compulsory means and change irregular practices.

3 Organize construction, and strive to do a good job in engineering quality and safety management

When directing various projects, the project manager must conscientiously do a good job in engineering quality and safety management, and organize many units in a construction site to carry out construction in a rhythmic and balanced manner, so as to achieve the effects of short construction period, good quality, safety and low cost. This is a very complicated problem, which includes technology, quality, safety, materials and cost.

therefore, in the construction management, it is necessary to implement institutionalization and networking, straighten out the company's management system, and institutionalize various management. The project manager should often organize professional business analysis meetings, and reflect the conclusions and information of various professional business analysis to the company in time, so as to better realize the comprehensive control of the on-site construction process.

in the management of the project, we should strictly follow the "three inspections, two persistence and one excellent" (i.e. self-inspection, mutual inspection and re-inspection; Adhere to the construction according to the drawings and the specifications; Excellent products) policy for construction, do the listing construction, responsibility to people, ideas in place. The quality management should attack common faults, create excellence and improve the quality of products, eliminate potential quality hazards in the bud of the construction process, check and accept every working procedure, and improve the primary survival rate of products. Strive for the excellent rate of the project to reach more than 8%. Strive to overcome and eliminate common diseases such as "seepage, leakage, shell, crack, pour, wool, roughness, blockage and pollution" in engineering, try to improve the engineering quality with management system and ensure the engineering quality with technical measures.

in terms of safety management, we should strengthen safety education and raise the safety awareness of workers and migrant workers. The company should be willing to spend manpower, material resources and financial resources to do a good job in safety facilities, and construction management personnel should do their duty. In the construction of Suifu Primary School, the education and protection of "Three Treasures and Four Doors" were particularly strengthened, and the practice of gantry and scaffolding being delivered for use only after passing the sectional acceptance was supported. Organize a voluntary fire brigade and be directly commanded by the project manager. Safety warning signs and safety slogans can be seen everywhere in the construction site, the purpose is to mobilize safely and do a good job in safety production.

in terms of technical data management, a person in charge of the project is appointed to fill in the construction diary and record the daily construction situation in detail, so as to facilitate the contact before and after the project. All kinds of construction technical data and the progress of the project are carried out at the same time, sorted by category, and loaded into the information kit respectively, which lays the foundation for the accurate, fast and neat completion acceptance data.

4. Grasp the construction market information and strengthen the project cost control

With the rapid development of modern scientific management methods, the project manager must fully understand and understand the new materials and trends in the construction market at home and abroad. First, based on the construction drawing, carry out quantity analysis and make a lot of market research to prevent unqualified products from entering the market. If the quality of materials does not meet the requirements, the engineering quality will not meet the standards. Therefore, strengthening the quality control of materials is an important guarantee to improve the engineering quality and a prerequisite to create normal construction conditions. The project manager must master the market conditions of materials, as well as the information on quality, price and supply capacity of materials, urge the materials to purchase, open up the channels for purchasing materials, shop around, try to purchase goods directly from manufacturers, minimize intermediate links, scientifically organize the procurement, processing, transportation and storage of materials, establish a strict planning and scheduling system, implement unified adjustment of materials among projects, and accelerate the turnover of materials funds to ensure normal construction. For the main materials of the project, there must be a formal factory certificate and inspection report when entering the site. Reinforced concrete and prestressed concrete members shall be sampled and inspected as required. Due to transportation, installation and other reasons, the quality problems of components should be analyzed and studied, and they can be used only after being processed and signed. All products and components with unclear marks or quality problems, and general materials with doubts about quality assurance information or inconsistent with the contract provisions shall be sampled. For imported materials, equipment or materials used in key parts, such as concrete, mortar, waterproof materials, anticorrosive materials, etc., the mixture ratio of materials should be guaranteed, and the trial matching should be done according to the regulations before use. In a word, material control is the basis and premise to ensure quality.

5. Take measures to protect the construction machinery.

The control of machinery includes the control of construction machinery and equipment and tool fees. According to different process characteristics and technical requirements, appropriate mechanical equipment should be selected. To use, manage and maintain machinery and equipment correctly, it is necessary to improve the "man-machine fixation system", "operation certificate system", "post responsibility system", "safe use system" and "handover system" to ensure that machinery and equipment are in the best use state.

in the construction of the "Suifu Primary School" project, the company adopted a simple and practical "Star Tile" as the canopy roof for the protection of machinery, and all kinds of machinery and equipment in this site, such as mortar machines, are equipped with one roof for each machine, each with its own number. As the roof of the rain shelter is made of star tiles, the skeleton is made of 1 inch steel pipes and fittings, and the star tiles are tied with iron wires, which is convenient for installation, disassembly and use, beautiful and practical, and can be used for many times. During construction, the line of sight is good, occupying little space on the construction site, being rain-proof and wind-proof, and ensuring safe production.

6 Strengthen the control of the construction process and improve the engineering quality

Excellent engineering quality is directly produced in the construction process. The builder and quality controller of the project department must inspect and supervise the construction operation process of the operation team, including operation methods and operation processes, so as to eliminate quality problems in the bud to the maximum extent. Before entering the stage of rough decoration of civil works, the team leader should be required to make a model or a model wall first, and then start construction on a large scale after the model acceptance reaches the expected effect. In the future, the acceptance of the team's work quality will take the model made by himself as the physical standard.

before entering the main project, please ask the construction unit to decide the varieties and specifications of the external wall tile as soon as possible, so as to calculate and set out the positioning according to the specifications and dimensions of the tile during masonry and determine the position of the aluminum window opening. At the same time, the construction sequence of exterior wall facing can be adjusted according to the construction requirements. And assist the team to carry out model construction on the first floor external wall, so as to ensure that the paving tiles are neat, the apron slope of the window sill is uniform, the specifications of the eagle mouth are consistent, the lines and joints are horizontal and vertical, and the engineering quality is improved.
