How to strengthen the quality management of the construction phase

1. Strengthen training, enhance the awareness of safe production

Strengthen the pre-service and on-the-job training to ensure that each on-the-job workers, are proficient in the necessary safety production skills and operating norms. The old saying goes: "The best way to get the most out of your life is to get the most out of your life. Sharpening the knife is not a mistake? To adhere to the people-oriented concept of scientific development, resolutely overcome with? Sickness? The phenomenon of on duty, put an end to the pursuit of unsafe production benefits of quick success and quick profit behavior, to do? Rather stop for three minutes, not a second? Safety training can not be achieved overnight, it is not possible to do all the work at one time, according to the development of the enterprise 's needs, according to the needs of the workforce changes, through the combination of sending out and inviting in, off-the-job rotational training and job training, regular training and certification training, corporate training and institutional training, centralized training and decentralized training combined with a variety of ways to carry out the whole person, the whole process of training, so that The company's main goal is to provide the best quality of service to its customers, and to ensure the safety of its customers.

2. Quality monitoring prior prevention, construction operations prior guidance

2.1 The quality of raw materials and semi-finished products required for the project to check and control

First of all, the construction unit is required to strengthen the management of the staffing, organization and management, testing procedures, methods and means of various aspects, clear on the material The quality requirements and technical standards of the materials are clear. For steel, cement and other materials, multi-head, multi-channel, each batch of steel, cement to do? Double control (i.e., there should be a warranty, certificate of conformity, but also material retest report), untested materials are not allowed to be used in the project, the quality of the material does not meet the requirements, and timely invitation to withdraw from the field. In a company workshop power distribution room renovation project, completed soon after the leakage, the original design of concrete for the C25, the rebound test, concrete strength has not reached the CIO. after investigation, it is due to unqualified cement.

2.2 Strengthen the quality consciousness, the implementation of? Three inspections?

Before the construction of the project, the site management personnel held by the construction unit of technical personnel, quality supervisors and the relevant engineering team leader quality meeting to strengthen the awareness of quality management, clear in the construction process, each process must be implemented? Three inspections? System, and the company's quality supervision department full-time quality inspector signature acceptance. Then by the management acceptance, signing recognized before the construction of the next process. If the construction unit does not carry out? Three inspections? or full-time quality inspector signature, the site personnel refused to acceptance. In addition, on-site personnel in the construction site using patrol, parallel inspection, follow the side monitor, random sampling methods, to be carried out by the construction unit? Three inspections? After further acceptance, completely eliminate quality problems in the project.

2.3 Strictly sign the acceptance of the hidden works, found that the quality of hidden problems to the construction unit to rectify

In the hidden works acceptance, first of all, the construction unit required to self-check qualified, and then by the company's quality inspection personnel to approve the grade and sign, and fill in the acceptance form to submit to the site management personnel. Then the site management personnel by the organization of the construction unit project professional quality (technical) responsible person for acceptance. On-site inspection and review of raw materials to ensure that the information is complete, certificate of conformity, test reports are complete, the elevation of each layer, the axis of the knot should also be checked layer by layer, strict acceptance. Require the construction unit quality inspector signature can not just a formality, to really go to the inspection and acceptance, and then checked by the supervisory party. Supervisors found that the problem of timely written notice to the construction unit, can not be verbal, to be treated by the construction unit or rework after the completion, but also re-inspection, strict inspection, quality assurance.

3. Dynamic control, check carefully during the incident

Quality control in the process of construction, is the important difference between the site management and quality supervision department. Comrades who do not know much about the project management work tend to think that the site management is just a turn at the scene, take a look, acceptance check whether the project is in accordance with the drawings, specifications, standards for construction. This often makes some quality problems have appeared, and even rework. In the quality control to change the static inspection into dynamic control. Mainly grasp the following aspects:

3.1 Strengthen the management efforts, 24 hours a day side monitoring

For each site management personnel required to do? Five diligence? : that is, eye hard, often to the site to understand the construction situation, more construction drawings, familiar with the design of which are important parts; hand hard, found that the problem is often a record, to deal with which problems to have a record; leg hard, often to the site turn; mouth hard, for the construction team is often prone to quality hazards to often remind the construction team often to the bottom of; brain hard, familiar with the drawings, the brain to think of measures to ensure the quality of the project. In the way of work, the depth of the requirements to do? Strict? (Strictly according to the construction specification requirements for construction, strict inspection and control),? Quasi? (dealing with the problem to be decisive, accurate, to speak based on data),? Fine? River work carefully, self-care things to be meticulous),? Real? (to do a thing to be practical, personally to do, to check, encounter quality problems to do substantive processing, can not find reasons to shirk, to solve substantive technical problems for the construction unit, the construction unit). For important parts or special process requirements of the parts of the construction process, supervision engineers shall be 24 hours a day, 24 hours with the side supervision, found that the problem is dealt with in a timely manner. Trial block extraction, production is in line with the requirements, and even personally take samples; supervise the measurement of the material on the table after the material, whether the operation of the workers in line with the standard. Found quality problems, timely notification of the construction team to rectify, eliminate quality hazards.

3.2 works in the grasp? First? ,? Key? ,? Critical? Project

According to the scale of the project, engineering characteristics and technical requirements, from the actual need to determine the site personnel to manage the project. When the construction site pouring the first frame column, tying the first beam reinforcement, masonry, painting the first wall, tying the first column, beam reinforcement, support the first column mold, the site management personnel to go to the site to check, review the axis and elevation, measurement of components, dimensions of the structure, weighing the weight of the materials with the weight of the project key parts, such as the frame beam-column nodes, overhanging structures, structural staggering of the elevation, deviation from the axis, etc., should be carefully checked. For the key parts of the project, such as frame beam and column nodes, overhanging structures, structural fault elevation, off-axis, etc., the parts should be carefully inspected and accepted in strict accordance with construction specifications and design requirements. For the critical projects, the construction team is required to carry out? Three inspection system?

3.3 site inspection, measurement check, data speak

Site management personnel through site inspections, field measurement results and data to check and judge the quality of the project to the measured data to assess the quality level. Such as axis, elevation error, axis bias how much, elevation low or high; rebar binding less than a few, specification binding error how many, silicon pouring after the honeycomb, holes in how many, how big the honeycomb, how deep the holes, in what parts and so on. Advance written notice to the construction unit and attached to the measured data, so that the construction unit for the quality of the problem can not be covered up, can not be dealt with sloppily, to avoid similar quality problems in the future.

4. Implementation of design changes

In the construction process, design changes are unavoidable, the site management should take the lead in contacting the design unit for design changes, design changes in a timely manner to be distributed to the construction unit in different categories, and supervise the implementation of construction.

5. Acceptance after the fact, timely treatment of quality problems

When the sub-item, branch project or single project construction is completed, we timely according to the corresponding construction quality acceptance standards and methods, the quality of the completed project acceptance.

The last remedial measure in quality control is the after-acceptance. Through the after-acceptance of the construction of quality defects or major quality hazards, through the project manager to issue a timely suspension of the project order, requiring the construction unit to stop work to rectify. And with the relevant units in a timely manner to put forward a solution to the program, the problem will be dealt with. So as to achieve both ensure the quality of the project without affecting the progress of the project, to avoid unnecessary economic losses.

For the important divisions of the project with the process according to the existence of construction technology and operational requirements to draw a flow chart, such as pouring columns, beams and slabs of silicon flow charts, marking the construction sequence, to facilitate the acceptance of the quality of accidents occurring when the cause of the analysis. Produces the quality accident or the aftermath problem, the site management personnel only to the quality problem to deal with the substance, puts forward the reasonable and feasible processing opinion or the program in time, but does not go to emphasize the cause of the responsibility of the accident. This makes the construction unit and construction personnel are willing to approach the site management personnel, not taboo, timely exposure of the site management personnel to ignore the place, and the site management personnel to work closely with the *** with the improvement of the quality of the project.

Through on-site management, grasp the above mentioned several links, the construction phase of quality control, can effectively improve the quality of the project, for the company to reduce costs and improve efficiency.
