How to control the construction quality of decoration and renovation works

Strengthen the building decoration quality control measures

1 Develop quality control program

Decoration projects before the start of work, the implementation of the drawing review system, drawings without review, resolutely not allowed to construction, to do as much as possible to minimize the existence of the drawings of the error, omission, touch, lack of implementation of the quality of the drawings of the joint and several responsibility system, in order to enhance the review of all parties to enhance the sense of responsibility to prevent the review of the drawings of the formalities caused by the changes, rework, affecting the quality of the project. Changes, rework, affecting the quality of the project. According to the commitment of the project bidding documents, the characteristics of the project to prepare the implementation details of the supervision to ensure that the supervision of its own quality assurance system is complete, the system and management structure is sound. It is recommended to implement the sample-led system for each decoration process, and to carry out special technical briefing on various quality problems that are likely to occur in strict accordance with the contents required by the "Handbook for Prevention and Control of Engineering Quality Diseases". Review the construction work instructions of the construction unit and a variety of professional construction programs, from the source, from the system to standardize the operation of the sample lead. Decoration project based on the project construction drawings sub-specialty, sub-unit, listed sample sub-projects, clear sample implementation location, parts, time, acceptance criteria, do a good job in each sample room, such as: masonry sample room, plastering sample room, brick veneer sample room, windows and doors sample room, ceiling sample room, and so on, and then only after a point with the surface of the spread of operations.

2 strict control of the quality of materials

Decoration materials is an important material basis for renovation projects, the correct choice and use of decoration materials, is to ensure the quality of the project is one of the important conditions. Because of China's current building materials market management is not strict, a lot of decoration materials do not meet the national and industry standards. In emphasizing the concept of environmental protection and sustainable development, the main decoration materials should be monitored by the group *** with the gatekeeper to strengthen the material inspection and acceptance through the bidding of preferred manufacturers to ensure that priority is given to the use of good quality, low price, non-polluting decoration materials. Renovation of the main materials in the specifications, varieties and environmental protection to meet the requirements of the design drawings and construction specifications, in particular, to meet the national standard "Indoor Environmental Pollution Control Specifications for Civil Buildings" requirements, the use of materials to meet the green environmental standards. Project decoration process should be strictly in accordance with the drawing review and technical briefing of the relevant records for construction. Construction process is strictly prohibited unauthorized changes in design, especially in the use of decoration materials without permission is not allowed to replace. In case of design changes must be made through the written form of written application after review and report construction, design and other relevant parties to sign the approval before the change.

3 optimize the quality control of the construction process

The construction process of the building renovation project is composed of a series of interrelated and mutually constraining processes. The quality of the work process is the foundation, which directly affects the overall quality of the project. Therefore, to control the construction quality of the project, the first must control the quality of the process. To strictly comply with the process regulations, construction process regulations are the basis for construction operations and regulations, is to ensure that the quality of the process of the premise, everyone must be strictly enforced, shall not be violated; active control of the quality of the process activity conditions. Must strengthen the quality inspection work, the quality of the status of comprehensive statistical analysis, timely grasp of the quality of dynamic. Once found that the quality of the problem, immediately study and deal with, from beginning to end so that the quality of the effect of the process activities to meet the norms and standards; set the process quality control points. In order to ensure the quality of the process to control the focus or key parts, or weak links, in order to strengthen the management in a certain period of time, under certain conditions, so that the process is in a good state of control. At the same time set up quality control points. First of all, the construction of the project object to take a comprehensive analysis, comparison, in order to clarify the quality control points. Then further analyze the quality control points set up in the construction of quality problems that may arise or cause hidden quality problems, for hidden causes, accordingly proposed countermeasures, measures to be prevented. Setting up quality control points is a powerful measure to pre-control the quality of the project. According to the characteristics of the project, importance, precision, quality standards and requirements, may be a complex structure of a project, may be technically demanding, construction difficulty of a structural component or item, branch project, may also affect the quality of the key to a certain link in a certain process or a number of processes.

4 dynamic monitoring

Omni-directional inspection of construction quality should be timely on the construction of parts or processes for regular inspection or dynamic monitoring, found that the problem is handled in a timely manner. Dynamic monitoring of the site has a variety of methods, summarized in the main "visual method, measurement method and experimental method" three. "Visual inspection method" is to take "look, touch, knock, light" to carry out quality inspection methods, of which "look" is based on quality standards for visual inspection of the appearance, such as internal wall plastering surface and The "look" is based on quality standards for visual inspection of the appearance, such as the internal wall plaster surface and yin and yang corners are straight, whether the ground is smooth and flat, etc.: "touch" is to carry out a feel check, such as whether the paint has fallen powder, cement walls, the ground is sandy, etc.: "knock" is the use of detection tools to carry out a sound check; through the sound of the virtual reality, clear and dull To judge the quality of decoration: "light" is for hard to see or dark parts. Mirror or light to check. "Measurement method" is through the use of relevant testing instruments. With on-site measured data and relevant specification data relative to the quality inspection method. "Test method" is to take the experimental test means to carry out quality inspection methods. The hidden works and the project of handover between processes should be checked and accepted in time. Without inspection and acceptance of the process shall not be hidden. Quality acceptance of concealed works and sub-projects construction unit must be qualified in the self-check before applying for acceptance.

5 Strengthen the quality control of the indoor decoration environment

In addition to the above mentioned selection of green materials, at the same time from the construction of various process aspects of manpower, the development of specific environmental management programs, and incorporated into the project construction organization design. Try to choose non-toxic, low-toxic, non-polluting, less polluting construction process. For example, minimize on-site production of furniture, modeling doors, sets of mouth, etc., and promote the use of paint-free panels and molding furniture panels. The promotion of the use of paint-free panels can reduce the site spraying construction pollution, the use of molded furniture panels can reduce the amount of adhesive. If the building interior decoration, when repeated use of the same design for many times, it is advisable to do a good sample room, and its indoor environment pollutant concentration test. Sample room indoor environmental pollutant concentration testing methods should be consistent with the provisions of the relevant norms, when the test results do not meet the norms, should find the reasons and take effective measures to deal with.

6 Strengthen the design, construction personnel training

Decoration project construction is wide, involving many processes, high quality requirements; coupled with the decoration industry is a new industry, not only the professional construction personnel, and professional designers are more scarce. Therefore, to strengthen the design and construction personnel business training is the basis for improving the quality of decoration projects. However, at present, the business quality of technicians in China's decoration engineering industry is low, and most of the technicians are separated from civil engineering, they are groping for experience in practice, gradually maturing in failure, and there are very few decoration professionals. It can be seen, higher education should accelerate the training of decoration professionals, decoration enterprises to take multi-level, multi-channel, multi-form training, is a fundamental way to improve the quality of the decoration team.

In short, the solution to the quality of construction projects is not easy, but a systematic project, must be based on the characteristics of the various divisions of the project, and work together, in order to complete the construction task on time, quality and quantity.
