On housing construction in construction quality management

[Abstract] the modern stage of social Development, housing construction in the growing number of these requirements for the Engineering and construction of more stringent. The construction part of the process is to construct a building entity, product quality has a decisive role. For the continuous improvement of housing construction projects the quality of the construction phase will need to attach great importance to the quality of management response to these, this paper focuses on analysis of housing construction in construction quality management related issues.

[Keywords] housing construction, construction quality management, measures

Development of economic globalization, China's market economy has created a huge room for improvement, in this context, the modernization of our society continues to accelerate the pace of urban living standards higher figures 我国 quality of construction also increased rapidly in the construction sectors in Engineering units subject to many factors, resulting in housing construction projects is a different quality, serious harm will indirectly to the building structure and the use of security features, for example: concrete floor void, cracking, peeling, sand, kitchen , roof, leaking and serious, more serious construction differential settlement, there will be the responsibility of the overall collapse of these issues gave the normal life of residents of potential problems, a direct impact on the safety of people living level which, according to the specific circumstances of housing construction, implementation of project quality management is indispensable work.

1 lead to problems in housing construction factors
According to the survey, 21.2 percent of China's construction of various quality problems exist, which not only increased the project cost, housing construction will also affect the use of functions, while housing construction for quality problems that exist in the analysis, obtained leading to the quality standards of many factors. the main responsibilities of parties involved in construction can not perform their duties in accordance with the provisions of all the various aspects of management in place is leading to major aspects of the problem.

1.1 Cost factors
Many units in order to reduce construction costs continue to curb investment costs, but often over-down project cost would be counterproductive. The quality of housing projects with a direct link the size of the project cost, project cost too little will cause great work construction side pressure , the construction enterprises to financial constraints and difficult to buy high-quality construction materials, work in the management of not fully in place. Housing construction, its material costs consume a large proportion of the project investment is too small to use materials directly affect the quality, performance, lack of these programs will impact the construction of the back addition, the construction schedule will also be project cost barriers, lack of adequate housing of construction workers has led to the construction work is not smooth and extended duration.

1.2 Design factors
Architectural design to the back of housing construction operations guide, which is operating in an orderly manner to ensure project basis roof waterproof design, often observed with a parapet of the roof eaves height of the pan of water there is not enough local issues, design expansion joints a roof top of the wall pressure when properly arranged, these are part of the design problems caused by the addition, some kitchen and bathroom design to the hollow floor, not taking into account the water layer down the water pipes through the floor plus casing design, the leakage to the Housing bring risks for the design of the ground floor is designed to use more traditional methods, precast hollow screed plate and then for the first wipe the surface layer, in which case the construction work then he will bring the ground and ceiling crack.

1.3 Construction Factors
Affect the quality of housing construction during the construction of an important period, the construction of factors leading to substandard quality of housing construction reflected in the number of cover. Construction of the operator's skill level directly affects the quality of housing construction works, the current number of Engineering units in the adoption of the lack of strict personnel assessment system. Most construction workers do not participate in professional training or professional skills to obtain employment certificates are posts, which housing construction is difficult to guarantee the quality once operations personnel to operate without rules in order to complete the task by then part of the construction can not be guaranteed achieve good quality control results, especially a lot of professional training has not been involved in construction of migrant workers, from construction operations greatly reduce the level of team work.

On the other hand, the lack of construction in the construction of sound quality control system, construction methods, operation of equipment, staffing, operating processes and other issues gave the project quality and security. Before the procedure difficult to achieve the targets, the latter procedure construction will not deal with problems affecting the quality standards throughout the construction process. Some of the management of chaos Engineering, construction, finished and semi-cluttered site, making the order the destruction of the construction site.

1.4 Supervision factors
Lack of site supervision of construction work led to substandard quality of housing construction is another factor, there is no professional supervision of the construction team will make the problem can not be found in time, inconvenience to the quality inspection work. A small number of units in order to find cost-effective supervisory qualifications to undertake beyond the supervision services, project supervision agency personnel qualifications, and building professionals with a match. Some supervisors undocumented phenomenon of induction, on-site supervision of construction quality control system is not comprehensive, supervisors of materials, components, fittings, equipment, etc. to grasp properly review the environmental, All these have added to the difficulty of project management, while a small number of project supervision in the work without the required inspection and approval procedures for the organization, sub-, division of project quality and acceptance, leading to a lot of quality problems is not to be identified.

1.5 Material factor
Choose what kind of material which I felt the construction, materials inappropriate choice will also affect the quality of housing projects. Example: Selecting varieties of waterproofing asphalt, many aspects will impact the quality of construction to the building, the quality and variety of linoleum, plaster, clay content of sand control, wooden doors and windows to determine the species of wood, which exert a great influence for the quality of the project When the material transported to the construction site, the Engineering units of the organization did not timely review of materials, quality inspection personnel are directly put into use, which affects the material performance of the play, affecting the use of the building from the current situation in the construction industry, due to material and the set of poor quality due to quality defects is particularly prevalent, its impact on the construction quality is also great.

2 to improve the quality of housing construction in the correct measures to Share free download http://www.hi138.com 2.1 to create systems, improve the system
According to the form of housing construction, to establish a good security system, the current construction job management system to be updated to adjust, have helped improve the quality of the project. Construction unit in order to achieve improved quality of the project, the indicators must be combined with modern architecture system, and actively updated construction regulations. specific operations can refer to <<Quality Manual>> This is a programmatic document to set up quality supervision system, while making all aspects of project management project manager, quality manual and procedures to be familiar with documentation requirements, from part of the daily construction operations master project quality, improve the management system, it can carry out the "quality of reward and punishment regulations", "quality analysis system", "quality inspection system", "user visit system" of different policies, different rules only to contents of the implementation into practice, in order to improve people's quality of work means to improve the project entity quality control of construction materials, mainly raw materials, strict construction, precast and other quality control, control of construction equipment, is the right choice, use, management and maintenance good mechanical equipment, methods to control, is the construction plan, construction technology, construction technology, environmental control, mainly on engineering geology, hydrology, meteorology, etc. to understand and master.

2.2 improve the inspection, quality control
In order to prevent construction on the root causes of quality problems, you must check the quality of work to do. Engineering units should pay attention to check the building, arrange for professionals adhere to the "anti-seizure combination of prevention," the full implementation of the principle of "talk, help, anti- , card "scientific inspection strategy, inspection and construction workers just have to adhere to the principle of quality first, the construction process for the next responsible quality control personnel, users, among construction workers should foster team spirit, mutual exchange between cooperation and quality inspection personnel and construction site work and goals are identical, the user should provide high-quality, in order to create a higher quality building products. If the project units in the management of the construction progress and quality of conflict experienced by After usually need to focus on quality management as a so-called contradiction is mainly for the construction of a short construction period, large projects of this situation, the advantage of quality checks engineering managers will ignore this part. Therefore, we must establish a quality control personnel the authority to raise the level of inspection.

2.3 fully prepared to exchange
Do pre-construction housing project preparation to ensure the smooth implementation of foundation construction, housing construction workers should reach the construction site as soon as possible, familiar surroundings, after careful study of engineering drawings, construction layout of the actual situation and make preparations. Met project quality demanding project, the construction party to be organized to visit various projects within the Ministry, and for the quality management system, environmental management system, and extensive exchanges, arranging project related personnel to the scene from the advanced experience in construction, etc. been to each other communication, the unit staff need to sum up the other advantages of the construction unit, reflect on their own inadequacies of construction operations, and take the necessary measures to promptly correct. multi-project-related information collected excellence, the project template response to problems as soon as possible to be resolved soon.

2.4 group research, quality evaluation
Engineering units in order to fully carry out quality control of construction work, construction projects must be to grasp the key to quality control, perform QC group research activities, which improve the physical quality of the construction project a significant effect when the project manager for the Department to be combined with the specific situation is the Development of "QC team management system", the project quality control, quality management as a fundamental consideration, and team-based and widely implemented practices. experienced some quality problems are organizational and technical personnel to participate in the "research-based" activities, will continue to improve the quality of the project to discuss measures for the targets from the achieved results, this can significantly improve the quality of engineering construction project management efficiency. vigorously implement the project quality and quality of the veto system, contracting with the signing of the responsibility of the quality indicators as a way to reject targets. The activities related to the project manager of each employee's vital interests, which improve their quality management to enhance the enthusiasm of help.

2.5 materials, supervision, provision of facilities
In accordance with national targets set for the construction industry documents, to achieve the level of housing construction projects to enhance the quality, engineering teams are following units should be "four Guan", that procurement customs, customs inspection, customs and transportation insurance, use of off, used for the project to overall supervision and inspection of materials, eliminating the use of specifications, models, quality non-conforming materials in housing projects in the implementation of integrated management, mainly for the housing projects to manage all aspects of control one buyer, should not only improve their political identify the level of quality and quality of materials, construction units to choose honest and trustworthy, strong devotion to the buyer, so can the quality of planting materials, and have some knowledge of persons. The second is access to information on the community to investigate the materials industry and timely collection of records of quality, price, availability of information, both to control the quality of materials, but also significantly reduce the material cost investment construction, supervision and construction supervision unit to be developed jointly by the program, a good grasp of all aspects of construction control. Construction project selection of the main materials are professionally reviewed materials to meet the regulatory requirements of the warranty with the book, on the approach of multi-material subject to detection, identification.

3 Conclusion
In summary said, housing construction and people's daily life there is close contact, good or bad quality of the project throughout the construction project of great impact, whether it is engineering units, or construction workers have to be to fully establish the sense of quality, complete the amount of housing construction, while maximizing quality level, which for China's modernization drive is very important.
