1 Introduction
Building the product, but not identical products in general, because not only the construction quality is good or bad impact to the construction business, building long-term development units, but also directly related to the safety of human life, but in recent years due to the construction market management confusion and other reasons , resulting in some construction projects can not be in accordance with design drawings, construction, quality of construction can not meet the relevant technical specifications, resulting in a large number of building serious quality problems, especially earthquake and other natural disasters after the construction of quality breaks out, a considerable part of building appeared cracking, collapse, resulting in significant economic losses and casualties, so this stage must step up construction of the construction quality management, virtually eliminating quality problems, ensure quality.

2 impact factor Construction Quality
Affect the building construction quality of many factors, including structural design, building materials, machinery and equipment, site environment, construction Technology and management system.

2.1 Structural Design
In order to jump on the bandwagon, seeking new, many construction projects only concerned about the structural design of external appearance, resulting in structural discontinuity reasonable and convenient construction.

2.2 Building materials
Civil works used in the cement, sand, stone, wood, metal, asphalt, synthetic resins, plastics and other materials collectively referred to as, the quality of construction materials is the basis of a direct impact on construction quality is good or bad.

2.3 Equipment
Normal wear and tear or mechanical equipment failures, do not follow the rules of operation, precision control instrument failure detection equipment, will lead to systemic factors, the quality of the mutation, resulting in the quality of construction accidents.

2.4 site environment
Construction site and the surrounding geological conditions, climate and environment referred to as the construction site environment impact of building site environment is an important factor in the quality of construction. In general site environment with complex and changing characteristics, such as the million dry weather conditions to change, temperature, humidity, wind, rain, heat, cold have a direct impact on construction quality.

2.5 Construction Process
Construction process is to determine the key to good or bad quality of the project, different construction techniques will lead to construction works of a different quality of construction, general, advanced, rational, standardized system to improve the construction process will not be accidental or unexpected quality problem, and can speed up the schedule and reduce costs.

2.6 Management system
Management system or a direct impact on improving the quality of building construction quality, strict management system for the construction to ensure construction quality, speed up the construction schedule, cost is critical.

3 Construction Quality management principles
To ensure improved quality of building construction, must adhere to and follow a specific construction quality management principles, using a range of detection, surveillance and control measures, means and methods to ensure that construction projects meet contract specifications required quality standards.

3.1 "quality first, customer first" principle
In the current competitive construction market, construction companies wishing invincible, we must adhere to the "quality first, customer first," the basic principle. The quality of construction works the first place, the time for building the user lives and property considerations.

3.2 prevention, pre-control-based concept Construction
Construction units in the construction process, to establish prevention, pre-control-based construction concept. Will be considered after the check and adjust the focus to advance in the prevention, control things, to avoid unexpected accidents. To adhere to the prevention, strengthen the material quality of the construction process, site environmental monitoring and inspection.

3.3 scientific, fair, law-abiding professional ethics
Whether it is the management of construction enterprises, construction unit of the technical staff or construction workers, supervisors or supervision units in the building construction quality management process, should be strictly in accordance with the relevant technical specifications, the objective reality from the project , dedication, respect for science, discipline, strict self-discipline, holds scientific and impartial attitude and work ethic, do a good job building construction quality management.

4 construction quality management measures
4.1 Management of construction materials
For the management of building materials, to establish management accounting, for sending and receiving, storage, transportation and other aspects of Technology management. The first task is the source of the material control the selection with solid professional knowledge, ability to identify high quality hair procurement personnel responsible for procurement of various construction materials, so that more material manufacturers to master all the details, while also doing on-site management of construction materials. advance arrangements for transport planning and routing of materials, when the materials to the construction site, to strengthen the inspection and acceptance of work, to avoid mixing and the use of substandard materials engineering in the construction process, but also make building materials, storage, improve the site temporary storage of water, moisture-proof function.

4.2 Machinery and equipment management
Machinery and equipment management, basic tasks are: reasonable equipment, safe use, service production in order to ensure the quality, speed up the construction progress, improve production efficiency, to take to create good economic conditions to improve the management of mechanical equipment, basic principles: respect for science, standardized management, safety first, prevention in the construction process according to the different process characteristics and technical requirements, select the appropriate machinery and equipment, and ensure the correct use of machinery and equipment, management and good maintenance. while strengthening the management of machinery and equipment, operator's management, will be equipped with adequate staff (operators, commanders and maintenance personnel, implement the "Who uses, who manage" principle, a sound licensing system, inspection system and other mechanical equipment and do routine maintenance, minor repairs, repair and other maintenance work, prohibited ill operation.

4.3 site environmental management
Good architectural design and site planning, the implementation of closed construction site entrances and exits should be hardened and ground to keep the surrounding clean. But also the implementation of sanitation management responsibility system, the construction engineering and construction units should be timely removal and transportation of construction waste generated during construction to prevent environmental pollution, and construction waste shall not be handed over to individuals or non-approved waste transport unit in the building process.

4.4 Construction Process Management
For construction projects, which must be strictly according to the project, carry out construction design, choose a reasonable construction of technical measures, the construction plan, construction techniques, etc. do a good job project preparation work, the preparation of practical construction organization design for different projects characteristics, to develop appropriate implementation plan, and the organization of technological innovation, so as to ensure the feasibility and advanced construction Technology for a number of technical problems, the processing operations to develop practical programs to achieve in ensuring the quality of the project under the premise that speed up the construction schedule and reduce construction costs.

4.5 improve and implement the management system
Construction to improve construction site management, construction site management to promote scientific, standardized and systematic, according to the needs of Industry and engineering practice, well-developed construction quality management system, such as the construction site appraisal system, regular system, file management system, warehouse management system, safety management systems, temporary power management systems, security management systems, fire management system, the project manager must be construction workers and construction team for every process of technical quality of tests, good materials, preparation, construction techniques, quality requirements and inspection methods, common problems and preventive measures. project construction must firmly grasp the project's construction process and technical quality requirements.

5 Conclusion
Project quality management is the core of the construction management activities throughout the entire process of construction management, project quality management is directly related to the effectiveness of their quality construction, so for the huge investment, cost of labor, materials, energy and more construction projects, Only by improving the quality of management, strictly control the construction quality of construction, in order to effectively ensure the quality of building construction, to ensure that people's lives and property.
