| As China's economic growth, infrastructure investment increased rapidly, driving the construction boom, construction quality is gaining attention. Pros and cons of building quality, not only to the applicability of the project, but also related to the safety of life and property, so in construction projects, enhance project construction quality management to ensure construction quality and safety of people's lives and property is construction companies priority.Based on the construction phase of the project quality control, analysis of the factors that affect the quality of the project to explore the dynamic quality control to ensure the quality of people's work process quality, and promote the quality, emphasis on building construction site and construction quality assurance system unit (enterprises) quality management.Paper first analyzes the company's assembly plant dawn of central air-conditioning projects under construction, and construction quality of the factors affecting the analysis; Secondly, elaborated on the work of the construction project quality control of content, proposed to strengthen quality control of construction methods;Third, comparative analysis of the assembly plant quality installation of central air-conditioning factors, and pointed out the construction project quality is a problem; last clearly dawn to assemble the installation of central air conditioning plant construction quality control methods and measures.Central air conditioning works as a construction project, a branch of construction with different characteristics, so quality control programs and quality control processes have some differences with the construction. Therefore, this article Shenyang Liming Aero Engine Group, the new assembly plant repair of central air-conditioning projects, for example, on the central air conditioning project implementation stage of quality control were discussed. Company assembly plant in Shenyang Liming is converted by the state investment R & D base for military aircraft engines, Dadong District, Shenyang is located in the East Tower Street, a state key projects. Dawn assembly plant by the company's main plant and the South Annex, composed of three parts. Main plant high cross-section elevation of 10 meters bottom chords of roof trusses, roof truss bottom chords of low cross-section elevation of 8 meters, South Annex for the three-storey brick structure, North Annex, for the two-story brick structure, with a total construction area of 13,570 square meters, all air-conditioned area.This first chapter was the first dawn to assemble an overview of the installation of central air-conditioning plant, and to investigate the current quality of the installation of common problems and how to identify the quality control points.In the second chapter of the installation of central air conditioner assembly plant quality factors were analyzed, mainly from the construction plan, construction processes, materials procurement and construction unit Jige aspects of quality influencing factors. (1)construction program is right or not, directly affect the project quality control can be smoothly achieved. Often due to poor planning and delays in construction progress of the program, affecting the quality, increase investment. To this end, the construction program development, selection, need to combine engineering, technical, managerial, technical, organizational, operational, economic and other aspects of comprehensive analysis, considering, seeks construction method technically feasible and economically reasonable, advanced technology, and effective measures,easy to operate, helping improve the quality, speed up the progress and reduce costs.(2) Central Air Conditioning Project civil construction which begins after the main project, the main civil construction quality of the installation of a direct impact on construction quality, ventilation and air conditioning engineering and civil cooperation and other professional works, such as piping, electrical and interior decoration decoration engineering co-ordination are closely related. (3)material factors that affect the quality of renovation work, another important factor. Materials, including raw materials, finished products, semi-finished products and structural pieces and parts is the material of construction, should focus our attention on the following areas:control material information, and good material supply planning, supply and use reasonable organizational materials, bulk materials can organize the tender selection suppliers, transport and laying is possible to avoid damage and secondary mouse transport, good material out of storage and warehouse storage materials and acceptance of work, attention to certificate of inspection and collection.Chapter III of this project is how to carry out quality control during construction, construction units from the tender selection, construction and project management qualification to the eligibility conditions, the project quality control organization and staffing and the construction quality of the reporting system of major units and so discussion of how the personnel management from the construction unit and the system setting to good quality. Chapter Four dawn installation of central air conditioning assembly plant construction quality control methods and measures, consists of the construction preparation phase, construction phase of the construction, delivery of the final acceptance phase of the project quality control, re-warranty the four stages of project quality control process.(1)before the technical preparations for construction work includes:construction of technical information prepared for the construction site and operating environment of the technical preparation, construction drawings and technical disclosure of joint trials, preparation of construction organization design, unit construction organization design and construction programs, projects, construction workers Thequalification, technical disclosure, and construction safety technical disclosure, the preparation of engineering equipment and materials, construction equipment and testing apparatus Xu Yong plans. (2) the management of the construction process, including:guidance and supervision of construction, process design changes, materials or equipment changes to procedures, changes due to construction conditions modified the original construction technology programs, guidance and handle new technology work on the commissioning and commissioning program, participate in quality incidents, security incident handling and timely complete the technical log and so on. (3)pay the final acceptance of technology management including:collection, compilation and collation of engineering data, mapping built drawings, completion of the project proposal submitted to participate in the work, to participate in completion of all documents submitted for inspection, sorting and preparation of project files, prepare engineering Summary of Construction Technology and so on.(4) Upon completion of final acceptance and delivery of house, the works would enter the maintenance phase.This phase is the last link of project management, but the mechanical and electrical equipment installation units, this is the real test of effectiveness of quality and installation time.Continued stay in the small owners, the system gradually under full load operation, if the quality of project risks will be gradually exposed. To ensure that all systems work and the completion of maintenance tasks, mechanical and electrical equipment installed after the completion of units will normally be left at the scene a few people, they will be building the company with property maintenance of electrical and mechanical systems.This is also a non-small-business labor costs for overhead. Therefore, after completion of project management should be to minimize costs and develop new profit growth point.In short, this paper how to do quality control of central air-conditioning installation works were analyzed, in particular, yes right now the various elements of management and quality control problems and Ying taken measure were penetrate deeply on this. Research focus is the quality of the whole process of construction project management and objective control, therefore, wish to take this paper can Construction Enterprise of the project manager Zai Mian Dui complex engineering project management theory and Shijicaozuo when some inspiration in to enhance the efficiency of project management project manager. |
