CONSTRUCTION PROJECT QUALITY MANAGEMENTWith the development of our national economy, the construction industry has been moving in the direction of diversification development, the construction industry in China's economic development plays a very important role. Construction project management is directly related to the project quality, cost management, personnel security, business efficiency, matter to an enterprise even of vital importance, but our country architectural engineering management at present there exist many deficiencies: management system is not perfect. Most of our construction in order to save personnel expenses, reduce construction engineering administration personnel quantity and quality. Management system development of. Construction industry management system are from some famous construction industry experts to jointly study the development, but in the construction units in just a piece of paper, and they are just to cope with the higher level examination, and cannot be applied to construction project management.In our construction management, to establish a comprehensive project of our country construction management system, mainly because of a lack of management theory and experience in china. Establishment of construction project management system is a specialized and professional issues, its implementation must by the senior building subject experts and has extensive experience in management to organize, the only way to achieve. Foreign construction industry in both technology and theory are more advanced, so our country in construction project management system in establishing a procedure, must draw lessons from foreign advanced concept, in addition, also must absorb the advanced project management method, and information on all aspects of the comprehensive and integral. In short, to ensure that our construction management is orderly undertake, must be in sound engineering management system as construction overall management level of the underlying securityStrengthen the construction of quality management, establishing the quality assurance system, the quality of Engineering work. Engineering construction enterprise according to the quality assurance system, form effective quality assurance system, establish the quality policy, so as to make it more prescriptive, systematization and maneuverability. To be human, material and machinery of various elements of an effective combination of. First of all, one is to control the quality of the core, take them as the control force, fully mobilize the enthusiasmof people, establish quality first concept. Secondly, construction materials building as the main product, the material quality control is the key of project quality control. Finally, construction machinery and construction mechanization is the main mark of modernization, plays an indispensable role in project construction, which directly affects the construction project progress and quality, therefore, select and use of construction machinery equipment is very important. So, should the specific characteristic according to project project, a comprehensive consideration of various factors, the implementation of effective control of the construction site, in order to ensure the construction quality and safety and create good external conditions.At this stage of construction project management has been paid more and more attention, project cost management is project management indispensable content. Project management essential characteristic can be reflected by the project cost management. First, establish project cost management responsibility system. Project management cost responsibility, unlike the responsibility, responsibility is not equal to the cost responsibility complete complete. At the completion of work responsibility at the same time, should also consider the cost responsibility implementation, further clarify the responsibility cost management, make every manager has cost management consciousness, so be very careful in reckoning. Secondly, the construction team to execute subcontract cost control. Project department and construction team is established between specific labor contract relationship, project department have the right to the construction team schedule, quality, safety and site management standard of supervision and management, at the same time according to the contract to pay service charges. Once again, teams of construction cost control, the construction team management, project department should not intervene too much.In order to ensure the government supervision effectiveness and authority, should improve the overall quality of the supervision team. Therefore, strengthening the construction of quality supervision of construction quality management study, so that the supervision and professional qualities. In addition, quality supervision means also to continue to improve, increase the detection equipment, make supervision work has greatly the content of science and technology, to realize the modernization of supervision work. From theconstruction of the overall market, market operation rule is not perfect. Lax enforcement of the law, the phenomenon of impunity will often appear. Project quality risk is largely due to the construction market confusion caused by. Therefore, the government must establish and improve the operating rules, these rules can really implement service guarantee.Any construction projects and other construction projects recently, in size, degree of technical complexity, or engineering properties may have many differences, but the project management has a lot in common. In the current fierce competition in the market, some engineering company in maintaining and developing the original market areas can also continue to develop and adapt to the new market. In the competition continue to grow and develop, while others stagnate before, continued to shrink, and even exit the market decline, the reason is not built up a set of advanced, scientific. Agile project management mechanism.Effects of many factors on the quality of construction projects, such as building structure mismatch, tilt, collapse, destruction, crack, seepage, water leakage, poor rigidity, strength is insufficient, section size is accurate, however, investigate its reason, can be summarized as follows:( 1) against the building program. If not through feasibility argumentation, make investigation on decided yet; not clear engineering geology, hydrology geology brash start; undocumented design; without any modifications to the design, construction; not according to the drawings; the completion of the project is to test running, without acceptance on delivery of some phenomenon, cause many project save the serious hidden danger, house collapse accidents have also occurred.Engineering geological investigation of reason ( 2 ). Not serious geological investigation, provide geological data, data error. Geological exploration, borehole spacing is too big, can not fully reflect the actual situation foundation, such as when the bedrock surface fluctuation is large, soft soil lay er thickness is also very big; geological exploration drilling depth is not enough, did not find underground soft soil, landslide, grave, hole formation; geological survey report in detail, such as inaccurate, will lead to the error based scheme, caused by the uneven settlement of foundation, instability, the upper structure and wall crack,damage, collapse.( 3) without reinforcement treatment of foundation. On the weak soil, dredger fill, miscellaneous soil, collapsible loess, expansive soil, rock outcropping, lava, soil hole uneven foundation reinforcement treatment or not handled properly, that led to the great cause of quality problems. According to different characteristics of foundation engineering, foundation treatment should be in accordance with the superstructure and combination, make its work principle, from the foundation treatment measures, design, structural measures, waterproof measures, construction measures considering management.( 4 ) design calculation problem. Inadequate design, structure unreasonable, the calculation sketch is not correct, computational load is too small, internal force analysis is incorrect, settlement joint and the expansion joint is arranged properly, the overhanging structure without overturning inspection, are induced by the quality problems. Such as a retaining wall engineering design without a clear understanding of the engineering geological conditions, construction and not on site verification, coupled with the construction team in the foundation excavation of the site geological conditions failed to timely feedback to the design staff, therefore, although the upper structure design, the construction of good quality, but the basic design is not reasonable, so that the use of design value of load has not yet reached the half, retaining wall appeared to slip and fall. Another example of a silo cracking accident, but also because design personnel negligence, in the pilot when Jian Bi crack, cause construction completion can not meet the basic requirements for the use of.Project management measures. 1 must be built and perfect engineering management responsibility system, make clear a key, fulfil responsibilityThe establishment and improvement of project management responsibility system, engineering management is smooth, responsibility is clear, whether the operation is effective, is to strengthen project management must first solve the problem. Salaried qualification standard limit, such as seventeen bureau of China railway construction enterprises, in the future for quite a period, the survival and development of the field of railway, highway, located in the municipalengineering construction market, the enterprise must do the business strong, do well the project, enhance core competitiveness. The company changes after making, group company and subsidiary to the market main body. It is ligament with asset, is no longer the relationship of administrative subordination, through the establishment and improvement of project management responsibility system, the project management effectively to form an overall, coordinated operation, more important.. 2 to establish and improve the engineering department ( a subsidiary company) as the main body of the construction management system.This kind of system requirement engineering department or subsidiaries must be to establish the construction scheme, the configuration of factor of production, heavy and difficult engineering monitor. The project is mainly responsible for the Ministry of construction program implementation, design changes, the daily management and all internal and external relations; company headquarters mainly grasps the organization and coordination, heavy and difficult engineering breakthrough and supervision, to create the external environment, pay attention toGood with the owner, design units and local government relations; company mainly grasps the policy measures, difficult technical advisory services, key and difficult engineering supervision and inspection. Engineering management department especially scheduling, always grasp the situation, unobstructed information feedback channel, solve the problems that cannot be solved.随着我国经济的发展,建筑行业已经朝着多元化方向发展,建筑行业在我国经济发展中起着非常重要的作用。
