As one of the pillar industries of China's economy, the construction level of the construction industry has been steadily improving. Housing construction projects involve the installation, decoration and construction of various housing buildings and related supporting facilities, and their quality is closely related to the safety of housing and the comfort of residents' lives. With the increasing requirements of the public for the construction quality of housing construction projects, the construction management and quality control of related projects are also facing huge challenges, and relevant professionals and units must conduct in-depth research on this.
Problems existing in the management and construction of housing construction projects.
1. It is difficult to coordinate construction cost, construction period and quality.
In the construction of housing construction projects, there is an inextricable link between construction costs, construction period and quality, and a longer construction period means that more labor costs and equipment costs will be invested, and if the specified construction period is exceeded, there will be a risk of default. However, if we catch up with the construction deadline in order to save costs, we may not be able to ensure the quality of the project. In addition, in order to ensure the quality of the project, it is necessary to use better quality engineering materials and more advanced construction equipment, which means that the cost will be increased accordingly. Therefore, it can be seen that the coordination of construction cost, construction period and quality is the key to the construction management of housing construction projects. However, now some construction units do not have this kind of scientific awareness, in the process of construction management due to the blind pursuit of interests and the occurrence of rushing, greatly shortening the construction period, cutting corners and other phenomena, these are not conducive to the guarantee of project quality, has become the contemporary society hated behavior.
2. The construction management mechanism is not scientific.
At this stage, the management team of many housing construction projects in China is facing the dilemma of the integration of old and new technologies and the conflict between old and new management concepts, especially the lack of supporting management mechanisms for some new housing construction technologies, and the traditional management mode can not give full play to the advantages of these new technologies and construction methods. The reason for this is that the housing construction management team lacks a sense of innovation and is unwilling to invest more energy and cost in the innovation of construction technology and management mechanism. For example, during the construction of many housing projects, a large number of manpower or equipment with relatively high energy consumption are still relied upon, resulting in construction efficiency, quality and economy are not guaranteed, and do not meet the current social requirements for the engineering construction industry.
3. Weak supervision of construction management.
The management objects of the construction site of housing construction projects include material access and access, equipment use and maintenance, construction personnel behavior, construction process quality, cost control, etc., and more construction management objects mean that the construction supervision work is facing great challenges, and it is necessary to improve the effective supervision mechanism to ensure that each link and details meet the requirements. However, in most housing construction projects, the construction unit and the contractor are independent of each other, resulting in a lack of professional and experienced personnel on the construction site to carry out on-site supervision to strict standards. In particular, many supervisors carry out supervision work only as a formality, without in-depth evaluation of material consumption, process quality and on-site safety management.
4 The professional quality of practitioners is uneven.
In the current industrial environment, a considerable number of personnel in the construction team of housing construction projects have not received professional training, and the construction technology mastered is relatively traditional, and they do not know enough about the current advanced housing engineering construction technology. In addition, the awareness of this part of the personnel in construction safety, quality and other aspects is insufficient, and there is a phenomenon of lazy and random behavior in the construction process. In addition to the front-line construction personnel, the construction management personnel of many housing projects do not have sufficient professional level, which is mainly manifested in the unfamiliarity with the new construction management concept and the lack of on-site management experience. These factors have led to unsatisfactory project management effect and construction quality.
5. Inadequate security management.
In the process of housing construction engineering, there are many types of materials involved, the process is complex, and the number of construction personnel is large, especially now that the scale of construction projects is getting larger and larger, which brings great challenges to the safety management of the construction site. It is mainly manifested in the fact that the construction personnel do not receive systematic safety training before taking up their posts, and there are many potential safety hazards in the management of on-site construction materials and equipment. Inadequate safety management will not only threaten the safety of personnel and property on the construction site, but also affect the progress and quality of construction.
Analyze strategies to improve the management and construction quality of housing construction projects.
1. Establish a sound construction site management system.
First of all, the construction of any housing construction project must develop a set of reasonable management standards, now the domestic construction quality management standard is ISO9000 standard, with this standard as the core of the construction site quality assurance system, in the management of the construction site has a good guiding significance. Before the construction of a construction project starts, it is necessary to build a set of management mechanisms including personnel, materials, equipment, quality and other indicators. The supervision team composed of the person in charge of the contractor, the person in charge of the construction, the supervisor and the cost control personnel will work together to manage different areas of the construction site. In addition, the main task of the construction management mechanism and management team also includes the coordination of all aspects of work, on the premise of ensuring the quality and duration of the project, improving the utilization rate of human and technical resources, reducing material waste, reducing construction costs, and improving construction efficiency.
2. Establish a rigorous training mechanism for practitioners.
Although the construction of contemporary housing construction has gradually realized mechanization, the management of construction personnel is still one of the important tasks of project site management. On the one hand, it is necessary to establish a rigorous access mechanism for construction personnel and management personnel, requiring each person to have the professional ability that their respective positions should haveOn the other hand, through a rigorous personnel training mechanism, the professional level and professionalism of construction personnel are continuously improved, and each personnel is required to have a sense of responsibility, safety awareness and quality awareness. From a management point of view, managers are required to be familiar with the construction site and project quality standards, know how to coordinate the work of on-site materials, equipment and personnel, maintain order on the construction site, and ensure the construction period, quality and safety.
3. Optimize the material and equipment management mechanism.
In terms of materials, the construction site management personnel shall check the materials on site one by one in accordance with the list of engineering materials to ensure that the relevant materials meet the quality standards. At the same time, coordinate with the material supplier and the warehouse, reasonably coordinate the amount of materials entering the site according to the construction plan and arrangement, and plan the stacking location of materials at the construction site, and do a good job of material protection in combination with the on-site environment. At the construction site, it is necessary to build a material entry and exit mechanism, reasonably control the amount of materials used in accordance with each construction link and the construction plan of the construction team, and make records.
In terms of equipment, equipment operators are required to hold certificates to work, reasonably coordinate the relationship between equipment operation and personnel construction, and avoid interfering with equipment construction or causing safety threats to construction personnel. Establish a rigorous equipment maintenance mechanism, require personnel with relevant professional and technical knowledge to check the equipment status before and after the use of the equipment, and eliminate hidden faults in time to maintain the equipment status.
4. Strengthen the construction site inspection mechanism.
The construction site management team, under the strict inspection mechanism, carries out inspections for all aspects of the construction site.
The inspection content mainly includes the following aspects:
Construction quality. The inspection team must carry out inspections on the construction process of each link of the construction site, find out in time that the construction method is not standardized, the quality is not up to standard, and after the completion of each link of construction, do a good job of acceptance assessment with the person in charge of this part.
Construction safety. Investigate the potential safety hazards on the site, such as the operation standardization of the equipment, whether the personnel wear safety equipment, etc., and check the personnel action route and enclosure system of the entire site to check the loopholes.
Material waste. The inspection team should also supervise the use of on-site materials, supervise the waste of materials, improve the utilization rate of construction materials, and strictly eliminate any waste and destruction of engineering resources. Regularly assess material consumption, analyze the causes of exceedances, implement responsibilities, and develop follow-up optimization plans.
5. Introduce information electronic management system.
With the continuous development of information technology, the on-site management and quality supervision of housing construction projects can also be carried out with the help of modern technical systems. For example, with the help of the personnel management system and the on-site access control system, the entry and exit of construction personnel are managed, and the behavior of construction personnel is constrained through the score system, and violations of rules and disciplines and unsafe behaviors are supervisedConfigure a high-definition camera monitoring system on site to monitor the construction site in real time and improve the management efficiency of on-site management personnelThrough the construction site material and equipment management system, the material consumption and equipment function status are evaluated, and the subsequent construction is optimized. In addition, relying on the engineering digital system, with the engineering design drawings as the standard, strengthen the quality assessment and inspection of each link of the project, find quality problems in time, optimize the follow-up construction method while scientifically processing, and comprehensively improve the construction quality of the project.
In general, housing construction projects involve important places for people's life and production, and their quality is closely related to the public's living comfort and life and property safety. In view of the many problems existing in the construction of traditional housing construction projects, engineering contractors and construction units need to actively optimize the on-site management mechanism with joint supervision and cost personnel, establish a rigorous management system, and implement responsibilities. On this basis, through a rigorous on-site inspection system, we ensure that the construction site personnel maintain a code of conduct, and the use of materials and equipment is reasonable and safe, and finally ensure the rationality of the cost under the premise of ensuring the construction period and construction quality. This is the embodiment of the management level of contemporary engineering sites, and it is also the key to improving the level of engineering construction.
