Introduction
The development of economy and society has made people’s requirements for material conditions higher and higher. Improving indoor environment and improving the quality of life has become a major topic of concern in today’s society. Correspondingly, in order to meet people’s requirements for the living environment, the development of building decoration and decoration projects is particularly necessary. As a branch of construction engineering, building decoration engineering can not only improve the comfort and aesthetics of the indoor environment, but also have an important impact on the use functions of different commercial buildings. With the expansion of the market demand for decoration and decoration, the difficulty of building decoration construction has been increasing day by day. For decoration and decoration projects, project management and formulate a reasonable management plan, especially the schedule plan, which can timely find construction loopholes and complete the construction with quality and quantity. Therefore, project schedule management has an irreplaceable role, and it is imperative to strengthen the project schedule management of decoration projects.
Construction and classification of building decoration works
(1) Construction of building decoration and decoration projects
The building decoration project is a comprehensive project with artistic appreciation and practicality. According to the “National Economic Industry Classification” (GB/T4754-2011) revised in 2011, the building decoration industry is defined as “the decoration, decoration and cleaning activities in the later stage of the construction project, and the decoration activities for the living room”. In addition, the construction decoration industry, engineering preparation activities, provision of construction equipment services and other unspecified construction industries are collectively included in the construction decoration and other construction industries. It can be seen that the building decoration project has become a branch of the rapid development of the construction industry.
Building decoration engineering has the characteristics of complex process, wide variety of materials, flexible and changeable construction methods, etc., which are determined by the four new requirements of “comfort, beauty, safety and environmental protection” of the living environment. In order to reflect the beauty of decorative arts, a variety of decorative designs are bound to be produced, which makes the construction methods and processes of building decoration and decoration projects also vary. In addition, due to the limited space for decoration and construction, the decoration and decoration project is mainly based on manual labor and supplemented by mechanical equipment. Therefore, a reasonable construction plan must be formulated during the construction of the decoration project. To achieve reasonable decoration construction.
(2) Classification of building decoration and decoration projects
The main construction techniques of building decoration and decoration include: plastering, doors and windows, ceilings, decorative panels, lightweight partition walls, pasting and soft wrapping, finishing, curtain walls and details, etc. The specific content of the building decoration and decoration construction project is shown in Figure 1, including hydropower engineering, paint engineering, waterproofing engineering, surface engineering, carpentry engineering, water supply and drainage engineering and other parts.
Decoration engineering project progress management
(1) The significance of project progress management analysis
One of the most important aspects of project management is project schedule management. The analysis of project schedule management has the following effects:
1.Through progress management, waste of time and cost can be eliminated to the greatest extent, construction efficiency can be improved, and the expected goals can be achieved with high quality and quantity;
2. Reasonable allocation of resources can avoid conflicts between various resources to the greatest extent.
3. Eliminate uncertain factors, optimize and adjust a single progress element or even multiple elements of the project to achieve the relative optimal benefit of the project.
(2) Progress management technology
One of the main features of project engineering is that there are strict time limit requirements, and project schedule management is to control and save time, so schedule management is extremely important in project management.
With the continuous expansion of building decoration and decoration projects, the progress management is becoming more and more complicated, and it needs to be managed through a computer technology system. Network planning technology is an important technical means of project schedule management. It is a scientific method to apply network planning technology to manage project schedule. Its main content includes planning, planning and real-time control, which is not only conducive to shortening the construction period and improving construction efficiency, but also conducive to reducing construction costs and improving enterprise management. Bar chart, critical path method (CPM), critical date table and program review technique (PERT) are commonly used methods in schedule management.
(3) Research content of progress management
Building decoration projects generally have many construction teams, many types of materials and complex construction processes, which require coordination and cooperation between various construction units. Since various types of work are interspersed and the industry is relatively new, many young construction workers have insufficient experience and incomplete theoretical knowledge. Therefore, it is more difficult to manage the progress of the project, which requires a sound management system. The construction part has formulated strong management measures to ensure safe and efficient construction.
In recent years, research on project schedule management has mainly focused on avoiding resource conflicts and reasonably coordinating resource and time and time-cost optimization when multitasking is parallel.
Time-cost optimization is to consider how to minimize the cost when the construction period is the shortest, or how to achieve the shortest construction period when the construction cost is the lowest; it is to comprehensively consider the two factors of the construction period and the construction cost to produce a relatively optimal solution , so as to achieve the optimal combination between the two. Mathematical modeling and heuristic search algorithms have arisen in the search for solutions, but both have certain drawbacks. First of all, the method of mathematical modeling cannot comprehensively consider various factors of the problem, especially those aspects that cannot be quantitatively reflected; in addition, this method is not easy to solve, and sometimes it is found that there is no solution at the end. The heuristic search algorithm relies heavily on empirical methods to get the answer to the question, but it cannot guarantee the optimal solution.
How to coordinate the plan and resources of each project has become the research content of project schedule management, because PERT and CPM are the plan management of a single project without resource constraints, and in reality, many projects exist in an enterprise at the same time, which often occurs The phenomenon that projects interact with each other and compete for resources.
Among project managers, it is very common that the operation time of each operation activity cannot be carried out according to the predetermined requirements due to various emergencies. However, PERT is calculated using an empirical formula, which has a large error compared with the actual operation time. The operation time of CPM is determined. Therefore, how to eliminate the influence of uncertain factors so as to more truly reflect the time of operation activities has also become an important content of the project schedule management discussion.
Improvement of progress management of decoration construction
Strengthening project schedule management requires the perfect combination of effective management methods and means, advanced management ideas and innovative management teams. In addition, strengthening the progress management of building decoration projects is of great significance to ensure construction quality.
(1) Strengthen the training of management personnel
The decoration and decoration industry is an emerging industry in recent years. The construction process of decoration and decoration projects is complex and the quality requirements are high; professional construction personnel and professional management personnel are very lacking. Therefore, in order to improve the quality of decoration and decoration projects, the training of management talents and the business training of existing management personnel should be strengthened. By adding decoration engineering majors in colleges and universities with similar majors, professional talents are cultivated to fill the personnel gap in the industry; at the same time, decoration and decoration enterprises should regularly offer professional training courses to improve the knowledge and literacy of decoration and decoration personnel.
(2) Improvement of project schedule management network technology
Due to the increasing application of computer technology to assist management in project schedule management, project schedule management is developing in the direction of intelligence, integration and networking. There are two network technologies commonly used in project schedule management, one is computer simulation technology and the other is intelligent method. There are many defects in both PERT and CPM in project schedule management. Relatively speaking, PERT considers the project process time factor more comprehensively and reasonably, and has a wider scope of application. Therefore, based on PERT technology, by introducing particle swarm optimization Algorithm PSO, an improved method based on PSO-PERT, namely PSO-PERT technology, is proposed. This method improves the shortcomings of traditional methods and improves the ability to control and adjust the project schedule.
(3) Implement the project manager responsibility system
In order to improve the level of progress management, at the construction site of the building decoration and decoration project, there are corresponding project managers who are responsible for the implementation of the project manager responsibility system. First of all, any person who serves as a project manager must be a person with both relevant qualification certificates and certain management practice experience, so that each construction process can be comprehensively and reasonably managed according to the construction management plan, so as to ensure the decoration project. quality of construction. Secondly, the responsibility system of the project manager should be improved, and the construction responsibility of each link should be put on the manager’s individual, so as to improve the project manager’s sense of responsibility, and a clear reward and punishment system should be established. Personal reward or punishment in order to motivate the individual to work. In addition, we should do a good job in supervision and management, strengthen the supervision of all aspects of construction, and ensure that each construction link can be completed on time with quality and quantity, or appropriately speed up the construction progress to complete the construction ahead of schedule when the construction quality is safe and reliable. Effectively improve the quality of progress management of building decoration projects.
Summarize
To sum up, the industry of building decoration engineering has gradually become popular and developed with the continuous development of social economy. Through the implementation of project progress management in the construction management of architectural decoration and decoration, the purpose of effectively controlling the construction quality can be achieved. At present, the development of decoration and decoration industry in my country is still in the development stage. It is believed that with the advancement of the construction of the modern construction market system and the improvement and improvement of my country’s project management system, the management of building decoration progress will also be more systematic, and the quality of management will be improved. Further Promote the development of building decoration industry.
