No matter in study or work, everyone will inevitably come into contact with papers, which are articles for us to study a certain problem in depth. So, have you understood this paper? The following is my paper on the current situation and strengthening measures of housing construction project management and cost management. Welcome to read the collection.

abstract:

In the process of urbanization, housing construction projects have developed rapidly, and housing construction units have mushroomed, dividing up the current construction market. In the intensified housing construction project, the construction unit can only control the housing construction cost and ensure the construction quality by doing a good job in project management and cost management. This paper mainly starts with the current situation of project management and cost management of housing construction projects, analyzes their shortcomings, and then adopts corresponding strategies to ensure that urban housing construction projects can not only achieve high-speed and high-quality development, but also cater to the planning objectives of ecological and civilized cities.

Housing construction projects; Cost management; Project management; Strategy;

Residential construction project management is an important part of construction project management. In management, we should be able to make overall plans. It is also required to compile the on-site construction scheme according to the house building design scheme to realize the optimal control of the whole process cost of the house building project. But in fact, most of the current project management and cost management of housing construction projects have unscientific management concepts, which makes it impossible to carry out the whole process of project management and cost management; Secondly, because the professionals of building construction engineering are not professional, it is urgent to explore the problems existing in current management and find effective solutions.

1, current situation of project management and cost management of housing construction projects

According to the practical experience of housing construction projects, the economic and social benefits of project management and cost management of current housing construction projects are not ideal.

(1) There are obvious deficiencies in project management and cost management of housing construction. In China's urbanization planning and construction, more and more housing construction projects have emerged, and the scale and standards of housing construction in different regions are not the same, which leads to the randomness of project management and cost management in actual construction site management. For example, some small housing construction projects have small quantities and short construction period, and there is no need to manage the whole process of the project at all. But often in this kind of projects, it is easier to waste housing construction resources and increase housing construction costs, which is not conducive to the development of low-carbon economy.

(2) The lack of supervision mechanism in project management and cost management of housing construction projects leads to the arbitrariness of their management activities. For housing construction projects, it is necessary to introduce professional teams and institutions to supervise and manage the quality of construction progress and optimize the control of construction costs. However, in fact, the current housing construction project has not been able to introduce supervisors to supervise the whole process of project cost management. For example, a building construction project, although it has formed a cooperative relationship with the supervision unit, has carried out quality audit and supervision on the construction site in the construction project. However, these supervisors failed to participate in the quality supervision and management of design drawings and construction documents. Generally speaking, the current project management and cost management of housing construction projects have one-sided characteristics.

2. Optimization measures for project management and cost management of housing construction projects.

2. 1 housing construction project management strategy

(1) schedule management strategy of housing construction project:

(1) It is required to coordinate the whole construction project and realize the overall planning of the project. In the process of construction, all internal and external factors such as human resources, market factors and weather factors are comprehensively considered, and the construction project plan is formulated based on architectural design planning, and the progress of each construction link is clarified.

(2) Site construction management requirements. According to the construction progress of different subdivisional work, arrange daily work scientifically and reasonably. For example, in housing construction, the mobility of civil construction workers is high, and the progress of work that can be completed every day is different. Therefore, it is required to strengthen the on-site management of the whole building construction project, so that the on-site construction plan is accurate, so as to realize the reasonable deployment of each construction link. At the same time, in the control of the project progress, it is necessary to optimize the deployment and use of various mechanical equipment to avoid that sometimes all mechanical equipment stops working, and sometimes the lack of mechanical equipment affects the project progress.

(2) Quality management strategy of residential construction projects. The quality and safety of building engineering is an important issue in the management of the whole building engineering.

(1) It is required to continuously improve the construction standards of housing construction projects. For example, in housing construction, a scientific and reasonable quality inspection standard system is formulated according to national standards and on-site construction conditions, and the development principle of "safety first, quality first" is strictly required at the construction site;

(2) It is required to continuously train the professional skills of the construction personnel, improve the overall quality of the construction personnel, make them abide by the construction technical standards in daily construction, and carry out scientific on-site construction. For example, in concrete mixing construction, mixing time, mixing sequence and cement specifications used will affect the final quality of the whole concrete and the quality and safety of the whole building project. If we can improve the professional quality and construction technology of construction personnel, we can do a good job in construction quality control in site construction;

(3) Quality control of construction elements is required. In building engineering, the quality of building materials directly affects the quality and safety of building engineering. Therefore, it is required to strictly control building materials, do a good job of quality sampling inspection when building materials enter the factory, prevent products with incomplete licenses from entering the construction site, and sample materials for inspection, so as to obtain a true and reliable quality inspection report. Fourth, do a good job in technical management of the construction site. On-site supervisors should have professional construction technology, which can effectively guide technical problems in construction. Provide corresponding safety protection measures for some possible safety problems, fully mobilize the enthusiasm and sense of responsibility of construction personnel, so as to ensure the quality and efficiency in the construction process.

2.2 residential construction project cost management strategy

The optimization of the cost management strategy of housing construction projects requires that the whole process of cost management can be realized, and the effect of cost control management and the economic and social benefits of housing construction units can be avoided because only the project cost control in the construction stage is carried out.

(1) Cost management in the decision-making stage of housing construction projects. The investment decision and investment scheme of residential construction projects have great influence on the project cost. For example, the impact on architectural design level and building standards. Therefore, in the decision-making process of housing construction projects:

(1) Determine the construction scale and standards. In real estate construction projects, the choice of construction scale directly affects the project cost. For example, some construction projects have high costs, and they realize the maximum utilization of resources, which is not restricted by external resources such as market, technology and environment. The determination of building standards is the basis of building scheme selection. The investment situation of construction projects determines whether the construction projects are economical, applicable or advanced and comfortable, and the building structure and building materials used have also changed. Therefore, it is required to do a good job in cost control management at the decision-making stage and make clear the construction plan;

(2) Determination of materials and equipment. Materials and equipment are two of the five factors that affect the quality and cost of housing construction projects. In the project decision-making stage, it is necessary to make a budget for materials and equipment, and make clear whether the materials used are imported or local, and whether all construction materials are compatible.

(2) Cost management in the design stage of housing construction project:

(1) At the beginning of the housing design scheme, the engineering design will be exchanged and discussed according to the design principles and standards of the bidding design contract. Ensure that the bill of quantities can be designed in the construction design drawing, and provide quantities and technical specifications for the project cost budget;

(2) Strictly examine and approve the contents and costs of design changes, and minimize the costs of design changes, unless it is absolutely necessary not to carry out design changes.

(3) cost management in the construction stage of housing construction project:

(1) Optimize the construction scheme. In the field construction, we should be able to choose the construction scheme of each construction link to ensure the effect of cost management;

(2) Optimize the construction progress. By strengthening the construction organization, reasonably arranging the operators according to the working conditions on the construction site, and doing well the coordination and handover of each working procedure. Ensure the construction progress, so as to control the cost of the construction stage.

3. Conclusion

To sum up, as an important pillar of the national economy, the quality and safety of construction projects are of great significance to urban progress and social stability. Under the modern management concept, project management concept has become the main guiding concept of housing construction management. By establishing management organization, clarifying the content of construction responsibility and carrying out construction quality management, the cost optimization control of the whole housing construction project can be realized. Only in this way can we fundamentally manage the whole process of quality and safety of housing construction projects.
