Project cost is the main content of construction project, because the efficiency of cost control directly affects the economic benefits of construction project. It is the ultimate task of modern project management for engineering units to do a good job in cost control and strictly control the cost input of each link. In order to ensure that the cost of the whole construction project is controlled within a reasonable range, it is necessary to constantly improve the technical management and economic management of the whole production process of the project. In view of this, this paper focuses on the analysis of related issues of construction project cost control.

Keywords: construction cost control management

The reform of market economy system has made the construction industry a hot spot for investment, which has promoted the construction cost. Project cost management directly affects the economic benefits of construction investment and promotes the development of the whole market economy and the individual operation of the unit. From the actual situation, the quality of construction cost management in China is low, the project cost capital investment is high, and the project cost management system faces many problems, which hinders the sustainable development of the construction industry.

First, the significance of reducing the cost of construction projects

The project cost involves many aspects, such as construction and installation costs, equipment purchase costs, other costs and so on. Construction project cost management is the focus of daily management of engineering units, which directly affects the economic value created by construction projects. From the point of view of engineering units, only by implementing technical management and economic management in the whole production process of engineering projects can the expected construction effect be achieved.

The efficiency of construction project cost management has a great influence on the whole project investment, which not only affects the economic investment benefit, but also affects the survival and development of engineering units. Due to the large scale, long construction period, high technical difficulty and high resource consumption of construction projects, it is necessary to ensure the accuracy of investment in order to fully display the value of economic benefits. If the cost policy of the engineering unit is wrong, it will lead to many economic losses. Therefore, in order to realize the reasonable control of the project cost, it is necessary to carry out multiple pricing in each construction stage and control the cost with reference to the reasonable operation process.

Second, the principle of construction project cost management should be adhered to

1, coordinate the relationship and control the quality. Here? Relationship? Refers to the relationship between project cost and construction quality. Project cost is mainly the comprehensive cost of labor, machinery and materials needed to end a project. According to the nature of investors, designers, builders, contractors, auditors and other units, the required expenses are different. Such as: investment estimation, design budget, construction drawing budget, contract price, settlement price, completion settlement, etc. The quality of the project is mainly that after the completion of the project, the performance of the building should meet the drawing standards, and all technical parameters should meet the drawing standards. Considering the relationship between project cost and project quality, and the life cycle of the project changes with the change of project cost and project quality, we control the project cost more strictly. It should be noted that the investment in construction projects should not only focus on reducing costs and saving funds, but also be fully spent on the necessary cost input of the project, so as to avoid the shortage of engineering expenses caused by cost saving and make the construction operation difficult to proceed smoothly.

2. Renew ideas and optimize management. Value engineering can be regarded as value analysis, which is of great significance to improve the internal quality of buildings. It is the pursuit of every engineering unit to analyze and evaluate the functions of construction projects from various aspects and reduce the project cost. In the process of architectural design, every construction unit should combine the functional requirements of the project with the investment, and reduce the cost input through effective measures according to the specific requirements of the project construction.

Third, the cost control and management measures at all stages of the construction project

1, cost control and management in decision-making stage. The biggest task in the investment decision-making stage is to conduct a comprehensive feasibility analysis of the project to determine whether the selected scheme can be put into practical work. When the project is in this period, the tasks that project cost management must complete include determining the scheme, making the plan and estimating the investment. Investment estimation plays an important role in the whole project, which is the main basis for project decision-making, design, construction and final accounts, and plays a decisive role in the total investment of construction projects. In the decision-making stage, both sides of the unit should consider from their own point of view, formulate a plan that meets the needs in the complex correlation and factors, and then make a reasonable valuation according to the plan. The accuracy of investment estimation will affect the effectiveness of project implementation. This requires engineering units to base themselves on reality and arrange high-level professional units for investment estimation.

2. Cost control and management in the design stage. Design work is the soul of engineering construction, which has guiding significance for dealing with the relationship between technology and economy, especially for the control of engineering cost. The optimization of the engineering scheme directly affects the one-time investment of the construction project, and will have an impact on the economic benefits created after the project is completed and put into use. The construction unit must do a good job in optimizing the design scheme when reviewing the scheme formulated by the design unit. From the perspective of long-term project construction, the cost can be reduced by optimizing and improving the scheme before the project implementation, which reminds the engineering unit that in order to fundamentally reduce the project cost, it is necessary to focus on the optimization of the previous scheme. Adopting different scheme optimization measures can simplify the construction process, avoid the waste of materials, equipment and resources, and save money in many ways.

3. Cost control and management in the bidding stage. When compiling the tender documents, the engineering unit must consider from multiple angles, so as to facilitate the construction agent and the bidder to control the project cost. The design content needs to be relaxed, and the use of various funds must be appraised by professional auditors. For engineering contractors, in addition to considering their construction technology, they also need to focus on the given contract price. In addition, we need to make relevant provisions on the adjustment of quotation in the bill of quantities. When there are errors in the bill of quantities and engineering changes lead to errors between the quantities and the contract provisions, we need appropriate additional funds to change the fees and taxes in time. This is to ensure the stability of the project cost, so as not to change too much and affect the cost management. It is particularly important for the construction unit to sign a contract, and the key contents need to be clearly stipulated in the contract. Combined with the actual situation of the construction market, strictly control the cost of materials used in project construction to avoid the problem of high cost caused by various factors.

Four. conclusion

In a word, the cost management of construction projects is an indispensable part of construction projects. In the process of construction, it is necessary to make various preparations, control the whole cost investment within an effective range, and achieve greater economic benefits for the project. The construction unit should actively combine the principles of science and technology with economic and legal means to handle the engineering tasks well. For building construction in different periods, we should fully adopt effective cost control strategies, formulate cost management plans according to the changing trend of market economy, and finally maximize economic benefits.
