Investment control of engineering construction projects is one of the important tasks of economic construction and plays a decisive role in national economic construction and development. In the past 20 years of reform and opening up, while China's economic construction has made brilliant achievements, the investment control of engineering projects has also made remarkable achievements. Practice has proved that in order to control the investment of construction projects well, it is necessary not only to have professionals with high professional quality to control the investment of construction projects, but also to control the whole process in an all-round and focused way. Combined with years of investment control work, the author talks about his own thinking from four key aspects: optimal design of investment control, doing well in bidding, scientific management and strengthening audit, hoping to play a role in attracting jade. 1. Optimal design According to the data, in the decision-making and design stage of the project, the possibility of affecting the project investment is 30-75%, while in the construction stage, the possibility of affecting the project investment is only 5-25%. Obviously, the decision-making and design stage of the project is the key stage of project investment control. After project decision-making, the key to controlling investment lies in scientific design. Once the design drawings are completed. The structural form, decoration standards, materials and equipment selection of the project are determined. The investment amount of the project has also been basically determined. For a long time, designers of design units in China have paid more attention to design quality, progress and engineering technology, but paid little attention to project cost. Some engineering designers have a weak economic concept and usually think that the technology is feasible and the quality is reliable. Even if the task is completed, the project cost is a matter for the budget staff, not for themselves. Due to economic considerations, the concentration of construction drawings is not enough, which is "collision, lack, leakage" and "fat". In the long run, it will inevitably lead to a great waste of national construction bonuses. Therefore, it is necessary to strengthen the optimization design. In the design stage, not only from the technical point of view, but more importantly, from the perspective of the combination of technology and economy, scientific theoretical methods should be adopted to strengthen economic argumentation and optimize the design scheme. Cost-benefit analysis method can be used for comparison and selection of schemes. On the premise of satisfying the engineering structure and use function, the design scheme is selected according to the economic index. Once the design scheme is determined. You can also use the method of value engineering to reduce the project cost as much as possible. Value engineering is a set of scientific and modern means to improve the value of products by analyzing the functions of products and making them reliably realize the necessary functions of products at the lowest total cost. By using this method, functions can be refined, redundant functions can be removed, and key controls can be implemented for functions with high cost, so as to finally reduce project investment and realize the best economic, social and environmental benefits of construction projects. Second, bidding is an important means to control investment. From the aspects of design, construction, equipment, supply, supervision, etc., we will carry out all-round and whole-process bidding and selection, effectively put an end to unfair competition in the process of project bidding and further standardize the construction market. Bidding is a complex competitive trade mode and a serious legal act, which requires the bidding business personnel to be particularly proficient in bidding procedures and skills, as well as to understand the knowledge of law, finance, economy, foreign trade and so on. , so it must be carried out by specialized personnel, otherwise legal disputes will easily occur. Pay attention to the following aspects when bidding: 1. The rationality of pre-tender estimate reflects the price of building products. Mainly according to the current national quota, cost, equipment, material prices, design quantities and other provisions. According to the law of value theory, when the commodity price exceeds the demand (construction capacity), it should be said that it embodies the principle of fair competition and conforms to the basic rules of market economy. However, in our actual bidding project, the pre-tender estimate deviates too much from the value of building products. The main reasons are tight pre-tender time, rough working group or low quality of personnel, and inaccurate calculation of engineering quantity. Unreasonable quota and material price selection. Therefore, the preparation of the pre-tender estimate must be given enough time and must be prepared by a unit with corresponding qualifications. 2. Standardizing the tender offer is the independent pricing of the project by the construction enterprise, which embodies the independent pricing right of the enterprise. The independent pricing of enterprises must be based on the calculation of their own costs, reflecting the organic combination of "personal labor time" and "social labor time" of enterprises, and the bidding quotation should be based on this. At the same time, the basic guiding principle of "unified engineering quantity, guided price and competitive charge" should be embodied in the project bidding, and the direct cost of the project should not be arbitrarily lowered, which deviates from the fixed pricing basis. Otherwise, once the bid is won, not only the contractor will suffer losses, but also the owner will suffer greater losses. 3. Fairness of bid evaluation rules Bid evaluation and calibration are the most critical links in bidding work. To reflect the fairness and rationality of bidding, there must be a fair, reasonable, scientific, advanced and operable bid evaluation method. Due to the disorderly competition in the construction market in some areas, the obvious irregularities and unfairness in the bidding process should be put an end to. Three. Scientific Management With the establishment of the socialist market economy, the scientific management of construction projects has been greatly improved. Years of practice have proved that management benefits and investment savings have been recognized by more and more owners and contractors, making both owners and contractors consciously put scientific management in the first place in the construction process. Scientific management of construction projects runs through the whole process from preparation to completion and acceptance, including all-round management of people, money and materials. However, influenced by profit-driven and money worship, there are two kinds of bad tendencies in construction projects. First, some contractors blindly pursue high profits and cut corners, resulting in inferior or scrapped products and various quality accidents; The other is poor management and unscientific construction organization in the construction process, resulting in slowdown, rework and waste of people, money and materials. The unconstructive cost is too large, which leads to serious out-of-control investment. It is believed that with the continuous improvement of understanding between owners and contractors, the scientific management of construction projects will surely become one of the indispensable and important means of investment control. Fourth, strengthening price evaluation and strengthening the examination and audit of construction projects are important measures to control investment. From the beginning of the project, it is necessary to strengthen the review and audit, dynamically track the whole process of funds and use, and control the three links of the project in the early, middle and late stages. This is an effective way to solve the "three super" ills. There are many reasons for its construction project "three super". If the initial design of the project does not reach the specified depth and the work is rough, it will lead to the increase of engineering quantity or the expansion of investment regulations or other uses during the project implementation. When budgeting, budget personnel mechanically apply indicators or make improper adjustments; When budgeting, the quota and project selection are unreasonable; The price positioning of equipment and materials is inaccurate, which has the influence of "the consciousness of the chief executive and the thought of the owner". These are all important factors that cause investment distortion. Therefore, in the early stage of the project, the design scheme, equipment selection, investment estimation, budgetary estimate and investment benefit should be reviewed. In the middle of the project, that is, the project implementation stage, the equipment, material orders, project budget and project progress payment should be tracked and audited. In the later stage of the project, the key point is to review the settlement and final accounts of the project. More specifically, the review of project budget and settlement is an important stage to control investment and improve investment efficiency. At the same time, the remaining amount of the project can only be confirmed after review. Since the opening of the construction market, disputes between the construction unit and the construction unit on the method of project budget (settlement) have occurred from time to time, and sometimes the contradiction is very sharp, which requires entrusting the engineering cost intermediary agency to conduct a reasonable price evaluation. The entrusted intermediary institution must hold the project cost certificate, and it cannot be entrusted without the certificate. According to my years of practice, some projects and procedures submitted for review are overestimated and calculated to varying degrees, and some even reach more than 30%, which is surprising. Only through the fair evaluation of the price by the intermediary agency can the dispute be effectively resolved. In short, investors should review the accuracy of budget estimates, the authenticity of project budgets and the rationality of expenditures. From the above analysis, it can be considered that optimizing design, doing well in bidding and scientific management, such as strong price evaluation, will greatly promote investment control. It should be said that its specific operation is feasible and its potential benefits are obvious. The key is whether we can practice boldly and explore creatively. If the investment control of the project can be done well, it will add a beautiful scenery to improve the construction market mechanism.
