A, the project cost out of control factors

1. Unfair bidding

Bidding is an important reform measure in project construction, which is conducive to controlling project investment, breaking the division and monopoly of industries and regions, protecting competition, eliminating inertia and invigorating highway construction industry, thus effectively controlling project cost. Bidding is to attract some excellent teams with practical experience, good reputation, remarkable performance and qualifications that meet the requirements of the project through competition, and to have practical plans, good management level and construction organization for the project cost. However, at present, there is unreasonable competition in the bidding process, and some authoritative people trade construction projects by improper means, and the project is designated as a related household and human project, so the project cost is difficult to control. For the benefit of their own enterprises, the construction unit blindly asks for additional project cost, so this kind of bidding does not conform to the project, and the designated contractor brings great losses to the country, which is also a hidden danger of high project cost.

2. There are many problems in the unit.

The project cost is uncontrollable and difficult to manage, and there are powerful people behind it. Some people with good relationships have less work and more accounts, which makes the project management very difficult, which invisibly increases the project cost. Increase the unit price of engineering materials, because Cui is an economic market and more competitive. For some people with poor quality and real engineering strength, this is a good opportunity to shine and make a fortune. They have mastered the golden key to this project. It is up to them whether they can give you the project and let you bid, so they make a big fuss about engineering materials, monopolize the material market and make highway gravel indispensable. It is the basic material for highway and stone processing. All the materials for the project are supplied by them, and the unit price of materials is higher than that in other markets, but others can't say the quality. It brings great disadvantages to the project quality, and the project cost keeps rising, which is out of control.

3. The engineering survey is inconsistent with the actual situation

Engineering measurement means that after the project quantity is completed, the quality has been recognized by the supervisor, and the project quantity conforms to the construction practice, and it is measured by the supervisor visa and submitted to the project department for approval. Often in engineering, the project department of the project carries out project management on behalf of the construction unit. However, a few people in the project department violated the management principles of the department and forgot that they were the representatives of the owners. Instead, he put himself among unprincipled supervisors and lost his responsibility. They play an uncoordinated role in the measurement work. If the construction unit can't measure, as the owner's representative, they will pay for the supervision work as the construction unit. What is even more difficult to understand is that a few people in the project department have measured the construction unit without the consent of the supervision department. In a construction project in expressway, they overcharged the construction unit by 6,543,800 yuan, which infringed on the national interests, caused losses to the national economy and seriously exceeded the project cost. The project cost is out of control, which makes a project construction activity lose its true reflection and record.

4. Chief Executive's will: A few construction units try their best to ask the state for more money for the benefit of the region and change the documents of design units at will. Increase the amount of compensation and land acquisition, and this project alone will double. Increase the unit price of materials and change the construction method, for example, "one kilogram of ordinary paint is close to 50 yuan. Because there are two design units in a section of road, the entrusting unit is required to budget according to the information provided by them, regardless of how to control the project cost, and blindly seek the interests of their small area, which improves the project cost. During the construction, the original design is modified at will, the expansion project is added, and the design standard is improved, which makes the project cost higher and higher.

5. There are many management organizations: the determination of the project cost has a direct interest relationship with the design, construction unit, construction unit and bank, so each unit has different reactions to the level of the project cost, and it is difficult to control the project cost.

Second, how to effectively control the project cost

1. Fair competition and reasonable bidding

The purpose of fair and reasonable bidding is to make the project cost more reasonable after competition, arrange the project plan reasonably and control the project cost effectively. The project cost of the construction project through bidding is more reasonable, and it can also be said that bidding is also a new economic contract system within the scope of capital construction. Therefore, in the process of bidding, it is necessary to have clear transparency, so that the tendering units can know about the bidding work, limit some unfavorable bidding factors, truly embody fair competition in the economic market, and invite construction units with real technical strength, strong technical strength and quality awareness, good quality and considerable engineering construction experience to bid. There is a good foundation for highway construction bidding, and the tendering unit is convinced. After the project bidding, the winning bidder signs the construction contract before the construction, so the project cost is determined.

2. Determination of current labor price.

A. China's general experience and method of dividing wage zones: according to the economic development of provinces, municipalities and autonomous regions, the price index of daily necessities and general price index, and the demand of labor force, the "labor price" guiding index is issued regularly according to the contents of document No.894 issued by the Ministry of Construction and the People's Bank of China (1993).

B, the national "labor price" index maximum.

C, according to the adjustment of provinces, municipalities and autonomous regions

To sum up, the cost management of construction projects at this stage is in the transitional stage of reform, and various restructuring and management systems have not yet been synchronized. For the establishment of "artificial price", it is not enough to unify it, nor is it enough to push it to the market. Therefore, it is normal to adopt an "active and steady" transition mode. Labor price is an important basis for calculating labor cost, which is an important part of the price of building products, so the method of "scientific and reasonable" should be adopted in the formulation of labor price. At the same time, the labor price is closely related to the economic base of each province and city. The artificial price can't be too far from the economic base. For example, Shaanxi's economy ranks more than a dozen in the country, while labor prices rank in the top few. How to deal with this problem was discussed at the cost meeting of the Provincial Communications Department, and the Communications Department is further properly solving and improving it.

D. Effectively restrict officials from participating in the project.

Highway construction projects are the basic construction of the country, and engineering materials will be the foundation of highway construction. No one can monopolize and dominate the material market, and officials cannot participate. People's government departments in the process of project implementation is macro management, not dedication and money. If the government wants to take corresponding measures against the officials and the people, it must expressly stipulate that the officials and the people are not allowed to do business, which has long been stipulated by the central government. Whenever officials or children participate in the project, first, the project cost is high; Secondly, the quality of the project is poor; Thirdly, the public response is great, which makes the government departments lose the essence of macro management of the project. Although this is a small number of people, the consequences are great, and it is also the focus problem that the project cost is difficult to control effectively, which brings unfavorable factors to highway construction and seriously affects the normal development of highway construction.

E, improve the cost management measures, and strive to accurately carry out cost management and project cost management, which is also a new thing and urgent task in economic construction. In the implementation of project cost management, new methods and policies are still being further explored. It is necessary to repair and improve the defects existing in the current cost management. It is also in the implementation that a set of scientific cost management methods and corresponding policies are summarized to push the highway engineering cost to an advanced level suitable for the national conditions. In highway construction, government departments should have their own series of documents and regulations, and formulate some documents and instructions that are beneficial to highway construction, actively promote the normal development of highway undertakings, continuously improve the technical level and construction technology of the project, save state funds, spend money on the cutting edge, and make the project cost reasonably controlled.
