In engineering projects, the cost of materials typically accounts for over 60% of the engineering cost. In the engineering project management process, in the engineering cost estimation, approximate calculation, budget, bid control price, bid price, cost budget planning and examination process, accurate material price information is needed to participate in the cost calculation, and the material price is also one of important information and basis of the engineering cost.
The collection and release of the material price information of the construction cost in the engineering project decision process are generally carried out by the information personnel of each provincial and lower level construction cost management departments and the information personnel of the construction cost management units to inquire the price of the material suppliers regularly and report the price information of the local construction material. Each construction unit can also have a price inquiry department to inquire the price and establish a price information base of the enterprise for the cost budget of the enterprise. However, under the price inquiry mechanism, because the material supplier is not specifically associated with the material supply business, the price information has a large floating space, which is not favorable for accurate manufacturing cost, and is also not favorable for material purchasing cost control in later construction, thereby causing poor controllability of the subsequent construction process and increased cost of dynamic investment control management such as material price adjustment.
Under the current technical conditions, there is no better way to solve the above problems for a while. Generally, only in the process of determining the material price, the problem of unreal price is solved by increasing the manpower recheck and the diversification of the collected data, but the problems of difficult personnel coordination, unstable sampled data dispersion and trend and the like are caused by increasing the sampling and recheck, and the accuracy of the project cost material price is not greatly helped.
Through the above analysis, the problems and defects of the prior art are as follows: the existing engineering material price information has the problems of non-authenticity, uncertainty, low transaction efficiency and the like, and the material price information is disjointed from the material purchasing link, so that the engineering cost decision and the engineering implementation cost control are not facilitated.
