【正文】 ls stolen have occurred from time to time。 control labor costs, material costs, Machinery and other indirect costs. With the construction market petition intensifies, more and the price low, the scene increasingly high management fees. This requires project managers to more scientific and more rigorous management approach to the management of the project. As a management departments should be a reasonable analysis of regional economic disparities, to prevent the input across the board. From the foregoing analysis, project manageme nt and cost control are plementary, it is only by strengthening project management, can control project costs。 Ministry of Economic Affairs should strengthen budget management contract, the project to create the budget revenue。INTRODUCTION project a corporate image window and effectiveness of the source. With increasingly fierce market petition, the quality of work and the construction of civilizations rising material prices fluctuations. uncertainties and other factors, make the project operational in a relatively tough environment. So the cost of control is through the building of the project since the bidding phase of acceptance until the pletion of the entire process, It is a prehensive enterprise cost management an important part, we must anize and control measures in height to the attention with a view to improving the economic efficiency of enterprises to achieve the purpose. 2, outlining the construction project cost control, the cost of the project refers to the cost and process of formation occurred, on the production and operation of the amount of human resources, material resources and expenses, guidance, supervision, regulation and restrictions, in a timely manner to prevent, detect and correct errors in order to control costs in all project costs within the intended target. to guarantee the production and operation of enterprises benefits. 3, the cost of the construction enterprise principles of construction enterprises control the cost of control is based on cost control of construction project for the center, Construction of the project cost control principle is the enterprise cost management infrastructure and the core, Construction Project Manager in the Ministry of Construction of the project cost control process, we must adhere to the following basic principles. Principles lowest cost. Construction of the project cost control, the basic purpose is to cost management through various means, promote construction projects continue to reduce costs, to achieve the lowest possible cost of the objective requirements. The implementation of the principle of minimum cost, attention should be given to the possibility of reducing costs and reasonable cost of the minimum. While various mining capacity to reduce costs so that possibility into reality。 engineering technology department should ensure the quality, Regular tasks to plete as much as possible under the premise adopt advanced technology in order to reduce costs。 paid attention to quality control to eliminate redone, shorten the acceptance and reduce expenses。 informative。 but also by contracting, design, Enterprises and other projects related to the construction of the units affected and constrained. In addition, geological and climate changes, Design changes, but on objective factors of the construction projects have a significant impact, and all of the above factors will affect the cost of project expenditures. 1. subjective reasons lost control of the cost of the socalled subjective reasons, refer to the project, can not dispose of any external influence on the control of the costs, As mentioned above the project with the Ministry of Construction for the autonomy of the cost. mainly include the following aspects : ⑴ no strict cost control of the overall goal or no cost control goals. Most of the loss items Department head, there is no cost control goals. Although some but not strictly enforced, thus the cost of the project is out of control. ⑵ materials, spare parts planning, procurement, inspection, custody, out of the reservoir, consumption of the system is not sound. the loss of the item, the purchase of materials and accessories unplanned phenomenon abound. procurement lies in the number of project managers even material, the result is bound to lead to a backlog of material, cost overruns. As the project is difficult to grasp the Department of the relatively reasonable price information for the procurement of materials not calculated the cost of capital. so that the item purchased a large quantity of highvalue materials. some items of no transceiver system, the purchase of materials unmanned testing, No more physical account, which can not be kept out and the. particularly aggregate, tile, etc. to build. Some project the Ministry never specialized departments managed to purchase substituting consumption。 or to link a number of external units, all lead to the rehabilitation costs are all linked by the Department of the project. ⑸ serious quality problems. serious losses Project Department, almost all relatively serious quality problems, resulting in rework, repair, It seems a repetition of construction, increase the costs of construction. For example, in the bridge construction, there is the basis sank, Pier deflect such phenomena. ⑹ construction equipment utilization rate is not high. Some of the projects undertaken projects a loss what to do, To ensure uninterrupted construction, acquisition or blind items transferred from other large equipment reserve, even bought some of the projects do not require the equipment, resulting in longterm suspension equipment. , Construction ⑺ unreasonable arrangements. During the construction process, the project was not in a reasonable allocation of manpower, materials, equipment and other resources. lea
