【正文】 ost control in many ways, this highlights deviation analysis. Deviation refers to the actual value of the construction costs with the planned value of the difference. Deviation analysis available Bar Graph method, the form, method. (1) Bar Graph method is different TransverseLine marking the pletion of the project has been the construction costs, End to construction projects have been pleted and cost (the costeffective construction, TransverseLine length is proportional to the amount of their cases. Bar Graph with image, audiovisual, very clear advantages, It can accurately express construction cost deviations, but one can feel the gravity of deviation. However, this method of information below. (2) Form method is error Analysis of the most monly used method, it will project code name, Construction of the cost parameters and construction cost deviation integrated into the number one form, and in the form of direct parison. As the deviations are shown in the table. Construction costs makes integrated managers to understand and deal with these data. flexible, applicability。 informative。 forms can be 第 4 頁 共 33 頁 handled by puter, thus saving a large amount of data to deal with the human, and greatly improve speed. (3) curve is a total construction cost curve (S OK curve) for the partial construction costs A differential analysis methods. a figure which indicated the actual value of the construction cost curve, p. construction cost of the scheme said the value curve, The curve between two vertical distance between construction cost deviation. The method used is the same image analysis, and visual characteristics, But this is very difficult to direct for quantitative analysis of quantitative analysis can play a role. 7. Currently construction enterprise project cost control analysis problems and the causes of the current project implementation After the restructuring projects implemented five responsibility for the costs, 100 of responsibility for the content of the output value of wages and contracting indicators Kau various forms of economic management contract responsibility system. Construction projects in the Ministry of Production and quality aspects of the rapid progress. But beyond doubt is just working, regardless of the mode of production accounts still exist. Specific indications : 1. in the use of labor, not by post, according to the actual needs staffing. artificially expand the expenditure of funds. 2, material management, can be simplified to what extent on what is the level of simplification, operational staff only to facilitate easy and timely withdrawal credit card. Consuming the works, the procedure is inplete. not fixed by the material. placing arbitrary site materials, engineering materials stolen have occurred from time to time。 Consuming accessories not review, bad on the other, very few people to repair。 fill empty fuel consumption result was secretly putting the oil sold. 3. Construction machinery efficiency is not high (example : Monthly leasing machinery and equipment), less to him, usually poor maintenance. TWA did not undergo a rigorous examination on the induction training mechanical damage to the nonnormal, impact of the construction progress. 第 5 頁 共 33 頁 Project Department analysis of the reasons for the losses as a project of building products Commodities direct producers, both under the contract and construction drawings, selfregulating organizations of the construction authority, Construction of that arrangement, the deployment of personnel, materials, equipment parts procurement, custody, use, consumption, safety, Quality of management with a measure of autonomy。 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. 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. ⑶ contract measures are inplete. Projects within the ranks of the contract is not be supporting management measures implemented after contracting loopholes 100, resulting in cost overruns. ⑷ subloopholes. Projects contingent on the labor subcontractor, the contracting notincluded, to allocate more projects。 or subunreasonable price。 or the extensive use of subteams, resulting in super funds arrears subteams such phenomena occurring。 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. 第 6 頁 共 33 頁 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 ite
