Inspect the rationality and implementation of techniques anizational measures and management plans.(3) paring lower cost of the same period last year. Aanalyze causes and propose the improving direction. (4) Comparison between engineering units in costcutting. Identify the units costreducing, which finishes projects, with a view to further cost analysis. Cost analysis of unit project. Comprehensive analysis only understand project cost overruns or lower. If we want to get more detailed information, each cost item analysis of unit project is needed. Analysis mainly from the following aspects: (1) Materials cost analysis. From the view of material stock, production, transportation, inventory and management, we can analyze the discrepancy impact of material price and quantity, the costreducing effectiveness resulting from various technical measures, the loss from poor management. (2) Labor cost analysis . From the number of employment, hours of use, ergonomics, as well as wage situation, we can identify the savings and waste during labor use and fixed management. (3) Construction machinery cost analysis. From the construction options, mechanization degree, mechanical efficiency, fuel consumption, mechanical maintenance, good rates and utilization, we can analyze the yield and cost discrepancy of fixedclass ergonomics, the cost of poor classes, focused on improving mechanical utilization efficiency and waste caused by poor management. (4) Management cost analysis. From construction task and anizational staffing changes, nonproduction personnel changes, as well as other expenditure savings and waste, we can analyze management fees and justify the rationality of expenditure. (5) Technology anization measures implementing analysis. It can increase experience for future establishment and implementation of technical anization projects. (6) Other direct costs analysis. Focus on the analysis of second removal and water, electricity, wind, gas and other expenses situation during construction. 2. The shortings of costcontrol methods At present, domestic construction projects costcontrol methods have played a significant role for Chinese construction industry and construction enterprises to reduce cost and gain sustainable development. However, we should be aware that these methods exist some shortings as follows: Lack of systemization. Presently, the cost control of construction enterprises is a simple control on cost. In fact, project cost control is closely related with project plans and progress, quality and safety. Therefore, cost control should include abovementioned elements. Lack of real time Modern project management is increasingly tending realtime management and forwardlooking management, paying more attention to promptly identify and solve problems, emphasizing as much as possible to identify and solve problems before problems occur. The current control system is to control after problems occur, which can39
