【正文】 Fourth, ine, the calculation of the costs of inaccurate, the cost is not real, and losses are not allowed。 Second, currency and capital management, the creation of a number of bank account deposits. But without timely check cleared lead to bank deposits and cash accounts are inconsistent. hide the huge cost of bank deposits and cash balances Lane。 Construction of the manufacturing arrangements unreasonable to step in to plete the actual conduct of the second, three plete, the resulting redone, and so on. ⑻ More accidents. the loss of the item, Most of the projects have occurred in the Department of varying degrees of security incidents and minor injuries affected employees work injuries have affected staff work, Also the cost of medical expenses, but can also enable the staff of physical and skills decline, reduced labor and labor efficiency。 or the extensive use of subteams, resulting in super funds arrears subteams such phenomena occurring。 serious or even false invoices for reimbursement of materials. Projects not on the scale expected, the number of construction workers to be the number, the result of multiple materials is not a waste of throwing at the site, the site is being sold secretly staff, Many can recall no more waste management. 1823 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. For example, Some contracting for the pletion of the mission and the number of wages, but the consumption of materials and equipment use, maintenance is not explicitly required to form the contracting notincluded, the surplus excluding packet loss, some contracting program, though reasonable, but pricing is not timely, not in accordance with the contract or program honored so that the contractor could not continue. ⑷ Subloopholes. Projects contingent on the labor subcontractor, the contracting notincluded, to allocate more projects。 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. With mechanical equipment failure analysis is not objective and subjective reasons, not to pursue the responsibility of the parties, have bad information on the exchange, no other information on. TWA did not undergo a rigorous examination on the induction training mechanical damage to the nonnormal, impact of the construction progress. In summary, the current project of cost management, accounting only after the accounting, rather than advance the prevention and control things. The reasons are : lack of cost awareness. simply that the cost of management is the financial sector or the superior leadership, have nothing to do with them. only focused on the production tasks are pleted and contracting profit and loss, the groups have 1723 a negative effect. Therefore, project to mobilize the full participation of the Ministry of cost control, deepening of the project cost management imperative. 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 anizations 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。 can be used for lowcost trades and the use of subjects of labor costs. To take care of relations, sensibilities and TWA also retained his spare time. Workers can be indifferent to the production and operation, but the monthly wages, allowances, and bonuses can spend less. 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, and some kind of engineering materials and book a difference to thousands of dollars, tens of thousands or even hundreds of some of its few. 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。 informative。 only achieve cost control project aims to strengthen the management of construction project can be meaningful. Construction of the project cost control of construction reflects the nature of project management features, and represents construction project management at the core. Construction of the project cost control of construction project management performance evaluation of the objectivity and fairness of the scale. 5. Strengthen project cost control practical significance strengthen project cost control railway construction enterprises out of their predicament, the need to increase revenue. At present, the railway construction enterprises just into the market, to participate in market petition, will face a tough test of the market. Now the construction market liberalization, implement bidding system, and the strike has very low weight, To create efficiency is the only way to strengthen internal management and improve their internal conditions, internal efficiency potentials. Therefore, the strengthening of project cost control is a very realistic way. Strengthening Project Cost control is adapt to the market petition, and strengthening internal management to the needs of their work. With the railway enterprise39。 paid attention to quality control to eliminate redone, shorten the acceptance and reduce expenses。 Finance Ministry in charge of the project39。 engineering technology department should ensure the quality, Regular tasks to plete as much as possible under
