Research On Cost Prediction Of Large And Medium-sized Maintenance Of Shanxi Provincial Main Highway

At present,the investment mode of highway maintenance is required to reform in our country.The ration maintenance and gauge&payment should be pushed to implement across-the-board.But the existing cost management method of cutting lump-sum of Shanxi provincial highway maintenance is hardly suitable for the requirements of reform.Therefore,the new cost management of highway maintenance should be excogitated as soon as possible to satisfy the reform requirements of maintenance marketization.Firstly,the highway maintenance is defined by the recommended of the Standing Conference on International Highway Association in 1983,and the project cost is expounded from the perspective of owners and the market in terms of transactions.The paper makes it clear to the cost management character and connotation of highway maintenance.Based on summarizing the research of the cost management of highway maintenance at home and abroad,the problem of the current cost management of highway maintenance is pointed out.Through analyzing the demand for the cost management of highway maintenance under maintenance marketization. The basic orientation of marketization reform for the cost management of highway maintenance is definite to be "the uniform quantity,the direction price,the competition cost",which is propitious to put into practice the ration maintenance and gauge&payment across-the-boaxd.Finally,the main factor of cost prediction is determined by analyzing the composition of budgeted cost of highway maintenance. Consulting the way of highway cost management,the method of maintenance project budget based on the rations of maintenance projects is designed,from the angles of which highway maintenance management department strengthen cost management,in order to actualize the ration maintenance and gauge&payment across-the-board,and push the system of maintenance expense.The paper has achieved to ensure the integration between contract price and the bill of quantity system in according to highway projects quota.At the same time that the forecast achieves optimal to improve the allocation of highway maintance funds and project audit results,and the use of funds highway maintance and serviceable life.Through clearing up the relation between the plan of maintenance investment,the cost of the installation and construction,and the cost of roadway project,and integrating with characteristics of large and medium-sized maintenance engineering,the each cost management system of large and medium-sized maintenance engineering is set up from the viewpoint of highway maintenance investment management and price management.Finally,the paper evaluates the application of the mode of cost prediction on maintenance engineering.The application is based on tbe verification that combines the data of large and medium-sized engineering in ShanXi's eight areas over the years.The accuracy reach to the requirements.The modle of cost prediction meets a strong practicality,and provides a scientific basis for prediction the future works of large and medium-sized maintenance engineering.
