Study On The Cost Control In Earlier Stage Of Highway Construction

The investment decision stage and design stage as two main parts of preliminary work have great effect on the cost control of highway construction.At present,highway construction funds is relative shortage,how to control the preliminary cost effectively have great significance for the future development of highway construction.Road construction projects with the characteristics of large-scale,long construction period and huge investment.At first,the article analyzed the investment estimates in the preparation of project proposals and feasibility study at the investment deciding stage.It introduced turnover rate of funds and ratio estimation method.The article with practical engineering analyzed the engineering geological investigation impact on project cost in the decision stage of highway construction.The specific content of highway design includes line,roadbed,bridges,tunnels, and transport interchange facilities engineering design along.This article mainly analyzed the road,roadbed,bridges impact on the cost control of highway construction at design stage.It summed up the major initiatives to reduce the cost in design of highway projects.In highway design,optimization and optimization program is the key to cost control.It introduced the minimum cost method and multi-objective optimization in this paper,and proposed the selection and optimization of design using of value engineering in order to obtain the best possible combined effect,in which optimization of value engineering to design life-cycle cost design of the pavement structure were demonstrated as an example.It carried out Limits design and standardization design at design stage,in order to shorten the construction period to reduce the project cost.For a large number of uncertain factors on the impact of project cost at design stage,put forward a fuzzy comprehensive evaluation method in the design of the application.Finally,the article analyzed the cost control in the feasibility study and preliminary design of a highway construction in Henan.
