Cost Analysis Of The Life Cycle Management For Highway Engineering In The Design Stage

In recent years,China's economic and social development has entered a new historical period,and transportation has also had a new development momentum.The development of China's expressway industry has gradually stabilized,and its future development also has good prospects.At present,the design of expressways mainly has problems such as indulging in the use of high-standard design,waste of resources,over-emphasis on construction costs,over-emphasis on explicit short-term gains such as explicit costs and return on investment,and insufficient design in the early stage.In this paper,firstly,the theory system of highway engineering design budget preparation and cost theory is sorted out theoretically,Long-term use of engineering quota system in China to achieve engineering valuation.With the wide application of new highway technologies,highway engineering construction projects have undergone major changes from design concepts and construction standards.The current pricing basis for the Ministry of Highways has not been able to meet the needs of existing highway construction management,and the new requirements of modern engineering construction cost management are combined.Then,based on the study of highway engineering design budget preparation to maximize the life cycle benefit,the cost control of highway engineering construction design stage is studied.Many existing problems are analyzed in detail,including concept,organization,scheme and other aspects.During the design phase,it plays a crucial role in cost control.Taking WG expressway project as an example,the paper analyzes and draws lessons from the experience.Based on the concept of life cycle cost,the whole process of analysis is carried out,and the theory is used to analyze the calculation results of the pre-cost,construction cost,operation cost and social cost of the expressway.Through calculation and analysis,the life cycle cost can be used to analyze the cost of the highway engineering design phase in an all-round way,and lay a solid foundation for selecting the appropriate design.At the same time,we can see the shortcomings of the highway project budget and the current cost control in the design phase.It is proposed to use the full life cycle cost theory to incorporate the budget planning to guide the highway engineering design work.
