Study Of Value Engineering's Application In Tunnel Construction Costs Controllment

It is difficult to control the costs of tunnel construction because of itstechnology economy characteristics such as large investment,long period,highrisk.Lots of problems in the tunnel construction enterprises areunresolved,whose creative power of value is far from enough. The enterprisesattach little importance to value and lack the scientific and handy costsmanagement system. Value Engineering, a scientific method which combinestechnology and economy ,is undoubtedly a useful tool to help the enterprisesachieve such goals.The construction enterprises can benefit from it in thedifferent phases of construction.Value.Engineering can bring down thecosts,raise the profits,optimize the management and accelerate technologyadvancement.So it's essential to popularize the application of Value Engineeringto tunnel construction enterprises,which will help to improve the value of theDroducts of tunnel construction enterprises.lt can also play a role in helpingcultivate the core competence of the enterprises and promoting the continuousdevelopment of the society as well as the national economy.Since Value Engineering is still in its infancy in our country,it hasn't been well-accepted by tunnel construction enterprises.Sometimes,it's even misunderstood.Therefore it's necessary to build a Value Engineering management system on the basis of theory and practice so that the tunnel construction enterprises can have a better understanding of Value Engineering, then they can further apply it spontaneously and skillfully to create new value and it can help to increase the core competence in this way.The thesis analyses the status and characteristics of the tunnel construction enterprises.,then build the value engineering management system in the prophase, metaphase and anaphase of the construction.The thesis concretely discuss methods and programs for the establish of target costs with the Value Engineering in the costs limitation distribution;expatiate the methods and programs with the Value Engineering in the construction organizing plan,material choosing,construction equipment choosing and construction management. The thesis set the scientific theory basis for the decision-making in the different phases of tunnel construction,so the whole project can becontrolled by the numbers.The thesis foretells the great social and economic benefits that Value Engineering will bring us. In addition,some potential directions of study in which value engineering can be applied are mentioned in this thesis too.
