Research on Application of Entire Life-cycle Value Engineering in City Railway Transportation Project

Based on the status of application of value engineering in construction projects, through orientation for value object of entire life-cycle periods, this paper expatiates the implementation of entire life-cycle value engineering in city railway transportation project, systemically brings forward object selection, function analysis, function evaluation, scheme innovation and thought of choice of excellence of entire life-cycle value engineering in city railway transportation project, focuses on using lower entire life-span cost to realize final functions and to create the largest economic benefit, environmental benefit and social benefit.
