This study examined implementation process of value engineering at the design phase (design VE) in Korea Highway Corporation. Using life cycle cost analysis (LCCA), this study identified a positive effect of the design VE with LCCA on economic efficiency. Korea Highway Corporation recognized the need of implementing design VE with LCCA and developed methods of establishing the LCC-effective optimum design for bridges. It reduced the cost of bridge construction in express highway, resulting in ￦ 7.56 billion of saving in 2005. Also, using design VE with LCCA, it became capable of evaluating the functions of a bridge and economic efficiency from the perspective of the total life cycle. Implementation of design VE with LCCA required the active participation of both team members of VE task force and engineers of strong specialities and also a systematically integrated information system. It was necessary for design VE with LCCA to be worked up the total construction projects and for user costs to be analyzed in order to execute LCCA. Channels for free communication and incentives for strong participation needed to be prepared for the stakeholders in highway construction, including VE task force team members and engineers. By improving the quality of laws and regulations in terms of design VE and LCCA, government- related organizations could elicit proper utilization of design VE and LCCA.
