A Study on the Public Construction Project Cost-Saving Practice Information Provision Service Method

Cost saving in construction projects consists in building structures with the most economical method while satisfying the user requirements with regard to the features and quality. Cost saving through systematic cost management is required to improve the competitiveness in line with the changing construction environment. Organizations affiliated with the Ministry of Land, Infrastructure, and Transport are striving to save on construction costs by reviewing the economic efficiency of their designs, process management, and project management when implementing public construction projects. They are sharing the design value engineering (VE) results information among the public ordering agencies during the design stage, but the sharing of the cost-saving practices in the construction stage is still insufficient. This study presented step-by-step information systems development and service methods so that people can refer to and utilize cost-saving practices in similar construction projects while carrying out public construction projects. The results of this study are expected to contribute to more rational decision-making in and the higher investment efficiency of public construction projects through the analysis and provision of cost-saving cases information for each stage of the construction project life cycle, such as the planning, design, construction, and maintenance stages.
