Improvement of the Life Cycle Costing Method in Design Stage Using KBIMS Library

With the advent of the fourth industrial revolution, the construction industry has undergone a paradigm shift. The smart construction technology market is expected to grow 12% annually in developed countries due to advanced technology investments. It is expected that businesses requiring highly sophisticated technology, for instance companies that need their old facilities upgraded, will become the main focus of the market. As building information modeling (BIM) design is becoming mandatory, such as in the Korea Public Procurement Service, researches regarding building automation, construction, and operation integration management systems based on BIM are conducted. In addition, for construction projects of over 10 billion won, design value engineering (Design VE) implementation, including life cycle cost (LCC) analysis, is mandatory at the design stage to improve quality and reduce the lifetime costs of buildings. In this study, we propose an improvement plan for LCC analysis at the design stage using the KBIMS library, which is an open BIM library developed by the Korean government and research groups. We analyze the existing LCC method, KBIMS library, and attribute information, and model the process that is applied in the LCC analysis system. This is expected to complement the LCC analysis system and improve work productivity.
