ABSTRACT

ABSTRACT The Life Cycle Cost (LCC) concept enables costs prediction throughout the life cycle of building projects. The scientific community and the practitioners of the Architecture, Engineering and Construction (AEC) sector have been developing this concept for the past decades. Presently, it is encouraged by several international and regional standards, procurement guidelines and regulations applicable to this same sector. However, public procurers of building projects still face difficulties regarding the costs estimation and time ratios of systems and components over the life-cycle of building facilities. It has been recognized that dedicated public databases with the adequate quantity and quality of economic data are needed in this regard, and that the existing ones often present problems such as those of inadequate data granularity, incompleteness and inaccuracy or data structures with formats that make comparison and extrapolation difficult. The present document discusses a framework for economic data collection throughout the whole life-cycle of building facilities (LCC-EDC), which may contribute to address these problems. This proposal seeks to harmonize and empower previous efforts in the realm of LCC applications in the AEC sector, enabling information exchanges according to a standardized taxonomy that can fulfill gaps and limitations of current practice. A case study, related to buildings, is also described and discussed as to show the potential of the proposed framework for widespread LCC application.
