Abstract

This paper presents development of a model to be used to select the best option for building replacement in public ownership such as public library, stadium, hospital and school buildings. Buildings life cycle management should be transparent and cost efficient. Hence, decisions taken during the life cycle of the buildings should be based on clear justification. One of the major issues in facility planning is to determine whether to rebuild or restore the existing facility. In fact, for government assets, they have to be economically managed by knowing the holding cost, so that it is viable to be retained in long run. The objectives of this paper were to establish relationship between replacement cost and cost decision making factors through the development of replacement cost model towards an economic efficiency for government buildings. Three stages of process were involved in this study. They are, stage 1, which explain on the significance factors of Cost Decision Making (CDM) and Replacement Cost (RC). It followed by exploration of the relationship between CDM and RC in Stage 2. Finally, the development of replacement cost model that expected to increase economic efficiency and transparency of building replacement. The results expected to provide a raw evidences to support a concept that refurbishment of existing building would be more benefit than replacement to the new ones. It is also expected that the results could be used by organizations especially for the decision makers as a guideline or tool to make a wise decision in building replacement related activities.
