With the increasing stock of aging structures, the strategy to model and analyse the retirement of deteriorated structures is becoming a challenging research field. As the converse of construction of new projects, the retirement of constructed facilities puts forward some new management and economics themes as well as environmental issues or adds some new contents even though the same issues are faced in construction. This research aims to model and analyse the maintenance and demolition activities of constructed facilities from economic and environmental perspectives. Both cost and carbon dioxide of maintenance and demolition activities are formulated based on those of construction activities and applied to an empirical study on deteriorated bridges. Further modelling and analysis is investigated to elaborate the demolition stage of a structure. The developed modelling and analysis methodology may enable the decision maker to determine the retirement strategy for a deteriorated structure.
