Development of a software tool for the optimal dismantling of buildings

Abstract:In this paper a methodology and a computer based planning and optimisation tool for the elaboration of dismantling concepts for buildings is presented. This system enables planners and project managers to evaluate different strategies for cost and time efficient dismantling and recycling of buildings, with regard to resource constraints. Based on databases which comprise of bills of materials, data on dismantling techniques, construction elements, building materials, precedence relations, resources and dismantling costs, dismantling-networks are developed. Optimal dismantling strategies are evaluated by using a scheduling model, linked to the planning tool. Results show that with the help of this software tool the duration of dismantling and the dismantling and recycling costs can be reduced considerably. The developed concept was applied to two buildings, located in Germany and France are shown. These projects show that by the help of the developed tools up to 94% of all building materials can be recycled, and in some cases the costs of dismantling are lower than those for demolition.
