4D modeling - the simulation and visualisation of the construction process - is now a common method used during the building construction process with reasonable support from existing software.
The goal of this paper is to examine the information needs required to model the deconstruction/demolition process of a building. The motivation is the need to reduce the impacts on the local environment during the deconstruction process. The focus is on the definition and description of the activities to remove building components and on the assessment of the noise, dust and vibration implications of these activities on the surrounding environment. The outcomes of the research are (i) requirements specification for BIM models to support operational deconstruction process planning, (ii) algorithms for augmenting the BIM with the derived information necessary to automate planning of the deconstruction process with respect to impacts on the surrounding environment, (iii) algorithms to build naive deconstruction activity schedules.
