  • Technological aspects of conventional demolition/deconstruction are discussed, and an economic analysis is performed on a case study, directly comparing these two options. This comparison illustrates that although deconstruction is not yet competitive with conventional demolition, within the conditions established in the study, some deconstruction scenarios do present economic advantages. In environmental terms, from a simplified life-cycle analysis (LCA) approach, it can be concluded that, with current techniques and transportation methods, only significant separation efforts that actually result in re-use of recycling of bulk aggregate materials may lead to sizable environmental impact reductions, compared to a conventional demolition scenario.
