Optimising sustainable deconstruction strategies for concrete structures: a multi-criteria decision-making framework approach

What is it about?

This study focuses on creating a structured approach to tearing down large concrete buildings in a way that minimizes environmental harm and maximizes the recycling of materials. The method helps construction companies and decision-makers choose the most effective strategies for dismantling concrete buildings, considering factors like cost, environmental impact, and material recovery. The research uses a decision-making framework that combines two popular methods—AHP (Analytic Hierarchy Process) and VIKOR—to evaluate different ways of deconstructing buildings. The study tested the framework on a real building to show how it can guide more sustainable practices in construction demolition. This framework can help governments, contractors, and policymakers choose deconstruction strategies that balance economic, environmental, and technical concerns, contributing to a more sustainable construction industry.
