Ibe, C. N. (2026) Optimising sustainable deconstruction strategies for concrete structures: A multi-criteria decision-making framework approach. International Journal of Building Pathology and Adaptation, 44(3), pp. 773-788. ISSN 2398-4708
Abstract
Purpose – This study proposes a multi-criteria decision analysis (MCDA) framework to optimise sustainable deconstruction strategies for precast concrete buildings. The framework aims to maximise material recovery, minimise environmental impacts and ensure cost-effectiveness, providing stakeholders with an evidence-based tool for decision-making. Design/methodology/approach – The framework integrates the analytic hierarchy process (AHP) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods to evaluate 18 deconstruction strategies across 4 categories: concrete component removal, reinforcement separation, structural dismantling and material recycling. A case study of a four-storey university building was modelled using DesignBuilder software to simulate material flows and assess performance metrics. Stakeholder input was used to determine criteria weights, balancing environmental, economic and technical dimensions. Findings – Selective removal strategies, particularly staircase dismantling (D3) and wall panel removal (D1), yielded optimal material recovery and cost efficiency while minimising environmental and safety risks. Scenario S1 demonstrated adaptability as an early-stage strategy for precast panel removal. Practical implications – This framework serves as a practical tool for contractors, policymakers and environmental agencies, enabling the prioritisation of deconstruction strategies that align with sustainability objectives. It supports global climate goals by reducing emissions and enhancing the value of recycled materials. Originality/value – This study advances sustainable deconstruction by integrating AHP and VIKOR into a cohesive MCDA framework. It offers a practical decision-making tool for contractors, policymakers, and environmental agencies, contributing new insights to the construction industry and supporting global sustainability goals.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
