Abstract
The limited awareness and adoption of deconstruction practices in Nigeria's construction sector contribute to excessive waste and resource inefficiency. this study systematically identifies and evaluate effective deconstruction techniques focusing on maximising material recovery, reducing environmental impact, and enhancing sustainability. a comprehensive literature review informed the development of a questionnaire survey distributed to construction professionals in Nigeria. the data were analysed using statical tools such as percentages, frequencies, and the Kruskal- Wallis test. the results indicate that selective deconstruction, component reuse, manual disassembly, material segregation, and mechanical deconstruction are the most effective techniques. significant differences in opinions were found among construction professionals on three out of fifteen identified techniques. By highlighting efficient methods for building deconstruction, this study provides a framework for construction professionals, policymakers, and stakeholders to optimise materials reuse and recycling. The findings promote a shift from traditional demolition to eco-friendly deconstruction, supporting the circular economy in the construction sector.
