There is growing need to improve the implementation of sustainable construction in Nigeria. The awareness of the costs and benefits of sustainable construction is a fundamental principle underlying the implementation. This study assessed the economic viability and societal impact of implementing sustainable development practices in the construction industry in Abuja, Nigeria. Through a comprehensive Cost Benefit Analysis (CBA) framework, the research investigated the long-term costs and benefits associated with sustainability practices in building construction. Data collection was done using mixed method approach. Corelational analysis was use to analyse data of existing datasets on economic indicators, environmental parameters, and social statistics. The study revealed a dichotomy in the construction professionals' stance toward sustainable development, with a high level of awareness but a disparity in actual implementation. The Relative Importance Index (RII) findings emphasize the importance of indoor ventilation, energy-efficient systems, and structured construction waste management. Findings from the research recommend deepening the awareness levels of the long term benefits associated with sustainable construction among relevant stakeholders. The research contributes to addressing the gap between booming construction activities in Abuja and sustainable construction practices, aiming to create a more environmentally friendly, economically viable, and socially responsible construction industry.
Key words: Sustainable Development, Cost Benefit Analysis, Associated Cost, Associated Benefits.
