Abstract

This study explores the adoption and effects of innovative materials and advanced technologies on sustainable construction practices in Nigeria. Employing a mixed-methods approach, the research integrates quantitative surveys and qualitative interviews to collect comprehensive data from 255 construction professionals, achieving an 85% response rate. The findings indicate that recycled materials and green concrete are the most frequently utilized innovative materials, primarily due to their environmental advantages and cost-effectiveness. Building Information Modeling (BIM) and prefabrication emerge as the most widely adopted advanced technologies, enhancing efficiency, reducing waste, and improving project quality. Additionally, regression analysis reveals the complex nature of adopting sustainable construction practices, with cost emerging as a significant barrier for many firms. Despite these positive developments, challenges such as high initial costs, lack of awareness, insufficient regulatory support, and limited availability of sustainable materials impede wider adoption. The study highlights the necessity for targeted interventions, including financial incentives, stronger regulatory frameworks, and comprehensive education and training programs, to foster sustainable construction practices. The findings have substantial implications for policymakers, industry professionals, and researchers, offering a foundation for future research and practical strategies to advance sustainability in Nigeria's construction sector.

Abstract

This study investigates the determinants of sustainable construction practices in Nigeria, focusing on the roles of regulatory frameworks, financial incentives, organizational readiness, and awareness and knowledge among stakeholders. Utilizing a cross-sectional survey design, data were collected from 255 experts in the construction sector, consisting of architects, project managers and engineers. The analysis utilized Structural Equation Modeling (SEM) to explore the direct and indirect effects of these factors on the sustainable construction practices adoption. The findings reveal that awareness and knowledge have the most significant impact, highlighting the critical need for education and information dissemination in advancing sustainability. Additionally, robust regulatory frameworks and financial incentives were identified as crucial enablers, facilitating the implementation of sustainable practices by setting standards and reducing financial barriers. Organizational readiness, encompassing leadership support and resource availability, also emerged as a key determinant, mediating the effects of policies and incentives. The study concludes that a multifaceted approach involving strong policies, financial support, and enhanced organizational capacity is essential for promoting sustainable construction in Nigeria. These findings are valuable guide to policymakers, industry stakeholders, and educators in their efforts to foster an environmentally sustainable construction sector.

Abstract

This research examines the influence of green building certifications on construction practices within Nigeria, concentrating on certifications such as LEED, EDGE, and BREEAM. Through a comprehensive review of literature spanning from 2015 to 2023, the study assesses the adoption of these certifications, the resulting changes in construction methodologies, and the economic and environmental impacts observed. The findings highlight a modest but increasing uptake of certifications, largely driven by adherence to international standards and emerging local efforts. In Nigeria, buildings that have achieved certification demonstrate notable advancements in energy efficiency, water use reduction, and waste management, contributing to greater sustainability and reduced operational expenses. Nonetheless, challenges such as substantial initial costs, a lack of adequately trained professionals, and insufficient governmental policies continue to impede progress. The research underscores the importance of enhanced governmental intervention, greater public education, and the growth of local industries focused on sustainable building materials. Upcoming research should explore the extended financial advantages of sustainable building methods, the challenges hindering their widespread implementation, and conduct comparative studies with other developing nations. This research provides important knowledge for policymakers, developers, and other key players dedicated to promoting eco-friendly building practices in Nigeria, aligning with international sustainability goals

Abstract

This study develops a tailored sustainability assessment framework for Nigerian mega projects. The framework is applied to four diverse case studies: a highway expansion, an airport terminal, a renewable energy project, and a residential housing development. Results show that the renewable energy project achieved the highest sustainability score due to its superior environmental and economic performance. In contrast, the highway expansion project ranked the lowest, primarily because of its significant environmental impact and limited community engagement. Key findings emphasize the critical role of community engagement and lifecycle costing in achieving sustainable outcomes. Projects that incorporated inclusive planning and long-term financial strategies performed better overall. However, the study also identifies significant barriers, including weak regulatory enforcement and monetary limitations, which restrict the adoption of sustainable construction practices. The research highlights the need for localized sustainability frameworks in developing countries, as international models like LEED and BREEAM may not fully address context-specific challenges. This framework provides a valuable tool for policymakers, project managers, and stakeholders to enhance sustainability in large-scale infrastructure projects and support long-term development objectives.
