In the heart of Nigeria’s bustling construction sector, a groundbreaking study led by Dr. H. C. O. Unegbu of the Department of Mechanical Engineering at Ahmadu Bello University, is set to revolutionize how sustainability is approached in the industry. The research, recently published in the journal Discover Civil Engineering (translated to English, Discover Civil Engineering), delves into the intricate web of factors that influence sustainable construction practices, offering a roadmap for policymakers and industry stakeholders to navigate the complexities of environmental, social, and economic sustainability.
The study, which utilized Structural Equation Modeling (SEM), reveals that government policies play a pivotal role in driving sustainability outcomes. According to Dr. Unegbu, “Government policies are the linchpin in fostering sustainable construction practices. Our findings show that effective policies can significantly influence organizational culture, technology availability, financial implications, and stakeholder processes.”
The research analyzed data from 248 respondents across ten construction companies, uncovering substantial path coefficients that underscore the interconnected nature of these dimensions. For instance, the path coefficient for government policies influencing organizational culture was β = 0.45, indicating a strong positive relationship. Similarly, the impact of government policies on the availability of technology and expertise was even more pronounced, with a path coefficient of β = 0.58.
One of the most striking findings was the significant influence of organizational culture on sustainability dimensions. The study found that organizational culture significantly impacts the availability of technology and expertise, financial implications, and stakeholder processes. This highlights the critical role that company culture plays in driving sustainable practices. Dr. Unegbu elaborates, “An organization’s culture can either hinder or accelerate the adoption of sustainable practices. Companies that prioritize sustainability in their culture are more likely to invest in green technologies and engage stakeholders effectively.”
The study also derived a mathematical model for Sustainable Construction Practices (SCP), which is SCP = 0.01 + 0.5x + 0.3y + 0.2z, where x, y, and z represent environmental, social, and economic sustainability, respectively. This model underscores the interconnected nature of these dimensions and offers a practical tool for policymakers and industry stakeholders to measure and improve sustainability outcomes.
The implications of this research are far-reaching, particularly for the energy sector. As Nigeria continues to invest in infrastructure development, the findings provide a blueprint for integrating sustainable practices into construction projects. By emphasizing the role of government policies and organizational culture, the study offers a strategic approach to balancing environmental, social, and economic sustainability. This could lead to more energy-efficient buildings, reduced carbon footprints, and a more sustainable future for Nigeria’s construction sector.
As the construction industry in Nigeria and beyond looks to the future, this research serves as a critical catalyst for change. It underscores the need for robust government policies, a strong organizational culture, and a holistic approach to sustainability. With these elements in place, the construction sector can pave the way for a more sustainable and resilient future.
The study, published in Discover Civil Engineering, is a significant contribution to the field, offering a comprehensive framework for sustainable construction practices. As the industry continues to evolve, the insights from this research will undoubtedly shape future developments and guide stakeholders towards a more sustainable path.
