Contributions of Quantity Surveying Professions Towards the Development of Sustainable Construction Industry in Nigeria
Abstract
The present study adopted a quantitative survey research design to investigate the contributions of quantity surveying professionals towards the development of a sustainable construction industry in Nigeria. A structured questionnaire was designed to collect data from 120 respondents, representing a diverse sample of quantity surveyors from different regions and sectors. The data were analyzed using SPSS26, enabling rigorous statistical analysis to derive meaningful insights from the collected data. To test the hypotheses of this study, t-tests were conducted to assess the significance of differences in quantity surveyors’ awareness and level of integration of sustainability principles in construction projects. The findings revealed that a significant proportion of quantity surveyors exhibited a high level of awareness of sustainable construction practices. However, the level of integration of sustainability principles in projects varied among respondents. Notably, quantity surveyors with more experience and exposure to sustainable construction projects demonstrated a higher level of integration. The study’s results highlighted the importance of promoting further education and training for quantity surveyors to enhance their understanding and application of sustainable construction practices. It also emphasized the need for continuous professional development to keep quantity surveyors abreast of the latest sustainable technologies and strategies. In conclusion, the study’s findings underscore the role of quantity surveyors in driving sustainable construction practices. By improving their knowledge and integration of sustainability principles, quantity surveyors can contribute significantly to more environmentally responsible and resource-efficient construction projects in Nigeria. Â Based on these findings, it is recommended that industry stakeholders and professional bodies collaborate to develop comprehensive training programs and workshops focused on sustainable construction practices. Additionally, policy interventions should encourage the incorporation of sustainability criteria in construction project evaluations and tendering processes, emphasizing the importance of sustainability in the construction industry. Overall, this study contributes valuable insights into the awareness and integration of sustainable construction practices among quantity surveyors in Nigeria and provides a foundation for advancing sustainability in the country’s construction sector.

CHAPTER ONE
INTRODUCTION
Background of the Study
The construction industry plays a vital role in the economic development of Nigeria, contributing significantly to the Gross Domestic Product (GDP) and creating employment opportunities for its citizens (NBS, 2020). However, the industry’s growth has raised concerns about its impact on the environment and the depletion of natural resources. Sustainable construction practices have become a global imperative to address these challenges and ensure the industry’s long-term viability (UNEP, 2019). Sustainable construction involves the use of environmentally friendly materials, energy-efficient technologies, and socially responsible practices to reduce negative impacts on the environment and society (CIBSE, 2021).
In recent years, there has been a growing awareness of the need for sustainable practices in the construction industry in Nigeria (Oyedele et al., 2022). The country faces significant environmental challenges, including deforestation, air and water pollution, and waste generation (Ezema et al., 2021). The construction sector, being a major consumer of natural resources and a significant contributor to greenhouse gas emissions, has come under scrutiny for its role in exacerbating these issues (Oluwunmi et al., 2020).
The quantity surveying profession is a critical stakeholder in the construction process and plays a central role in managing costs and contracts, providing expert advice on project finance, and ensuring cost-effectiveness throughout the construction lifecycle (QSRBN, 2021). Quantity surveyors are ideally positioned to influence decision-making processes that impact sustainability in construction projects (Akinpelu et al., 2021). They can contribute to sustainable construction by promoting the use of eco-friendly materials, implementing energy-efficient designs, and optimizing resource management (Odeyinka et al., 2019).
However, despite the potential of quantity surveyors to drive sustainability, their current level of awareness and understanding of sustainable construction practices in Nigeria is relatively unknown. Past studies have suggested that there may be a lack of knowledge and expertise in this area (Ademoroti et al., 2019). Therefore, investigating the level of awareness and understanding among quantity surveying professionals becomes crucial in developing targeted interventions to bridge existing knowledge gaps.
Furthermore, while some efforts have been made to promote sustainability in the Nigerian construction industry, its integration into the mainstream practices of quantity surveyors remains limited (Fatile et al., 2022). This study seeks to identify the current roles and responsibilities of quantity surveyors concerning sustainable construction practices. By understanding the extent to which sustainability is integrated into their work, stakeholders can identify areas for improvement and develop strategies to enhance their contributions to sustainable development.
In addition to assessing awareness and current practices, it is essential to explore the potential barriers and opportunities that quantity surveyors face in contributing effectively to the development of a sustainable construction industry in Nigeria. Barriers could include a lack of institutional support, insufficient training and education, and resistance to change from traditional practices (Adenuga et al., 2020). Identifying these obstacles will enable policymakers and industry players to devise targeted strategies to overcome them and create an enabling environment for sustainable construction practices.
Consequently, the construction industry in Nigeria faces significant challenges regarding sustainability, and there is a need for concerted efforts to address these issues. Quantity surveyors, as professionals central to cost management and project execution, can play a pivotal role in promoting sustainable construction practices. However, their contributions are contingent on their level of awareness, integration of sustainability practices, and the ability to overcome existing barriers. This study aims to shed light on these critical aspects and provide valuable insights to drive the construction industry’s sustainable development in Nigeria.
Statement of Problem
The Nigerian construction industry is facing multiple challenges that hinder its progress towards sustainability. One of the primary concerns is the inadequate attention given to environmental and social aspects of construction projects. Despite the growing global emphasis on sustainable construction practices, there is limited awareness and understanding of these practices among quantity surveying professionals in Nigeria. This lack of awareness could impede their ability to incorporate sustainable principles into their decision-making processes, leading to missed opportunities for positive environmental and societal impacts.
Furthermore, the current roles and responsibilities of quantity surveyors in the construction industry may not fully align with sustainable development objectives. Traditional cost-focused approaches may prioritize short-term cost savings over long-term sustainability considerations. This approach could result in inefficient use of resources, generation of excessive waste, and increased environmental degradation.
Another challenge pertains to the barriers that hinder quantity surveyors from actively contributing to sustainable construction initiatives. These barriers may include inadequate training and education in sustainable practices, limited access to relevant information and resources, and a lack of support from stakeholders and industry players. Overcoming these barriers is crucial for empowering quantity surveying professionals to play a more proactive role in advancing sustainable construction practices in Nigeria.
Addressing the aforementioned issues is of utmost importance to foster the development of a sustainable construction industry in Nigeria. By exploring the level of awareness, understanding, and integration of sustainability among quantity surveyors, as well as identifying potential barriers, this study seeks to provide valuable insights and recommendations to promote sustainable practices and enhance the profession’s contributions to sustainable development.
