Sustainable practice is considered a significant practice in modern construction for infrastructure development as it promotes economic growth and improves quality of life. Despite the importance of sustainable practices in construction, few studies have explored the implementation of these practices in low-income countries like Malawi. Therefore, this study aims to assess the extent of the implementation of sustainable construction practices (SCPs) in building infrastructure projects in Malawi. Following an in-depth literature review, 22 sustainable construction practices and 13 drivers were identified. A survey of 193 construction professionals was conducted, and the data were analysed using descriptive statistics and the Relative Importance Index (RII). The findings revealed that economic practices such as efficient allocation of resources, use of quick construction tools and a coordinated supply chain in the construction process are widely implemented with emphasis on the economic aspect of sustainability for infrastructure projects in Malawi. The study further identified global trends and industry standards, social and health benefits, market demand and awareness and access to green technologies and innovation as the main drivers for adopting and implementing SCPs in Malawi. This study provides policymakers and stakeholders with valuable insights to develop policy regulations that would improve the sustainability performance of infrastructure projects.

The implementation of sustainable construction practices (SCPs) is recognised as a significant approach to enhancing the sustainability performance of infrastructure projects globally. However, the adoption and implementation of SCPs in low-income countries like Malawi remain in its early stages due to several challenges. This study provides an empirical analysis of the challenges hindering the implementation of SCPs in building infrastructure projects in Malawi. The study employed a systematic review and a quantitative method with a questionnaire survey among 193 construction professionals within the Malawian construction industry. The data was analysed using descriptive statistics, one-sample t-tests, and exploratory factor analysis. The results revealed that higher costs of sustainable building processes, lack of information on sustainable building products, and higher costs of sustainable building materials are the major challenges for SCPs implementation in Malawi. The factor analysis further revealed that institutional limitations were the most critical, followed by inadequate technical experience, while financial constraints were the least significant challenge. These findings emphasise the urgent need to provide financial incentives, capacity-building programs for industry professionals, and supportive regulatory frameworks to facilitate the implementation of SCPs. This study provides practical insights for policymakers and stakeholders to enhance the sustainability of infrastructure projects in the construction sector.

The implementation of sustainable construction practices (SCPs) has been identified as a significant approach to promoting and enhancing the sustainability performance of infrastructure projects globally. However, the adoption and implementation of SCPs in low-income countries like Malawi is still in its early stages and has faced several challenges. Therefore, this study aims to provide an empirical analysis of the challenges hindering the implementation of SCPs in building infrastructure projects in Malawi. The study employed a systematic review and a quantitative method with a questionnaire survey among 193 construction professionals within the Malawian construction industry. The data was analysed using descriptive statistics, One-Sample t-test and exploratory factor analysis. The results revealed that higher costs of sustainable building processes, lack of information on sustainable building products, and higher costs of sustainable building materials are the most critical challenges to the implementation of SCPs in Malawi. The factor analysis further revealed that institutional limitation was the most critical component, followed by inadequate technical experience, and the least critical component was financial. This study provides practical insights for policy reforms, robust regulatory frameworks, and well-equipped institutions with the necessary expertise to promote the widespread adoption and successful implementation of SCPs in the construction industry.
