Purpose Covid-19 pandemic have raised serious health concerns, work disruptions and job loss. Thus, Nigeria’s Covid-19 challenges can hinder project performance in the construction sector. By integrating the principle of sustainable construction, it can minimise the environmental and socio-economic impact of Covid-19. This research therefore aims at developing strategies to achieve sustainable project performance in the post-Covid era in Nigeria. Design/methodology/approach A qualitative research method was used. Data was collected from 13 stakeholders in the built environment. Percentages and thematic analysis were used to analyse data from the interviews. Findings The study reveals that stakeholders are encountering operational and financial challenges: Increased price of materials, labour and material shortage and project delays were key operational challenges. The financial challenges were related to increased construction cost, reduced profit and payment delays. To address these challenges, the study developed managerial, contractual and governmental strategies: Market survey and bulk purchase, remote working and adherence to Covid-19 protocols were among the key managerial strategies. For the contractual strategies: contracts reviews, smart contracts, working overtime and night shift were developed, while governmental strategies included provision of funds, loans and incentives for workers. Originality/value The study deduced that while environmental sustainability was employed to address the Covid-19 challenges, the economic and social aspects were found to be under-utilized. Therefore, the study concluded that a holistic application of environmental, economic and social sustainability themes while incorporating managerial, contractual and governmental strategies is significant for achieving sustainable project performance in the post-Covid era in Nigeria.

Despite garnering increasing attention, the fifth Industrial revolution (IR 5.0) remains unexplored in Nigeria. This study therefore evaluates IR 5.0 application in the Nigerian construction sector, with a view to strategizing pathways to enhance its application for a sustainable built environment. A qualitative research approach was applied to elicit response from professionals in Nigeria. Percentages and thematic analysis were used to analyze the result. The result shows that a foundational understanding of IR 5.0 exists. However, varied interpretations of the concept impedes its awareness. Key challenges were found to include poor infrastructure, high cost of technology, lack of sufficient training opportunities, and the absence of government policies and incentives. Altogether, this have resulted in a rather limited application of IR 5.0. Hence, the study strategizes that increased awareness, infrastructural and technological development, collaboration, and training programs can play a unique role in enhancing IR 5.0 application in the Nigerian construction sector. The paper’s contribution to knowledge lies in providing a holistic insight on the emerging trends of IR 5.0 in Nigeria. Empirical evidence supports a promising foundation for IR 5.0 to build upon in sustainable materials, renewable energy systems and artificial intelligence towards a more sustainable built environment in Nigeria.
