ABSTRACT
Since 2019, the year of the COVID-19 outbreak, many businesses have been shut down across different industries and geographical locations, and the construction industry is one of those that has suffered more than any other due to its volatile nature. This study emphasizes the impact of COVID-19 on project management within construction companies and the ways it has affected the completion of projects. The literature review was provided with effective theoretical information regarding the research topic by highlighting key concepts, theories, and models after identifying crucial aspects that resulted in cost and time overruns in the context of UK construction projects. This study has been conducted as a primary qualitative method to gather firsthand data employing interviews with five construction project managers from the UK. The researcher has discussed interpretivism research philosophy, the inductive research approach, and explanatory search design and has conducted purposive sampling. In addition, primary qualitative data collection and thematic data analysis have been discussed in this study. The research has identified 10 types of themes focused on the transcript, which were developed through interviews. Further, a detailed comparative discussion was made on three top themes, which were based on cost overrun, and time extension of construction projects during COVID-19. The interviewees have outlined the significant impact of COVID-19 on supply chain management and the labor force. The multimethod approach helps in understanding the diverse point of view across different countries and geographical regions and finally reaching a conclusion with a comparative approach.
