Abstract: COVID-19 pandemic has created unprecedented disruption in project deliveries. This study aims to understand whether suppliers' distance and location significantly affected project delivery delays and rising costs during the COVID-19 pandemic. To understand whether the distance and location of suppliers have significantly affected delays in project delivery and rising costs, an independent t-test and ANOVA were used for assessing the differences in delays and rising costs between project organisations that have suppliers with different distances. Based on our study, it has been found that the location of suppliers had no significant effects on delays and rising costs of projects.

Keywords: COVID-19 pandemic; disruption of supply chains; project deliverables; project delays; project costs.
