In this research paper, the main causes and remedies to delays for building construction projects in Karachi are identified and ranked according to the viewpoint of all stakeholders using frequency indices. Furthermore, the ranking was tested statistically by using Analysis of Variance (ANOVA) and box plots. It was found that the perception of clients regarding causes of delays is different than other stakeholders. Whereas, consultant group's perspective about the remedies for delays was different than all others. Such studies have also been conducted in other regions of the world. However, a comprehensive review and comparison was not found in the existing literature. Therefore, the results were also compared with previous international studies conducted in other developing countries. It was found that the perception of local client group was greatly different in from that for other regions. On the other hand, the perception of contractors was found to be similar for local and other construction industries. On the basis of this study, it can be said the client group's perception is unique in Pakistan compared to other industry stakeholders, locally as well as internationally.
