Results obtained in this study highlighted lack of coordination, replacement of key personnel by clients and inadequate understanding of clients need as three major issues related to client which are responsible for changes in construction works. While delay in completion schedule, slower project progress and dispute between owner & contractor are as major parameters affecting schedule performance. For correlation analysis, it was found that lack of coordination between the parties has significant correlation with delay in completion schedule, and dispute between owner & contractor.
