Abstract

Globally construction works are suffering from several challenges. One of the major challenges is
changes during execution of the construction work. Changes exert several negative impacts on the project
performance. For effective project performance, it is necessary to understand the effects of changes. Hence,
this study investigated various effects of changes occurring in construction project. Investigation was carried
out quantitatively through questionnaire survey based on effect variables identified from review of literature.
It involved three categories as time overrun, cost overrun and quality measured with 48 variables. 100
questionnaire sets collected against 218 questionnaire forms distributed among the practitioners were
analysed statistically. From analysis results, it was found that cost overrun is major effect of changes
followed by quality and time overrun. Delay in completion schedule, slower project progress and dispute
between owner and contractor are reported as major drivers of time overrun. Top three variables of cost
overrun in cost overrun are increase the cost of the projects, interrupted cash flow and additional money for
contractor. While, major drivers of the quality in construction projects are rework of bad quality
performance, changes in materials specifications and changes in material types & specifications during
construction. These findings will be helpful for the practitioners in achieving project performance
