The state in which "the final cost of the project exceeds the original estimates" is referred to as "cost overrun." It is thought that there should be an average rise of roughly 33% in construction projects.

Describe the FIVE (5) variables that contribute to cost overruns in building projects and how the Value Management (VM) strategy can help to reduce the issue
