Evaluating the impact of cost waste causes in residential buildings construction total cost

Cost increase is one of important factors that always have a negative effect on project success. Cost increase is divided in two parts: cost overrun and cost waste. Cost overrun is the difference between the actual and estimated cost of project and money waste is the cost that paid for non-value-add...
