Waste effects inter-reliant with productivity, the Waste measurement is essential in the management of production systems, because it is an effective way to evaluate their performance. Maine aim for this paper is diagnoses the waste time factors and examined to eliminate them in the implementation ‘the tests assess the performance of the process accomplished by finding the waste time on the two case studies, the observations have been taken in Baghdad using forms developed by researchers specifically designed based on the fundamentals of work-study methods and Work measurement techniques including (Activity sampling observations sheet, the flow process chart, and foremen survey form.) the wasted time causes defined clearly inclusion the performance of general efficiency also determining the Invaluable and unnecessary activities ratio that contribute in the waste of implementation a general regression model had been made for these factors showing the power of their association. The calculations shown the Mismanagement of the site and Choosing an inefficient contractor is most significant. while the conduct of activities the direct work is 56%, and the unnecessary activities by 25.75%, that’s the activity type should target for mitigation to increase the efficiency of the construction process from Wasted Tim reduction.
