Optimal Responsibility in Causing of Delay for Construction Projects in Iraq by Using ANP Technique

The construction projects suffer from the problem of delay in completion due to many factors that lead to slow implementation of time and quality required, in addition to the multiplicity parties involved and their effect in this delay, regardless to the type and nature of the construction project. The problem of delay is very large in Iraq because there are many different circumstances which have had negative effects on the economic situation of the country and on the deterioration of the services level required in time. The research sought to investigate the role of the parties involved in the implementation of the project to determine their responsibility in delaying the completion of the construction projects in Iraq and to know the roles and proportion of their responsibilities depending on the type and nature of the work provided by them in the implementation of the project through setting their priorities by using network analysis technique The final results show that the contractor, consultant and owner play an important role in the delay of the project with priority (38.52 %), (36.41 %) and (16.36 %) respectively. there are additional factors share with them in causing delay with priority equal to (8.71 %).
