Modeling of Client - Contractor communications for successful execution of Mega rojects in Downstream Oil Industries

This study has been followed with the aim of communications model validity evaluation, between Clients and Contractors in mega projects in the field of Oil Industries. Such model explains the relationship between factors via measuring the respondents` perceptions. The respondents have been chosen from Contractor/Consultant and Client firms. The impressive factors have been extracted from the literature review of the research and Delphi method which has been done formerly. The result were interpreted and analyzed by the Exploratory- Conformity Factor analysis and finally Structural Equation Modeling. Based on factors loading scores and components loading distribution, the relevant clusters for each five latent factors were extracted and named. The presented model explores the relationships between sensational factors through communications between Client and Contractors of Oil downstream projects. Also such model quantifies the influences of each factor on the others. The outcome of this study will be useful for promotion of client's and contractor's staff in order that recognizes and mange those factors in different stages of the projects.
