Innovative reliable approach for optimal selection for construction infrastructures projects delivery systems

Abstract

The major difference between infrastructure projects and conventional projects is in the high cost, great mass production of work, and the high level of technology. Any error, whether due to uncertainty or miscalculation in infrastructure projects, leads to great crisis that is hard to repair, so it is mandatory to pick the optimum infrastructure project delivery methods with great attention. Based on the historical definitions and comparisons for the different methods of project delivery, a new approach and sophisticated decision model was reached for choosing the optimal discipline to deliver the infrastructures projects. And that’s the main goal of this study that is to provide an upgraded model to help the decision-maker, for getting the perfect choice to deliver the infrastructure project. Many expert opinions have been gathered, (including a contractor, owner, and consultant) on the advantages and disadvantages of the most common project delivery systems, and four main methods have been reached to be studied. By establishing a final main list of the most important criteria that affect the choice of delivery method and the application of the Simos’ procedure, a novel methodology has been reached to make the best decision.
