Abstract :
A very effective and strategic factor in the success of transportation projects is the process of selecting an execution system (delivery option). This is the reason why identifying the challenges and selecting an appropriate execution system in transportation projects are quite important; proper selecting will lead to proper progress in the execution of the projects of this sector which is somehow the basis for the country’s development. In this paper, using extensive field studies, the most important affecting factors of the existing main execution systems in Iran, including Design-Bid-Build (DBB), Design-Build (DB) and Construction Management (CM), in road, railway, and freeway projects were determined. Then, using the Analytic Hierarchy Process (AHP) and the Expert Choice software, the appropriate execution system for each of such projects were identified and grouped.
