Urban transformation projects are discussed in terms of the level of realization of the aim targeted by the actors. Neglect of transparency in the project phases and insufficient participation of all actors give rise to problems that cause resistance of the actors, provoke social disturbances, and hinder implementation. To minimize these problems, this paper presents a method for objective evaluation of multiactor projects that encompasses questioning the achievement level of the initial project aims set by the project actors. For this process, this study used the analytic hierarchy process in two case studies, both in Istanbul, Turkey. As a result, the method and principle in this paper can provide a theoretical method to measure and supervise the multiactor project's success in a way that more consistently realizes the transparency and accordance of the actors. To ensure a 60% achievement rate among all actors, or at least ensure a healthy settlement structure and preserve and renew the historic and cultural sites and local architecture, taking measures against natural disaster risks and improving urban living standards should be realized in these case studies.
