Integrated Infrastructure Investment Project Management System Development for Mega Projects Case Study of Türkiye

Making investment decisions for infrastructure projects, monitoring and controlling investments is one of the critical issues that policy makers need decision support. Successful integrated project management is needed to evaluate the projects structurally and economically from a holistic perspective. It is necessary to design a framework to manage factors such as financing, technical capacity, contract management, equipment planning, known as limited resources in infrastructure projects. A roadmap guide is needed to manage these projects with limited resources. The use of digital systems in this regard provides an important advantage. Especially in public administration, monitoring the planned, ongoing, and completed projects on a portal with digitalisation opportunities are possible. GIS- based UYS developed by The Ministry of Transport and Infrastructure for digital monitoring of infrastructure projects is described in this article. Within the scope of system engineering, the UYS system has modules such as contract, performance, and planning. Program and cost performance indices can be calculated using the UYS methodology. Thanks to the UYS system, it’s possible to keep track of the goals set for contract management and constantly monitor the most critical tasks. The developed data health approach provides to the monitoring of the current data condition on the UYS platform. In addition, other projects related to the mega-project that followed can be monitored via UYS with integrated management. Approaches to the development of these modules are discussed in this paper. With the concept of earned value, the planned projection and actual follow-up for the projects are carried out, and activities with an increased risk level can be closely followed. It is also explained as a case study through the work of “Ankara-Sivas HSR Project”, a mega-project in which the earned value approach of the UYS system is followed.
