An economic evaluation model for concession on convention infrastructure projects in Greece

Scientific management of projects constitutes an area of expertise in the field of engineering that requires a combination of various skills from different scientific sectors in order for it to get efficient and complete. The need for construction of numerous and large scale transport infrastructure projects in later years led the engineering sector, and primarily major construction corporations, as well as the public sector to carry out viability and evaluation studies for all major transportation infrastructure investment. This need was amplified when numerous infrastructure projects previously funded exclusively by the public sector and European Union’s grants started to get funded by the private sector and constructed with the concession-on-convention method. The present essay intends to develop a mathematical model for retrieving the economic and technical parameters that are involved in such a concession-on-convention project and especially for the examination of its viability and its return-on-equity.
