Abstract: This study aimed to develop, and present a model to portray a mechanism on how institutional elements would impact on performance of construction megaprojects. To this end, 19 in-depth interviews were conducted with managers and senior engineers with more than 15 years of experience in megaprojects in the field of gas, oil, petrochemical plants, dams and urban tunnels. The data was analysed using the Glaserian approach of the grounded theory. The results showed how institutional elements created problems during the implementation of megaprojects, how megaproject actors reacted to these problems, and what the final impact of problems and reactions was on the performance of megaprojects.

Keywords: megaprojects; construction; institution; institutional impacts; institutional elements; performance.
