Lessons Learned, Barriers, and Improvement Factors for Mega Building Construction Projects in Developing Countries: Review Study

Abstract

A mega-project is a major project or a group of projects of significant cost that attract a high level of public attention or political interest because of substantial direct and indirect impacts on the community, environment, and state budget. Capturing and sharing the knowledge from the performance of the current mega projects is essential in order to avoid losing vital corporate knowledge assets in the construction industry. The learned lessons are gained from experience, success, and failure for improving future performance. This research aims to review and read out the lessons learned from 77 research papers that have dealt with the barriers that hinder the successful performance of mega building construction projects in developing countries, identify and classify the main obstacles, and propose improvements for successful implementation and management of mega building construction projects. The results of this paper will help project owners, construction companies, and other stakeholders in developing countries to overcome the limitations in the execution of mega building construction projects.
