文摘

Since the mega construction project, typically defined as a contract that exceed $1 billion, requires a large scale financial investment, there exists a high possibility of having a budget constraint and limitation during the project execution stage as well as the planning stage. The previous studies were limited to analyzing the resource-constrained scheduling problems in the case of a budget constraint during the initial stage with smaller-scale projects and have never presented comprehensive approaches for rescheduling during the implementation stage and calculating its overall cost impact, especially on mega projects. As such, this study aimed to examine the methodologies and limitations of the previous studies and to analyze solutions to solve their shortcomings, thereby presenting a better methodology to practically apply to mega projects. Specifically, this study assessed the heuristic method that is the most applicable to mega projects and applied it to a real mega project, thereby suggesting a new method of construction process adjustment. The suggested method is expected to be appropriately used as a solution to similar issues with no restrictions to the size of the project.
