Hence, implementation of sustainable factors is essential. This paper attempts (1) to review infrastructure project sustainability factor and performance, and (2) to propose a framework of relationship between the sustainability factors and performance for railway projects in Malaysia. The results from the literature show that sustainability factors and performance can be categorized under environment, economic, social, engineering/resource utilization and project management.
