In the context of construction management, Social Infrastructure Projects (SIPs) have long been overlooked. However, SIPs are one of the main criteria for enhancing economic productivity. This paper analyses the results of a survey aiming to develop a framework for SIP success factors to enhance the likelihood of success in the provision of SIPs in Malaysia. The principal component analysis reduces a set of 41 project success factors to six dimensions based on the idea of the project life cycle, i.e., the preconstruction factor, the construction factor and post-construction factor, and three internal factors: the organizational factor, the information management factor, and the change management factor. Understanding these success factors could be crucial in managing SIPs, since it will allow project stakeholders to take precautionary steps to identify foreseeable problems and areas for improvement. This will increase the success rate of the project and could even help avoid problems completely.
