The relationship between uncertainty factors and refurbishment project performance with leadership quality among project managers as a mediator / Ridzuan Yacob

The number of Building Refurbishment Project (BRP) has increased significantly over the past few years in Malaysia. In regard to this, it is important to note that the key features of these projects are unique which include Uncertainty Factor (UF) especially when these involve structural modifications with sensitive, dangerous and difficult operations as well as the high number of building services involved. A considerable amount of studies has identified UF as one of the reasons for poor performance of BRP which encompasses the aspects of time, cost, quality, and safety. This emphasis is questionable in the real world. A significant attention has been given to this topic in recent years, however, most previous research that provided solutions for the poor performance issues only focused on technical measures in the planning and design process without investigating human impact elements in construction process. Specifically, Leadership Quality of Project Manager (LQPM) was not examined. The aim of this research was to establish the mediating effect of LQPM between UF of construction process and the performance of BRP which encompassing time, cost, quality and safety.
