Project risk issues have seldom been addressed from the perspective of jobsite engineers. This study presents a novel approach for collecting risk management data in order to understand the realities of risk management in Taiwan. In this study, accumulation contributing ratio of risk and distance of controllability are utilized as the two proposed criteria to extract the consensus critical risks of practitioners. The data are analyzed from multiple points of view to explore the co-relationship among risk cause, risk strategy, risk result and project stage, and to clarify the risk mechanism and the realities of risk management. This analysis found that the risk is highest in the structure construction and finish work stages, and that schedule postpones and negotiation risk strategies are widely adopted by project managers in Taiwan for all risk results. Conclusions also included that contractors worries about the risk causes concerning natural phenomenon, and contract-related issues at the pre-construction stage which lead to schedule delay and cost overrun risk results.
