Construction of Road, Bridge and public city transportation such as LRT (Light Rapid Transit) and MRT (Mass Rapid Transit) is part of the National Strategic Program and Priority Program. Most have the form of elevated construction (at a height with a certain level). The characteristics of elevated road construction are construct at a height level, construction work at congested area and have to fulfill acceleration target due to RPJMN 2015-2019. The construction requiring the selection of construction methods that need to be supported by the use of technology through the use of efficient structural materials such as pre-printed concrete, use heavy equipment, engineer and worker competency support, and management capabilities and capacities in planning, designing and implementing construction. Elevated road have high risks and potential challenges such as the risk of incidents and accidents. From August 2017 to March 2018 there have been 15 construction work accidents in a row and 11 of them occurred on elevated road projects. This condition triggered the decision of the ministers of PUPR, Transportation and BUMN to carry out a moratorium or dismissal of construction activities of 32 elevated toll road projects and 4 city transportation in Indonesia. In this study an effort will be made to identify the root causes and the mechanism of the occurrence of incidents and work accidents on elevated road construction projects. For this reason, it is necessary to do a number of steps, namely the initial step through statistical efforts to explore the development situation of work accidents so that a general description of the situation of development of workplace accidents in the Elevated road Infrastructure Construction Project. The next step is through reviewing how the Protective Barriers System of incident and accident in each of the existing elevated road infrastructure projects. The review is carried out more broadly in the stages of organizing Construction and the application of the K3 Construction Management System. The final step is to trace the root causes, mechanisms of occurrence and causal relationships between the root causes of elevated road infrastructure construction projects. The method of data collection is done by studying the literature on workplace accidents, the theory of causes of accidents and models of the mechanism of accidents. Then proceed with field surveys with questionnaire and interview instruments. The method of processing the root causes of incidents and work accidents uses the EUROSTAT model to trace the development situation of workplace accidents so that a general description of the situation of development of workplace accidents is obtained, followed by a descriptive analysis of the results of interviews and then the root causes and mechanisms of Fault Tree Analysis (FTA) on elevated road Infrastructure Construction Projects. The results show that the complexity and acceleration of projects support conditions and situations so that incidents and work accidents occur. Incidents and work accidents on elevated road infrastructure construction projects need to be widely reviewed from the start of the construction stage. There are 2 things that play an important role in the occurrence of work incidents and accidents in elevated road infrastructure projects, namely the quality of the protective barrier system in the form of implementing a good construction process and the application of Construction SMK3. The search results obtained 19 root causes and 26 combinations of minimum cut sets of causal relationships between the root causes that caused incidents and accidents
