摘      要：The development of elevated railway infrastructures in Indonesia is going rapidly. The uniqueness of the T-Pier construction in the elevated railway project is the construction method that causes many activities to execute. The explained activities in the construction method were not clear, neither treated in much detail. In line with the problem, this research aim is to identify T-Piers construction work activities specifically. The project sample was MRT Jakarta CP 103 elevated section and T-Pier construction was the object of the case study. The first stage of this research was archive analysis, expert validation, and surveying of 100 bridge engineers. The collected data were analyzed by the descriptive analysis method. Then the work breakdown structure tree diagram was developed and shown the activities development. There were 31 activities identified starting from preparation until finishing and grouped into the main section group of activities i.e. pile cap, pier column, installation, and dismantling of temporary shoring, and pier head group activities. All the experts agreed that the activities identified were valid and almost all respondents 100% agree. The activities identified were at level 5 in the work breakdown structure development. The detailed activities can be standardized as a reference in future similar projects.
