Abstract

The railway infrastructure development is being a concern to the government of Indonesia nowadays. One of construction methods mostly applied in building the railway infrastructure is box girder application with launching gantry. After observing several big projects with this method, some problems are identified. One of the problems is different work activities conducted during box girder erection. According to this situation, this research was conducted to identify precast box girder erection activities to develop work breakdown structure. The WBS will enhance the efficiency and effectivity of similar projects in the future. To conduct the analysis, there are three steps to be executed. They are archive analysis, expert judgement and surveys. For archive analysis, two big projects are observed and compared. Secondly, the judgements are obtained from five experts who have fulfilled more than ten years working experiences especially in public infrastructure construction. Thirdly, the direct surveys were held to thirty elected respondents regarding this topic. Finally, the descriptive analysis was applied to draw the result. This research conveys the WBS which has been developed according to aforementioned analysis method. There are 13 identified activities. They are preparation, box girder transportation, box girder lifting, position setting, epoxy gluing, temporary PT bar stressing, alignment surveying, PC stand and accessories installment, permanent stressing, patching, grouting and bearing installation re-surveying. This WBS is necessary to be used as a reference standard for future similar projects.
