Abstract
Infrastructure is one of the important elements in the development of a country. The number of bridge infrastructure projects that can increase the growth of the construction industry in Indonesia must be supported by construction technology as well as the use of precast box girders. Problems arise due to inaccurate planning and production scheduling of box girder which causes the project delay. For this reason, it is necessary to carry out an analysis of the measurement of the box girder production cycle time as soon as possible so that it can provide an overview and reference in planning and scheduling elevated infrastructure projects. The purpose of this research is to measure the box girder production cycle times in Indonesian infrastructure projects. The main variable is the box girder production cycle time. The projects observed were projects in the last 3 years from 2016 to 2020. And the segment production chosen were segments with straight alignment. Average analysis is used to know the average of cycle times. Based on the results of the analysis, the average production cycle time is 38.95 hours with an average delay time of 6.28 hours. The average production cycle time can be used as a reference for planning and developing schedules for elevated infrastructure projects.
