Column formwork works is one important part of construction work on the building. And construction industry is one industry that is dynamic and always evolving, especially in technology infrastructure. Much development formwork works implementation method that has been done to improve productivity, and one of which is prefabricated formwork. Prefabricated formwork has been a component of a temporary structure that is essential for high rise building projects. And in the end, the purpose of this research is to improve the productivity of the column formwork works in the construction of prefabricated buildings using time-motion method studies.Column formwork works is limited only to the column formwork installation work, and process data using the method of flow charts, process charts, crew balance chart, and the cycle chart. Method of time-motion studies is direct observation at high rise building project, Grand Royal Panghegar Apartments, Bandung, West Java Province, Indonesia. Data is collected by recording and using recording devices such as camcorders or stopwatch, and display boards. The results of these observations is the production cycle time with data every task, every person who works, as well as the position and location of existing resources in each work process. Method of flow charts, process charts, crew balance chart, and the cycle chart using the cycle time data observation and compare it with the proposed cycle time of each method. The cycle time of the first proposal of the method to be used in subsequent method thus getting maximum productivity gains in the last method. Increased productivity is the result of the proposed work best for prefabricated formwork on the ground in a way to streamline the work of several sides. The results are displayed in the form of tables, figures and graphs. <br /> <br /> <br /> <br /> <br /> There are several factors that affect productivity value of column prefabricated formwork works. These factors are the variation distance transportation of formwork, the limitations of equipment, work space, storage space tool, as well as labor management and overall project implementation method.
