Comparison Analysis for Implementation Time of Column Formwork Using Three Formwork Methods in a Building Project at Bandung Province

The construction world, especially in modern times, technological innovations are developing rapidly. One of these innovations is formwork. The real proof of its development is the formwork method, which has an increasing number of types. This study describes the time comparison between the three formwork methods consisting of conventional, semi-system, and full system formwork for column work on the UPI Bandung multi-storey building project. The research method that has been done is quantitative. The analysis is carried out by calculating the volume of work, identifying the coefficient of workers from journals and articles, calculating labour productivity and then the duration of work for each formwork method can be calculated. The results obtained from this study regards the duration of work on each formwork method column in each building studied. In conclusion, the duration of column work with the conventional formwork method has the longest duration of work, followed by the semi system method and the full system method.
