Supervision Indicator of Formwork on Reinforced Concrete

This research aims to investigate formwork supervision that will be used as a model of reinforced concrete supervision. The research was conducted in Medan by using the survey method. The research sample consist of 20 construction projects which were under construction in Medan in 2016 with the purposive random sampling method. A research instrument was used as a guidance for supervisors, the interview was developed by researchers. Data obtained was analyzed by using descriptive analysis. The result of the study is that there are five categories of supervision indicator which may impact the quality of formwork, they are: 1) precision e.g: elevation, dimension and distance, perpendicular, flatness and elbow of building shaft, 2) stabilizing and stiffness of formwork, 3) leakage indicated by sealed connection, casting disconnection, neatness of pipe sparing 4) formwork material indicated by wood quality and smooth potted surfaces, 5) work verification indicated by installation date, usage date, work volume, signature and supervisor's name approved by quality control.
