Formwork is a molding tool to get the shape of concrete to work as planned. The cost of making formwork is proportional to the cost of reinforced concrete work, so the right methods and strategies are needed to calculate the cost of formwork that can be used repeatedly. When making a bill of quantities, the cost of formwork used is adjusted to the work item, and in the calculation, the formwork that has been used in one application is no longer used for the next. But the reality in the field formwork can be used repeatedly with the right methods and strategies so that the cost for making formwork can be efficient by applying green construction strategy with the Reuse concept. This study aims to determine the methods and strategies as well as the percentage of green construction using green formwork for each building floor. The research method used is qualitative and quantitative methods. Qualitative methods are used to collect data through observation, interviews, and documentation related to the use of formwork in projects. Quantitative methods are used to calculate the cost of formwork for semi-system methods and one-floor rotation strategies. The results of the research found are the semi-system method and one-floor rotation strategy resulting in the formwork cost savings by 36.10%, and the reduced material on the application of green construction can reduce material successively by 8% for the second use, 16% for the third use, and 24% for the fourth use. This finding contributes to the list of work analysis related to formwork making.
