Abstract

In the implementation of construction projects, reinforcing steel material is a component that greatly influences the cost of a project. Reinforcing steel material in the composition of concrete is a component that determines the cost of a project. In the implementation of construction projects in the field, the use of reinforcing steel material often results in quite large material waste which greatly affects the cost of the construction project, therefore it is necessary to try to minimize the remaining reinforcing steel material. To be able to reduce the remaining reinforcing steel material, it can be done by optimizing the need for reinforcing steel so that it can reduce the remaining pieces that can be formed. The purpose of this study was to calculate the need and percentage of waste of reinforcing steel in foundations, sloofs, columns and beams based on shop drawings in the North Kuta District Office Building Construction Project. The method used to optimize the need for reinforcing steel is the bar bending schedule method. From this study, the results of the need for D19 reinforcing steel were 1056 bars, D16 iron was 80 bars and ø10 iron was 643 bars. Then the remaining iron waste material produced is D19 iron of 6.35%, D16 iron of 0.45%, and ø10 iron of 4.83%.
