Analysis of Minimizing Iron Material Waste for Construction Work in Wetlands with Bar Bending Schedule Method

The components of the material structure that are important in calculating requirements are iron requirements because iron requirements have a high value in construction work. Iron requirements such as reinforcing columns, beams, pile caps, sloofs, and others are widely used for reinforcement. The research aims to determine the need for stirrup reinforcement using a method based on field data with the Bar Bending Schedule (BBS) approach. The BBS method minimises the waste of material so that it only leaves the material in the screw-type iron reinforcement, around 14.79% for iron reinforcement with a diameter of 10 mm and 6.65% for iron reinforcement with a diameter of 16 mm. As well as for plain iron reinforcement, only leave material around 0.01% on mm diameter iron reinforcement. The bar bending schedule method can optimize the remaining material from the remaining length of the iron by reusing it for other iron piece plans where the piece’s dimensions can meet the previous rest.
