PENGENDALIAN WASTE MATERIAL BESI PADA PEKERJAAN STRUKTUR MENGGUNAKAN METODE BAR BENDING SCHEDULE (STUDI KASUS: PEMBANGUNAN PROYEK ICON BALI MALL, DENPASAR)

Abstract

In the implementation of construction project construction, there is reinforcing iron material. Reinforcement iron has a fairly high value so this material must be calculated and rearranged very carefully in order to get the optimal iron value. This study aims to find out the need for reinforcing iron, the percentage of remaining reinforcing iron materials, the cost comparison of reinforcing iron needs and the cost budget plan. The research methods used are descriptive methods and analytical approaches. The data analysis stage is carried out to calculate the need for reinforcing iron and the remaining (waste) of rebar using the Bar Bending Schedule method. From the results of the data analysis, the calculation of the need for reinforcing iron was obtained, namely D10 as many as 50,858 bars, D13 as many as 23,797 bars, D16 as many as 4,385 bars, D19 as many as 2,105 bars, D22 as many as 31,447 bars, S13 as many as 2,336 bars, S16 as many as 7,190 bars, S19 as many as 4,118 bars, S22 as many as 124 bars, S15 as many as 117 bars, and the average waste produced reached 5%. The cost of the total need for reinforcing iron is Rp. 22,839,464,959.54. The result of the iron cost requirement using the Bar Bending Schedule is smaller than the result in the Cost Budget Plan with a difference of Rp. 1,067,703,920.62 resulting in a savings of 4.68%.
