ANALISIS PERBANDINGAN WAKTU DAN BIAYA PELAKSANAAN PEKERJAAN STRUKTUR BALOK PRECAST DAN BALOK KONVENSIONAL PADA PROYEK PEMBANGUNAN GEDUNG KANTOR (DPMPTSP, DISNAKER, DISKES, DAN CAPIL) KABUPATEN GIANYAR

Abstract

Infrastructure development in Indonesia is currently growing rapidly. Construction projects are continuously evolving with the changing times. With technological advancements, more methods are being developed to facilitate construction implementation. In the ongoing execution of a project, choosing the right method can yield optimal results. In construction, there are two known methods for concrete work: the conventional method and the precast method. The aim of this research is to compare the time and cost of implementing conventional beams versus precast beams and determine which method is the most effective to use. This research employs a descriptive quantitative research design. The results of this study show a comparison of time and costs between conventional and precast beam work. The implementation time for precast beams is faster by 4.10 hours or 8.7% compared to conventional beams, and precast beams incur higher costs, amounting to Rp. 6,043,670.76 or 10.06% more than conventional beams. The most effective method to use is the precast method.
