ANALISIS PERBANDINGAN WAKTU DAN BIAYA PELAKSANAAN PEKERJAAN BALOK BETON BERTULANG ANTARA METODE BETON KONVENSIONAL DAN PRECAST ( Studi Kasus Proyek Pembangunan Gedung Dekanat Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Udayana )

Abstract

Currently, the development of the world of construction is growing rapidly with the existence of various breakthrough methods in terms of planning and methods of carrying out work. With advances in technology, of course, more and more methods are created to facilitate the implementation of construction development. So that with these various methods, the choices for carrying out construction work are also increasingly diverse according to needs and still pay attention to the terms of time, quality or cost. In the world of construction, there are jobs that are considered very important, namely structural work, one of which is concrete structures. In general, there are 2 methods of concrete work used, namely the conventional method and the precast or precast method. The purpose of this study is to compare the cost and time of carrying out conventional beam work with precast beams. The results of this study are that precast beams are more expensive with an average difference of Rp. 87.730.569 or 23.18% of conventional beams and precast beams work faster with an average difference of 28.21% of conventional beams and differences in floors with the same type of beam do not have a large effect on costsand time.
