Analisis Tingkat Keekonomisan terhadap Penggunaan Profil Kastela sebagai Balok pada Konstruksi Baja (Studi Kasus : Proyek Pembangunan Showroom Bmw Medan)

Abstract

Steel is one of the most-often-used materials in construction due to its various advantages, however a solution is needed to anticipate its price which is relatively expensive, i.e. by applying economical design in steel construction. One economical design that is quite popular today is the design of steel profile with openings on its web post or also called as castellated profile. In this study, the author analyzes the level of cost-effectiveness in the usage of castellated profile as the beam in Construction Project of BMW Showroom in Medan, with using value engineering techniques. The castellated profile is compared to the solid profile, which is the profile with a design that is commonly used in steel constructions. The comparison is conducted on the cost and the work management to determine which profil design is more cost-effective, and how much is the cost-effectiveness. After the analysis of value engineering is conducted, there is a saving of 17.509 % in the usage of castellated profile as the beam in Construction Project of BMW Showroom in Medan, if compared with the usage of solid profile. This is caused by the amount of steel material saving when using castellated profile which is equal to 15.519 % by weight and 56.466% by area. Through this study, the castellated profile results to be more cost-effective if compared to solid profile.
