METODE PELAKSANAAN KONSTRUKSI KUDA-KUDA BAJA PROFIL PADA PEMBANGUNAN GEREJA GBKP DESA BUKIT KABUPATEN KARO

Abstract

A steel truss construction is a structure of trusses that supports the roof load, including its own weight. A roof truss system uses profile-shaped elements (I, H, C or U-shaped) to support and distribute the roof load to columns and foundation. In project of installing steel trusses for the GBKP Bukit church profile, using steel profiles is the right choice because the span of the building is 21 meters long and 21 meters wide. The purpose of this study is to determine the stages of manual work implementation of steel truss construction for the GBKP Bukit church profile, to determine the comparison of work duration and manual implementation costs with work using a mobile crane, to determine the budget plan (RAB) for the construction of steel trusses for the GBKP Bukit church profile. The installation method (using scaffolding and pulley assemblies). The method used in this study is a quantitative method by conducting observations during the construction of the steel profile trusses, collecting information in the form of interviews with contractors and head craftsmen and calculating the cost budget for the construction of the steel profile trusses of the GBKP Bukit church. Based on the research objective above, it can be concluded that the sequence of implementation stages starts from the planning stage, provision delivery, stacking, transport installation, fabrication of profile steel trusses and installation stage. The difference between manual installation and installation using a mobile crane are the manual installation method is Rp. 238,925,717,14 while the installation work using a mobile crane is Rp. 243,328,794.39. The total budget for the construction of the GBKP Bukit church profile steel truss based on the 2016 PUPR analysis is Rp. 238,925,717.14.
