Analisis Pemilihan Metode Cast in Situ Dan Precast Terhadap Biaya Pada Pekerjaan Tempat Duduk Tribun Stadion Utama Jakabaring Palembang

Cost efficiency has become a major problem in many construction projects, especially on large scale of concrete work. Concrete work can be divided in two types; which are cast-in-situ and precast. However, cost efficiency, by using such method, can be achieved if the concrete work meet these criteria; large scale volume, typically in form and repetitive work needed. This research is aimed to analyze concrete work using cast-in-situ and precast methods based on cost approach. The data of this research was taken from field study based on real condition of the project of the Jakabaring Sport Center Stadium, Palembang, which was focused on the concrete work of sport stadium benches. The research concludes as follows; the overall cost efficiency of the production of precast concrete of Jakabaring Sport Center Stadium, Palembang versus that of cast-in-situ is 18,29% (Rp. 840.217.466,19-). The efficient point achieved when the volume of production of precast concrete is 382,1m3 with cost of Rp. 1.021.630.000,- (27,21% of total cost of precast concrete production cost)
