Analisis Perbandingan Biaya dan Waktu Pelaksanaan Pondasi Spun Pile dengan Bore Pile pada Proyek Masjid Agung

Abstract

This study intends to compare the costs and time needed to carry out the work of the spun pile foundation with bore pile foundation. With the aim of knowing whether the planned costs and implementation time have the same efficiency or not. This study discusses the comparison of spun pile and bore pile foundations in sections 11, 12, 13 with the assumption that the load received from one spun pile group and one bore pile group receives the same load, for the cost analysis and execution time the author will analyze at 6 locations. The role of the foundation in building the initial structure of the building is very important. The selection of the appropriate type of foundation will expedite the process of building work, so that good planning is needed, including costs and implementation time. The foundation that is used as an alternative is the deep foundation, the spun pile foundation and bore pile foundation. This study analyzed for 1 pile cap, there were 4 piles in 6 different locations. This study concludes that based on the analysis of the cost and time of implementation of the spun pile foundation and the bore pile foundation that was examined, the results of the time analysis for the spun pile foundation needed 16 days and a 48-day bore pile foundation. Based on the cost analysis, the spun pile foundation requires a budget of Rp. 275,198,220.00 while the bore pile foundation is Rp. 489,887,437.00. Cost and time analysis of the implementation of the most appropriate foundation and can be applied in the work of the Great Mosque building is the foundation of spun pile, because the processing time is relatively faster and cheaper. Whereas the use of bore pile foundation is needed because the location of foundation foundation is narrowed with the location of other buildings, then another alternative is the bore pile foundation.
