PERENCANAAN PONDASI TIANG BOR PADA BANGUNAN 12 LANTAI GEDUNG ATTIC SHOWROOM SURABAYA

Attic Showroom Building Surabaya is a 12-story building that stands in a densely populated area, with soil conditions at a clay-typed location. The purpose of this thesis is to plan the bored pile foundation on condition at the location by considering the carrying capacity of the pile and the consolidation reduction, which will later become a reference in planning the work implementation, calculating construction costs, and making scheduling. Calculation of loading refers to PPIUG 1983, while calculating and designing the foundation using Standard Penetration Test (SPT) data, as well as calculating cost estimates using the Surabaya City Base Unit Price 2020. From the calculation results obtained load loading of building structures amounting to 817,432 tons using LRFD combination . While from the results of calculation and foundation planning, the dimensions of the foundation pile foundation 1 m and foundation depth 20m with the carrying capacity of the press mast are 263,101 tons, and pile cap planning with dimensions of 5 x 5 x 1m with the number of piles in one pile cap is 4 pieces. The calculation of the budget plan for the cost of the foundations of the compressed pile is Rp 6.080.326.766,84. The method of implementation itself uses a bentonite. The duration obtained for this work is 35 days by scheduling using the MS Project application.
