Efisiensi Waktu Dan Biaya Dengan Metode Time Cost Trade Off (TCTO)

Studi Kasus: Pembangunan Proyek Apartement Gunawangsa Gresik Superblok

Abstract

During the implementation of construction projects there is often a discrepancy between the schedule of the plan and the implementation in the field. This also happened in the Construction of Gunawangsa Gresik Superblok Apartment Project, which was delayed due to the focus on building the mall resulting in the delay of the construction of Apartement Gunawangsa Gresik Superblok Therefore it is necessary optimization to know the efficiency of the time needed. To find out the efficiency in the Construction of Gunawangsa Gresik Superblock Apartement Project, the calculation is done using the Time Cost Trade Off (TCTO) method with 2 scenarios namely the addition of 2 hours of overtime and 3 hours of overtime work. The data needed to calculate acceleration using the Time Cost Trade Off (TCTO) method include: Cost budget plan, wage price, and s curve. On the original plan the project took 475 days to complete, The results of this study showed that the first scenario (the addition of 2 hours of overtime) gets a completion time of 396 days with the required acceleration cost of Rp. 3,335,592,782.75, while the second scenario (additional 3 hours of overtime) gets a completion time of 376 days with the required acceleration fee of Rp. 3,513,690,228.75. The most optimal scenario is the addition of 2 hours of overtime because it has less duration than the normal duration and less cost.
