ANALISIS PERCEPATAN WAKTU PENYELESAIAN PROYEK DENGAN METODE CRASHING DAN FAST TRACKING PADA PELEBARAN JALAN DAN JEMBATAN

Abstract

To obtain a better profit without ignoring work safety and quality of work, the acceleration of
the implementation of the work of a construction project can be done using the Crashing and
Fast Track method. The research objective is to determine the amount of cost and time
incurred by the acceleration of implementation and determine the magnitude of the difference
in budget and time spent with the Crashing and Fast Track methods. The Crashing method
uses 2 types of variables, namely the addition of 1 hour, 2 hours and 3 hours overtime, and
the addition of heavy equipment and labor, while the Fast Track method uses 3 times the
overlapping application of work items. It turns out that the most optimal result is the addition
of 2 hours of overtime work for 163 days so there is a reduction in costs of Rp. 156,358,936,
while the Fast Track Method obtained the most efficient results are the results of operations
with a total duration of 130 calendar days, and with a total cost of Rp. 16,812,941,734,38,
while the difference between the total plan and the cost after Fast Track is: Rp.
340,933,265.63. The Fast Track method is cheaper than the Crashing method which uses
overtime hours for 2 hours.

Keywords: acceleration of project time and cost, Crashing method, Fast Track method.
