The Method of Modified Fast-track for the Acceleration of the Highways Construction Project Schedule

The implementation of road projects schedule in Indonesia tends to be slow, this influences the construction cost to rise. The method of fast-track acceleration is often applied in solving such problem, yet, many studies stated that fast-track cannot fully restore the prolonged schedule. On another side, the fast-track acceleration requires additional costs. This article explains the ways acceleration of the implementation period can alter the relationship among the activities on critical path, known as modified fast-track, and the case is the highways construction projects. The CPM method is applied for scheduling and the EVM is applied for cost, the data are processed non-statistically. The finding obtained is that fast-track has an acceleration effectiveness of 9%-12.56%, while modified fast-track is at 16.30%-22.26%. Fast-track can reduce the actual cost up to 6.75%, while on the other hand, modified fast-track can do it better up to 10.55% and is able to project a profit up to 9.56%. Modified fast-track can be considered more effective in accelerating the schedule and more optimized in cost.
