Abstract

On Samarinda-Anggana Road Improvement Project, in estimating the time and cost of a project, an acceleration process is needed. Acceleration is usually done to optimize the duration of existing activities and to minimize risk but it still gets optimal results. One of the ways to achieve time and cost efficiency is by using the method of with modification of CPM model scheduling on the activities of the critical path. The objectives of this research are: 1) Determining the optimal result with the Fast Track process on the project, 2) Determining the cost plan for the time acceleration, 3) Calculating the amount of time difference of optimum acceleration in the completion of road improvement project and cost caused by acceleration. This research uses fast track method. From the calculation of the project duration using fast track method, the following results are obtained: 1) road improvement project of Samarinda - Anggana calculated with the CPM model with normal duration in the contract time is 210 days, so the project needs to be accelerated by Fast Track method that produces acceleration duration to 171 days, 2) the optimum cost incurred in the normal duration or the project budget plan is Rp.16.677.156.783,43 and costs gained after Fast Track method is Rp. 16.522.297.470,44, 3) the difference in duration between normal time and after fast track is 39 days. While, the difference in cost between normal time and after using Fast Track is Rp.154.859.312,99, it can be concluded that it saves 0.93% from the normal cost.

Highlights

As the development of the industrial world goes by as well as the development of transportation facilities, especially roads that are growing rapidly, the difficulty level to manage and run a road project is much higher
This study analyzes the acceleration duration for Samarinda-Anggana Road Improvement Projects along 1.95 km, and costs incurred by acceleration using CPM (Critical Path Method) Fast Track
The total project completion according to the contract for 210 calendar days which its work starts from 20 July 2016 - 08 December 2016 with total project cost is Rp.18.344.872.000,00 including Value Added Tax (VAT)

Summary

Introduction

As the development of the industrial world goes by as well as the development of transportation facilities, especially roads that are growing rapidly, the difficulty level to manage and run a road project is much higher. With good time management and execution, the risk of a road construction project will have a little retardation. This will directly reduce the project cost of the project, and it will provide its own advantages for contractors as responsible for project implementation. In which in planning time scheduling activities, specific procedures have been provided to complete construction activities more quickly and efficiently. The success or failure of the implementation is often caused by lack of project plan activities and less effective controls, resulting in inefficient project activities, resulting in retardation, declining quality of work, and increasing implementation costs. This need fluctuation will affect the budget because there is a moment when resources are not empowered while the costs remain out, in which it is called fixed cost
