Abstract


In the construction project activities there are three things that influence the success and failure factors of time, cost and quality. The success of a project is usually seen from a relatively short turnaround time without neglecting the quality of the project work. Proper and regular project management is needed to ensure project time, cost and quality. This is to avoid undesirable things like late delays, cost swings, quality failures, and so on that could have an impact on project failures and the cost of fines. The purpose of this study is to calculate changes in project cost and time of the project with an alternative to adding overtime hours comparing the results between normal and cost changes after the addition of working hours (overtime). The data used in this research is secondary data obtained from contractor implementing. Data analysis using Microsoft Project 2007 program and time cost trade off (TCTO) method. The result of the analysis is the critical path and the increase of the cost due to the addition of working hours (overtime) while the result of time cost trade off method is the acceleration of duration and the increase of cost due to acceleration of duration in each accelerated activity. The results of this study indicate that the total project time and cost under normal conditions is 117 days at a cost of Rp 8.000.080.361.56 with the addition of 3 hours of overtime work in the duration of crashing 98 days and at a cost of Rp 8,147,282,633.64, in addition to 5 hours of overtime work obtained duration crashing 95 days and cost of Rp 8,157,344,186,22.
