Abstract

Systematic project management is needed to ensure the project implementation time is in accordance with the contract or even faster, so the cost incurred can provide benefits and also avoid the existence of fines due to delays in project completion. This study discusses the acceleration of time and cost project in the implementation of high rise building construction projects using the Time Cost Trade Off method. The author will analyze the scenario of accelerating the completion of the project by comparing the addition of working hours by 4 hours (scenario 1) and additional labor (scenario 2). The results of the analysis found the estimated time to accelerate the implementation of the project is from the normal duration of 600 calendar days, after a crash duration there is an acceleration of time to 582 calendar days. With a time efficiency of 18 days / 3.00%. The total cost due to acceleration of time (including indirect cost) for the addition of overtime hours for 4 hours (scenario 1) obtained a normal cost of IDR 66,637,746,719 (excl. VAT), then after the crash cost there is an increase in the cost to IDR 70,224,661,008 (excl. VAT) with an over cost of IDR 3,586,914,289 / 5.38%. Whereas with the addition of labor (scenario 2) a normal cost of IDR 66,637,746,719 (excl. VAT), then after the crash cost there is an increase in the cost to IDR 71,454,128,134 (excl. VAT) with an over cost of IDR 4,816,381,415 / 7.23%.

Abstract

Construction projects often suffer from poor performance in terms of execution time management. This is a problem that must be taken seriously. When a delay occurs in a project, there will be additional costs that must be incurred outside the contract and can cause losses for the parties involved, especially the construction contractor. Therefore, it is necessary to pay more attention to the delay in implementation time. The research method used in this research is descriptive quantitative by determining the research variables based on previous journals. Supported by the distribution of phase 1 questionnaires and phase 2 questionnaires which were distributed to 40 respondents related to the Facility Workshop development project located in Melak, East Kalimantan. The questionnaire analysis was assisted by the SPSS version 25 program. The analyzes used were Validity Test, Reality Test, Descriptive Statistical Analysis, Normality Test, Multiple Regression Test, T Test and F Test. From this study, the factors causing delays based on descriptive statistical analysis that meet the requirements of the T-test are material factors (X1), with the indicator "Incorrect material delivery schedule (X1.2)" then supported by the results of multiple linear regression analysis with coefficient positive regression, meaning that there is a significant effect between variables and project delays.
