Abstract

Cost, quality and time are important aspects planned in the implementation of construction. Achieving optimum quality at a lower cost is the main goal desired in project implementation. This study aims to determine the comparison of project costs with the application of the Crashing method on the Lamongan District building construction project. The normal cost required to carry out the construction is Rp. 1,144,445,838.00 with a project duration of 150 working days. The crashing method is applied by adding additional working hours (overtime). The duration of working hours is increased to 3 hours, so it is expected that with this addition, the volume of work produced is greater. The results of the study obtained that the total cost after being accelerated with the addition of work duration was Rp. 1,162,252,577.00 or more expensive 1.55% of the normal cost and the duration of the project implementation is 143 working days. With this addition, the project duration is faster by 7 days.

Abstract

In a construction project, there are several aspects that cause the project not to go according to plan. Cost and time are aspects that need to be considered to avoid losses incurred in a project. Jombang-ploso-legundi-gresik road project is one of the road widening projects carried out by PT. Mix Pro Indonesia. The project was carried out with the aim that access to (Surabaya-Mojokerto) or further trans Java toll road is quicker safe and smoother. This research aims to optimize the cost and time on the project using the Earned Value method. Calculations include the calculation of ACWP (Actual Cost of Work Performance), BCWS (Budgeted Cost Work Schedule), and BCWP (Budgeted Cost for Work Performed) using the Earned Value method. From these parameters, estimate aspects of cost and time. As well as project analysis of acceleration on a critical trajectory of work. The results of calculations in the 12th week obtained a BCWS value of Rp 1,216,677,846,400 BCWP = Rp 3,040,372,140,080, ACWP = Rp 3,678,560,000. CV value = -Rp 109,203,495.92, SV = Rp 895,646,816.82, CPI = 0.827, and for SPI = 2,499. From these results it can be seen that the CPI value < 1 which means that there are project expenditures that exceed the original plan. With the results, it can be used as a reference in the implementation of project activities.
