Abstract

The construction industry in Indonesia continues to grow, yet projects often face deviations from initial plans, particularly concerning cost overruns and schedule delays. This study evaluates the cost and schedule performance of the Revitalization of Pasar Gembrong Sukasari Market using Earned Value Analysis (EVA), a quantitative method for monitoring project efficiency. Data were derived from weekly progress reports, S-curve projections, and the project’s budget plan (RAB). At week 35, the Planned Value (BCWS) was IDR 55,052,769,527.00, while the Earned Value (BCWP) and Actual Cost (ACWP) both amounted to IDR 49,830,463,809.67. The Cost Variance (CV) of IDR 0 and Cost Performance Index (CPI) of 1.00 indicated precise adherence to the budget. However, a Schedule Variance (SV) of -IDR 5,222,305,717.33 and a Schedule Performance Index (SPI) of 0.905 revealed significant schedule delays. These findings demonstrate that while the project maintained financial efficiency, critical time management inefficiencies led to schedule overruns. The study underscores the effectiveness of EVA in identifying performance gaps and highlights the need for improved scheduling strategies to align time and cost objectives in construction management.

Abstract

Construction projects are bound by predefined schedules and budgets established from the outset. This study aims to optimize time and cost through a 3-hour daily overtime intervention, focusing on evaluating schedule acceleration effectiveness and resource efficiency. The Time Cost Trade Off (TCTO) method was applied via crashing techniques, systematically calculating cost-time trade-offs. Analysis centered on critical paths identified using the Critical Path Method (CPM), with schedule compression achieved through additional work hours. The findings reveal that the project duration was reduced from 180 days to 145 days, achieving a 35-day reduction (19.4%). This outcome demonstrates that targeted overtime interventions on critical activities optimize time allocation without compromising cost control, while affirming the relevance of the TCTO-CPM integrated approach in construction project management. overtime wages.

Abstract

The PPLP Banten Building construction project experienced significant delays due to the extension of the implementation time, design revisions (shop drawings), and inaccurate material delivery. This study implemented a schedule compression strategy using Microsoft Project with two acceleration alternatives based on the AHSP standard. The crashing research method. The results of the study showed that the project duration was successfully shortened by 678 days with the 4-hour/day overtime alternative, while further work shift optimization reduced the duration to 530 days. Cost analysis showed differences between the two alternatives: with 4-hour/day overtime, the acceleration cost reached IDR3,066,675,000 (AHSP), while the work shift only cost IDR1,223,565,000 (AHSP). Comparison of cost slopes strengthened the advantages of work shifts: 4-hour/day overtime resulted in a cost slope of IDR193,067,245.23/day (AHSP), while the work shift only cost IDR33,638,199.58/day (AHSP). Evaluation of total costs (direct and indirect) also confirmed the efficiency of work shifts, with direct costs of Rp9,512,731,986.58 and indirect costs of Rp1,273,456,116.78, compared to 4 hours/day of overtime which required direct costs of Rp9,672,161,032.20 and indirect costs of Rp1,322,728,805.77.
