Abstract

Road infrastructure is essential for supporting transportation, fostering economic growth, and enhancing community mobility. However, the Bungur-Kedoyo road construction project in Tulungagung has faced challenges in time and cost management, impacting overall project performance. This study aims to evaluate the project's time and cost performance using the Earned Value Method (EVM), a robust tool that compares planned work, completed work, and actual costs to provide a comprehensive performance analysis. Data from the 25th-week project report revealed delays, with a Schedule Variance (SV) of -Rp. 315,481,514.90 and a Schedule Performance Index (SPI) of 0.970, indicating slower progress than initially planned (SPI < 1). These results highlight the need for improved project scheduling and enhanced control mechanisms to mitigate delays and manage costs effectively. By identifying inefficiencies and areas requiring intervention, the study provides actionable recommendations for improving project management practices. It concludes that integrating EVM into time and cost control processes can significantly enhance project efficiency and reliability.

Abstract

The construction of the Probolinggo-Banyuwangi Toll Road Package 2 is a strategic project that plays a critical role in enhancing infrastructure connectivity in East Java. However, it faces significant risks arising from both internal and external factors. Internal challenges include limited availability of skilled manpower, inadequate heavy equipment, and poor project coordination, which hinder project efficiency. External challenges, such as fluctuating raw material prices, regulatory changes, and adverse weather conditions, further complicate the implementation of the project. These risks, if unmanaged, could result in delays, cost overruns, and compromised project quality. This study focuses on identifying key risk factors and developing effective mitigation strategies through qualitative and quantitative risk analysis. Priority risks, including material delivery delays, frequent design changes, and financial instability, were identified as critical to the project’s success. The findings underline the importance of proactive and structured risk management approaches, as guided by frameworks like ISO 31000 and AS/NZS 4360, which emphasize early risk identification, assessment, and mitigation during the planning phase. Furthermore, the research highlights the necessity of strong coordination among stakeholders, from government agencies to contractors and subcontractors, to mitigate risks collaboratively. Developing a risk-conscious organizational culture is crucial to ensuring project efficiency, not only in terms of cost but also in time and quality management. By implementing a systematic and integrated risk management framework, the Probolinggo-Banyuwangi Toll Road Package 2 project can serve as a model for managing risks effectively in large-scale construction projects.

Abstract

This study aims to analyze the impact of elevator installation delays on the schedule and budget of a 10-story office building construction project in Gresik. By comparing two scenarios—on-time elevator work versus delayed elevator work—this research uses a comparative analysis approach based on project documentation, interviews with stakeholders, and cost and time data. The findings reveal that delays in elevator work significantly affected the overall project timeline, causing a shift in the schedule and necessitating changes in structural methods, particularly the use of steel instead of concrete for the separator beams. This change expedited construction but increased costs substantially. The study also highlights the cascading effects of these delays, which led to further adjustments in the building's structure and increased labor and material costs. The research emphasizes the importance of early-stage planning, coordination, and the adoption of advanced project management techniques, such as Building Information Modeling (BIM), to minimize risks and ensure timely project completion. In conclusion, the study provides valuable insights into how elevator delays can disrupt construction projects and recommends strategies to mitigate such risks in future developments.
