Abstract

Pada Proyek Pemeliharaan Berkala Struktur Ruas Jalan Samaran-Banjar, Kecamatan Kedundung, Kabupaten Sampang masih belum diketahui penyimpangan dan keterlambatan yang terjadi. Agar tidak terjadi penyimpangan dari yang telah direncanakan maka selama pelaksanaan proyek perlu adanya pengendalian terkait biaya dan waktu. Maka dari itu perlu dilakukan analisis untuk mengevakuasi pengendalian biaya dan waktu dengan menggunakan metode Earned Value Analysis (EVA). Kinerja biaya proyek Pemeliharaan Berkala Struktur Ruas Jalan Samaran-Banjar, Kecamatan Kedundung, Kabupaten Sampang jika mengacu pada kegiatan pelaporan dapat dilihat dari minggu ke 1-8, nilai CPI <1 menunjukkan bahwa biaya yang dikeluarkan melebihi pekerjaan yang telah diselesaikan, Sedangkan minggu ke 9-10 nilai CPI >1 yang berarti banyak pekerjaan yang telah diselesaikan dibandingkan dengan pengeluaran. Kinerja waktu proyek Pemeliharaan Berkala Struktur Ruas Jalan Samaran-Banjar, Kecamatan Kedundung, Kabupaten Sampang nilai SPI >1 di minggu ke 1 yang berarti penyelesaian pekerjaan proyek lebih cepat dari jadwal yang direncanakan. Pada minggu ke 2-8 nilai SPI <1 dengan kata lain, lebih lambat dari yang direncanakan semula dan pada minggu ke 9-10 SPI =1 yang berarti proyek selesai tepat waktu.

Abstract

This study identifies and validates critical risk factors in storage tank construction projects through a Systematic Literature Review (SLR) and expert judgment using Aiken’s V method. Initially, 103 journal articles were screened, with 43 selected for in-depth analysis, revealing 33 causal factors and six key risk categories. A Focus Group Discussion (FGD) involving industry professionals (project managers, QA personnel, safety officers) enriched the findings by incorporating practical insights missing in academic literature. Eight experts then evaluated these factors using Aiken’s V, validating 13 causal factors and four risk factors as highly significant. Key causal factors included Structure Design, Material Delivery, and Foundation Design, while major risk factors were financial loss, non-compliance, workplace accidents, and poor-quality outcomes. The study establishes a structured risk model for storage tank projects, supporting future quantitative risk analysis and mitigation strategies.

Abstract

Rapid development in the construction sector is strongly influenced by its crucial and efficient functions. This drives the construction industry towards better integration. Currently, advances in technology and communication play an important role in overcoming various challenges, one of which is through the implementation of Building Information Modeling (BIM). This approach supports more integrated design and construction processes, resulting in higher efficiency. A primary challenge in construction service provision is the discrepancy in work volume, which can affect project success. By using Autodesk Revit 2025, the implementation of 5D BIM for material Quantity Take-Off can provide higher accuracy in volume estimation. In its implementation, data is processed using Autodesk Revit 2025 BIM software integrated with Microsoft Excel for further analysis. The results show that total volume calculations using Autodesk Revit are more precise compared to conventional methods. The volume of concrete work based on BIM is 2,005.35 m³, which is 83.31 m³ lower than the conventional method at 2,088.66 m³. Meanwhile, the reinforcement volume based on BIM is 354,670.98 kg, which is 29,024.91 kg lower than the conventional method at 383,695.89 kg. The contribution of this research is the demonstration that the implementation of 5D BIM using Autodesk Revit 2025 significantly improves the accuracy of structural work volume calculations compared to conventional methods, thereby helping to reduce volume discrepancies in construction projects and enhancing the reliability of material quantity planning.
