Assessing the Effectiveness of Photogrammetry in Land Cut and Fill Analysis: A Comprehensive Review Based on Case Study of the Trans Sumatra Toll Road Project
摘要
PT Hutama Karya is advancing the second phase of the Trans Sumatra Toll Road mega project, specifically the Sicincin-Lubuk Alung Padang Section which spans 40 km. The project encounters challenges, such as volume losses in cut and fill processes due to reliance on traditional surveying methods like total stations. To improve efficiency, the adoption of digital surveying technologies is proposed. This paper reviews the effectiveness of photogrammetry in managing cut and fill volumes, a tool that, when integrated with Building Information Modeling (BIM), enhances geospatial analysis. It highlights photogrammetry’s accuracy in representing landforms and its advantages over traditional methods, including cost-efficiency, faster data acquisition, broader coverage, and reduced resource use for survey activities. Case studies demonstrate photogrammetry’s successful application across various terrains and scales, reducing time by 50% and achieving minimal volume deviation (0.45%) and minor elevation differences (3–5 cm). These benefits underscore photogrammetry’s significant value in modern construction technology.
