ABSTRACT

Digital transformation in infrastructure project planning encourages the integration of spatial technologies and building information modeling. This study aims to develop a GIS–BIM integrated model for tourism infrastructure planning to support digital project planning in Lampon Beach, Banyuwangi. The research employed a model development approach consisting of spatial analysis using DEM SRTM and GIS, contour integration into BIM Revit, and model-based quantity take-off and cost estimation. The spatial analysis indicates that the selected site has an elevation of 0–5 meters, hard soil conditions, and complies with coastal setback regulations (≥100 meters). The BIM model produced a 3,850 m² siteplan with a total building area of 469.8 m² consisting of a mosque, toilets, gazebos, and kiosks. The total estimated construction cost is IDR 1,056,674,768 based on the 2022 Banyuwangi Unit Price Analysis with a 10% overhead cost. The GIS–BIM integration improves location accuracy, design efficiency, and cost estimation reliability compared to conventional 2D-based planning methods. This study contributes to the development of a digital-based tourism infrastructure planning methodology and demonstrates that spatial analysis integrated with BIM enhances data-driven decision-making in infrastructure project planning.
