Evaluasi Volume Pasangan Dinding Menggunakan Clash Detection Pada Proyek Hotel Marriot Gelora

The development of digital technology has a positive impact on the construction  world, which plays an important role in economic growth and employment. The complexity  of construction work requires good project management and coordination to simplify and  minimize errors in the construction and supervision process. One technology that can be  implemented in construction work is Building Information Modeling (BIM). This study uses  a quantitative method using BIM software, namely Autodesk Revit for 3D modeling and  Autodesk Navisworks for analyzing collisions (clash detection). Data collection techniques  are carried out by receiving detailed engineering drawing (DED) data from consultants,  3D model structures, architecture and a recapitulation of project cost estimates. The use  of BIM in the Marriot Gelora Jakarta hotel project specifically to emit basement wall  volumes uses the clash detection method found in Autodesk Navisworks software. Clash  detection analysis is only carried out on the basement floor (B4 - B1M). A clash case is  created related to the volume of the basement architectural wall. Based on the results of  the calculation of the budget plan for the basement floor architectural wall work before  and after clash detection, it can be concluded that the use of BIM clash detection  technology can save budget costs of Rp. 82,191,346.13.
