The application of building information modelling (BIM) for cost and time analysis: Bintang Bano Dam, West Sumbawa, Indonesia

Construction projects often have problems with costs, quality, time, and design errors from the planning period
to the construction time. This is because construction projects in Indonesia still use traditional methods. This research
focuses on the use of the method in the field of construction management, namely Building Information Modeling. This
study used 3D modeling software to create a simulation of the spillway structure and generate cost and work volume data.
Then, using scheduling software, it determined the duration of the work. The study found that using BIM methods is more
time-consuming than conventional methods, which is a cost difference of (IDR) 39,653,431.49. The duration of the work
obtained on the 4D BIM model is 540 days. The use of BIM can be said to be more effective and efficient because BIM
can calculate the volume of work in geometric conditions that are more difficult and detailed.
