Abstract

Health is an investment for every population in the world as a means of providing health services. Hospital is a derived demand that produces what those needs are. hospital construction will continue to exist in line with the need for health services, so it is necessary to control the cost performance as a determination of the success of a project. Accurate cost estimation before implementing a project is important to prevent cost overruns so that increasing cost performance using the cost method is the focus of this study. To answer the research question, which is to find the factors that most influence the implementation of Building Information Modeling (BIM)-based on Quantity take-off (QTO), the RII tool is used. Statistical analysis by using the Relative Importance Index (RII) has a result in 10 rankings of factors that influence the implementation of BIM QTO, namely drawing, completeness Bill of Quantity (BoQ), TOR & specifications, cost reduction, preparation of activities in the work breakdown structure, cost breakdown, 3D modeling details, Data Interoperability, Quantity Take Off, Subcont & Supplier pricing, and cost database. Study cases with the implementation of BIM QTO on hospital building structures work cost efficiency up to 5.34%.
