Abstract

Building Information Modelling (BIM) is a system for digitizing data processing that can help work in the construction industry run more effectively and efficiently. One type of BIM is 5D BIM. 5D BIM has the function of determining the take-off quantities and analyzing the costs of a building. An example of 5D BIM is Cubicost. Cubicost BIM is a BIM from the Glodon company that allows you to calculate work volumes in a detailed and precise way. In this research, the case study presented is an architectural work on the Waras Wiris Boyolali Hospital Emergency Building Construction Project. The architectural section was selected because architectural works play an important role in nominal terms, so the determination of volume greatly influences construction costs. This research uses Cubicost TAS and TRB software. Cubicost Software's volume results have also been validated so that they show a 99% correlation figure with volume obtained from conventional calculations. Based on the research carried out, the cost of using Cubicost software for architectural works in the Waras Wiris Boyolali Emergency Hospital Building Construction Project is Rp. 1.695.645.165,47. Using the Cubicost software also produces an efficiency of 11.550% on RAB from the consultant.

Abstract

Engineers increasingly use project management technology such as Building Information Modelling (BIM) to optimize resource utilization and minimize costs in construction projects. Cubicost is a 5D BIM software used for volume and material price calculations. This research aims to compare architectural work volumes using Cubicost Takeoff for Architecture and Structure (TAS) with contractor volumes and conduct a comparison analysis of the Budget Plan (RAB). This study employs a quantitative method through a simple linear regression approach to validate Cubicost results with the author's manual calculations. First, data is collected to be modeled using Cubicost software. Then, a simple linear regression analysis is conducted to assess the validity of Cubicost based on the author's manual calculations. Next, a comparison of volumes and RAB between Cubicost results and contractors is performed to analyze deviations caused by contractor human error factors and determine the percentage of efficiency in Cubicost software usage. The comparison of Cubicost with the contractor results in a cost efficiency of Rp734,925,053.97 or an efficiency percentage of 18.429%. Based on these results, this research recommends the implementation of Cubicost in the construction project of the Integrated Multi-Matra SBSN ISI Surakarta Laboratory Building for decrease human error in this project.
