Abstract

The rapid growth that occurs in the construction sector is due to the construction sector is one of the important fields in the development of a region or country. This complex development requires construction services to work effectively and efficiently in carrying out their work. The accuracy of work volume calculation is one of the successes of a construction project. Conventional volume calculations can experience errors ranging from human error, inaccuracy, lack of accuracy, and others. The existence of technological developments at this time, with the existence of BIM technology can help solve these problems. The purpose of this research is to compare quantity take off with conventional method and building information modeling (BIM) method. The calculation of quantity take off using the building information modeling method uses Revit 2021 software and is assisted by using Microsoft Excel. The flow of this research is to model the building structure using the revit 2021 application by referring to the detailed engineering drawing. The result of this modeling is the volume of work obtained. The results of this study found that the volume calculation using the building information modeling (BIM) method increased the efficiency of using work materials by obtaining the minimum efficiency occurred in the second floor column work of 0.11% which saved work material by 0.09 m and the maximum occurred in the second floor beam work of 11.54% which saved work material by 10.1m.
