Abstract: When analyzing the life cycle of buildings, most of the waste corresponds to the demolition
stage, and its quantification is crucial for efficient management. In this context, the use of
Building Information Modeling (BIM) allows to improve the estimation of demolition waste

(DW), leading to more accurate and assertive information compared to surveys based on two-
dimensional projects, considered therefore, essential for a better management of these waste.

This study presents a use of the Autodesk Revit software, based on its BIM technology, for
the 3D modeling of 13 buildings, prior to their complete demolition, generating DW
volumetric estimates. The values were compared with the estimates of RD volumes resulting
from the application of the indirect visit method (IVM) and the volumes licensed by the
prefecture of Belo Horizonte (PBH). The main functionality of the Revit program used was
the Quantity Take-off (QTO), which corresponds to the automatic extraction of quantities
from a given project. When comparing the QTO with the IVM and the calculations provided
by the PBH, numerous uncertainties justified the differences between RD volume estimates,
but, the results showed that the QTO minimized the errors in relation to the quantification
based on 2D projects.
