What is it about?
Quantity surveying in BIM still lacks standardization, compromising the accuracy of results, especially in 5D BIM. We propose a literature-based framework to organize this process and evaluate its adherence in the main software on the market. Validated by experts and analysed in a case study, the study demonstrates alignment between theory and practice and indicates that 5D solutions are more suitable, reinforcing the need for greater standardization.

Why is it important?
The framework provides structured guidance for practitioners and researchers on selecting, applying and enhancing BIM tools for quantity takeoff and cost estimation.
Perspectives
This study aims to develop a framework for quantity takeoff from Building Information Modelling (BIM) models based on the requirements identified in the literature for the process, as well as to evaluate the ability of the main BIM software available on the market to meet the requirements proposed in the framework.
