Framework for extracting project quantities for construction cost estimation using 5D BIM in an openBIM environment

Purpose – 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. Design/methodology/approach – A bibliographic review and data analysis supported the development of the framework. An apparent validation was performed with industry professionals, followed by a comparative assessment of the main BIM tools referenced in the study. Findings – Results indicated convergence between literature concepts and expert perspectives, with both suggesting refinements. The analysed 5th dimension (5D) BIM solutions were better aligned with the framework than lower-dimensional tools, which are still predominant in many of the reviewed works. Research limitations/implications – As a literature-based study, relevant publications may have been missed. Similarly, rapid technological evolution may introduce new functionalities or tools, particularly through advances in artificial intelligence. Practical implications – The framework provides structured guidance for practitioners and researchers on selecting, applying and enhancing BIM tools for quantity takeoff and cost estimation. Originality/value – The study consolidates dispersed requirements into an operational structure and compares them with the software's current capabilities, thereby promoting more reliable 5D BIM adoption. Its distinguishing feature is the proposal of a framework for extracting project quantities at the micro-BIM level within an openBIM environment, where quantities and unit costs are linked to their respective elements in the 3D model.
