| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | Building Information Modelling (BIM) has been fully integrated to Architecture, Engineering, and Construction (AEC) industry of some developed nations, improving project delivery efficiency. BIM provides more than just 2D documentation and 3D visualization, motivating this research to explore the potential of BIM in generating Quantity Take-Off (QTO) in building projects in Nepal. Additionally, the accuracy of BIM-based QTO is compared to traditional and actual QTO. The study aims to evaluate the performance of existing BIM models in generating QTO and to enhance the precision of BIM-based QTO. The research was based on a total of four case studies, two of which involved the collection of BIM models. These models, reviewed for accuracy and completeness, were used to generate QTO data without any modifications made to them. The resulting data provided insight into the scenario of BIM models being used in Nepal. For the remaining two case studies, BIM models were created and checked for errors using model checking tools. Once errors related to properties and physical quantities were resolved, QTO data was generated and compared to traditional and actual QTO. The results indicated that the BIM-based QTO is higher than both traditional and actual QTO when not checked, due to clashes and duplicates mainly in walls. The accuracy of BIM-based QTO is primarily influenced by (i) the accuracy and completeness of the model, and (ii) the proper definition of model elements. The research suggests that accurate BIM-based QTO can be achieved by (i) creating detailed guidelines for model creation, (ii) using standardized BIM object libraries and templates, and (iii) using model checking software to check errors. The findings show that Checked BIM-based QTO is more precise than Traditional QTO. The findings of this research contribute to understanding the performance of BIM models in generating QTO and provide recommendations to improve the accuracy of BIM-based QTO in building projects in Nepal. |
