Nowadays, Building Information Modeling (BIM) tools offer significant opportunities for automation, integration, and data consistency in the design and management phases of construction projects. This study aims to generate comprehensive quantity takeoff for all critical project components by extracting the concrete and formwork quantities of structural elements—such as foundations, columns, beams, slabs, and staircases—as well as the quantities of walls, doors, and windows from 3D BIM models using Dynamo software. The developed algorithm will be tested on a sample project. Compared to traditional quantity surveying processes, the proposed method provides faster data processing and a reduced error rate, thereby making important contributions to project management and cost control. When integrated with on-site construction practices, the model-based data collection process facilitates decision-making based on up-to-date information. This study underscores the impact of effectively utilizing digital model data in the quantity estimation process, particularly for large-scale construction projects. The findings indicate that systematically integrating tools such as BIM and Dynamo can enhance efficiency throughout construction processes.
