ABSTRACT
Building Information Modeling (BIM) stands as a revolutionary force in the construction industry, delivering advanced tools for project management and design. Despite its widespread adoption, a critical gap persists in the literature regarding the accuracy of Quantity Take-Off (QTO) outcomes produced by BIM software, notably on platforms such as Nemetschek Allplan. This study seeks to fill this void through an in-depth comparative analysis of QTO accuracy, utilizing Mean Absolute Percentage Error (MAPE) as the benchmark. The Silam Bridge serves as a singular and comprehensive case study, utilizing the Detail Engineering Design (DED) as the foundational basis for material estimation. Executing 3D modeling and reinforcement detailing through the Nemetschek Allplan software, the research unravels notable disparities in QTO precision. Concrete components exhibit a 7.09% deviation, while reinforcement details show a significant 14.87% discrepancy. These findings underscore the imperative for a nuanced understanding of factors influencing QTO accuracy within BIM applications. Beyond merely identifying discrepancies, the study offers valuable insights that hold the potential to enhance construction project management practices. By emphasizing the need to refine BIM-based approaches, this research contributes to the ongoing evolution of the construction landscape. As the industry continues to transform, addressing these nuances becomes paramount for harnessing the full potential benefits that BIM can bring to modern construction practices. In conclusion, this study not only advances the discourse on BIM's efficacy but also provides practical implications for its application, paving the way for improved efficiency and accuracy in project delivery.
