Thesis Overview

The project titled "A Comparative Analysis of Traditional and BIM-Based Quantity Takeoff Methods in Construction Projects" aims to investigate and compare the efficiency, accuracy, and overall effectiveness of traditional quantity takeoff methods versus Building Information Modeling (BIM)-based quantity takeoff methods in construction projects. Quantity takeoff is a crucial process in construction estimating, involving the measurement and calculation of quantities of materials required for a project. The construction industry has seen a gradual shift towards digital technologies such as BIM, which has revolutionized the way construction projects are planned, designed, and executed. BIM enables a comprehensive digital representation of the physical and functional characteristics of a project, allowing for better coordination and collaboration among various project stakeholders. However, despite the numerous benefits associated with BIM, traditional quantity takeoff methods are still widely used in the industry. This research seeks to provide a comprehensive analysis of both approaches to quantity takeoff in construction projects, with a focus on identifying their respective strengths, limitations, and impacts on project outcomes. The research will involve a detailed literature review to explore the current state of traditional quantity takeoff methods and BIM-based quantity takeoff methods. This review will examine existing studies, methodologies, tools, and technologies related to quantity takeoff in construction projects. Furthermore, the research methodology will involve a comparative analysis of traditional and BIM-based quantity takeoff methods through case studies, surveys, and interviews with industry professionals. The aim is to gather empirical data on the performance, accuracy, cost-effectiveness, and time efficiency of both methods in real-world construction projects. The findings of this research are expected to provide valuable insights into the advantages and challenges of traditional and BIM-based quantity takeoff methods. By comparing these approaches, the research aims to inform construction practitioners, project managers, and decision-makers on the most suitable quantity takeoff method for enhancing project efficiency and productivity. Overall, this research project will contribute to the ongoing discourse in the construction industry regarding the adoption of digital technologies like BIM and their impact on traditional construction practices. It will also shed light on the potential benefits of integrating BIM-based quantity takeoff methods into construction projects, ultimately aiming to improve project outcomes and industry practices.
