A Comparative Analysis of Traditional and BIM-Based Quantity Takeoff Methods in Construction Projects

Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the comparative analysis of traditional quantity takeoff methods and Building Information Modeling (BIM)-based quantity takeoff methods in construction projects. The study aims to evaluate the efficiency, accuracy, and overall effectiveness of these two approaches in quantifying materials and estimating costs in construction projects. The research methodology involved a thorough review of existing literature, case studies, and interviews with industry professionals to gather insights and data for analysis. Chapter One provides the introduction to the research, including background information on quantity surveying methods, the problem statement, objectives of the study, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter Two comprises a detailed literature review that explores the historical development, principles, advantages, and limitations of traditional quantity takeoff methods and BIM-based quantity takeoff methods. The chapter also discusses the current trends and applications of these methods in the construction industry. Chapter Three outlines the research methodology adopted for this study, including the research design, data collection methods, sampling techniques, data analysis procedures, and ethical considerations. The chapter also describes the tools and software used for the comparative analysis of traditional and BIM-based quantity takeoff methods. Chapter Four presents a detailed discussion of the research findings, including a comparative analysis of the efficiency, accuracy, and cost-effectiveness of traditional and BIM-based quantity takeoff methods. The chapter also highlights the key factors influencing the adoption and implementation of these methods in construction projects. The conclusion and summary in Chapter Five provide a comprehensive overview of the research findings, implications, and recommendations for industry practitioners, researchers, and policymakers. The study concludes that while traditional quantity takeoff methods are still widely used in the construction industry, BIM-based quantity takeoff methods offer significant advantages in terms of accuracy, efficiency, and collaboration among project stakeholders. The thesis contributes to the existing body of knowledge by providing valuable insights into the benefits and challenges of adopting BIM-based quantity takeoff methods in construction projects. In conclusion, this thesis underscores the importance of embracing technological advancements such as BIM in quantity surveying practices to improve project outcomes and enhance overall project performance in the construction industry. Further research is recommended to explore the long-term impacts and scalability of BIM-based quantity takeoff methods in construction projects.
