Introduction

This chapter introduces the book, which explores the implementation of Building Information Modeling (BIM) during operation and maintenance (O&M) phases. It starts by outlining the main problem the book addresses and underlines the critical importance of the O&M phases in a project's lifecycle. The chapter then outlines the research aims and objectives, which center on enhancing building performance and occupant comfort through the interoperable integration of BIM and Decision Support Systems (DSS). Moreover, the chapter offers a comprehensive overview of the study's scope. It specifies the aspects of building performance under examination, particularly in relation to maintenance efficiency and the management of building systems such as HVAC, which have a significant impact on energy usage and occupant health. It also outlines the research limitations, including the specific focus on certain building types and the use of particular software tools for risk analysis and BIM. Furthermore, the chapter presents the overall structure of the dissertation, guiding the reader through subsequent chapters that elaborate on state-of-the-art facility management practices, the development of the DSS, and the integration of BIM with these systems to enhance operational strategies. This introductory chapter paves the way for a comprehensive discussion of BIM's potential to streamline data integration and support decision-making processes in building maintenance, ultimately aiming to optimize both operational efficiency and occupant comfort.
