Abstract

Building Lifecycle Management (BLM) has emerged as a pivotal approach to managing the complex and evolving demands of buildings throughout their entire life span from initial conception and design through construction, operation, maintenance, renovation, and eventual decommissioning. This comprehensive overview synthesizes the multidisciplinary components of BLM, offering a structured examination of its frameworks, methodologies, technologies, and applications across the building lifecycle. The paper explores how BLM integrates principles from architecture, engineering, construction, facility management, and information systems to foster improved decisionmaking, enhanced sustainability, cost-efficiency, and regulatory compliance. Central to BLM is the concept of datacentric management, enabled by technologies such as Building Information Modeling (BIM), Digital Twins, Internet of Things (IoT), and cloud-based platforms. The abstract outlines how these tools support seamless information flow across stakeholders and lifecycle stages, thereby reducing inefficiencies, enhancing collaboration, and supporting predictive maintenance and energy optimization. Additionally, the paper addresses current challenges in BLM implementation, including data interoperability, stakeholder alignment, cybersecurity, and the need for skilled professionals. By presenting taxonomy of BLM stages, identifying key actors, and mapping out critical information exchanges, this overview serves as a foundational reference for academics, practitioners, and policymakers. It also evaluates emerging trends such as artificial intelligence, circular economy principles, and smart infrastructure integration. The paper concludes with strategic recommendations for advancing BLM adoption and fostering a sustainable built environment.
