4D BIM-Based Master Scheduling for Giga-Projects: Improving Schedule Reliability and Stakeholder Alignment
Abstract
Giga-projects operate under extreme conditions of scale, uncertainty, and interdependence. Their delivery is shaped by long supply chains, multi-package procurement, geographically dispersed teams, regulatory interfaces, and client ambitions that are often revised while construction is already underway. Under these conditions, master schedules frequently become static reporting documents rather than dynamic management instruments. Four-dimensional building information modeling (4D BIM), which links time information to three-dimensional digital models, has been increasingly positioned as a means of transforming master scheduling from a document-centered process into a visual, data-driven and collaborative control system. This review paper synthesizes recent literature published between 2020 and 2026 to examine how 4D BIM-based master scheduling contributes to schedule reliability and stakeholder alignment in giga-project environments. Following an evidence-led review procedure adapted from the structure and methodological logic of the sample article provided by the user, the paper analyzes recent studies on 4D BIM scheduling, megaproject integration, BIM-enabled stakeholder management, lean-BIM integration, progress monitoring, digital twins, and AI-supported schedule control. The review finds that 4D BIM improves schedule reliability through better work-package decomposition, improved constructability analysis, richer look-ahead planning, enhanced progress verification, earlier identification of spatial-temporal clashes, and stronger change-response capacity. It improves stakeholder alignment by creating a shared visual language, structuring information exchanges, clarifying interface dependencies, and supporting collaborative decision-making across owners, designers, contractors, consultants, and digital control teams. However, the literature also shows that these gains are not automatic. Their realization depends on model maturity, information governance, schedule coding standards, contractual alignment, staff capability, and integration with lean planning and real-time site data. The paper proposes a synthesized review framework that positions 4D BIM master scheduling as a socio-technical capability rather than a software feature. It concludes with implementation recommendations and future research priorities relevant to giga-project delivery organizations.
