The growing intricacy of infrastructure and high-rise construction projects has necessitated a paradigm shift in traditional building engineering methodologies. Increasing demands for architectural innovation, sustainability, and project efficiency have underscored the limitations of siloed workflows and conventional communication frameworks. In response, Building Information Modelling (BIM) has emerged as a cornerstone of digital transformation in the architecture, engineering, and construction (AEC) industry. By enabling the creation and management of multidimensional, data-enriched models, BIM fosters an integrated approach to design, execution, and facility management across project lifecycles. This paper critically examines the influence of BIM-driven collaboration on the advancement of building engineering in complex infrastructure and vertical construction. The study investigates how BIM-enabled environments facilitate enhanced coordination among multidisciplinary stakeholders—architects, structural engineers, MEP specialists, and contractors—thereby reducing design inconsistencies, optimizing construction sequencing, and minimizing project risk. Key processes such as clash detection, real-time updates, and parametric modelling are analyzed for their impact on project performance indicators including cost, time, and quality. In addition, the research addresses the institutional, technical, and contractual enablers of effective BIM adoption, highlighting the role of integrated project delivery (IPD), common data environments (CDEs), and collaborative governance models. Case-based evidence is used to demonstrate BIM’s role in reshaping engineering practice, particularly in projects involving high-density urban environments and complex structural geometries. The findings affirm that BIM not only improves design accuracy and construction productivity but also facilitates the transition toward smart, resilient, and lifecycle-optimized infrastructure systems.
