Integrating 5D BIM into large rail projects improves cost management but faces challenges related to technology, functionality, and governance. This paper presents a framework to support financial decision-making, project management, and efficient delivery.
Key elements include project governance, BIM policies, digital platforms, BIM LOD, cost-estimation classification, and continuous improvement. Governance ensures structured implementation, policies maintain quality, and digital platforms enable collaboration. Cost-estimation aligns with project scope, and continuous improvement enhances efficiency and innovation.
The study, based on Victorian rail projects, highlights challenges such as inconsistent data exchange standards, compatibility issues with cost management, and unclear governance strategies. Further validation in real-world projects is recommended.
The BIM Manual and supporting documents outline strategic processes and workflows for Rail Baltica and its supply chain, evolving over the project lifecycle to integrate technological and methodological advancements. The manual applies to all project phases, as defined in the Employer Information Requirements (EIR/TS), ensuring a consistent framework for BIM delivery.

This report by buildingSMART is an official IFC Rail Project (Phase I) deliverable, referenced by the Requirement Analysis Report and Conceptual Model Report. It outlines the effort to extend the IFC schema to include the requirements of rail infrastructure. The document provides a detailed framework for incorporating these requirements into the IFC model, ensuring alignment with the rail industry’s specific needs.

This document is the first official deliverable of the IFC Rail project, outlining railway requirements for extending IFC. It defines the IFC Rail Reference Process Map, key use cases and priorities, and general modelling requirements (alignment, spatial structure, etc.). It also includes Model View Definitions (MVDs) to guide implementation.
