How Victoria's Big Build
Is Changing BIM
Victorian Transport Digital Engineering (VTDE) is reshaping how BIM is delivered on Victoria's transport infrastructure projects — here's what that means for project teams.
An Australian-first digital transformation
Victoria's Big Build — the state's multi-decade transport infrastructure program — is committed to advancing digital engineering practice across every project it touches. That commitment is delivered through Victorian Transport Digital Engineering (VTDE), described as an Australian-first, multi-year digital transformation program spanning the entire Victorian transport supply chain. The Department of Transport and Planning is transitioning to model-based delivery across its project pipeline, moving the state decisively away from disconnected 2D documentation.
VTDE is not a single document — it's an evolving ecosystem of standards, processes, and tools, including Exchange Information Requirements that set out the digital engineering processes, deliverables, and information requirements expected on Big Build projects, and a Digital Engineering Data Specification governing how that information is structured.
Validation is now automated
One notable feature of VTDE is its Model Validator Tool, which runs automated model-based assessments against IFC 3D models to check the quality of information delivered against the program's digital engineering standards and data specification. In practice, that means models submitted to Big Build projects are checked programmatically, not just reviewed by eye — so getting the underlying data structure right the first time matters far more than it used to.
Separately, the Victorian Health Building Authority (VHBA) has adopted the VBIS (Virtual Buildings Information System) classification standard as a required standard for major health infrastructure projects valued at $20 million or more, extending the same structured-information thinking beyond transport into health infrastructure delivery.
What this means for your project
For consultants and contractors working on Victorian infrastructure or health projects, the practical takeaway is that BIM delivery now needs to be planned around structured, validated data from the start — not treated as a documentation exercise that happens after design decisions are made. neoBIM's ISO 19650-aligned modelling workflows are built around this same discipline, so clients working within VTDE or VHBA frameworks aren't starting from scratch on process.
