The 2023-24 QLD State Budget saw the allocation of some funding to progress an investigation into a digital twin with proof of concept and program implementation plan providing valuable insights into the benefits of data and technology for infrastructure planning and delivery.

Spatial WA is a whole of government, digital initiative that will leverage the State’s data in one platform and provide the tools for Government to better plan, design, test and collaborate using a highly accurate virtual environment.

The NSW Spatial Digital Twin (SDT) is a program of work that is being led by DCS Spatial Services which will deliver a cross-sector, collaborative environment that will share and visualise location information, in a 4D model (3D plus time) of the real world, in near real time and will support improved decision making.

The Digital Twin Victoria program is a record $37.4 million investment in digital twin technology, geospatial data and spatial innovation over 4 years. The program is helping to set the digital foundations for a future-ready Victoria, using data to answer new questions and make better data-led decisions. Our vision is to create Victoria online by 2024, so that government, industry and the community can collaborate through shared open data, technology and algorithms, to enhance real world outcomes and position the State as the data and innovation capital of the region.

FIRST-EVER NYSDOT project where 3D model issued as legal contract document (awarded Spring 2020, under construction). Represents next generation pilot advancing BIM use – model becomes legal contract document vs 2D plans. Agency documenting lessons learned. Eliminates/minimizes paper plans, requires bidders use digital copy, 3D model entire project containing topography, geotechnical, roadway, bridge information. Second project model-based contract planned Spring 2021. Breakthrough: model IS the contract.

For DBB projects: NYSDOT generates designs in 3D model in-house, converts model, delivers work as 2D information. Contractors then use 2D to reconstruct necessary 3D details. Process challenging due to incomplete/inaccurate information during 2D-to-3D conversions. Recognizing need robust data management strategy facilitate seamless exchange information through digital-as-builts (DABs) during transition to digital workflows. Consequently seeking specify work using various electronic file formats potential minimize/eliminate data loss during information transfer. Past decade particularly following 2011 GIS implementation improved integration DAB processes/construction as-built data.

EARLY PILOTS: Creating accurate geometric models roadways, utilities/drainage, 3D solids some bridge elements. Intended uses: help construction activities automation tools stakeout, AMG, inspection verification, quantity measurements. LATER PILOTS: Tested capture 3D digital as-built models real time exported GIS. 2014: Kosciuszko Bridge first DB contract with BIM requirements, piloted 4D models. KEW GARDENS: Next large complex project with BIM requirements (focus case study). MODEL-BASED DELIVERY: Route 28 bridge first 3D model becomes legal contract document (Spring 2020 awarded). Second model-based planned Spring 2021. Progression: geometric modeling → as-built capture → 4D scheduling → model-as-contract.
