This document discusses the use of immersive visualization technology (IVT) in infrastructure projects. It details a three-phase research and application process where IVT was first used on completed models, then live projects nearing completion, and finally an early-stage project. For the early project, IVT allowed 50% more options to be assessed faster and improved stakeholder engagement. While it has limitations like duration and accessibility, overall IVT provides a new platform for more effective project design, review, and decision making. The document concludes by discussing future opportunities to apply IVT beyond 3D for activities like schedule/cost integration, simulation, and operations/maintenance.

Editor's Notes
- #3: Thanks CH2M is a programme management and delivery organisation.
- #4: Pioneering and developing over the last 4 years Background, drivers and need
- #5: Technology emerging as enabler infrastructure projects. Increasing volumes of data, “big Data”. Challenge to capture, store, analyse, share, update, query, secure or visualise BIM is at heart of the digital transformation UK build and infrastructure environment, and core uses 3D models and CDE to drive efficiency of activity around asset delivery and operation.
- #6: model is foundation upon which everything else on the project can build, central repository of information upon which numerous outputs are possible. Data reviewed, and analysed, we can produce drawings, and in a common data environment can run clash detection, and undertake cost estimation. But whilst this looks simple….
- #7: The reality extremely complex. Infrastructure projects with data and processes that are either outdated, inadequate or simply missing, systems used that are different and present interoperability issues, in particular at the interface with more than one client organisation. We needed a new way to communicate ideas amongst our teams. A way that is more “fit for purpose” in the BIM era
- #9: Year long innovation initiative – 6 workshops 70 attendees Industry engagement activities Understand what the visualisation challenges were Discuss ways to resolve them Collaborate outside the competitive project environment
- #10: Adding dimensions make us more efficient but it creates new challenges. Teams need new innovative ways to communicate this information. Middle East station anecdote CH2M has been developing and applying immersive visualisation technologies for the past 4 years and we are increasingly finding additional benefits to these innovations as the technology develops.
- #11: Immersion provides benefits beyond the traditional “desktop” visualisation tools: Step inside a giant VR headset better perception of a data geometry –beats software driven interference checking more intuitive data understanding – catches physical and operational issues better retention of the perceived relationships in the data
- #12: use of such technologies throughout the project life cycle. added value in different stages.
- #15: CCTV camera example for ‘Design for Operation’ – that is where the government sees the real benefit of BIM. The usage of IVT for project controls.
- #16: Managing conflicting stakeholder requirement in immersive environment, assessing entrance location and daylight impacts . The usage of IVT for project controls .
- #18: Lessons learnt from phase 1 and 2 supported seamless model configurations for use within the immersive environment.
- #19: Allows simplified visualisations of technical issues to non technical audience, or in a multi disciplinary project to differing technical expertise.
- #20: Temptation to want to review more options, or look at more detail, whilst Igloo very mobile, for one off projects practicality not easy, can it become the tool of choice? If there are errors on engineering model not as ready to interrogate in immersive environment
- #21: Stakeholders were walking in the shoes of the end users
- #23: Graphical construction simulation of cost and schedule data Compelling visuals to demonstrate impact on baseline from decisions Faster, more informed decision making
- #24: Simulation of pedestrian flows algorithms Fire simulation New design layouts
- #25: HS2 BIM Room digital area to interact with the model.
