Abstract:

"This session will talk about the application of 3D information modeling techniques to linear infrastructure megaprojects, and provide an overview of both benefits and challenges. A common perception in our industry is that solutions to problems which cause infrastructure projects to be delayed and go over-budget are years away, but this misconception causes engineers to overlook existing technologies that, combined with best practices in project management, can improve project outcomes. We will touch upon common objections and ways that currently-deployed technologies are already overcoming them, including the misconceptions that: • A 3D workflow requires extensive retraining. Contrary to popular belief, the ability to use 2D design/drafting methods to create 3D asset models and design deliverables exists today, allowing companies to use deep pools of existing talent. • Structural detailing in 3D and conflict detection is not practical with existing IT hardware. This is a fallacy. New programming structures and cloud computing make it possible to implement full 3D modeling and detailing on major projects without deploying new IT solutions. • Siloed disciplines and communications can only be solved by individual efforts. This isn’t true. Proper design and planning tools can greatly enhance cross-disciplinary communication and coordination, even providing change notification and “enforced contact” between teams. Our presentation will additionally discuss challenges seen when implementing new technology and best practices for overcoming them. We aim to spark in-depth discussion of 3D information modeling techniques, potential applications, and best practices among our audience. "
