Debate Continues: BIM versus GIS

I recently had the pleasure of participating in a panel discussion entitled, “The Great BIM versus GIS Debate”. This 90-minute session in front of a packed room was moderated by Matt Ball (@SpatialSustain) and proved to be a lively (and sometimes heated) discussion between myself (@engis), Pete Southwood (@Geo_Pete) and members of the audience. Issues addressed in the debate encompassed technology; data accuracy, access, integration and analysis; collaboration and efficiency; and the future of GIS and BIM.

I introduced this debate during a previous blog post which you can find here. However, if you were unable to attend or simply want to review some of the highlights, I encourage you to check-out the following:

Dale Lutz (@DaleAtSafe) posted his thoughts on the debate here. Although there was no clear knock-out punch by either opponent, he did include a list of the best (and some would say hilarious) “zingers”.

Matt Ball (@SpatialSustain) posted his thoughtful perspectives of the debate here. His great summary covers “Concepts or Tools”, “Point of Truth” and “Integrated Infrastructure Information”.

I’ve also posted a replay of “The Great BIM versus GIS Debate” to YouTube. For those of you wanting to review the debate in its entirety, I’ve made a recording of the complete 90-minute session which I divided into chapters which you can access via the links below:

The Great BIM versus GIS Debate

Are you a GIS professional convinced that GIS is the technology of choice for mapping and analyzing the world we live in?

Are you an engineer or architect with years of CAD experience confident in your abilities to create cost effective and sustainable designs?

Regardless of which camp (GIS or CAD) that you may be a part of, “The Great BIM versus GIS Debate” is sure to be a lively session at Autodesk University this year.

GIS gives us a way of mapping, analyzing and managing our real world assets within a geospatial context. It gives us a way of integrating and relating seemingly disparate data sets based on geography. GIS is a tremendously useful planning tool that helps provide us with insight into our infrastructure projects in a way that traditional CAD technology cannot.

BIM is similar to GIS in some ways. If you are unfamiliar with BIM as it applies to infrastructure then I encourage you to check out a detailed explanation in my previous blog post. Simply put, BIM is Information Modeling for the Built environment. It’s is a process - not software - a process that lets you explore the physical and functional characteristics of your project digitally, before it’s built. At the heart of BIM is an information model – a model that is used throughout the infrastructure lifecycle – a model that is passed from planning and conceptual design phases to detailed design, construction and then to management phases. As a result, the application of the BIM process can lead to significant time and dollar savings during construction and additional savings throughout the life of the asset as a result of better more sustainable designs.

So, when it comes to supporting the infrastructure lifecycle, which is better? BIM or GIS. Both BIM and GIS have their advantages; both have their supporters.

Well, if you’re unsure about BIM as it applies to GIS or visa-versa, then I encourage you to check out the “The Great BIM versus GIS Debate” at Autodesk University. This panel session will be moderated by Matt Ball (@SpatialSustain). Peter Southwood (@Geo_Pete) and I (@engis) will be opposing each other on behalf of the two camps: GIS and BIM. With what I am sure will be provocative questions from Matt Ball and audience members, Peter and I will feel the heat as we do our best to respond to questions encompassing technology; data accuracy, access, integration and analysis; collaboration and efficiency; and the future of GIS and BIM.

Better Infrastructure Planning with AutoCAD Map 3D – AU Virtual

If you are unable to travel to Las Vegas to attend Autodesk University in person this year, you can still participate virtually by registering for AU Virtual. It’s free and only takes a moment to register.

And while on-line with AU Virtual, why not make a point of catching my virtual session, entitled “Better Infrastructure Planning with AutoCAD Map 3D”. Attend this session to see how you can turn today's planning and design challenges to your advantage with Building Information Modeling (BIM) and a more powerful and productive AutoCAD Map 3D.

BIM for infrastructure is creating a cultural shift in infrastructure planning and design workflows. Increasingly, infrastructure planning and geospatial professionals working on transportation, utility, and other infrastructure projects are being asked to integrate planning data with BIM models to more directly represent as-builts and better leverage "GIS ready" design data. Attend this virtual session and discover how AutoCAD Map 3D can help.

AU Virtual, Class GS5581. Tune in on November 29, 2011.

Model Your World

Last year, in honor of GIS Day, my colleagues and I created a webcast that highlighted Building Information Modeling (BIM) and its impact on the geospatial community. I also blogged about this topic a short time later via GIS User.

This year, for GIS Day 2011 and consistent with the BIM and GIS themes, I created an on-demand webcast that highlights Autodesk Infrastructure Modeler – a new geospatially enabled, 3D conceptual design tool from Autodesk.

With Autodesk Infrastructure Modeler, explore “what could be” in the context of “what is” whether you’re:

• An architect interested in site development and the placement, orientation and shape of a new building
• A municipal planner examining the impact of new land use and zoning policies on the city skyline and local neighborhoods
• A transportation planner or civil engineer exploring options for a new highway corridor
• A campus authority looking for more compelling, non-technical ways to communicate proposed re-development ideas to project stakeholders
• Someone involved in conceptual design, 3D GIS, or BIM

View this webcast to see how you can incorporate existing 2D CAD, GIS, BIM, and raster data to quickly create 3D models that more realistically depict the local environment.

Learn how you can easily evaluate multiple design alternatives in the context of the existing environment by overlaying GIS data and using infrastructure sketching and proposal management tools.

See how you can communicate visually rich proposals of these alternatives with interactive navigations, rendered images, and recorded videos.
