Here's a great article forwarded to me by my Director of Implemenation Services and a former CAD Manager
BIM is a disruptive technology. Revit is a disruptive tool.
According to Wikipedia ” A disruptive technology or disruptive innovation is a technological innovation, product, or service that uses a “disruptive” strategy, rather than a “sustaining” strategy, to overturn the existing dominant technologies or status quo products in a market. Disruptive innovations can be broadly classified into low-end and new-market disruptive innovations. A new-market disruptive innovation is often aimed at non-consumption, whereas a lower-end disruptive innovation is aimed at mainstream customers who were ignored by established companies. Sometimes, a disruptive technology comes to dominate an existing market by either filling a role in a new market that the older technology could not fill (as more expensive, lower capacity but smaller-sized hard disks did for newly developed notebook computers in the 1980s) or by successively moving up-market through performance improvements until finally displacing the market incumbents (as digital photography has begun to replace film photography).”
BIM is displacing CAD in some arenas. Or at the very least it is attempting to fulfill the promise of CAD.
As such, BIM requires a new way of thinking and challenges the status quo. Here are a few areas that I see as being disrupted by Revit.
Workflow - just the way we get things done is impacted by BIM. BIM demands that we change the way we work. No longer can we use the tried and true. We must create a “new true”. Approaching BIM from a CAD mindset may get you into trouble. It may prevent you from seeing any benefit from Revit. Trying to fit Revit into your CAD world is like Ross trying to get back into his leather pants.
Old Habits - Toss them out. We need to create new habits. The old ones don’t work anymore. Working in Revit will force changes on the old way of doing things.
Project Teams - they are smaller than on CAD projects. Two or three people can do the work of 5-6. Because Revit does so much with so few software demands, there is no need for multiple people doing the same thing.
Coordination - With Revit and tools like NavisWorks and IFC’s and links to other Revit models and SketchUp, coordinating between disciplines and others becomes easier.
Levels of Design Detail - Where do you draw the line? Since we are no longer drawing lines, we need to define what is enough, not enough and too much detail in a model.
Financial Flow - changes to when the labor hours are spent and billing the client earlier in the process have to be rethought. If 25% more of your hours are going into SD and DD phases, you will be chasing the dollars unless you bill the client sooner.
Many more areas need to be investigated again as we move deeper into the tools for BIM and change the workflow of our design teams.
CAD Manager - get with it. There is a lot of change happening in the design world. None of it can just be ignored like the spare change on your dresser or the bottom of your purse.
If you are in an industry that is embracing a tool like Revit, then you need to get with the program and start changing for the new times.
CAD Managers must not get stuck in a 2D world.
I know many CAD Managers that have been doing 3D for years. They have taken their firms and themselves to the next level already. They are at the forefront of the technology push and are actually leading the way. The title CAD Manager does not mean that the only tool you use and promote is 2D CAD. There are some new titles that are popping up, like BIM Manager and BIM Model Coordinator, but they are redefinitions of CAD Manager roles. It is a manager that is needed.
This kind of dramatic change has happened before.
While it may be true that the current advancement in software functionality is dynamic, there have been many such transitional phases that we have migrated through. Board drafting to CAD, the introduction of reference files, the use of Paper Space and now the move to 3D/BIM. Transitions happen all the time. Some may be small steps and others wholesale overturning of the status quo. Revit use demands that we stop thinking in terms of linear CAD processes and think spatially. Start thinking in 3D.
Change must be managed.
And who better to do that than someone who has “been there, done that”. CAD Managers are use to focusing and managing change. They do it all the time. Changing to a 3D tool may require you to think outside the 2D box. Don’t get stuck in a Layer List. Move into Property Management. Become “Family” friendly.
