Read this BEFORE Transitioning to _________!

18 May , 2012  

I’ve gotten so many questions about how to learn Revit, what technology to buy, etc. lately and so I wanted to respond in what might initially sound like a surprising way…STOP!!!  Don’t stop asking, and don’t stop pursuing, but stop and think and ask yourself a question: Why?  Why am I learning Revit?  Why am I purchasing expensive technology?  Otherwise, you’re just throwing money at something that you’re hoping at some point you’ll understand.  Not to sound like Mr. Miyagi or anything, but, understand first, purchase after.  Revit Essentials or Advanced?  12 gigabytes of RAM or 24?  You certainly don’t need to understand all the ins and outs of your company’s transition to BIM, but strategize a bit.  What are you trying to accomplish?  Do you even know why you want to go from CAD to BIM (and your answer shouldn’t be because everyone else is).  And it also can’t just be because the project requires it.  Do you understand the difference between Revit and BIM?  You shouldn’t be transitioning from AutoCAD to Revit.  You should be transitioning from a CAD-based project process (which used AutoCAD) to a BIM-based project process (which uses Revit – among a lot of other applications).  You need to take two approaches: project process AND technology.  Your project process WILL change.  How and what pace is up to you.  Your technology will need to change also, but you should understand why before you purchase it.  And when buying more powerful technology for the new software and processes you’ll be going through, don’t buy cheap.  And I say that because “cheap” will WILL WILL cost you in the long run.  I promise you it will.  You can buy inexpensively, and you can find deals, and even negotiate, for what you need.  If you’re purchasing for commercial purposes, technology shouldn’t be free.  You will spend more time getting “free” things to work for you and your business and, again in the long run, it won’t be worth it.

Now, you may be asking yourself, “why is Scott ranting like this?”  For too long now technology has been an after thought.  It has been thought about and budgeted for way past when it should be and you end up backing yourself into a corner.  Then you either buy too much, or even too little, of what you need.  But Scott, you say, why is anything you’re saying new?  Hasn’t it been important to plan for technology all along?  Of course it has, but these days the change in technology is not simply an upgrade in software or a better graphics card.  With the introduction of the Cloud and new found abilities to move design and construction data between different analysis applications to improve outcomes, we are once again finding ourselves both having to adjust our processes AS WELL AS investigate new process that can make our work more efficient and more effective.

In the World of Software, or Really any Process, Migration, is Idealism Wrong?

5 Jun , 2011  

In recent weeks I’ve been told that I am idealistic and that I wear my ideals on my sleeve.  My answer was that in my job, I had to be.  But it made me start to think about how any big change happens.  Usually, it’s a small group of people who, not only have a unique vision of how things should be but, more importantly, know how to implement that change.  It reminds me of a quote from Margarey Mead, “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”  If people who are trying to direct and implement change become intimidated, or doubltful, or waver on the belief that their ideals are right and worth achieving, then they have already lost.  So this post is for people who are in my role throughout the world: do not stop trying to achieve the ideals that you believe in.  While we all work as individuals trying to improve ourselves and our companies, each achievement that each of us makes in the service of a transition to a new and better way of working, helps all of us.

Shifting to Building Information Modeling: Don’t be Afraid to Make Big Changes

13 Apr , 2011  

On June 12th of 2009, the United States government mandated that television stations nation-wide must broadcast exclusively in digital format. Did some people have difficulty with this transition (i.e. rural communities, the elderly, etc.)? Yes. Did the government make an effort to help with the transition (i.e. vouchers to be used towards a low-cost converter box)? Yes. Was this transition necessary? Of course. Why? Because sometimes a society needs to be pushed a little bit in order to make it over a large hump. The transition to digital broadcasts was not the end of the story, it was the beginning. By requiring the use of digital broadcasts, other technologies developed by the marketplace could finally move forward, which benefited the entire country, because they relied on the digital signal. The point of this is that, like the digital broadcast mandate, the design and construction process of Building Information Modeling is just the beginning of a transition which will usher in a whole host of better designs and more efficiently constructed and performing buildings. We just need to draw a line in the sand and then hurl ourselves over it. To be clear, I am by no means saying that BIM is a panacea. It’s not. If for no other reason, there are new hardware and software technologies, as well as other new processes, which haven’t been developed yet. The point is, though, that those things can’t be developed until BIM, as a process, is implemented throughout more of the AEC industry.

I know I’ve said this before, but it bears repeating: the transition to BIM is not as simple as uninstalling AutoCAD and installing Revit. BIM is an overhaul which requires huge changes including schedule, staffing and fee shifts, time for training and a learning curve (which will be a different lengths for each sector of the AEC industry) and the time to develop resources so we can reach our potential. These resources can include content, standards, data/information exchange and process development (i.e. how to we use BIM to determine environmental impact? How to we perform the test fitting task to understand which space is the right one for our client? How to input and then extract the right types of object data in order to perform highly accurate cost estimations?).

Understand what your work environment will look like when BIM is implemented, whichever sector of the AEC industry you work in, and then develop a plan to get to that place in the most efficient way possible.

How Does BIM Change Your Project Processes and Where Does Revit Fit In?

6 Apr , 2011  

As I’ve stated before, BIM is a paradigm shift from the way we’ve worked before.  That goes for whether you’re in the architecture, engineering or construction industry.  We’re not swapping out one software application for another.  I’m not even sure there’s a “one to one” swapping of 95% of the traditional (usually CAD) project process for the new (BIM) project process.  That being said, a destructive approach (i.e. wiping out the entire project process and starting from scratch) is neither realistic nor feasible.  So, if we can’t swap out 95% of our current project process, and we can’t wipe out our current project process all together, what do we do?  The answer is, targeted changes to specific parts of the current project process.  Here are some examples of areas that will change:

  • The project phases of a traditional project on the architecture side of things are schematic design, design development, construction documentation and construction administration.  Additionally, these phases generally last for the same lengths of time.  When a project uses BIM, phases can be consolidated into design, documentation and bid/build.  The design phase lasts longer while the documentation phase is shorter.  It’s worth mentioning, however, that the design phase does include conceptual design, schematic design and design development.  The point, though, is that design becomes more important to the project process than documentation.
  • In the construction industry, estimates tend to be manual.  Finishes, door hardware, and windows, for example, all tend to be manually counted, measured and quantified using a spreadsheet (i.e. Excel).  There is no link back to the design or the construction documents.  Changes made to the design need to be filtered through to the CDs to the estimates.  When costs are found to be too expensive in an estimate, that needs to be communicated back, considered in the design (which in turn gets updated in the CDs and on and on…).  With a project done in BIM, there is a conversation being continually had by all parties (technologically, or model to model, not verbally).  Therefore, estimates are derived directly from the model.  The oft used phrase is, a change anywhere is a change everywhere.  This is exactly what makes the BIM process more efficient.

As I write this, and think about it, we really are applying a destructive process, it’s just hard to see it because it takes a long time.  If there are 10 steps to your traditional project process, a year from now those steps might be unrecognizable.  The point is, an analysis of your current project process will allow you, and your BIM Advisor, to see what the most essential, immediate and easily changeable steps of your project process are.  After that, you can devise a plan on how to integrate them.

I’ve also been saying a lot that BIM is not Revit, and that Revit is just one piece of software under the BIM umbrella.  Your question to me, then, should be, How and where does Revit fit in? Revit starts and facilitates the project process.  Revit is where design and documentation initially happens.  It is where your building information model is born.  As the design and documentation phases proceed, it is where your building information model grows.  But, (ignoring home schooling) just like children, they cannot learn, adapt and mature only within your home.  They need to explore, and be explored, in other applications to see how it reacts to other models (i.e. MEP or structure), how it effects, and is effected by, the environment.  Once these lessons are learned, the information gathered, can be applied back to the model in Revit, in the form of design changes (I didn’t want to take the children metaphor further because it would be something like the child comes back and lives with his parents).  Eventually, the model can, although doesn’t have to, leave the Revit realm as it’s given to the builders who might want to run it through cost estimation and construction scheduling applications.  The point is, Revit acts as, more or less, the main software application within the BIM process.
