The New BIM Population

You might have noticed them, invading your user groups, listening intently at every event, asking different questions, and then they introduce themselves… Facilities groups. Owner representatives with increasing expectations and a pressing need to leverage technology. Sound familiar? Well it should. Facilities use of BIM is a decade behind the AEC industry and long term owners are now becoming aware of BIM and asking for it. Are you ready?

These are usually organizations in flux, expanding or under corporate mandate for a massive technology shift. They find themselves needing to assert themselves where they haven't before, without clear direction as to the ramifications of what they are asking for. 

Usually facilities groups are educated in BIM when new construction projects are in the design/documentation/construction process. Attending a BIM coordination meeting , they see the value of the model and they are hooked. What they miss is all the steps it took to get there. The mechanics of collaboration seem straightforward, just put the models together, coordinate, and build better buildings.

This situation turns the architect/engineer/contractor into a BIM educator when the stakes are high. Oversell and the expanded scope eats your margin up. Undersell and you risk seeming unsophisticated in BIM and losing future work. The right balance of education and added value for you and your clients could spell tangible success. Success that you can both wear proudly, success that shepherds your firm into the next decade of model integration.

Is Navisworks It?

Right now the interest that we are seeing in Navisworks has expanded exponentially. I attribute this to a handful of reasons. The Autodesk's Suites have increased the overall reach of Navisworks by putting licenses in the hands of Revit users at a fraction of the cost compared with purchasing completely separate packages of software.  Navisworks represents an extremely important platform for a BIM. We can now rely on the strengths of Navisworks as a near universal model aggregation tool, including integration of DWF or DWG sheet files. Navisworks can truly hold all 2D and 3D intelligent information and even "connect the dots" digitally between the different file formats of the same project. There is also several tiers of Navisworks that allow for the users that need to run and track clashes to have access to a deeper version of the software, and those that need to view and markup a free tool to do only that.

Get it? The Clash

Most new users want to use the Clash Detection tools inside of Navisworks Manage to collaborate digitally prior to construction. This, above all other functions, is the most valued of Navisworks and only available in the Manage version.  The Timeliner tool is a distant second in unique functions although, considering the improvements in 2013, it has the ability to pick up many construction simulation modelers looking to more seamlessly integrate data and geometry inside one comprehensive tool.  Plus, there are more applications that can tap the data into other formats (e.g. e-SPECS for Navisworks) for many different uses of the model. 

The backbone of the solution is the bevvy  of formats that read well into Navisworks. Keep in mind: geometry fidelity and the quality, organization and consistency of data inside of the geometry can make the difference between a easy integration or a process that is much more manual. Simply put, it all depends on what you put in and what you are asking it to do. Just because you can doesn't necessarily mean it is worthwhile to do. Pick your battles. There are also security features to Navisworks files that protect intellectual property and can serve as reliable record copies.

The simple tools for complex projects  that Navisworks packs, as well as the increased saturation in the AEC market, creates a real need in the industry to know the simple strategies to get the most out of the tool. This usually comes in the form of simple tips and ideas around setting up an iterative approach and generally getting your ducks in a row for digital coordination.

The point is Navisworks has the potential to be the platform for model aggregation for BIMs of all shapes and sizes, from all different locations. It has both a free solution, it has a comprehensive solution. 2D, 3D, 4D, 5D. Seriously. I remember the first time I told people that I work in software that goes to the 5th dimension they looked at me like I was an idiot. And while it is an overly clever way to say "time and data" on top of the 3D, it is true.  I would prepare for Navisworks to become a fixture in the digital design, construction, and facilities management practices for the foreseeable future.

BIM-washing

Conversations about BIM are funny. Even firms we are there to help can come across a guarded about heir BIM process and experience. I used to think it was a distrust I was sensing, after some contemplation and a lot more experience I believe it has much more to do with trying to manage a perception of BIM experience in an industry that is supposed to be inundated with it. I can tell you that mostly the industry is not inundated. There are very progressive groups and very  intelligent/experienced people, but a vast number of firms are posing as BIM savvy or even worse "fully BIM Implemented". Actually now that I think of it I'm not sure which is worse.

I cannot tell you what damage that does to the industry as a whole. In fact it makes it almost impossible to manage expectation and turns a provable credential into a magic show of smoke and mirrors. Even those that really seek to maximize their BIM benefit are forced to exaggerate the ease of BIM and downstream benefit.
 

Unfortunately I don't have the easy button about this one, its just a problem. Around the Dallas IMAGINiT office, we use the term "BIM-washing". The "yeah, yeah, we do BIM" that so many firms respond with when pressed. These are usually the statements of leaders/executives in a firm who have in the past purposely distanced themselves from the trenches of software technology integration. This is a GC and Architect problem mainly, it is much harder for Structural, and MEPF to hide this skill gap when they enter into a contract.

This is an oldie, but it fits so well. Hilarious part is that this character's name is Tommy Flanagan (I'll be quick to point out it is a different spelling and pronunciation, hilarious though).

Those firms over promise, under deliver, and in many cases under bid when the modeling scope expands but they don't know any better. Generally they bring us all down. Now I know I'm preaching to the choir a little here, or a lot. But maybe it is time to force the hand of every firm to put their experience out there. Maybe its time to stop selling BIM to owners and start educating owners about practicality and honest benefit without expanding the scope 5-fold. I'm just riffing here but this is a major frustration of mine. When "it" hits the fan we are the guys they call. It usually goes like this: "Hey, I won some BIM work, so I need BIM. The project starts in a week, when can I get in a class? The class comes with the software right?" In a sales environment this seems like a perfect situation but it is not. They put us in the same  somewhat impossible situation that they have stumbled their way into.  It isn't a switch you flip, there are many caveats many things to understand, many things to discover for yourself. It takes time. Even if you hired us to come to your office every single day, or hired 1 or 2 experienced people full time, it just isn't that easy. Ok well now I'm just venting.

Let's stop BIM-washing together. Help me figure out how. Help yourself. Help the industry.

What Do I Mean By Model Integration?

I wanted to take a post to explain a commonly used term that carries a lot of importance as software tools improve and interoperability increases, model integration. Model integration is the ability to take a single model and use it for design, analysis, documentation, virtual construction and finally facilities management. Each of these will be explored further in future posts but let's start by taking a look at the opportunity and challenges we face in this effort.
 

It is completely irresponsible of me to tell you that this is, top to bottom, entirely possible and incredibly easy. At the very least it takes a very pointed LOD document and a fair amount of model repurposing. In addition to that it might take a good deal more scope, so be prepared when the client asks for a model they can use in FM, it might mean a whole lot more modeling and data integration. There's that word again, integration.

Now let's take a look at what I consider to be the major hurdles to model integration:

Willingness to Share Models - This was a bigger problem 2-3 years ago, but the fact that sharing a Revit model means all of your content goes with it make people understandably nervous.

Consistent Modeling - If you don't know what fidelity of model you are getting how could you reliably use it? Many in the industry have taken the dive into the LOD document, but how do we make that more than just an addendum to a contract? How do we bring that into the modeling habits of the ever day user?

Entrenched Belief - In such a quickly changing industry is it impossible to assume the quality of the model you get today is the quality of the model you get tomorrow. Don't make rules that are hard to turn back on. Several years ago a General Contractor would scoff at the idea of using a designers model. The most progressive of that group would simply reply "I'll model it myself".  Now when we show contractors the easily leverage-able elements in a Revit model most can't believe what they are seeing. It won't replace every manual effort, but certainly some if not most.

Limitations of File Formats and Software Capabilities - This one mainly has to do with solutions being over sold on their "automatic capabilities". Software is software, I am not trying to change the software, I am looking to saddle it and take it for the most beneficial ride I can. Great strides have been made recently to make models more friendly to construction modeling repurposing and more is coming on integrating structural and building performance analysis. I get stuck in the "It's 2012! Why can't t do that yet." But that doesn't matter in the end. Keep in mind this is a stagnant technology, today's issues are tomorrow's new functionality. The sky is he limit.

I hope to explore more detail model integration process and issues for each of the 5 types of models during the course of this blog. Stay tuned.

Owner Standards

One thing that I can say is lighting the fire of change across the industry is the owner BIM guideline. If you haven't been able to pour through one of these documents I highly suggest you do especially before bidding on one of these projects. It can drastically change your scope of work and if you are not aware of that impact you run the risk of losing you shirt on these projects. In my opinion these guidelines have the potential to make AEC firms more profitable by increasing the workload/fees, and therefore the value of a delivered model. Message: Don't fear the guideline, saddle it and take it for a spin.
 

Here are a few examples of these owner guidelines for your reading pleasure. These are in no way meant to represent the full range of owner BIM Guidelines.
