buildingSMART (get over it)
Mario Guttman, AIA
Vice-president and Firmwide CAD Director
HOK
What is
"buildingSMART"?
That's "building"
as a verb. And, "smart," as opposed to "dumb."
It's similar
to "building green."
It's about the
Building Industry using computers, and new ways of working, to be
more efficient and create a better built environment.
Forget about
"Interoperability" and "Industry Foundation Classes"
and all that stuff. Most people can't even say those things, much
less understand them.
Instead, let's
talk about making design decisions earlier.
Let's talk about
controlling construction costs; and, using less energy.
Let's talk about
better design; and pre-fabrication with mass customization.
I don't need
an exact definition for "buildingSMART;"
I know it when I see it. Let's get on with it.
Why Do We
Have to "Get Over It"?
Because our
whole industrydesigners, builders, owners, operators, academics,
software developersis doing it now. It is here. It is real.
As individuals,
we can lead, follow, or get out of the way.
As a firm, HOK
chooses to lead. I have been directed to take the word "try"
out of my vocabulary. I don't have the time or patience for surveys
or CAD "bake-offs."
What I am doing
is showing Revit to our project teams and asking them, "Do
you want to work this way?"
"Well,
duh!"
Getting
Back to Doing Architecture Again
For two decades
we have forced design professionals to know about the "DIMWIT"
and "DUMBASS" variables and it has hurt their ability
to put buildings together. Even worse, our most knowledgeable practitioners
are no longer able to "grab the pencil" and teach the
next generation.
Computers are
changing the way we work; let's make sure that they are making it
better. We don't need a "paradigm shift." We simply need
to regain control of the design process in those areas where we
have historically added the most value.
I foresee that
with Revit, our project teams will be smaller and more capable.
I don't think we can continue to include pure CAD drafters or CAD-illiterate
design professionals. I think we will all be better design professionals
as a result.
Sorting
Out Autodesk Architectural Desktop and Revit
Read my lips:
"We do not want to have two CAD solutions."
HOK is no slouch
when it comes to using Architectural Desktop (ADT). Our honorable
mention in the AIA's Technology in Practice BIM Awards (see AECbytes
Newsletter #21) was for an information model that includes 2.4-million
square-feet of hospital space and tracks 300,000 items of medical
equipment in 10,000 rooms.
Between our
very smart CAD users and some judicious custom programming, we can
model anything in ADT. The fundamental strength of its object model,
and the inherent flexibility of the file structure, are second to
none, including Revit.
But ADT is a
bear to implement.
Sit down at
home with ADT on a Saturday morning and try to figure out the display
system. By 3-o'clock you will be really angry that you have been
put in the position of trying to explain this stuff to your users.
Next week, sit
down with Revit. You will come away saying, "Hey, this really
makes sense." It's not that it is so sophisticated; it is that
it is so obvious.
We are doing
over twenty Revit projects this year. I believe that next year they
will all be Revit.
BIM is Your
Friend
The danger in
all of this is that the proponents of Building Information Modeling
(BIM) have been a bit arrogant in their dismissal of CAD with phrases
like "just an automated pencil" or "dumb, 2D drawings."
It is bad enough
that this is alienating the people doing that work. More significantly,
it has created the expectation that BIM is somehow superior, or
at least very different. This has resulted in unreasonable expectations,
and ultimately frustration. I find myself bucking a certain amount
of misguided attitude about "having to model everything in
3D" and answering questions like, "Why hasn't BIM taken
off?""
My response
is that we have been doing BIM all along and it is better to recapture
that fact than to get distracted by the new toys. After all, those
of us who did hand drafting were creating abstract "models,"
containing hyper-linked, object-based "information," before
there was a computer industry.
Those "dumb"
drawings were a very efficient way of representing the "building
model" and defined just as much "3D information"
as the most advanced computer-based representation. What has changed
is that the modern CAD programs allow us to maintain a much higher
level of data integrity and are much better at illustrating the
consequences of our decisions. These new tools are not fundamentally
different, but they are vastly more capable.
As we change
our culture, users are much more interested in how Revit creates
a "coordinated document set" than about the "life-cycle"
value of smart documents. The consultants, contractors, facility
managers, and others that we work with, have always gotten a lot
of good information out of the work we produce; and I'm sure they
will get even more value as we organize and structure it more effectively.
But that is their business; we'll concentrate on doing ours better.
Some Things
I Don't Worry About
Usually, at
about this point, somebody asks me about two big concerns: Who is
going to pay for the BIM model? And, are we assuming more liability
in a BIM?
To be fair,
I have the luxury of knowing that someone else at HOK is taking
care of these issues. Nevertheless, I think they are misleading
in what they imply about our core values.
To begin with,
our primary mission is not to collect fees; it is to provide value
to our clients. We have always done this well and we are confident
that BIM technology will provide better value. There is no principle
more fundamental to HOK, and there is no need to make the discussion
more complicated than that.
Likewise, the
focus on liability is really a diversion from the more significant
issue of managing risk. Bad things happen in construction and our
goal as an industry is to distribute responsibility and compensation
appropriately. BIM provides a way to work as a team, with the other
members of our industry, and reduce risk with detailed, coordinated
documents.
Things That
I Do Worry About
I do have some
new worries.
To begin with, the BIM discussion has created a misconception that
exchanging information is something like gathering
nuts, where the bigger the bag we can toss over
the fence at the end of the day, the better. In
fact, controlling the flow of information is a
very important reason for the traditional divisions
of professional responsibility. My responsibility
as an Architect requires that I be very careful
in how I provide information and how it is used
by others. Accuracy and control are far more important
than quantity in information management, and I
am not convinced that everyone drinking the BIM
Cool-Aid gets this.
I am also concerned
that the building industry has probably surrendered more control
of its processes to the software industry than we ever intended.
However good the intentions of the software vendors, they are ultimately
driven to maintain their stock value; and, as a result, we are engaged
in a continuous juggernaut of upgrades that are not necessarily
improvements. HOK has structured its CAD strategy around the Autodesk
product suite but there are limits to this commitment. (In other
words, we may be living together, but the Charles Mingus Big Band
album is mine.)
The IAI
These concerns
are at the heart of HOK's commitment to the International Alliance
for Interoperability (IAI). We see this organization as the best
forum for developing rigor in how our industry exchanges information,
and insuring that this process truly serves all of our interests.
The IAI coined
the term buildingSMART when it realized
that its name wasn't very marketable. But the two are not synonymous.
Feel free to add your logo to the movement. Like this:

I think that
the IAI will ultimately be more significant as a shepherd to the
quality of our information exchanges than as a developer of the
technical details that have been its historical focus. With this
goal in mind, I hope that more of our colleagues in the building
and software industries will become actively involved in buildingSMART.
What Now
We are all fortunate
to be participants in the reshaping of our industry. Personally,
I am also fortunate to have made many friends in the AECO technology
business over the years. I hope they are having as much fun as I
am.
I also hope
that my profession, Architecture, will grow to recognize
how important these leaders of technology are to its future. I look
forward to the day when our CAD masters and IT heroes get to sweep
in with their very own black capes and take a place at the podium.
