‘What is BIM?’ – is probably the most
off-putting intro question to anyone listening to a BIM presentation that a
speaker can pull up, yet it comes up time after time at BIM conferences and
lectures.
In a way, I understand why that is –
audiences generally vary in their understanding of BIM to such extent, that speakers
feel obliged to always start from the beginning.
And then, there is another troubling
issue about the question – the answer is actually NOT that obvious, and it
varies from application to application.
For example, while almost everyone
publicly agrees that no-one software (not even Revit) equals BIM – all sorts of
other descriptions are likely to float around, from simple ‘one word’ depiction
to highly complicated bullet-pointed explanations.
I used to like the word ‘approach’
for it, being a ‘language’, ‘a set of tools and processes’.
These days, if pushed, I say that BIM
is merely a combination of a specific set of ‘Attitude and Commitment’ which
leaves people usually dumbfounded and me alone.
Regardless of its name (I know, the
acronym has been only around since Autodesk had invented it) or what it means
for people, there are reliable ways on measuring its effectiveness and
‘maturity’ in the current day BIM market.
Still, while numbers should always
reflect real pictures, statistics and surveys generally are a bit flawed and
subjective, leaning to the expectation of their compilers.
So, those that claim BIM to be in a
pretty good shape and maturing according to preset programs across the board,
are likely to have some vested interest in making it look better than it really
is.
Others, like me, that state, that the
real impact (positive) on the global AEC made by the last 2 decades of BIM-push
has been negligible are, also most likely blinded by their disillusionment due
to the failure of their own endeavors.
Nevertheless, I stay firm behind
the statement, that regardless of the good work of many people, honest
intentions and lots of money, BIM had made not much more than a little dent in
the ineffectiveness, sluggishness and generally archaic ways that the global
AEC is run.
Worse even from that fact, it did
little to improve the processes (don’t believe me, go to weekly meetings of
medium to large projects), it had done almost nothing to increase
accountability and decrease corrupt practices that plague the industry.
Yes, people create BIM bunkers, walk
around with lasers, VR headsets and iphone models, but these are few and far
between, are often just a gimmick, and most definitely operate below the magic
line of real decision (and money) makers of the industry.
If I publicly ask for anyone to name
a Project Director of a largish project with BIM competency, I am sure people
will throw lots of names in the basket, but my experience (on lots of large and
very large projects) is that there are NO Project Directors, Commercial
Managers, Lead Planners, Control Managers, Project Managers that can be trusted
with anything even close to ‘real BIM’ (or very, very few).
Sure, many will happily ‘chew the
fat’ on the topic, but all their experience would be second hand, through
others doing it for them.
Going back to the title, I seem to
remember that 20+ years ago, when I started on BIM (that still had no name for
it) it was much more fun to be involved with the movement.
Skeptics will say, that was no BIM,
just 3D, but the fact is that I used 3D for documenting full buildings from the
first day I learned ArchiCAD (4.5), applied appropriate materials (meta data!)
– and jumped on the first opportunity of doing 4D models when I came across,
the then extremely buggy and highly temperamental Construction Simulation. Furthermore,
persisted using it for years, in spite of a scary number of failed movie making
attempts and sleepless nights.
I also recall, that the BIM people of
that era were approaching ‘issues’ with more criticality than the somewhat
blind enthusiasm and misguided loyalty (to various parties) of those
now in charge do.
I hate to say (but must), the average
IQ of BIMmers seemed to be a notch or two higher as well, even though the
numbers involved may have been quite a bit lower, than now.
Internet was in its very early stage
and emails still clunky, but the ArchiCAD worldwide support group moderated by
Djordje Grujic was legendary.
You could put up questions at night
New Zealand time and have numerous answers by real (not just self-styled) gurus
next morning.
Sure, it was not all sunshine,
lollipops and rainbows – the industry shunned us, happy to hire AutoCAD
seamstresses by the dozens instead, many typing faster in lisp than talking in
their own mother tongues, rather than even consider anything more than flatCAD.
CAD managers taunted us for file
sizes and line types and fonts and RAM.
We were the weirdoes of the time, but
we still felt we were the future.
I did, anyway.
Nowadays, I see no future for BIM,
the way it is being pushed by flaky mandates, super-large companies ‘polished
up global BIM policies’ and across the board reluctance to accept any
criticism, reality checks or change of courses set by ‘standard makers’.
I say, I see no future for current
BIM. But I do see future for something else helping the industry and maybe,
just maybe able to bring the spark of the ‘early BIM times’ back to the oldies
and the new wizzes of the industry.
I will explain it all at a
presentation I will be holding on the 30th October 2017 at the Canadian University in Dubai.
Still working on a possible webcast,
but if that does not happen, there will be a youtube video for those unable to
come, but interested.
