each discipline designer and the
BIM Manager himself will add the
cost of too frequent
multidisciplinary BIM
coordination meetings to the
project price. Also, there is no
significant progress in project
terms at VDR, especially in the
early project stages to benefit
from frequent VDR on a weekly
basis.
Therefore, it is common practice
to organize VDR every two to
three weeks and as the project
progresses to the next phases,
VDR becomes more frequent.
Since the frequency of VDRs is
most often the responsibility of
BIM Manager and each project is
a story for itself, I would not give
me the freedom to give a strict
recommendation on the
frequency of VDRs, but would
leave the decision to the BIM
Manager or BIM Consultant.
By Optimizing BIM
Elements LOD, The
Investor Achieves
Big Savings
This conclusion does not require
much explanation. If you read the
article "What Is LOD - The Level
Of Detail Of BIM Elements?", I
believe you could easily conclude
that, the higher the LOD of BIM
elements, the more demanding it
is, both from the BIM modeling
perspective and from the
perspective of generating data
and information related to BIM
elements, so we come to the very
simple conclusion that the more
demanding the LOD of BIM
elements, the model
development will require more
resources, and this will result in a
more expensive BIM model for
the investor.
Very often, to explain this
conclusion, I take the BIM
element - the elevator car as an
example. Let's look at the BIM
model of the elevator car in the
BIM context and what you need
to know about it. It is good to
know the dimensions of the
elevator car, for the FM model
and for the digital twin model it is
good to know the basic geometric
information, but also information
related to regular and
extraordinary elevator servicing. I
consider all additional
information related to the
detailed geometry of the elevator
completely unnecessary because
apart from the visual effect, they
have no practical application
from a BIM perspective.
Let's ask ourselves why it is
necessary to go into the very
detailed geometry of the elevator
car when in the model it only has
the role of "information holder"
for service information? Okay, I
have to admit that it's nice to see
a perfect digital replica of an
elevator car, but someone has to
pay for it, the investor in this
case. Often in BIM models, we
find very detailed models of
certain BIM components. The
most common reason for this is
that they can be downloaded
from the websites of equipment
manufacturers completely free of
charge. If the perfectly modeled
elevator car reached the BIM
model in that way, it is quite okay
to see it in the BIM model,
because making such a digital
replica of the elevator car is not
expensive and is cost-effective for
both the designer and the
contractor, as well as the
investor.
I hope that after this short and
simple example of the elevator
car, you came to the conclusion
that it is not necessary to model
