Do The Graphic
Level Of Detail Of
Bim Elements And
Level Of Detail Of
Data Have To
Match?
The answer to this question may
be a conditional yes.
Namely, in practice, I often
encountered different requirements
in terms of the LOD of BIM
elements which were not strictly
following the typical requirements
of the project phase ie.
according to the brief overview
given in the previous chapter of
the article - comparing the BIM
element level of detail from LOD
100 to LOD 500.
To tickle your imagination, I am
going to give you a typical
example that completely deviates
from the schedule view of the
LOD 500 of BIM elements during
the various phases of the project.
Take elevator geometry and
elevator data, for example. In the
FM model and the digital twin
model of a constructed building,
for example, the elevator can be
presented geometrically as a
simple prism, while in terms of
parameters and data it must be
presented in much more detail.
Elevator data in the FM model
and digital twin model must
provide information about who
the elevator manufacturer is,
what material the elevator was
made of in the BIM model, when
the previous elevator service was,
when the next elevator service is,
how many people can fit in the
elevator, cable data and other
details related to elevator
lifecycle monitoring, etc.
After this very simple example
regarding the LOD requirements
of the BIM element related to the
elevator in the FM phase of the
project or the digital twin model, I
think it is clear to you why I
initially answered the question as
a conditional yes.
In this regard, I hope you
understand that LOD 200 or LOD
300 is sufficient for the graphic
requirements of the elevator,
while the LOD 500 is required for
parameters and data for the FM
model or the digital twin model
to fulfill all requirements for an
adequate LOD of the BIM
elements.
How To Verify The
Implementation Of
Bim Element Lod?
The most logical answer to this
question is that the investor
should verify that all
requirements related to the LOD
of BIM elements in the BIM
project process have been met.
The simplest way for an investor
to do this is to hire an experienced
BIM Manager or BIM Consultant,
who would check, in the interest
of the investor, the degree of
implementation of the BIM
element LOD in the BIM discipline
models.
To avoid any complications and
to identify any shortcomings in
the BIM discipline models on
time, it is best to organize
periodic virtual multidisciplinary
BIM meetings, where a mutual
review of all BIM discipline
models is conducted.
Such a process would prevent
any problems in reaching the
required LOD of BIM elements in
the BIM model of any discipline
and would give sufficient time to
all project participants to remedy
any deficiencies if they were
noticed at any time during the
BIM project process.
