elements during and at the end
of each project phase.
All of the above leads us to the
logical conclusion that the levels
of detail of the BIM elements
change at each project phase
during the project life cycle.
One has to be very careful about
the required level of detail of BIM
elements during each project
phase, primarily for coordinated
exchange of BIM data during the
BIM project process and then for
financial reasons, since all
participants in the project
process should be aware of the
fact that the higher requirement
in terms of the level of detail of
BIM elements at some phase of
the project, the higher work, and
therefore the higher cost of
generating BIM geometry and
data in the BIM discipline model.
After defining exactly what the
LOD or the level of detail of BIM
elements means and explaining
in principle the relationship
between the level of detail of BIM
elements and project phases,
logical questions arise:
of data have to match?
• How to verify the
implementation of BIM element
LOD?
• Is the chapter on the LOD of the
BIM elements sufficient to ensure
efficient coordination of the BIM
model and the exchange of data
from all participants in the BIM
project process?
Below, I will give you a detailed
answer and explanation for each
question asked.
Who Defines The
Level Of Detail Of
Bim Elements?
Bearing in mind that the interests
of the designer, contractor and
investor do not completely
coincide during the BIM project
process, I do not think it is
possible to give a simple answer
to the question which party in the
project process needs to define
precisely the level of detail of the
BIM elements.
First, it should also be borne in
mind that the BEP chapter, which
deals with the level of detail of
BIM elements, most commonly
defines the graphical layout of
BIM elements and the data
assigned to those elements in
BIM discipline models. Indirectly,
the BIM element LOD also affects
the multidisciplinary BIM
workflow and data sharing in a
multidisciplinary BIM
environment by placing clear
requirements on the BIM
element LOD in front of the
disciplines designers, both
graphically and in terms of data
that the BIM discipline model
should include.
All this provides a framework for
discipline designers to exchange
information efficiently from the
BIM discipline model, and it is
therefore very valuable to set the
level of detail of the BIM
elements to the discipline
designers, which would allow
them to exchange data as
efficiently as possible within the
BIM project process during a
particular project phase.
Considering all the above in the
article section on who defines the
level of detail of BIM elements, I
think it is most logical that the
investor is a participant in the
project whose interest is to
manage the LOD requirements of
BIM elements for each discipline
in the BIM project process.
• Who defines the level of detail
of BIM elements?
• How to define the level of detail
of BIM elements depending on
the project phases?
• Do the graphic level of detail of
BIM elements and level of detail
