The reasons for this are many,
and I m going to list only the
most important:
• Better control over the process
of generating graphic
documentation and data in BIM
discipline models at each project
phase;
• Optimized transition to the
next phase of the project in the
BIM project process;
• Easier establishment of
automation of the BIM project
process, which results in the
absolute accuracy of the
generated data and more
efficient exchange of data
between different disciplines in
the BIM project process; more on
that topic, you can find in the
article „BIM Workflow
Automation“
• Reduction of design costs
through automation of the BIM
project process;
• By controlling and managing
the LOD requirements of BIM
elements, the investor gets a
cheaper BIM as built model,
which can serve as a very good
basis for the FM model and
digital twin model; read more in
the article "What Are The Digital
Twins?"
Following the reasons why an
investor should manage the LOD
requirements of BIM elements, it
is important to note that it is very
easy for an investor to achieve
the above goals by hiring a BIM
Manager or BIM Consultant, who
with his knowledge and experience
could bring significant
financial savings to the investor
through optimization of requirements
of the LOD of BIM
elements at all phases of the
project in order to establish the
most efficient BIM project
process.
How To Define The
Level Of Detail Of
Bim Elements Depending
On The
Project Phases?
Fortunately, the answer to this
question is not that complicated.
Specifically, the BIM project
process monitors the requirements
of each project phase, so
the direct relationship between
the LOD of the BIM elements and
each project phase is more than
obvious, with some exceptions.
I m going to try in a very simple
way to explain the requirements
of each LOD of BIM elements
during the project phases
through a very simple example -
the evolution of the door LOD
through the different phases of
the project:
After a very simplified way of
reviewing the requirements of
the LOD of the BIM elements
according to the project phases, I
think it would be useful to also
make a description of each level
of detail of the BIM elements -
LOD level:
• LOD 100:
• graphic requirements - the
most basic 3D geometry;
• parameters - the most basic
geometry without material data;
• LOD 200:
• graphic requirements – 3D
geometry;
• parameters - the most basic
data of elements materials;
• LOD 300/350:
• graphic requirements - 3D
geometry with details sufficient
for the preparation of tender
documents;
• parameters - information on
the materials of the elements
sufficient for the preparation of
the tender documentation;
• LOD 400:
• graphic requirements -
detailed 3D geometry with details
sufficient for the construction
state project;
• parameters - information on
the elements materials sufficient
for the construction state project;
• LOD 500:
• graphic requirements -
detailed 3D geometry with details
sufficient to produce the as built
project, FM model and digital
twin;
