What is Building Information Modeling(BIM)

• BIM modeling can be used by anyone in the AEC
  Industry. It is the future of the sector. It has
  been seen that 3D BIM models of 3D buildings have
  been highly reliable by both large and small
  companies in recent years.
• BIM (Building Information Modeling) is an
  intelligent technology tool that creates three-
  dimensional models of buildings for different
  purposes. It is a powerful visualization tool
  that can be used to dominate projects wherever it
  is used. BIM is a common tool used by engineers,
  contractors, project owners, and architects.
• Building information modeling has many
  advantages that make it so popular. This tool
  has revolutionized the way the industry operates.
  As it adds additional details to the table,
  every user can count on its three-dimensional
  aspect. These details make the project more
  level. Once stakeholders have a BIM model for
  their project, theres no going back. Its a
  great tool that provides users with a lot of
  conveniences.

How LOD does help in detailed BIM modeling?

• The BIM models are extremely detailed and ensure
  that geometric elements remain in place. This
  information makes the process more efficient in
  terms of accuracy and quality. This allows
  professionals to trust the information to a
  certain level.
• BIM modeling is a systematic process that ensures
  success. It optimizes the regulation of the
  process toward an efficient output.
• The LOD allows the designers to understand the
  features and integrate them into the various
  phases of the project. This gives you a better
  understanding of the model being built. This
  allows for better execution and result of the BIM
  project.

The origin of the LOD concept?

• LOD is a term that was initiated by AIA, i.e. the
  American Institute of Architects. 2008 was the
  year of the instigation. Five levels of detail
  were then introduced to provide the detailing
  stage for any 3D BIM model.
• Although AIA is the one who deserves credit for
  the term, the original concept was there. Revit
  software, which is software for building
  analysis, has used a similar approach to
  calculate project costs. They found certain
  stages in their design process to be most
  useful. Although this concept has evolved over
  time and now has six levels, it was created in
  2000.

Different Levels of Detail (LOD)
LOD 100 (Concept Design)
This is the first stage of a building project. It
shows the model from the simplest possible
perspective with very little information. Models
are represented using either symbolic or
graphical connotations. The models detail
defines the size, area, heights, orientation,
volume, and so forth. This model generally uses
approximate terms.

Different Levels of Detail (LOD)
LOD 200 (Schematic Design)
The second stage of detail consists of details
about the materials and their quantities of
them. This stage shows the model in its entirety.
The different modeling characteristics are
displayed according to their exact shapes, sizes,
locations, and orientations. This stage also
includes non-geometric and non-graphical
information. Even though this stage is
approximate, it can be used.

Different Levels of Detail (LOD)
LOD 300 (Detailed Design)
All measurements and information related to the
model are now presented in a more precise form.
The models characteristics are presented in a
more detailed manner. The model provides precise
details about the dimensions, shape, quantity,
position, orientation, and size. Based on the
requirements of raw materials and other
resources, the details are calculated. The
elements and the definition of the project are
given here.

Different Levels of Detail (LOD)
LOD 350 (Construction Documentation)
The actual construction can begin once the
foundation has been built. This stage is where
clash detection takes place. Clashes are
immediately rectified. A connection is made
between the various construction elements and
other buildings. These characteristics are not
graphical.

Different Levels of Detail (LOD)
LOD 400 (Fabrication Assembly)
This is a crucial stage of the modeling process.
This stage is where the fine details of the
model are added for final execution. This stage
includes all details of the project.

Different Levels of Detail (LOD)
LOD 500 (As-Built)
This stage incorporates the final graphical
elements into the finished project. This stage
shows all changes and deviations to the original
design. This final model serves as a reference
point for all future operational activities
related to building construction. It will be
there throughout the projects life cycle.

Conclusion

• BIM intelligence is based on the inclusion of the
  Level of Detail (LOD), in its modeling process.
  It makes the model more accessible without
  compromising its fundamental details. It allows
  professionals to have more information about the
  construction process and maintains
  communication. The LOD also accurately sets the
  graphical outcome so that the final model does
  not suffer from any errors. The various stages
  ensure that each stage is given enough attention
  and work is done productively. Designers and
  other professionals can attest to the high
  productivity LOD brings to the workplace.
