BIM is a process, not just a technology, that involves 3D modeling of a building project from design through construction and facility management. It allows for improved coordination and communication between project stakeholders. Key benefits include easier identification and resolution of design issues, more accurate cost estimation, improved scheduling, and a detailed as-built model to facilitate facility management. Governments are starting to mandate BIM for large public construction projects to realize these benefits. HCSE Inc. is a structural engineering firm located in California that provides BIM services including 3D and 4D modeling.

2.  Most importantly, BIM is not a technology. It is a
process. This is possibly the most important
aspect to understand. BIM applies to all ​aspects
of the construction of a building, from the design,
the estimating, the supply chain, the delivery of
goods during the build, the build process, the
resource allocation, the productivity requirements
to meet targets and on in to the post-handover
phase through Facilities and Asset Management.​

3.  Aspects of BIM are enabled through various
technology platforms. There are several providers
of technology which supports architectural tools
plus the addition of intelligent information against
the model. Examples include Autodesk Revit​,
Graphisoft ArchiCAD 17, 12d Model and Synchro
Professional.

4.  BIM has several implementation levels:Level 0:
CAD using drawings, lines, arcs, text, etc.​
 Level 1: 2D & 3D using models, objects plus file based
collaboration
 Level 2: BIMs plus file based collaboration and library
management for models and objects and
 Level 3: iBIM, Lifestyle Management, common dictionaries,
data and processes underpinned by integrated and
interoperable data through web services

5.  Level 2 BIM is often seen as the minimum
standard to achieve. These levels are also split in
to A and B, e.g. 2A and 2B which denotes the
directionality of information sharing, i.e. one-way
or multi-way. Here are two diagrams explaining
the differences:

6.  Industry Foundation Classes (IFC) and COBie are standards used to
share information. ​IFCs describe building and construction industry
data. It is a platform neutral, open file format developed by building
SMART to facilitate interoperability in the architecture, engineering and
construction (AEC) industry. COBie is a data format for the publication
of a subset of building model information focused on delivering building
information and not geometric modelling. It is closely associated with
BIM and is typically exchanged using XML. These formats enable BIM
interoperability and all BIM software is able to consume this
information. Most are able to write it, enabling the sharing of
information, even at Level 2 BIM to be easily achieved. External
software such as Safe Software Feature Manipulation Engine (FME) is
able to transform from IFC and COBie to other formats. This represents
the beginnings of full integration possibilities between BIM and GIS.​​

7.  BIM is so much more than just a detailed 3D model of a building.
The concept is most easily explained by the term build 4
times which means build three times in the model and once on the
ground. The accuracy of the model combined with animations and
fly-throughs allow contractors to access the design layout before the
build takes place and make alterations. This means that when the
build takes place, there are fewer errors and far less rework
needed. This moves the construction procurement process from
design and build to design build by bringing the construction team
in to the design process rather than them simply having to respond
to a tender for construction after the design has been completed.

8.  Parametric Modelling is a key principle of BIM. Essentially this
means that everything in the model is connected to everything
else. If you move the location of a wall, the elements attached to
the wall also move. If you change the volume of a floor, the
quantities of material needed to lay the floor alter. If you move
ducting in the ceiling, all aspects associated with the ducting
update and conflicts are highlighted. This is also true for BIMs that
have been developed independently and brought together in a
collaborative BIM environment. This allows organisations who may
be controlling different elements of the build to benefit from one
another as aspects of the model are altered through the process.
Change once, benefit many times.

9. The 'D' elements of BIM relate to the
information associated with the model.
 4D relates to scheduling information; when will an element
be built. With this information you can enable just-in-time
(JIT) delivery of materials to site. This in turn has an impact
on transportation, making it more efficient, and reduces
storage issues as materials are delivered and immediately
installed.
 5D relates to the estimating and cost aspects of the building.
Each element within the building model has a cost associated
with it. This allows for detailed analysis to be done regarding
budgets. It also allows the delivery team to make accurate
predictions regarding how much needs to be done at any
given time in order to meet the construction targets.

10.  6D covers the sustainability targets for a building allowing
information such as energy use, sustainability from a
materials and management point of view to be understood
and Leadership in Energy and Environmental Design (LEED)
tracking to be performed.
 7D is the "as-built" BIM model which is important as part of
the handover process to the building owner. This model is a
fundamental part of the ROI for BIM as it provide accurate
Facilities Management (FM) and Asset Management (AM).
Each part within the building will have a lifespan and in the
event of replacement, the easy identification of parts ensures
that these processes may be performed efficiently.

11.  BIM enables new procurement processes to take place which
deliver certainty to all parties involved. A typical process might
look like this:
 The design and construction teams are selected
 The design work is done and is reviewed by the construction team and
other subject matter experts. This review identifies areas of rework.
 This process iterates 2 more times, the result is the best possible
design.
 Generic objects may have been used for materials and/or equipment;
these may now be replaced by specific models conforming to the IFC
classes with known materials, costs and supply chain information
associated with them. In this way, the full cost of the building, the
suppliers and supply chain costs of materials and the installation
methodology is known by everyone involved.
 The work can now start on site using the BIM to direct the build.
Technology assists in the build by presenting the BIM information in the
field as construction takes place. JIT delivery of materials keeps building
efficient.

12.  Governments around the world are now realising the benefits of
BIM, especially for large construction funded with public money,
and are beginning to mandate the use of BIM for these projects.
When has that ever happened for GIS? The effect of this is to
seed the industry to change. The reality is that the industry is
moving this way anyway as they have already recognised the
advantage of using BIM. The issue has been the slow adoption
of the client to realise the benefits of the BIM approach – to the
point that some are still rejecting the final as-built BIM model,
considering it an unnecessary cost rather than realising that it
will reduce the AM/FM costs of running the building. Given that
government is often the client, it would appear that this is
actually an internal issue between government agencies or even
roles with the same government agency that needs to be
resolved as quickly as possible.
