BIM is a symptom of Building
Information Modeling, it is the
process of generating & managing
building data during it’s life cycle.
BIM uses three-dimensional, real-
time & dynamic building
modeling software to increase
productivity in design &
construction processes.
2
A foundational, intelligent model-based process for business
and industry transformation
Uses 3D models to
capture, explore,
and maintain
consistent and
coordinated
planning, design,
construction, and
operational data
Provides greater
project insight for
cost, schedule, and
constructability
Uses and shares
the same consistent
data whether you’re
at your desk or in
the field
Enables prompt
response to change
with processes that
are smarter and
faster

“CAD helps people to draw. BIM helps people to construct.”
(Richard Saxon, Ecobuild, February 2009)
CAD is a tool that is used instead of paper & pencil that are used
for documentation while BIM is a chain of processes from
Schematic Design till the construction facility management &
Documentation become just a phase helps to get the final output
of the project.

1 BIM
Managed CAD, with the increasing
introduction of spatial coordination,
standardised structures and
formats as it moves towards Level
2 BIM
Level 2
BIM
Managed 3D environment with
data attached, but created in
separate discipline-based models
Level 3
BIM
A single collaborative, online,
project model with construction
sequencing (4D), cost (5D) and
project lifecycle information (6D).
This is sometimes referred to as
‘iBIM’ (integratedBIM)
15
LOD, as in "Level of Development", is a measure of how seriously you take the information
represented by a BIM element. It is not necessarily a measure of the amount of information, although
obviously there must be enough information to satisfy the LOD level. It is also not a measure of the
amount or accuracy of graphical information. The appearance of a BIM element is only one piece of
information about that object, and usually the least important. A contractor doesn't need to know what a
desk looks like to order it, nor to place it in the building. But they do need to know what the
manufacturer and model number is. Others may need to know its dimensions to coordinate with things
around it, but they too do not necessarily need to know what it exactly looks like.
Or in general terms:
LOD 100 = there is a thing
LOD 200 = there is a thing about this size
LOD 300 = there is a thing with these functions and options
LOD 400 = it is this particular thing.
LOD 500 = this particular thing provided by this person on this date.
16
LOD levels for a chair might go:
LOD 100 = there is a chair
LOD 200 = there is a chair that has
nominal space requirement of 500x500
LOD 300 = there is a chair with arm
rests and wheels
LOD 400 = manufacturer and model
number.
LOD 500 = manufacturer and model
number, supplier, date purchased.
17
LOD is sometimes interpreted as Level of Detail rather than Level of Development. This
Specification uses the concept of Levels of Development. There are important differences.
Level of Detail is essentially how much detail is included in the model element. Level of
Development is the degree to which the element’s geometry and attached information has
been thought through – the degree to which project team members may rely on the
information when using the model. In essence, Level of Detail can be thought of as input to
the element, while Level of Development is
reliable output.
18
Fully computable, reliable information
 no checking or re-keying of data
“The end-to-end stream of BIM data will help unify the
industry's supply chains, freeing construction from its
craft origins, transforming it into a modern,
sophisticated branch of the manufacturing industry.”
Ray Crotty (2011) The Impact of Building Information Modelling
19
“BIM Implementation will change the dynamics & behaviours of
the design-construction supply chain, unlocking new, more
efficient & collaborative ways of working.” (Francais Maude, Minister of state
for Trade and Investment)

Area
Conceptual design
Sustainable
building design
Create a building model and complete set of designs documents in an integrated
database, where everything is interconnected and there is real-time self-
coordination of information
Description Example
Quickly iterate on design
elements including building
form, sustainability, client
requests, municipal
regulations, budget, and more.
Conduct analyses and
simulation
The Beck Group created 100 visualizations for
a church in Seoul and adjusted the shape of the
building to appear curved, but with flat glass,
saving over $1 million on glazing and mullions,
and 1,000 hours of design time
Complete energy analysis
early in the design stage to
reduce ongoing energy
consumption
Using BIM to evaluate design scenarios for
energy savings, NASA’s 50,000’ building in
Silicon Valley yielded features such as a steel-
frame exoskeleton, geothermal wells, natural
ventilation, wastewater treatment, and a
photovoltaic roof that will provide 30% of the
building’s power

Area Description Example
General construction
Pre-fabrication,
modular construction
 Links project planning to
construction planning and
simulation, as well as visualization
during construction and digital
fabrication
 Enhances project communication
and collaboration among teams
 Create more accurate cost
estimates
 Deliver more projects on time and
within budget
Contractor Robins and Morton used BIM
to design and construct an Augusta,
Maine hospital. Due to greater
collaboration, the project was completed
ten months ahead of schedule and
returned approximately US$20 million in
value-added savings.
 Extract information from BIM to
pre-fabricate building components
to improve project schedule, reduce
cost, improve site safety, and
produce greener construction
practices by reducing material
waste
J.C. Cannistraro used BIM and pre-
fabrication to upgrade the central utility
plant for University of Massachusetts's
Boston campus helping to minimize
installation time of a new HVAC system
and hangers
23
Area Description Examples
Lifecycle costs  Reuse building models and data to
better manage facility operations
 Analyze data-rich models to
optimize resources and reduce
waste and lower lifetime
maintenance and operation costs
 Use intelligent 3D models to help
manage space and perform spatial
validation for tenant chargebacks
 Shanghai Tower Construction &
Development Co. Ltd. used BIM not only
to design and build, but also to inform
operations of their super high-rise tower.
STC&D plans to use BIM for emergency
and property management going
forward.
 The Government Services Administration
(GSA) is creating a database of its 3D
models to inform O&M and future
projects. Additional software leveraging
the 3D models will use its data for
security, updates, analysis, and reporting.

BIM, an acronym for 4D Building Information Modeling and a term widely used in the CAD industry, refers to the intelligent
linking of individual 3D CAD components or assemblies with time- or schedule-related information.
The use of the term 4D is intended to refer to the fourth dimension: time, i.e. 4D is 3D plus schedule (time).
The construction of the 4D models enables the various participants (from architects, designers, contractors to owners) of a
construction project, to visualize the entire duration of a series of events and display the progress of construction activities through
the lifetime of the project. This BIM-centric approach towards project management technique has a very high potential to improve
the project management and delivery of construction project, of any size or complexity.

BIM, an acronym for 5D Building Information Modeling, is a
term used in the CAD and construction industries, and refers to
the intelligent linking of individual 3D CAD components or
assemblies with schedule (time - 4D BIM) constraints and then
with cost-related information.
The creation of 5D models enables the various participants
(from architects, designers, contractors to owners) of a
construction project to visualize the progress of construction
activities and its related costs over time. This BIM-centric
project management technique has potential to improve
management and delivery of projects of any size or complexity.

BIM, an acronym for 6D Building Information Modeling and a term
widely used in the Construction industry, refers to the intelligent
linking of individual 3D CAD components or assemblies with all
aspects of project life-cycle management information.
The 6D model is usually delivered to the owner, when a construction
project is ready to be closed-out. The “As-Built” BIM model is
populated with all relevant building component information such as
product data and details, maintenance/operation manuals, cut
sheet specifications, photos, warranty data, web links to product
online sources, manufacturer information and contacts, etc. This
information-centric database is made globally accessible to the
users/owners through a customized proprietary secure web-based
environment. The accuracy of 6D BIM aids facilities managers in the
operation and maintenance of the facility throughout its life cycle.

"If you cut corners or put bad information in then
you’re going to get bad information + bad results
out"
Human Resources still the no. 1 factor of success.
It will take Time & Effort, and There are Risk
No, it Won’t
"As a process BIM is a great tool... but it takes the
skill + integrity of people to use that tool effectively
Steadily in time, with the right learning and the
right strategy, BIM can transform your business

Bim overview

  • 2. BIM is a symptom of Building Information Modeling, it is the process of generating & managing building data during it’s life cycle. BIM uses three-dimensional, real- time & dynamic building modeling software to increase productivity in design & construction processes. 2
  • 3. A foundational, intelligent model-based process for business and industry transformation Uses 3D models to capture, explore, and maintain consistent and coordinated planning, design, construction, and operational data Provides greater project insight for cost, schedule, and constructability Uses and shares the same consistent data whether you’re at your desk or in the field Enables prompt response to change with processes that are smarter and faster 3

  • 9. “CAD helps people to draw. BIM helps people to construct.” (Richard Saxon, Ecobuild, February 2009) CAD is a tool that is used instead of paper & pencil that are used for documentation while BIM is a chain of processes from Schematic Design till the construction facility management & Documentation become just a phase helps to get the final output of the project. 9

  • 15. Level 1 BIM Managed CAD, with the increasing introduction of spatial coordination, standardised structures and formats as it moves towards Level 2 BIM Level 2 BIM Managed 3D environment with data attached, but created in separate discipline-based models Level 3 BIM A single collaborative, online, project model with construction sequencing (4D), cost (5D) and project lifecycle information (6D). This is sometimes referred to as ‘iBIM’ (integratedBIM) 15
  • 16. LOD, as in "Level of Development", is a measure of how seriously you take the information represented by a BIM element. It is not necessarily a measure of the amount of information, although obviously there must be enough information to satisfy the LOD level. It is also not a measure of the amount or accuracy of graphical information. The appearance of a BIM element is only one piece of information about that object, and usually the least important. A contractor doesn't need to know what a desk looks like to order it, nor to place it in the building. But they do need to know what the manufacturer and model number is. Others may need to know its dimensions to coordinate with things around it, but they too do not necessarily need to know what it exactly looks like. Or in general terms: LOD 100 = there is a thing LOD 200 = there is a thing about this size LOD 300 = there is a thing with these functions and options LOD 400 = it is this particular thing. LOD 500 = this particular thing provided by this person on this date. 16
  • 17. LOD levels for a chair might go: LOD 100 = there is a chair LOD 200 = there is a chair that has nominal space requirement of 500x500 LOD 300 = there is a chair with arm rests and wheels LOD 400 = manufacturer and model number. LOD 500 = manufacturer and model number, supplier, date purchased. 17
  • 18. LOD is sometimes interpreted as Level of Detail rather than Level of Development. This Specification uses the concept of Levels of Development. There are important differences. Level of Detail is essentially how much detail is included in the model element. Level of Development is the degree to which the element’s geometry and attached information has been thought through – the degree to which project team members may rely on the information when using the model. In essence, Level of Detail can be thought of as input to the element, while Level of Development is reliable output. 18
  • 19. Fully computable, reliable information  no checking or re-keying of data “The end-to-end stream of BIM data will help unify the industry's supply chains, freeing construction from its craft origins, transforming it into a modern, sophisticated branch of the manufacturing industry.” Ray Crotty (2011) The Impact of Building Information Modelling 19
  • 20. “BIM Implementation will change the dynamics & behaviours of the design-construction supply chain, unlocking new, more efficient & collaborative ways of working.” (Francais Maude, Minister of state for Trade and Investment) 20
  • 22. Area Conceptual design Sustainable building design Create a building model and complete set of designs documents in an integrated database, where everything is interconnected and there is real-time self- coordination of information Description Example Quickly iterate on design elements including building form, sustainability, client requests, municipal regulations, budget, and more. Conduct analyses and simulation The Beck Group created 100 visualizations for a church in Seoul and adjusted the shape of the building to appear curved, but with flat glass, saving over $1 million on glazing and mullions, and 1,000 hours of design time Complete energy analysis early in the design stage to reduce ongoing energy consumption Using BIM to evaluate design scenarios for energy savings, NASA’s 50,000’ building in Silicon Valley yielded features such as a steel- frame exoskeleton, geothermal wells, natural ventilation, wastewater treatment, and a photovoltaic roof that will provide 30% of the building’s power Design Documentation 22
  • 23. Area Description Example General construction Pre-fabrication, modular construction  Links project planning to construction planning and simulation, as well as visualization during construction and digital fabrication  Enhances project communication and collaboration among teams  Create more accurate cost estimates  Deliver more projects on time and within budget Contractor Robins and Morton used BIM to design and construct an Augusta, Maine hospital. Due to greater collaboration, the project was completed ten months ahead of schedule and returned approximately US$20 million in value-added savings.  Extract information from BIM to pre-fabricate building components to improve project schedule, reduce cost, improve site safety, and produce greener construction practices by reducing material waste J.C. Cannistraro used BIM and pre- fabrication to upgrade the central utility plant for University of Massachusetts's Boston campus helping to minimize installation time of a new HVAC system and hangers 23
  • 24. Area Description Examples Lifecycle costs  Reuse building models and data to better manage facility operations  Analyze data-rich models to optimize resources and reduce waste and lower lifetime maintenance and operation costs  Use intelligent 3D models to help manage space and perform spatial validation for tenant chargebacks  Shanghai Tower Construction & Development Co. Ltd. used BIM not only to design and build, but also to inform operations of their super high-rise tower. STC&D plans to use BIM for emergency and property management going forward.  The Government Services Administration (GSA) is creating a database of its 3D models to inform O&M and future projects. Additional software leveraging the 3D models will use its data for security, updates, analysis, and reporting. 24

The use of the term 4D is intended to refer to the fourth dimension: time, i.e. 4D is 3D plus schedule (time). The construction of the 4D models enables the various participants (from architects, designers, contractors to owners) of a construction project, to visualize the entire duration of a series of events and display the progress of construction activities through the lifetime of the project. This BIM-centric approach towards project management technique has a very high potential to improve the project management and delivery of construction project, of any size or complexity. 6D Facility Management 3D plus analysis element Operation & Maintenance. 7D RFID Materials & Objects tracking 47

The 6D model is usually delivered to the owner, when a construction project is ready to be closed-out. The “As-Built” BIM model is populated with all relevant building component information such as product data and details, maintenance/operation manuals, cut sheet specifications, photos, warranty data, web links to product online sources, manufacturer information and contacts, etc. This information-centric database is made globally accessible to the users/owners through a customized proprietary secure web-based environment. The accuracy of 6D BIM aids facilities managers in the operation and maintenance of the facility throughout its life cycle. 53

  1. Building Information Modeling (BIM) is a process that begins with the creation of an intelligent 3D model to capture, explore, and maintain planning, design, construction, and operational data in order to better inform decision making for building and infrastructure projects. The information in the model remains coordinated and consistent an Create and use a data-rich 3D model to improve how buildings and infrastructure are planned, designed, built, and managed. Provides greater project insight on things like cost, schedule, and constructability Share and use the same consistent data whether you’re at your desk or in the field Respond quickly to change with processes that are smarter and faster Model is available for simulation, analysis, collaboration, and communication throughout the lifecycle of the project.

  3. Level 0 BIM In its simplest form, level 0 effectively means no collaboration. 2D CAD drafting only is utilized, mainly for Production Information (RIBA Plan of Work 2013 stage 4). Output and distribution is via paper or electronic prints, or a mixture of both. The majority of the industry is already well ahead of this now (source: NBS National BIM Report 2014). Level 1 BIM This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information. CAD standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE), often managed by the contractor. This is the level at which many organizations are currently operating, although there is no collaboration between different disciplines – each publishes and maintains its own data. Level 2 BIM This is distinguished by collaborative working – all parties use their own 3D CAD models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level. Design information is shared through a common file format, which enables any organization to be able to combine that data with their own in order to make a federated BIM model, and to carry out interrogative checks on it. Hence any CAD software that each party used must be capable of exporting to one of the common file formats such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange). This is the method of working that has been set as a minimum target by the UK government for all work on public-sector work, by 2016. Level 3 BIM Currently seen as the holy grail, this represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralized repository. All parties can access and modify that same model, and the benefit is that it removes the final layer of risk for conflicting information. This is known as ‘Open BIM’. Current nervousness in the industry around issues such as copyright and liability are intended to be resolved – the former by means of robust appointment documents and software originator/read/write permissions, and the latter by shared-risk procurement routes such as partnering. The CIC BIM Protocol makes provision for these. Update - The UK government reasserted its commitment to Level 3 BIM as part of the Budget announced in March 2016. Read more.  Looking further ahead, it is highly probable that collaborative working practices will ultimately filter through to the private sector ... 
  4. BIM saves time and money throughout all phases of design, construction, and ongoing property management.
  5. Let’s review some examples of how BIM can help the design process run smoother and faster.
  6. Here are some examples of BIM at work in the construction phase.
  7. Finally, here are some examples of how BIM saves time and money in the management phase of a project – often the phase most closely associated with owners.
  8. BIM allows owners to take control and harness the power of the Era of Connection. BIM increases transparency, quality, and efficiency so owners can: Improve building quality Significantly reduce building lifecycle costs Better understand design projects from beginning to end Optimize operational efficiencies Increase occupancy and use rates
  9. Owners shoulder 2/3 of the ongoing operating cost (estimated at $15.8 billion annually) that are a result of poor data and highly fragmented teams. 1 Michael P. Gallaher, Alan C. O’Connor, John L. Dettbarn, Jr., and Linda T. Gilday, “Cost Analysis of Inadequate Interoperability in the U.S. Capital Facilities Industry”, August 2004

  12. It’s better for organizations to start slowly with BIM adoption to ensure the best chance of success. Instead of deploying it across the board, a firm should use BIM on just a few handpicked projects, carefully and deliberately, to give team members a taste. If done well, pretty soon everyone wants to be on a BIM project, and expanding BIM across the organization becomes an organic process. In economics, the 'J curve' refers to the trend of a country's trade balance following a devaluation or depreciation under a certain set of assumptions.
