A gentle introduction to BIM
Rajan FILOMENO COELHO
Civil Engineer, PhD
Benoît DESCAMPS
Architectural Engineer, PhD
This presentation is designed
to provide you a quick but
comprehensive overview of
Building Information Modeling (BIM),
covering software, file format, and
implementation aspects,
but also emphasizing the benefits
of using BIM for all parties of a
construction project.
2. R. Filomeno Coelho – A gentle introduction to BIM (Kabandy©2016) – Slide 2
First of all, what does « BIM » stand for?
BIM = Building Information Modeling
development and use of a digital model
of the building project
BIM = Building Information Management
methodology and processes used to
manage the construction project during
its whole life cycle

Between two extreme views
The reality is somewhere in between…
In this presentation, we will see
what practical benefits
you can expect from BIM
« BIM is using BIM software
like Autodesk Revit for all my
projects »
Restricted view
« BIM is a totally new
paradigm that will
revolutionize the
construction sector »
Ambitious view

Main challenge in construction: collaboration
A construction project is essentially a collaborative work
Exchange of information between all parties (owner, architect, general contractor,
engineering offices, subcontractors, suppliers, etc.) is a crucial topic

Adopting BIM practices requires more effort in the modeling process,
but is aimed to harvest benefits during the whole life cycle
9. R. Filomeno Coelho – A gentle introduction to BIM (Kabandy©2016) – Slide 9
• In 2014, the European Parliament voted the European Union Public Procurement
Directive (EUPPD), recommending the use of BIM in public contracts
EU members must modify their legislation accordingly (no later than in 2016)
External constraint: European legislation on BIM

Motivation for adopting BIM
Beyond the legal aspect, the adoption of BIM should help you:
• getting a solution to technical and organizational issues
• increasing significantly the quality assurance
• reducing the costs and delays
• improving the project management during the whole life cycle of a building

• Lead parallel activities and
synchronize information
• Use BIM object libraries developed
by suppliers and subcontractors

Return on experience: extension in JFK airport, New York
• Terminal extension (1.2 billion $)
• Several stakeholders for civil engineering, buildings, etc. + public authorities
• Observations:
• Use of BIM models enhanced the integration of work by subcontractors
• On site virtual studio on schedule planning, site logistics, etc.
• Faster recovery in case of schedule issues
• Conclusion: Building Information Modeling can also be seen as a tool to improve the
management of a construction project

The BIM Manager
• BIM leader within a company
or on a specific project
• Set-up BIM workflow inside the office
• Co-ordinates the use of BIM on a
whole project
• Responsible for user access to the BIM
model
• Guarantees data security and archive
The BIM Coordinator
• He/she has to daily coordinate the
BIM models within his department
• Usually in addition to his/her
modeling tasks

Remarks:
• Transition between tasks: not always straightforward
• Integrated workflow using a proprietary solution collaboration? durability?
• How to exchange with other software products?
The simplest implementation: using a software suite

• IFC (Industry Foundation Classes): developed by the buildingSMART alliance®,
the IFC was created to promote the collaboration between all AEC (Architecture,
Engineering and Construction) actors. IFC complies with ISO 10303-21.

• Due to their open, free, neutral, durable character, open formats are likely to
play a more and more important role in the future
39. R. Filomeno Coelho – A gentle introduction to BIM (Kabandy©2016) – Slide 39
Open file formats
“For the most part, the
designers with whom we
have worked and collaborated
realized long ago
that committing to and
investing in the emerging
BIM standards and protocols,
such as IFC and
COBie, would lead to great
benefits in design
productivity and efficiency.”

• Although there is still some issues to be solve (e.g. security, legal, efficiency) to share
BIM models accross the web, the future trend will consist in providing access to BIM
models directly in the cloud
• Current platforms include:
• BIM Cloud (Graphisoft)
• BIM360 (Autodesk)
• Tekla Field 3D (Tekla)
• Aconex

42. R. Filomeno Coelho – A gentle introduction to BIM (Kabandy©2016) – Slide 42

• The final aim of BIM is to develop and use a digital model of the building, available
and synchronized for all parties, for the whole life cycle of the construction project

• Our guess: the use of BIM is likely to be encouraged by owners and public authorities
to better manage their building projects (operations & maintenance, renovation)
• In most medium- and large-sized companies, new roles will appear: BIM managers and
BIM coordinators
• Several software products are labeled as « BIM-compatible », but the key point is the
interoperability between programs to allow all parties to collaborate

Towards 6D BIM for construction
• 4D BIM: 3D BIM + time clash detection, etc.
• 5D BIM: 3D BIM + time + cost take off quantities, etc.
• Future trend: 6D BIM (= 5D BIM including all aspects of life-cycle
facility management) in a cloud-based environment
Already available with
Autodesk Navisworks,
BiMUp 5D, etc.
Autodesk Navisworks
