What is Building Information
Modelling (BIM)?
There are many definitions of what BIM is, but at its core
BIM is:
‘…a managed approach to the collection and
exploitation of information across a project.’

The BIM Process
1 Process for data management (BS 1192/PAS 1192)
2 A method for housing the data (BIM software model)
3 A method for distributing the data (COBie + other
documents)
 From inception to demolition

So why all the fuss now?
 Government will require fully collaborative 3D BIM (with
all project and asset information, documentation and
data being electronic) as a minimum by 2016.
 Levels of maturity
 BIM Level 2

Overview of information
management in PAS 1192-3
 Organizational information requirements (OIR)
“data and information required to achieve the organization’s
objectives”
 Asset information requirements (AIR)
“data and information requirements of the organization in relation to
the asset(s) it is responsible for”
 Asset information model (AIM)
“data and information that relates to assets to a level required to
support an organization’s asset management system”

Building Information Model (BIM)
Protocol
“The Protocol identifies Building
Information Models that are required
to be produced by members of the
Project Team and puts in place
specific obligations, liabilities and
associated limitations on the use of
the models. The Protocol can also
be used by clients to require the
adoption of particular ways of
working – such as the adoption of a
common naming standard”

GSL (Government Soft Landings)
Soft Landings
“…a form of graduated
handover for new and
refurbished buildings, where
the project team is
contracted to watch over the
building, support the
occupant and to fine-tune
the building’s systems for up
to 3 years post-completion.”

Government Soft Landings (GSL)
 GSL
– Taken the principles of Soft Landings and developed it for use
within its own procurement strategy
– Differences – the use of metrics to demonstrate compliance
with the stated project outcomes
– Four focus areas:
1. Functionality and effectiveness - buildings designed to meet
the needs of the Occupiers; effective, productive working
environments
2. Environmental – meet Government performance targets in
energy efficiency, water usage and waste production
3. Facilities Management – a clear, cost efficient strategy for
managing the operations of the building
4. Commissioning, Training and Handover – projects delivered,
handed over and supported to meet the needs of the End Users

Classification
Classification




Searching for like ‘things’ in a
model
Combining models as all ‘things’
are consistently classified
Enabling the aggregation of like
‘things’ in a model for the
purposes of measurement,
purchasing, maintenance, etc
A common language for all people
constructing and managing assets

Example: Classification in a hospital FM
environment
Classify four ways:
 Spaces – every space is classified
 Activities – all the activities which can be carried out within each space are
classified
 Systems – the systems serving each space are classified
 Objects – the objects belonging to each system are classified
In the event of chiller failure:
 The spaces served by the chilled water system can be identified
 The activities affected within those spaces can be identified
 The objects in the rest of the system(s) can be identified

….so if you meet the requirements set out
in these seven components, then you will
be Level 2 BIM compliant.

The potential
 Strip the waste from processes. Achieved by sharing
information…. To enable right first time installation and
operation that meets the needs of the users
 Information about the use of the building which is
informative to the operators
 Better buildings, with clear operational efficiencies and
the best whole life value

BIM in Operations
 The majority of operaters, owners and occupiers (69.0%)
recognise that BIM will become increasingly important in
day-to-day working practices within the next 2-3 years (if
it is not already).
 BIM is definitely here to stay and is growing in
importance

Organisational requirements
 PAS 1192-3

Potential for Operations
 FM engaged at start of construction projects with supply
chain considering client input
 User focus during the construction process
 Competitive advantage in the FM supply chain
 Clear understanding of operational risk

BIM Summary
1. What? a managed approach to the collection and
exploitation of information across a project.
2. Why? Government will require fully collaborative 3D BIM
(Level 2) as a minimum by 2016.
3. How? UK Government’s BIM Level 2 requirement by use
of seven components (pillars).
4. Potential….There is a huge potential, particularly for
operators
