When choosing BIM Software…..
The BIM dimensions
7D Lifecycle management
8D BIM saves kittens from trees
9D BIM for world peace…
What are BIM uses?
“a method of applying Building
Information Modeling during a
facility’s lifecycle to achieve one or
more specific objectives.”
PENN State University BIM Execution Planning Guide
What are BIM uses?
Plain Language Questions?
A set of plain language questions
that a client intend to answer at
each stage of a construction project.
Key decisions such as whether to
proceed to the next work stage or
not will be made based upon the
answers to these questions
Once you have your uses and your questions …
Capture them in an EIR
The Employer’s Information
Requirements (EIR) form part of the
appointment and tender documents
on a BIM Project.
The EIR define which models need to
be produced at each project stage –
together with the required level of
detail and definition. These models
can be key deliverables in the
‘Information Exchanges’ –
contributing to effective decision
making at key stages of the project.
So your tender has an EIR based on your BIM uses…
The Main Contractors will respond with a BIM
Execution Plan
There are Pre-Contract and
Post-Contract versions of
the BIM Execution Plan.
Where possible a standard
template should be used to
simplify tender scrutiny.
The CPIx have excellent
templates for this reason
You’ve asked for your Information…
Your chosen contractor has a plan to deliver it…
So how are you going to use it?

What are Open BIM Standards?
=
Common Data
Common Data
Environments
Open BIM is a universal approach to the
collaborative design, realization and operation
of buildings based on open standards and
workflows.

- International Framework for Dictionaries

- Information Delivery Manual
MVD - Model View Definitions

What is IFC?
IFC definition….
a common data schema that makes it possible to hold and
exchange data between different
proprietary software applications. The data
schema comprises information covering the many
disciplines that contribute to a building throughout its
lifecycle: from conception, through design, construction
and operation to refurbishment or demolition
IFC misconceptions….
“IFC loses
important
data…”
“It’s Impossible to get a
good IFC out of some BIM
authoring software…”
“I exported and re-imported
an IFC and there were
missing elements…”
IFC reality….
IFC doesn’t yet
replace your
native design
files…
But it enables
you effectively to
share your
designs.

So client on you projects are ready to accept IFC
models right?
…Thought not, very few people are
…Luckily there’s COBie!
What is COBie?
COBie…
… is a Model View Definition (MVD) as defined by buildingSMART
… is a subset of IFC with some additional data
… simplifies the work required to capture and record project handover data.
… captures data as it is created during design, construction, and commissioning
… does not require endless spreadsheet editing
… is a UK Government requirement by 1st 2016
Why COBie?
Once a validated COBie dataset has been
delivered to the building operator matching
the built asset; all operations and
maintenance data can be interrogated from a
single place.
Meaning this type
of information
about built assets…
…Instead of this
B 555 roadmap - The Mandate taking shape
The BS/PAS 1192 series of
standards are the most
important releases to date.
PAS 1192:2 Concerns the
Level 2 Delivery of projects.
PAS1192:2 What’s it all about?
characters
What is BIM Data?
Documentation
Information for use in the briefing,
design, construction,
operation, maintenance or
decommissioning of a
construction project, including but
not limited to
correspondence, drawings,
schedules, specifications,
calculations, spreadsheets
NOTE Documents must either be
immutable or
incorporate a means of controlling
changes.
What is BIM Data?
Non-graphical data
data conveyed using alphanumeric
characters
What is BIM Data?
Graphical Model
data conveyed using shape and
arrangement in space
… ALL of this data is to be delivered
to and shared through a Common
Data Environment approach. It is a
‘Fundamental Principle for Level 2
information modelling’
=
Common Data Environment
Common Data Environment (CDE) – PAS1192:2
‘Single source of information for any given project,
used
to collect, manage and disseminate all relevant approved project
documents for multi-disciplinary teams in a managed
process.’
‘NOTE, A CDE may use a project server, an extranet, a
file-based retrieval system or other suitable toolset’
What are the issues?
Documents and drawing are easy to share – 4Projects have been facilitating effect collaboration around
these for years
But getting the most out of sharing Building Information Models presents a new challenge…..
How does everybody see the model and it’s data?
Ownership the federated information?
Can unfinished
worked be shared to assist the design process?
How is the Information exchange data compiled and validated?
PAS 1192:2 and 4Projects Workflows are here to help
So that’s the theory…. What about the practice?
Single Design Models
SDMs
Master Design Model
MDMs
But doesn’t this only apply to buildings?
The VSU model encompasses the entire project
and incorporates 18 discrete design disciplines,
showing how the entire project fits together.
[The] Federated project supply
chain [produced] a co-ordinated
information model
To maximise interoperability between disciplines,
LU’s preferred collaboration software, [ ]was
used wherever practicable. When this was not
possible, the transition of electronic information
between the different platforms being used was
assisted by tailoring software configurations and
using ‘platform
agnostic’ models.
Translating the B555 Roadmap into the CDE.

How does this fit with contracts, appointments, briefs etc…
Confirmation from the major contract providers has been received that on minor clause amendments
are required to incorporate BIM Protocol to sit above the contract. The clause changes must be
cascaded throughout the project appointment for successful collaboration.
The PAS1192:2 Level 2 Fundamentals include the provision Employers Information Requirements, from
Client to Supplier and a BIM Execution plan in return from Supplier to Client.
