• Better quality product – coordination, space, change
• Easier checking, reduces human error
• Saves time
• More efficient
• Better communication
• Better costing and risk management
• Better procurement

“As a building services engineer I know how reliant
we are on the expertise of the whole supply chain to
get our designs turned into reality. I don’t want to
have to pretend that my opinions are correct just
because “I’m the consultant” and spend my energies
arguing with the sub-contractor even though their
views are perfectly valid. And let’s be honest, sub-
contractors know a lot more about the practical
challenges of actually installing and commissioning
systems than consultants.”

Collaboration Case Study: BHP Fitout Melbourne
• A.G.Coombs base building CADDUCT file imported into
Revit by Arup as basis for fitout design
• Fitout model created by Arup using BIM-MEPAus template
• A.G.Coombs won fitout tender
• Arup model used by A.G.Coombs to create their production
model
• 90% of information transferred
• Process saved time for both Arup and A.G.Coombs

“Working with Arup on this project, we have
developed new model workflows which are
proving to be extremely effective and are a great
example of IPD in action.”

Concept Stage – LOD 100
Early stage spatial
planning and co-
ordination by
consultant
29
Design Stage – LOD 200
Design by consultant but
less detailed than traditional
fully documented
(LOD200+)
Suitable for D&C
procurement
Sufficiently developed to
allow design functionality
30 Detail Design (300)
Detailed Design – LOD 300
More detailed than as
traditional fully documented
by consultant – hence
expect higher fee
Suitable for lump sum
contractor procurement
Or, first contractor design
stage in a D&C
31 Construction (400)
For Construction – LOD 400
Sub-contractor workshop
drawings
May integrate into
production workflow for
off site works
May be used on site via
mobile devices
32
As Built > FM – LOD 500
Record drawings
Model fully loaded with
all system design and
component data
Links to or embedded
maintenance
specifications and
through life asset
management tools

In Summary:
• BIM in MEP design is a done deal
• For the full benefits of BIM to be realised we need a more
collaborative industry driven by more intelligent
procurement processes
• In building services/MEP there is an emerging standard
and language around the use of LOD and BIMMEPaus
that can help drive convergence and benefits for all
