All Laing O’Rourke Projects to be BIM by 2010
DfMA (Design for Manufacture & Assembly)
Do nothing?
Relax – no pressure
Lots of it!
Frustration
Conflicts
Assign lead
We knew we had to fully understand BIM as
our main client group is government funded
Pathology scheme won in 2011
Given option to use BIM
Jumped at chance
Full design team (architect/structural
engineer, M&E engineer, contractor)
willing to try BIM
Contractor was kind & stated you can go
back to 2D – phew!
What they wanted
Floor areas
Linear measurements
Wall areas
Ceilings – coordinated “areas”
Envelope quantities
FFE schedules
Model for federation “clash detection”
What we wanted
No real concept at this point of what could
be acheived
Upgrade selected users to “Architect” version as fundamental version
did not give us the tools needed. Being selective was a mistake.
Basic 3D training in VectorWorks Architect
Advanced 3D training in VectorWorks Architect
• Spaces
• Stories
• Model set-up
• Workgroup ref
In-house training
• Strategic steps
• drop in sessions
• one-to-one
• “just in time”
• upskill a team
2D process had to continue, speed of scheme dictated this
3D process was started in parallel
Lead-in
Inaccurate
Masked issues
Visual only
BIM Development
Generic modelling
Low level of development
Unintelligent “limited data” but sufficient to meet protocols
We became aware very quickly that
the 3D team was on the tail of the 2D
team
The images and results from the 3D
model were noticeably quicker and
more accurate
The 3D images were conveying the
design better
We took the decision to stop the 2D
team and apply all resources to 3D –
this then delivered the planning
drawings via the model
Drawing structure – based on Computers Unlimited Training

Common Exchange IFC
Luck?Learn?
Feedback?
Did the contractor want IFC? Not really, they wanted native file format but it
soon became obvious there were three authoring platforms in the team.
NATIVE MODEL
VW IFC MANAGER
Test prior to issue “very important”
Was the output useable?
Validation tool – FREE Solibri model
viewer
Architectural
Structural
MEP
Contractor – BIM Manager
Software – Navisworks
Fortnightly Design Team Meetings
Reports “clashes” issue by BIM
Manager
Justification – it works
Clash detection
Thorough reporting
Report on clashes for discipline to
correct prior to next Design Team
Meeting.
BIM Manager ran custom rule sets to
establish prefabrication elements.
Co-ordination
Pre-cast concrete deck
Pre-cast concrete stairs
Pre-cast concrete lift core
Pre-case concrete twin-wall
Did it all work? YES but no.
IFC geometry issues
Demonstrates necessity to
validate
Time needed to fix issues
Exchange sample files to establish grid/origin – appreciate this is basic CAD but it’s more important than ever.

The process taught us about protocols
We have updated our BMS in line with GCS
PAS1192, BIM protocol etc
Training plans in place
Train staff in 3D authoring – BIM protocols
Assign/identify BIM advocates within the practice
Set up templates
Generate practice content “protocol” “validate”
Business goals
Informing clients of government requirements
Engaging with consultants
Participating in events
Getting the message “out there”
Building links with local education providers
Continual developments
Keeping informed on industry progress
Sharing information with clients
Listening and understanding peoples concerns
Be proactive – not reactive
Collaborate – share – learn
Validate
Don’t be too hasty
Interoperability testing
2013 was about learning and education
2014 is about…
IMPLEMENTATIONJust do it!
PRACTICETime to understand
Mindshift
GET IT WRONG!Capture mistakes and
share
COBIENo? Yes? When?
Focus on getting Level 2- getting systems in place and practicing.
WHY BIM?Why not? Show me a
better way!
LEVEL 2/3?Focus on Level 2 –
getting systems in place and start practicing.
OPEN BIM?This has to be the way
forward.
ISN’T IT JUST CAD?It’s CAD-focused but that’s only one part of
the jigsaw.
This has to be the way forward.
