An introduction to 5D BIM
Automated Quantity Take-off
An introduction to 5D BIM
What are the efficiencies?
1. Clarifies the design2. Simplify & speed up take-off3. Visual record of measurement4. Risk reduction5. Focus on value adding: not take-off6. Early & improved value engineering
An introduction to 5D BIM
�Where does this leave our role?
�What’s the reality?
The 5D BIM Workflow
The 5D BIM Workflow
Source BSI: PAS 1192 Part 2
The Information Delivery Cycle
Employer Decision Points
The 5D BIM Workflow
�EIRs (Employer Information Requirements) informs the…
�BEP (BIM Execution Plan) tells us………
�Who authors the BIM
�Who manages the process
�Who detects clashes
�How information is exchanged
�LoD = ‘Level of Detail’ (or development/ definition)
�Software implementation strategy
Why use Specialist
5D Software?
Why not add a cost parameter to each
3D object in the authoring tool?
From the BIM we are able to……….
How is Information Exchanged
�CDE (Common Data Environment) such as Project Wise
�Native file format (dwfx, rvt, dgn, i.dgn etc. etc.).. or IFC?
�5D BIM Protocol – Using scheduling from C3D etc…
�What data is exchanged?
� Non-geometrical
� Geometrical
Non-geometrical Data Exchange
Geometrical Data Exchange
QA, QA and more QA
………OK, maybe just a little bit more QA
Standardised Libraries
WBS, CBS, Method of Measurement
Parametric Link – isolated view
Published data, 3D View and CESMM
Parametric Link – highlighted view
This link enables speedy VE
Outputs – To support EDPs
Cost Plans, Estimates, PTEs, BoQs

Barriers and Enablers to 5D BIM
�Barriers� Incomplete EIRs
� Poor data, naming conventions etc.
� Software interoperability
� Modelling standards
�Enablers
� A robust BEP including……
� Robust 5D protocols (modelling for 5D)
� Enthusiasm
� Basic modelling knowledge
� Trial and Error
What’s Next?
�4D
• Why not let the quantities drive the programme?
�6D+
• Carbon,
• Embodied Water,
• LCC
�Earned Value using the real time “As-Built” model?
