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 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?
