An introduction to 5D BIM What are the efficiencies?
- 1. Clarifies the design
- 2. Simplify & speed up take-off
- 3. Visual record of measurement
- 4. Risk reduction
- 5. Focus on value adding: not take-off
- 6. Early & improved value engineering

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
SLIDE 10
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
SLIDE 16
………OK, maybe just a little bit more QA

Standardised Libraries WBS, CBS, Method of Measurement

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
SLIDE 26
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?
