BIM and Project Controls: An overview of 5D BIM – Ian Levers

Agenda � An introduction to 5D BIM � The 5D BIM Workflow � Barriers and enablers to successful 5D BIM � What next?

The 5D BIM Workflow What is 5D BIM?

An introduction to 5D BIM Line Object Time - Cost – Drawings Models Schedules Plans /Estimates 3D 5D 2D 4D Automated Quantity Take-off

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

An introduction to 5D BIM � Where does this leave our role? � What’s the reality?

The 5D BIM Workflow The 5D BIM Workflow

The Information Delivery Cycle Source BSI: PAS 1192 Part 2 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?
