BIM – What's required for BIM Level 2?

© BRE 2014

BIM Maturity Levels – Strategy Paper 2011

0 - Unmanaged CAD probably 2D, with paper (or electronic paper) as the most likely data exchange mechanism.

1 - Managed CAD in 2 or 3D format using BS 1192:2007 with a collaboration tool providing a common data environment, possibly some standard data structures and formats. Commercial data managed by standalone finance and cost management packages with no integration.

2 - Managed 3D environment held in separate discipline “BIM” tools with attached data. Commercial data managed by an ERP. Integration on the basis of proprietary interfaces or bespoke middleware could be regarded as “pBIM” (proprietary). The approach may utilise 4D Programme data and 5D cost elements.

3 - Fully open process and data integration enabled by IFC / IFD. Managed by a collaborative model server. Could be regarded as iBIM or integrated BIM potentially employing concurrent engineering processes.

BIM User Manual for Home Builders

BIM-manual with guidelines• modelling in open BIM• export in open BIM

BIM-Manual covers• energy simulations• cost calculations• ventilation design• roof trusses

© BRE 2014

How to increase productivity and profitability through the use of BIM

– All projects are designed (architect and structural) in BIM (ArchiCAD)– IFC export to other domains– In some projects they make complete models (all domains)– BIM quantity take off – cost calculation

© BRE 2014

Norgeshus "concept homes"

– BIM is a success – 20% reduction in building cost with detailed

BIM-design – Less conflicts and clashes – Better procurement – Better material deliveries

– 100 concept homes built in 2013.

© BRE 2014

Examples - What BIM has improved

– Clash detections: exhaust and supply air ducts misplaced in wall

– Action: Extending air ducts to fit in wall

– Profit: Correct quantities, avoid stop in production on building site

© BRE 2014

– Clash detection: Downlights clash with ventilation, beams and air ducts

– Action: Led-box moved

– Profit: The correct choice of product, avoid encasing and stop in production

Examples - What BIM has improved

© BRE 2014

Examples - What BIM has improved

• Clash detected. Ventilation pipes 98mm• Action: increase wall to 148mm• Profit: Avoid thicker walls and space adjustments

Lessons learned – Home Builders - Norway

– Start with owners and motivate them by seeing the potential for improved sustainability (less energy consumption, less construction material usage, less waste…)

– Motivate government to see the potential for efficiency and freeing up resources for more value adding activities

– BIM is possible today – and it is profitable– A change in your business processes are needed– Demand IFC import/export from your software vendor– Focus on knowledge and education – Domain status

– Many architects are working with BIM – Structural engineers knows BIM– Ventilation design is done in BIM– Electrical- and plumbing design are not BIM in small projects – Big contractors and builders are using BIM– SME contractors and builders are starting utilizing BIM – Plumbers and electricians are behind
