BIM and Soft Landings –

A happy coincidence ?

Nick Nisbet, AEC3 & buildingSMART

BSRIA 26th January 2011

BIM

BIM

a quick introduction

developments in the US

BIM, as we practice it here

forthcoming developments in BIM

Is it better than current practice ?

Is it a real practical benefit ?

Where are the advantages to be had ?

Introducing

buildingSMART

Nicholas Nisbet

The Cost of Inadequate Interoperability

The Problem The cost of not addressing interoperability in US is $15bn p.a.

Probably more

Perhaps equivalent to £10/m2 in the UK

• 2/3 on Owners,

• 1/3 on Design and Construction

The Solution Think and Act Globally using International Standards

• Sharing building information

• Standard terms, properties, classification

• Common process descriptions

• Connect with related standards (geographic, supply chain)

Think and Act Locally• Extend with local data e.g.

• Provide local usage guidance

• Apply local business rulesSource: Deke Smith (Chair)

Requirement & Goal Standardize on information

needed for specific tasks within the building lifecycle

Development based upon open data standards used by all

Provides requirements to software companies

To improve the construction process: Information must be available when it

is needed Quality of information needs to be

appropriate

handover data captured and lost many times

designer creates space and equipment layouts

Equipment data captured during construction on invoices/reports

construction contractor conducts post-construction survey

wait many years to provide the survey data to the facility operator

once received, store the surveys in a boiler room

facility manager conducts separate survey to find “lost” data and finally…

hand load data into maintenance system

Handover process unchanged for over 100 years!



COBie

the Construction Operations Building Information Exchange format

where is COBie required? designer deliverable construction handover specification construction commissioning specs

capture data as you go design construction commissioning

easy to use spreadsheet each party adds only their part convertible to and from IFC

Check main flame failure protection and main flame detection scanner on boiler equipment with spark ingnition (oil burner).8. Check electrical wiring to burner controls and blower.9. Clean firebox (sweep and vacuum). 10. Check operation of control switches (i.e. steam pressure, hot water temperature limit, atomizing or combustion air proving, etc.).11. Check hot water pressure gages.12. Check condition of flue pipe, damper and exhaust stack.13. Check boiler operation through complete cycle (approximately 30 minutes). 14. Clean area around equipment.15. Complete work order time and materials. Mandatory comments required!!16. Report outstanding discrepancies to supervisor for corrective action.

enable and enhance commissioning management and commissioning

processes ?

• the capture of commissioning, pre-handover, handover, and post-occupation

activities

• greater control for clients of things that tend to get forgotten in the rush to

complete the build works?

enable and enhance FM and asset management?

• the three years professional aftercare process

enable and enhance the Soft Landings approach?

• ensuring that fitness for purpose doesn't get compromised by value

engineering

• reality checking design

• m&e specifications
