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!

Name Boiler Inspection - Annual
Category PM
Status Not Yet Started
TypeName Combi Boiler

1. Shut down boiler - secure fuel supply and electric power. Lockout/Tagout as required.2. Inspect and clean boiler tubes.3. Check combustion chamber for air and/or gas leaks.4. Check fuel lines and connections for damage.5. Check for proper operational response of burner to thermostat controls. Adjust as required.6. Check and lubricate burner and blower motors.7. 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
