BIM and Soft Landings – A happy coincidence ? Nick Nisbet, AEC 3 & building. SMART BSRIA 26 th January 2011
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 building. SMART Nicholas Nisbet
The Cost of Inadequate Interoperability The Problem § The cost of not addressing interoperability in US is $15 bn p. a. § Probably more § Perhaps equivalent to £ 10/m 2 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 rules Source: Deke Smith (Chair)

IDM – Information Delivery Manual 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 Courtesy: Dianne Davis, AEC Infosystems

handover data captured and lost many times designer creates space and equipment layouts Equipment data captured during construction on invoices/reports construction contractor conducts postconstruction 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! 20 -Apr-08 24 Engineer Reseach and Development Center

enable and enhance commissioning management and commissioning processes ? • the capture of commissioning, pre-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
