The Current Picture - Chaotic


Facilities/Asset Management Specification

GeoSpatial Location of Objects & Elements

Around 350 Individual ‘Pieces’ of Information

Costing Requirements

Environmental Requirements

Energy Analysis Requirements

Building Program & Project Meta Data

Building Program & Project Meta Data

Manufacturer Specific Information

Physical Properties of Objects; Dimensions etc

Space/Fixtures Compliance

Code Compliance/ Occupant Safety

Ordering & Procurement Requirements

Construction Logistics & Sequencing

Building Commissioning Requirements

150 from Spec

100 from Manufacturers

150 Can come from the specification i.e. Lux Level. Provided we source the right information and use the right tools

& 100 are LOR Managed

Leaving around 100 to be ‘Managed’ through the Design, Delivery and Operational process by LOR – i.e. Order Placed Date.Needs suitable tools and processes to be achieved .

100 Are manufacturer specific i.e. Warranty Durationprovided we can access their content .

But

The Challenge – Volume of Data & Variety of Sources


Unique ID 001

Is the door the right spec?

Is the door the door the right price?

Has the Door been ordered?

When will it be delivered?

Is the room available?

Has the door been installed?

Has the door been approved?

Has the door been paid for?

Procurement Planning Commercial Design Management

The same unique ID in a door could be entered once, and used multiple times

The ID can be entered in to a model but by whom if the product is external?Need smarter tools and processes to effectively manage this information

The Challenge – Managing & Leveraging


External Protocols& Documentation i.e. CIC, AEC,

BG6, CPIx PAS/BS 1192 etc

Internal Protocols

Option 2 COBie principles; This Parameter must be populated i.e. FireRating But not prescriptive as to how

Option 3 Enhance the COBie principles; This Parameter must be populated and be named Prescriptively i.e.

FireRating = FD30s

Option 1 Give all the relevant elements in the model a Fire Rating

Protocol Options

Mindful of the impact and context of relationships with supply chain partners

The Challenge – LOD & Transformation


The Trial – Our Tools


Checking

2 tasks to be completed;One space and Multiple components identified as unclassifiedNote Stories above ground floor don’t have names

The Trial – Classification


Classification of Spaces Relatively Easy

Classification sets not picking up relevant model elements.

Syntax in SMC is underscores (correct) ArchiCAD uses hyphens

Exported to excel, fixed and re-imported

Repeated for Types and Systems



Listing Spaces



Listing Spaces had to be mapped

‘Category’ was re-mapped to embedded Uniclass2 data, and column ‘Name’ was reverted to ‘Category’



Listing Spaces had to be mapped But

‘Description’ column to link to an ArchiCAD property set, no ‘Classification References’ visible in the drop-down button (the zones in ArchiCAD have an IFC Property Set with this name).

Also ArchiCAD property set ‘IFC Attributes’ is not visible



COBie sheet produced for spaces!



Systems All items remained unclassified...

TypesOnly 2 items are classified...so what was special about these two?

Classification of Systems and Types More Difficult



Classification Duct Silencers -The only ones with a classification



Classification Duct Silencers

Other ducts analysed don’t have IFC Property called ‘Classification Reference’ attached.

Appears Solibri doesn't detected IFC data from the IFC Type Product level in ArchiCAD, only from the IFCEntity level.



Fixing the problem

To map Uniclass2 data from ArchiCAD for IFC Entities – classify each IFC EntitiesAll foundation pads needed classifying, then all the components were classified(excluding all openings and all spaces).



Listing The Types

The Trial – Issues


Listing Types

‘Category’ was re-mapped to the IFC model embedded Uniclass2 data, and column ‘Name’ was reverted to ‘Category’



COBie sheet produced for spaces



Strengths• Its a start...its a standard like HTML or SMTP it’s there to be used• It could reduce some of the transformation that occurs• Helps foster conversations on information, the right content at the right time

Development Areas• Some confusion between the product and the process• Some think it will just drop out like a schedule• Having to edit/reclassify the source model• Won’t ensure the outline specification, brief or KPI’s are being met on its own• Still work to do to integrate with FM systems and providers – What is COBie?• Drops 1 + 2 are the ‘easy bit’ its all about classification

3-5 need real thought & leadership• Space Race for manufactures content – who will ‘win’?• COBie not de facto – think about how to apply COBie; Who, What, When, Where, How & Why• Data Maturity – when is does it become reliable? i.e. Cost & Performance

Thoughts on COBie


BIM for FM - emerging field and yet to be completely provenInteroperability - Sharing nomenclature and geometry are the biggest barriers to full BIMData standards critical - Software life = 12 months, life of asset = 100 yearsThe Cost of BIM is more than just the creation – need to include for;

1) As Built models not just As Designed/Intended2) The translation of the construction BIM to something useful in FM3) Maintaining that BIM over the lifecycle

Classification is vital but things change post occupancy and during D & CWrong or unsuitable data is worse than no data at allPeople are important – Sophisticated tools/process won’t mean that behaviours & culture followBalance the juxtaposition between solving important problems and creating inertiaProblems precede Solutions; not the other way around

Some things off My Wish list...Need BIM Procurement > Consultants encouraging model sharing > Standard COBie IFC Psets> Vendors share geometry via IFC > Uniclass2 Resolution (No Trades!)

Thoughts on AIM...and...Life in General
