Users and benefits
Applications
• Classification and structuring
• Describe simple and complex systems with the same flexible method
• Identification (reference designation)
• Keep tack on functions, products and placements through out the life cycle
• Hierarchical requirements and follow-up
• Construction entity → Built space → Construction element
• Used during the whole life cycle
Applications
• Cost calculation, product planning and delivery
• Connect costs, product activities and time to construction elements
• Technical specifications using production results
• Connect digital object and properties• The construction element knows all relevant information
about itself
• Find construction products• Use properties of construction elements to find matching
products
Applications
• Translate between classification system
• Connect between IFC, Omniclass, Uniclass, Talo…
• Connect to external recourses
• bSDD, environmental data bases and other internet sources
• Operation and maintenance
• Connect maintenance activities to object
• Decommissioning
• Safe demolition and recycling thanks to relevant object information
• Developers, public and private facility owners
• Architects, designers, technical consultants
• Software companies: modelling (CAD/GIS), project management, calculations etc.
• Contractors within construction and facility management
• Building material industry
• Product declaration, qualification for procurement
Users
• Possibility to start the process with generic objects
• Design to any level: function, constructive type or components
• Search for products based on requirements
• Software always uses the same data structure and attributes
• Information deliveries structured the CoClass way regardless of client
• Identification of objects
• No need to maintain internal classification systems and structures
Benefits in design
• Procurement at any level: function, constructive type or components
• Compete with proprietary solutions to functional requirements
• Search for products based on requirements
• Common language for electronic trade and logistics
• Identification and localization of objects for deliveries and construction
• No need to maintain internal classification systems and structures
Benefits in construction
• Efficient asset management
• Synergies in planned maintenance
• Control of products and materials
• Reuse of information
Benefits in operation and FM
Classification
for the built environment
What is classification?
• An object is any part of the perceivable or conceivable world
• All object has properties
• To classify is to divide groups of objects for a specific purpose
• A class is a group of object with one or many shared properties
Principles in CoClass
• Clear criteria for classification
− Function, form or location, or a combination of these
− Hierarchical classes
• Unambiguous classes
− Code and definition are primary;
the class name is sometimes a collective abstract term
• Few but stable classes
− Function based classes opens for alternative technical solutions
Classification principles
• Classes based on inherent function
• What the objects do ”by themselves”
when they become occurrences
This is an article, not a class!
• Classes based on inherent function
• What the objects do ”by themselves” when they become
occurences

Based on, and affect standards
• ISO 12006-2 gives principles for classification
• IEC 81346-1 gives principles
for reference designation
• IEC 81346-2 gives classes
of components and of built space
• ISO 81346-12 gives classes
of functional and constructive systems
• Object and property mapped to IFC
• Prepared for mapping to bSDD

SummaryCoClass:
• can be used by all parties
throughout the life cycle
for the whole built environment
• is based on international standard
• will – I hope – be expanded and usedbased on international cooperation
