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
