Purpose, goals and challenges (Lab)
The main purpose with establishing the BIM Collaboration Lab is to perform advanced research and development on through life support
• The vision of the unbroken information-flow when using BIM and GIS
• open data – i.e. o Computable o Object oriented, structured o Understandable – common concepts! o Standardized – international if possible
BIM (Building Information Model / Modeling) Building Information Modeling (BIM) is defined as a technology to create, communicate and analyse Building Information Models (BIM).
BIM, what is that?
BIM Handbook, second edition, Chuck Eastman, et al., John Wiley (2011)
• Building models contain digital objects representing buildings and infrastructural complexes with related spaces, building elements and components.
• The objects can be associated with computable geometry, spatial information, data attributes and parametric rules.
• The digital objects contain data that describe all relevant characteristics for analyses and work processes needed to perform controls and simulations of the functions and processes of the represented construction entities over their whole lifecycle. (Eastman, et al. 2011, p 16).

Why standards? - Rates of Change
Life of CAD System: 10 years
Time between CAD Versions: 6 months
Life of Computer: 3 years
Life of Operating System: 18 months
Life of Product: 70 years + time
3. Our view on Req Mgmt, CM and PLM
Collaboration - Principles
� Single system environment + Configuration management, tracing, etc − High initial cost − No room for best of breed − Impossible to impose in collaboration
� Separate systems joined in point-to-point transfer + Low initial cost for integration + Best of breed system selection − Impossible configuration management, tracing, etc − No information control and assurance − High cost of ownership
� Separate systems joined in via information hub + Configuration management, tracing, etc + Low initial cost + Information control and
assurance also across the EE + Best of breed system selection

Product Life Cycle Support (PLCS) Introduction
»A joint industry and government initiative to accelerate development of new standards for product support information »An international project to produce an approved ISO standard within 4 years
− Commenced November 1999 − PLCS, Inc closed down 2004 − Standard published in 2005
»PLCS will ensure support information is aligned to the evolving product definition over the entire life cycle »PLCS extends ISO 10303 STEP - the STandard for Exchange of Product model data
C O P Y R I G H T E U R O S T E P G R O U P
The PLCS way: PDM core (from STEP) » Notions
− Product: » A “thing”, something to
manage » Product / version / definition
The Product i.e. the thing to manage
Its version(s) The context/view (displipline + life cycle stage)

Ex: The Wall with the identifier 231 has 2 versions v1 and v2. V1 exists in the architure design view, v2 exists in the architecture design and structural design views

• Assembly relationships in PLCS are subtypes of view_definition_ relationship. This enable to define assembly in the context of a view.
• In this example, the version v1 of the Wall 231 is nested by the version v2 of the Opening ABC in the “Architecture Design” view
• If we now assign an effectivity on the assembly relationship, we can control the validity of this structure.
• It could be a proposed start date to indicate a proposal.
