IFC ChallengesIFC Challenges
IFC does work
What exactly is an IFC model or an IFC file ?• standard format to describe a BIM• how information should be provided/stored through a building
project’s lifecycle.
Will the same users produce the same model with different software?
Will different users produce the same model with the same software?
Is it enough to ask for IFC files in a project?
IDM makes IFC work in business processes
Deployment ChallengesDeployment Challenges
• Motivation to ask for a BIM/IFC ?• Motivation to deliver a BIM/IFC ?
• Extra work • paid • specified • validated
• Relation to contracts for various business processes
• How can users of software make sure they deliver what is requested, without having to understand every aspect of the BIM?

Detailed Design
IDMIDMIDM target both BIM users and solution providers
For BIM users•simple to understand, plain language description of building construction processes •requirements for information to be provided •additional information that may need to be provided by the user
For BIM solution providers•identify and describe the detailed functional breakdown of the process •describe IFC capabilities needing to be supported for each functional part in terms of the entities, attributes, property sets and properties required
IDMIDMTo improve the construction process:
• Information needs to be available when it is needed
• Quality of information needs to be appropriate
