BIM - Interoperability and data exchange Flashcards
(20 cards)
What are the three meanings of LoD?
Level of development, detail or definition
What is the objective of LoD?
To help teams, including oweners to specify BIM deliverables. To help design managers explain to their teams the level of info that needs to be provided at various points.
When is a low level of detail fine to use?
At an early project stage as a place holder in the model.
What is interoperability?
The ability of computer systems or software to exchange and make use of information
Information is vital for the successful delivery of a project, what needs to be efficient for this to happen?
Sharing of information.
What has been a major issue in the construction industry worldwide?
Poor ineroperability of information.
Why is interoperability important?
-Large amount of ppl from different domains
-Distribution of design tasks, several different software
-Design decisions strongly independant
-Frequent design changes occur.
What was the past method of data exchange?
Sending paper drawings.
What is the modern way of data exchnage?
Exchanging digital data
What is ‘bilateral interfaces’?
When there is data exchange between each indiviudal person.
What is common data format?
Where all information is shared in the product model, much simpler and effective.
What is “closed” BIM?
All software from the same vendor, e.g. just Autodesk
What are the limitations of “closed” BIM?
Relies on others on the project to have the same tools, those who don’t will have to convert files.
Managing data could be tricky
What is “open” BIM?
Software from different vendors used
In “closed” BIM, what should be used throughout?
A standard format, so you are able to access your data in the years ahead.
What are the limitations of “open” BIM?
Potential information errors during translation between different software projects.
What are the 6 principles of openBIM?
1 - Interoperability is key to the digital transformation
2 - Open and neutral standards should be used
3 - Reliable data exchnages depend on independant quality’s benchmarks
4 - Collaboration
5- Flexibility of choice of tech provides more value to all stakeholders
6 - Sustainibility is safeguarded by long-term interoperable standards.
The anaylitical models created by structural analysis must be consistently coordinated with respect to general framing layout. Once analysis is complete, what should the design documentation be modified to reflect?
The most current design.
With bidirectional interoperability between a reference model software and strucural analysis software, what does this help?
Reduce the time needed to create and update multiple analysis models, avoid potential errors resulting from manual coordination between analysis results and construction documenation.
