Read the first 6 BIM Standards and Level of Development flashcards as text
What is the 'Model Element Author' (MEA) concept as used in BIM protocols?
Answer: The party responsible for creating and maintaining a specific model element at a defined LOD
The MEA is the designated team member or firm responsible for authoring and maintaining a given element at the required Level of Development.
Which US federal agency has mandated BIM use on major federally funded building projects?
Answer: General Services Administration (GSA)
The GSA's National 3D-4D BIM Program requires BIM on all major federal building projects and has published extensive BIM guidelines.
What does the 'Spatial Coordination' LOD 350 requirement primarily address?
Answer: Clearances and connections between systems from different disciplines
LOD 350 spatial coordination requires modeling elements with enough detail to show how they physically relate to and connect with elements from other trades.
In BIM, what is the purpose of a 'model progression specification'?
Answer: To define what information each model element must contain at each project phase
A model progression specification maps each building element to its required LOD at each project phase, giving the whole team a clear roadmap of model maturity.
What is the difference between 'prescriptive' and 'performance-based' BIM requirements?
Answer: Prescriptive specifies exact software/formats while performance-based defines outcomes regardless of tools
Prescriptive BIM requirements mandate specific tools or formats, while performance-based requirements define the information outcomes the team must achieve with any compliant tools.
Which standard defines the US National CAD Standard's integration with BIM file naming conventions?
Answer: NCS (National CAD Standard) published by CSI, AIA, and CEDIA
The National CAD Standard published collaboratively by CSI, AIA, and related organizations provides file naming and layer conventions that integrate with BIM workflows.
