Building Information Modeling BIM Standards and Level of Development 3

Question 1

What is the 'Model Element Author' (MEA) concept as used in BIM protocols?

Accepted Answer

The party responsible for creating and maintaining a specific model element at a defined LOD

Answer

The MEA is the designated team member or firm responsible for authoring and maintaining a given element at the required Level of Development.

Question 2

Which US federal agency has mandated BIM use on major federally funded building projects?

Accepted Answer

General Services Administration (GSA)

Answer

The GSA's National 3D-4D BIM Program requires BIM on all major federal building projects and has published extensive BIM guidelines.

Question 3

What does the 'Spatial Coordination' LOD 350 requirement primarily address?

Accepted Answer

Clearances and connections between systems from different disciplines

Answer

LOD 350 spatial coordination requires modeling elements with enough detail to show how they physically relate to and connect with elements from other trades.

Question 4

In BIM, what is the purpose of a 'model progression specification'?

Accepted Answer

To define what information each model element must contain at each project phase

Answer

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.

Question 5

What is the difference between 'prescriptive' and 'performance-based' BIM requirements?

Accepted Answer

Prescriptive specifies exact software/formats while performance-based defines outcomes regardless of tools

Answer

Prescriptive BIM requirements mandate specific tools or formats, while performance-based requirements define the information outcomes the team must achieve with any compliant tools.
