Hello, I'm working on sorting out our LOD in house, aiming to match-up to what some BIM Execution Plans out there are requesting, and I've come to a stumbling block in the Model Element Table and hoping someone here can clarify and/or suggest how to handle this:

For example, the BIM Execution Plan is asking for this (which from what I understand is Uniformat Level 1-3):

D3020 Heating Systems LOD 300

And in house we have worked this out (Following the Uniformat Level 1-4 schema):

D3020 Heating Systems
D3020.10 Heat Generation LOD 300
D3020.30 Thermal Heat Storage LOD 300
D3020.70 Decentralized Heating Equipment LOD 300
D3020.90 Heating System Supplementary Components (N/A, Because we never include these items)

What is our LOD then for D3020 if we can't complete a category such as in the example above?

Thank you in advance for the assistance.
