Architectural and Structural Coordination

[mar_zan]

I have been trying to figure out what is best practice when coordinating an Architectural model with a Structural consultant's model. 

1. I have heard people discuss not modeling anything twice. So all structural elements are (eventually) only modelled by the structural team. But I am skeptical. 
2. And I have heard that the Architectural model does contain certain structural elements - namely concrete slabs and core walls. It is my understanding this has benefits of helping to coordinate structural placement, but also used for better control over dimensioning, joining with Architectural walls, applied finishes, door hosting, etc. 

I've read through an older forum post (Link) with people discussing this very matter, and I found the argument in defense of (2) to be stronger. Additionally, I see that the Autodesk 2024 Snowden Tower sample project (that shows an early CD complete coordinated project from different disciplines) to also follow (2). 

I was wondering how others handle this kind of workflow, as I am curious. 

EDIT: I referenced the wrong number. Put (1) but meant (2). Fixed now

For a beginner, I suggest you stick with the process the way it was intended.

- Double-modeling is not smart or efficient

- Link each other's models to stay on top of changes in those models - live coordination the best. Model things right the first time.

- Use copy\monitor and maintain it for the lifespan of the project

Oops botched my original post. Meant to say (2) is what I found stronger. 

Yes, copy/monitor. It would solve many of the issues of (1), such as joining, using as host etc.

But I've heard that Copy/monitor is somewhat finnicky? Or that it requires a higher level of Revit proficiency? I was worried it might be difficult to get right between the Arch and structural team.

But I will consider it more strongly since you've recommended it.

I guess I would lean between (1) but using copy/monitor vs (2) not using copy monitor and modeling certain important structural elements.

I remain skeptical about (1) without the use of copy/monitor though. Not being able to join, cut profile, apply finishes, etc. to structural elements would be a problem in my eyes.

Copy\monitored objects are not rigid elements. You need to experiment with this to learn more.

Copy\Mon walls from STR model will only bring in the structural wall. As for the finishes, you can model as a separate wall in the arch model. OR, you can MAP copy\mon'd wall\floor into another wall\floor type of different thickness and finishes included.

Copy\monitor of levels and grids is also important. You have the option to add an offset for levels, so the arch level can be at FFL while the str level can be TOS or TOC or whatever they set it to.
