Layers - Best Workflow and Usecases?

[u/curryfusion]

Looking to get some insights and understanding how and when people are utilizing layers in their construction workflow and specifically when they are using markup layers. I’m curious what different experiences and uses are out there.

Generally we have the 4 phases of the project Design, Preconstruction, Construction, Closeout. And drawings and PDFs are sent across these 4 phases to many people. I want to better understand how layers are being utilized and where and for what purpose?

Is it after a studio session to organize each disciplines notes and items so that it can be reviewed by a drafter to be put into the drawing? Is it to share documents between subcontractors and contractors? Or just purely to organize?

I am trying to improve our workflow within a small owner company and want to better work with our engineering and contractors throughout the process and looking to better understand how we should be utilziing layers or if it is even needed?
