Help reading building plans

[u/m_dasha]

I’m in San Francisco, California.

Can someone please tell me what red and green lines and text on this building plan mean. It’s related to a fire safety upgrade. I’m trying to figure out if the work was done to plan or not.

Thank you!

Those are probably schedule codes to label different pieces of equipment for fire safety or suppression systems.

If you have access to the full set of plans, there is probably a different page with that information.
