I don't know if your question can be answered from a contractor's or even an engineer's stand point.
I have found depending on various project specifications that fireproofing can be multi-jurisdictional (various trades responsibility).
I have noted from project to project that there is no general rule of thumb.
On occasion, if HVAC duct work requires fireproofing the mechanical contractor is responsible, if conduit systems or buss duct require fire proofing, the electrical contractor is responsible, ect, ect.
On the other hand, I have also seen projects where there is a separate bid package just for fire proofing in which the fireproofing contractor is responsible for all project fireproofing.
