Who is responsible for coordinating owner furnished equipment?

B101 sec. 5.1 says: the owner should provide information on special equipment. 

B101 sec. 4.1.1.28 says: furniture, furnishings, and equipment design is an additional service.

C401 sec. 5.3 says: Upon consultant's request, the architect shall provide to the consultant (1) detailed layouts showing the location of connections, and (2) tabulations giving sizes, loads and other information on equipment designed, specified or furnished by others. 

Reading the contracts I would say the owner is responsible for coordinating unless the owner has agreed to an additional service for equipment design. However, in one of my practice tests I receive this response for one of my questions. 

"The architect is responsible for updating the plans for layout of the space, including the equipment. This is for multiple reasons. This is because the architect is responsible for accessibility, life safety, and building codes and the equipment supplier is just selling equipment. Must coordinate the work with the engineers and the architect is responsible for accessibility, life safety, and building codes and the equipment supplier is just selling equipment."

Can someone clarify the difference between equipment coordination vs. equipment design and the architect and engineering consults' responsibility for owner furnished equipment?
