Welcome to the ARE Community, @ericj! Thank you for reaching out with your question.
I love that you pointed this out, as the architect’s coordination of consultants is common area of confusion as it relates to services provided. I actually posted a detailed explanation about this exact topic (see below). Hopefully it helps to clarify!
Please let me know if you have any further questions.
Happy studying!
