Hi, for the below question, can you explain why the Owner would need to hire the Structural Engineer? Or is it that the architect is getting permission from the owner to hire a Structural Engineer? It’s my understanding that the Architect hires the Structural engineer.
As part of a renovation project, a new rooftop HVAC unit will be added to a building. The mechanical engineer needs to know that the roof structure is adequate to support the new unit. There is no structural consultant already on the job and one will need to be retained.
According to AIA C401 document, what is the communication protocol for requesting the appropriate consultant to perform the analysis?
Answer: Mechanical Engineer -> Architect -> Owner -> Structural Engineer
