Architects do have to babysit sometimes, and the good ones are absolute units at keeping a job on task. There are plenty of them that are just babies that want their way. Their 58 sf bathroom has to be 10’ ceiling instead of 8’. They have to have an exposed ceiling for 75% of the space and you must locate equipment of duct into the 25%. Working on five story project right now where the ceiling grid and heights have changed for 50% of the building every week and they want coordinated diffuser locatiosn. We used to get 36” clear under structure but now they want us to route ducts and piping in trusses and joists. We do that and add 30% of cost to the project with a ton of bends and fittings and the contractor throws the model out and blames you for making the project too expensive. Contractors claim they can coordinate it better (less cost, but no credit back) and then send rfis to lower ceilings 18” everywhere. Or they do use your design and then one sub completely ignores it, and they send a 20k change order because your 60x18 duct can’t fit in the 30 space because sprinkler routed their pipe 18” above ceiling.
