As architects, we do not "sign off" on orders for stuff like cabinetry, counters, rebar, windows, etc. We review shop drawings and submittals for material, spec, color, finish, etc, but *not* quantity and stuff related to field conditions. We aren't responsible for making sure shop drawings conform to field dimensions, that's on the GC. As they should want it to be! A good GC doesn't want the *architect* messing with stuff like that; a bad one does, so they can pass the buck. While we're at it, GCs, if you change a material or a spec, you need to get approval from the architect. This isn't bc architects are obsessive control freaks, this is to protect yourself. If you deviate from the CDs, without approval from the architect, it's on your head if anything fails or goes wrong. But what if what the the architect put in the drawings is wrong or a bad idea? Then send them an RFI, or an email, or bring it up in a meeting and make sure your voice is heard. If you have a legit concern, you should go on record with it, and come to the table with proposed solutions backed with real info. Proper procedures during construction protect everyone: GC, owner, and architect. (PS Developers: if you don't know how Contract Administration (aka the construction phase) should work from a legal, contractual, and liability standpoint, STOP and learn it. Messing up CA has financial and liability implications both during the project *and* during the statute of limitations after the project ends...5-7 or more years!)
