:confused:I am a bit confused on the requirement for shop drawings. Per spec they are supposed to be part of the submittal package. But I dont see why. The building is a LEED Certified and there are all kinds of requirements for qualifications for installers. The EE layed out the circuits, panels, some larger conduits and wire sizes ,fixtures, etc. The only thing that isnt on there is the home runs. It seems like a big waste of time if I have someone make shop drawings for homeruns and run into a spaghetti mess of duct work and plumbing in the field. Isn't this why the Architect hired an EE to design the job? Am I missing something here? What are the shop drawings for exactly?

If they drew in the circuits or notated them in some way - all except the HR's - are they asking you to annotate them? In submitals or post work - 'as builds'?

What did they give you?
And:
What are they asking for?

Anyway you're right - it would be a waste of time for them to put HR's on there only to find constant obstruction. But I doubt they want you decide on a path and stick to it just yet. And if they are - you'll probably need a whole lot more information from all other trades to do it.
 
Our shop drawing usually have information beyond what the EE has come up with. They show greater details, such as the number on conduits on a rack, locations of pull boxes, conduit elevations, etc. These are typically coordinated with the other mechanical trades to ensure that the conduits aren't in the way of the tin or sprinkler pipe etc.

Also we would submit shop drawings showing switchgear layout, electrical closet layout, transformer locations and other parts of the electrical installation for review by the EE.
 
To me it sounds like ther are asking for "as-built" documents, not shop drawings. If they are asking for this during the submittal portion of the project they are expecting too much. In our design office the only exception to this would be mechanical/electrical room layouts (as others have mentioned).
 
I agree with a lot of everyones statements, but I think the real kicker is if you have to pay
to get electronic files of floor plans.

If the Job is completed on CAD then they will probably want CAD files of your work.

I can see a minimual charge for someone's CAD operator time, but don't be surprised if they hit
you with a sheet charge, IE I've heard of 125.00 to 250.00 each!

Talk to the EE first, if he's indepandant of the Arch. All you'd want is simple based drawings of walls,
room names, door swings, lights, receptacles, switches.

You only need the EE's drawing with the Architectural stuff (previously said)

How you handle that information; such as CAD, type of software / version, software type is on you.
Hopefully you have someone in-house that understands the suttle differences that "CAD" present!
For goodness sakes don't ask for anything of file conversions!
Get a Copy, know the version and type of software that its coming from.

Hope that helps, Good Luck

I think that the as-builts come after you are finished. There's fancy lingo for the pre-construction and post-construction prints. I am going to call the EE and see what they say.
