Have a very small space say 50'x30' that have been gutted and we are renovating.
I have the other trades drawings and have coordinated our work and produced coordination drawings.

THere is an area that was missed where there are (3) fixtures going but there are EXISTING conduits in the way. It's (4) 2" conduits. This should have been caught upfront but it wasn't.

I assume it's out responsibility to show these existing conduits on our drawings, correct?
Would a CAD designer need to see this in person to have this transferred to the drawings or could pictures be enough?

Any additional info would be helpful. Just trying to keep GC honest.
 
But after the fact of finding these now is it the electrical contractors responsibility to now show these existing conduits on drawing , or the architect? I guess if we oh coordination drawings and we missed seeing them it is our responsibility?

You can and should show it on your "coordination plan." It's not your call to disposition what to do with it without further direction unless the plans specifically say you need to. Show them in conflict with the proposed lights, then point to the conflict as a matter that needs to be coordinated before installation can proceed. This will get the decision-maker's attention.

Generally speaking, it's the Architect who should have noted a conduit and identified what to do if it is in conflict with their lighting design. Many EC's will install the light fixture per plan, then when someone asks why they did it "It's on the plans." IMHO, this is in bad faith, but a valid path. The problem with this approach is they spent labor installing it, and now someone has to pay to uninstall it and reinstall it. Hence the bad faith argument.

A more proactive approach-If it physically cannot be done because of the conduits, ask the GC what to do (via an RFI-Request for Information). Keep RFI simple is best: (1) there are existing conduits not shown on plans (2) they are in conflict with proposed light fixtures (3) Plans do not disposition modifications to conduits and (4) moving of light fixtures will change photometry. Attach the plan sheet in question, take a picture and attach it. Then make a suggestion that will be cost-neutral if you can, and request approval from the Owner/Architect before proceeding.

They will likely send the RFI to the Owner/Architect who will then disposition what their intent is and provide direction, or use any catch-all weasel words in the plans to make it the GC's problem, who will then make it your problem. If it isn't in your contract with the GC, state so and see what happens.

You can find RFI templates online by searching Google.

Good luck
