...On a side note, this contractor also sent an entire catalog of electrical boxes as a submittal. No indication of what they are going to use, just sent a catalog.

Maybe they were saying "this is the manufacturer we buy our boxes from..." and leaving it up to you to figure out they know which ones to use where...

I don't want to sound too harsh but they didn't really follow the directions. You said certain fixtures are A (or B). You said others were to be "pre-approved". They never sought pre-approval.

To me this is Van Halen and the Brown M&M's.
(If you don't know the story, Val Halen always requested M&M's (sans brown ones) be kept backstage. This way David Lee Roth could walk in and easily see whether the promoter could follow directions or whether than had to go out and assess what other things, like electrical supplies, dimensions, and weight limits had been ignored.)

To me it's a red flag that they don't follow directions, they are probably looking to save a buck, and they are not forthcoming and communicative.

Then again I may just be the kind of guy who would trash a dressing room because I found brown M&M's.

Maybe I misunderstand this.
But if the fittings provide equal performance it is a commercial rather than technical issue.
But what do I know.........

I agree with making them sweat and on the fixtures.
On this part




On a side note, this contractor also sent an entire catalog of electrical boxes as a submittal. No indication of what they are going to use, just sent a catalog.
I would "reject and resubmitt" with a note telling them to highlight all boxes intended for use.

"For some of the lights, I just put "other pre-approved equal" for the second manufacturer."
This to me is open for change.

"The shop drawings come in,"
This implied some sort of information was supplied about the or equal.

"For the most part, these fixtures seem to be equal to the fixtures I had specified."
How do you know if you don't have information?

" Normally, when contractors want to use another brand, they will send us cut sheets, and we may or may not approve them as equals by issuing an addendum."
Is that spelled out in your documents?

" There weren't any requests for substitutions made."
Could it have been that the "shop drawings" submitted, equals a request and if more information is needed should be requested? It seems that you did find the manufacture and some spec. on them as you stated " seem to be equal", or was that just they were white 2x2 drop ins.

Trust me I have lost many bids to many "loop holes, out right lazy people, boilerplate spec. that wasn't so plate, etc., not defending the guy but perhaps a phone call/text/Email/post card, sent by the secretary, intern, could have been in order. The "new fixture" could be your new cost saving spec. as lighting has been changing rapidly.
Hell I lost a big bid and was low bidder, reason was that Co. never heard of us; we were new but just completed two large jobs at a major university. Then when his contractor couldn't answer his questions he calls me; I helped out and built good will moved up on their list.

All valid points, and I do like the M&M analogy:)

Sameguy; We do have it spelled out pretty well in the spec, but I do see your point also.


Interesting. I've never considered doing that. It almost makes me chuckle.

I don't think its a first. I've seen some engineers include "Do not send catalogs" in their specs for submittals.

I don't normally even ask for shop drawings on boxes, but there were a couple of things I did want to see on this project.

No, it wasn't left open. Contractors that wished to make substitutions were supposed to provide cut sheets along with a request for the substitution to be approved. That was supposed to happen during bidding, but it didn't.

There is no way to know, but I suspect the difference in price is probably pretty minor. If I asked how much they saved, I'll bet the contractor would say "These were actually more expensive, but I like this supplier because blah blah blah..."



I think that's a pretty good idea, even though bidding is over. At least they would have to admit its a substitution, and maybe even sweat a little. And it would also be a minor pain to the contractor, which Charlie suggested.

On a side note, this contractor also sent an entire catalog of electrical boxes as a submittal. No indication of what they are going to use, just sent a catalog.

I had a contractor try that. I sent it back "revise as noted and resubmit" and told them to mark or highlight each component type and each size they intended to use, and not to send any pages where no items had been selected. Also, our submittal process was after the bid and we allowed "or equal" in the drawing prep stage, but we had to actually approve it.

So we put a small project out for bid. I specified a package with Brand A light fixtures, with some having Brand B equals.

For some of the lights, I just put "other pre-approved equal" for the second manufacturer.

The shop drawings come in, and they are using Brand C, with some other smaller manufacturers for a few of the lights.

For the most part, these fixtures seem to be equal to the fixtures I had specified. Normally, when contractors want to use another brand, they will send us cut sheets, and we may or may not approve them as equals by issuing an addendum. But that didn't happen on this project. There weren't any requests for substitutions made.

So I'm just wondering what others would do. Reject them and tell them they need to use the specified fixtures? Or go ahead and approve these lights since they are pretty much the same thing as specified?

Our front end spec has a lot of detail on substitutions, so I'm sure I can reject them if I want to. But I'm more inclined to let it go. After all, I probably would have approved these if they had asked during bidding. But I wonder if its fair to the owner and/or other bidders to approve these after the contract has been awarded.

Contractor should submit all cut sheets so that the equivalency determination can be made by the reviewer. If the item meets all of the specification requirements, point for point, without even the least been inferiority, I would say that there is no reason not to approve. Here, quality is being equated to price. If the specs match, I would approve it. Though, the field that I work in it is mainly government work so we need to list at least 3 manufacturers and still even then allow for approved equals. We also have a construction support budget when it is approved so things might be different on my end.

Require full cutsheets, direct "consideration" to be offered to owner

Require full cutsheets, direct "consideration" to be offered to owner

Since the legally defined process for getting substitutions pre-approved (which means prior to bid) was ignored by contractor, this is an automatic "Reject."
UNLESS there is some offer of Credit to owner, in which case:
1) Require full cutsheets specifically indicating exactly which models and options are being offered as an equivalent substitute for each fixture.
2) Engineer does not then "approve" the substitution, but rather issues an "opinion" on the equivalency of the fixtures, to the owner's representative.
*This may be the Architect, since it all goes to/through the Architect anyway, but it is "for consideration" of approval, by the owner, of the CREDIT offered.
3) If there is no "legal consideration" offered to the owner by the contractor (and I don't care if it's $1 or $1,000), there is a legal basis for complaint by any of the scheduled lighting fixture suppliers, any other Electrical Contractor, or even the owner after the project is approved and some issue or warranty or problem arises and the legal eagles ask the question "WHO was it that 'approved' this substitution in violation of the contractual documents?"

So by all means, evaluate the cutsheets for equivalency, and mark them "reviewed" and direct the Contractor to submit to owner with an offer of some credit so that everything is clean and above board, and it's the OWNER who is accepting the substitution.

This place could use a "thank" button. Nice post, thanks.
