Help bidding a warehouse lighting repair job

Not only measure the difference in the brightness of the lights, you should document the consistency of the new lights (as fluorescents age, their color changes). Other metrics that should be recorded are the amp draw reduction in the lighting panels, as well as the temperature drop.

This is a factory I swapped out for LEDs. You can see the difference in both the brightness as well as the consistency of the new LEDs. The old mercury-vapors had colors all over the place.

The amperage used by the new lights dropped by 80.9 amps, and the temperature in the lighting panels dropped 21°F!

Important note: Unless you're truly familiar with shooting bracketed RAW photographs in full manual mode and editing them to the same white balance, it's hard to truly document a side-by-side image like this. These are not just cell phone photos.
This warehouse looked like the lights were off when I was doing the consultation. Hopefully I get this project. It will be good experience for me. I submitted a quote of $17,000 + $125 per hour for troubleshooting fixtures that don't have power present. It will probably take me a little over a week to get it all done with the troubleshooting.

You probably got some employee mad by adding all that light and getting rid of all the shadows, no place to hide for a nap. Lol
But seriously, NICE. I've had customers amazed by the difference in both color saturation and brightness given by these lighting changes. Even had comments that QC improved with the better lighting.
 
I'm going to need to rent a scissor loft for this job.

The warehouse is full of stuff because it's a logistics company so I'll be waiting for people to move stuff to get access to lights.
Did you consider an articulating lift? I know they cost more to rent than a scissor lift, but you won't have to wait for access and be dependant on the customer to move stuff, that can mean a lot.

I actually only added two lights... both directly over work stations that ended up in a 'dead' zone.

My findings as well. Generally this change of lighting almost more effective than adding lights in getting floor coverage with no shadow. I wish I knew how the LED gets so much more light with much less shadow. Replaced 20 troughers with LED flat panels, had shadows all over with the fluorescents but with the LEDs placed in same locations and equivalent ratings, and could walk through with no shadow being cast. And before someone says it, the lights were on, and no I'm not a vampire.
 
On shadows-
my guess is that troffers, esp without a good diffuser, are close to point sources (or line, if you prefer), so those points cast defined shadows. LED panels with what could be 100's of LEDs and better diffusion still cast shadows but many more and fuzzier shadows.

The last change-out I did (December/January) we ended up putting in only half the lights. It was a warehouse, so task lighting wasn't an issue. All the LEDs had programmable motion sensors on them so as I was swapping them out, it actually got darker. With only one dispatcher in the office, and two forklift drivers that usually were around the docks, most of the place was dark.
 
I would.
And I would probably order an extra 6 or 8 tubes.
And I would be enough to account for anyting defective or if you get something with funny CCT

Make sure you get through the job seamlessly.
At least get one case quantity of extras, presuming that it is in the 16-25 range.

Next comes lamp sockets- are they all good?

Depending on circumstances might be better to just go with newer design LED luminaires. Can possibly leave existing working as you install the new then transfer to new at the end or in sections at a time.

Can offer to do for less if you don't have to remove/dispose of old luminaires. If they are renting the space they likely don't care and might just do that. At same time if renting the owner should possibly be involved here.
 
Never do the work for a tenant. Always work directly with the owner.

If you don't the tenant will say they're not responsible for the work, and the owner will say they never approved it be done.

That can vary, but yes you need to consider who is responsible for paying.

In CA you can still place a lien unless the owner files something called a notice of non responsibility and even that has to be done a certain way to be enforceable.

AFAIK even with the lien the owner could still lease to someone else. They just can't easily get transfer of deed (sell it) if there is still liens on it.

Once you have the lien on the place you can foreclose on the property to force a sale and get paid. Generally as soon as that paperwork is filed someone pays. If there is a mortgage on the building the lender will pay to preserve their interest.

Maybe but probably not as simple as you make it sound. I doubt it is worth going through the foreclosure process on a million dollar property if I am only holding say a couple thousand against it in liens. Having the lien still means they can't give clear title to a buyer and that lien will likely be cleared up in some way before the new buyer takes title whether it be direct payment of lien amount or via the court system. Only lien I ever filed myself - the property went through bankruptcy. Since I was a creditor in the case I was kept informed of the court actions, there were many other contractors and equipment suppliers on the creditor list, but the attorneys and banks got all of any money that was available and the rest of us had our liens discharged by the court.

And the property went to the bank, with no liens against it.

All good points. I should have been more clear, usually a valid threat of forcing a sale is enough to get someone to cough up a check -especially when its a smaller amount of money.
 
A lien makes it somewhat easier to get court judgement against that party (if its worth enough to bother), but then you have to collect the judgement.

And, of course, all this varies state-to-state and sometimes county-to-county.

Been down that road before as well. Filed a small claims court case once, other party didn't even show up. Got my judgement but it was still up to me to collect it - total waste of time for me and for no more than the claim was. Some businesses pursue nearly all debts "just because". I learned there is a certain limit before it is even financially worth the effort when you otherwise could have spent that time working for someone that does pay their bills.
