I've always thought NECA's labor units for installing a transformer( you have to combine the labor sections for the unload, inspect , labor & install & connect) were extremely high. We go in much lower. What do you think?

Maybe those figures include labor for a forklift certified operator to move it into place, time to track him/eqpt down, maybe a minimum 2 hours for that. Time spent waiting between once you know the delivery truck is on site and time to get said forklift/operator. Unpackaging/inspection, discarding trash. For installs, time to notify/schedule shutdown for installation. LOTO of eqpt. Calculating feeder size, installing wire and conduit to and from unit. Verifying phase rotation. Measuring primary and secondary amperage and voltage. Grounding and bonding. IR readings. Any applied field warning stickers. Marking unit to site plan designations via stickers or stencil/spraypaint. Concrete pads or wall/ceiling mount.

I dunno how much of that ^ is figured in their numbers
 
I installed a 37.5 kVA transformer the other week. 3 phase. It took me and another guy 4 hours. So 8 hours total.

Did you supply the transformer or was it waiting in place for you? Did you pull the permits? Did you do the drawings? Will you do the as-builts? Is inspection time included? Is there a commissioning process?

Just a short list off the top of my head.
 
We got a 45kVA 3ph outdoor yesterday. 1 man-hr to unload/inspect for damage, another 1hr (30 min for 2 people) to move into shed (for security) until installed. Probably 15 minutes minimum to gets tools to unbolt from palette, another 15 to do it. 15-30 min to throw away/recycle packing. 3 of 10 hrs for unpacking/inspection. But if this thing had to be carted 400' up 70 floors of elevator, I could see 10+ man hours getting burnt in a heartbeat. Moving a 375lb xfmr with two people is not easy lol (forklift is too big to get to the pad unless fencing and other obstructions are taken down/cleared). Will let you know how long it takes to set this on the pad (that we formed, poured, and screeded ourselves).

At the WWTP I worked at, maintenance would have moved the xfmr in place and unbolted from the palette. Not saying the electrical would be a cakewalk by any means, just that much of the gruntwork would be done.
