It will have 38 layin troffers, 6 - 4' strips, 3 - recessed lights, 11 - emergency lights, 2 - 60amp hvac, 2 - 20amp water heaters, 5 - bath fans, 50 - receptacles, 16 - phone roughin boxes, 9 - occupancy sensors, 2 - panels / 3 - phase 30space plugins, 2 - phone services.
Things that might have been missed or unaccounted for (or unknown):
NO RESPONSE IS REQUIRED BY You PUBLICLY to the following list:
New or existing building? Is it a free standing building, if not are there rated fire walls requiring special fire mating on some boxes. Is there a gysum ceiling above
the lay-in ceiling?
No mention of F/A? Is a circuit required?
F/A in most cases can be a stubbed pipe out of a hard box and plaster ring to above ceiling. ~ equaling - two bundles of 10’.
I’ll assume lay-in ceiling, so rod ceiling attachment for lay-in lights+ all other things in the ceiling.
74+6+22=102x 2 per light = 204 connections @ 10(minutes)/per light= 2040 c.m.
2040 conn. minutes/ 60 minutes-hr = 34 hours of strapping.
Of course it just dependson the AHJ. A buildin code issue around here.
No egress outside lighting over door-outside, city ordiance here, no outside lights or spot lights?
What type of emergency lights, all bug eyes or 2 x 4 with emergency ballasts?
Or are all just directional exit signs or combinations, exit and bug? No lighting contact to turn off all lights, just a consideration for the green moment!
HVAC: disconnects; fused and flex fittings, who’s making and paying for roof penetrations. (more conduit), means of disconnect for both services - 4 total
Is there a Heat strip and does this require any special considerations?
H2O water heater(s). : (2?) Local disconnects, if placed above ceiling?
No H2O cooler listed - GFCI required, usually new ADA style that’s inside the machine per design. Get a cut sheet from the Plumber/Arch.
Break room / Kitchenette / Wet Bar - GFCI usually installed
Additional circuit for large refrigerator?
One more additional circuit for toasters, microwave, under cabinet lighting?
50 receptacles - no mention of copy room/ copier printer - fax, entrance greater area/secretary pool, mop/closet room. All might need more circuits or electrical considerations. Bathroom getting a air hand dryer or paper towels. Lately been seeing no GFCI in Public Bathrooms.
All assume that the job is calling for all conduit but the job will be done with MC?
Phone drops all need conduit up to at least above ceiling, tie down exact amount of telephone drop circuit per drop telephone and another Cat-5, 6. Granted job is usually farmed out but it is part of your bid to sub it ? Tie down exact face plate for telephone jacks with two phone service and exact conduit and box size?
4-11/16 and 1" conduit is ususall in this area.
You account for all the straping of conduits, mud rings, total count of boxs, various wire nuts, various size boxes(add a few 4-11/16 in the correct places)?
No TV’s, no conference room considerations. Telephone jack in kitchen or copy room, (both might be extra’s).
Did they design a nice electrical space and note the telephone demark? Existing or not, probably not.
Wheres the source of power, anything special for you to consider there?
I didn’t have anything better to do so I thought I'd break down my thoughts on your list…
