need help

[voltage37]

I have a fire station to bid. The building is steel and about 5,620 square ft. The truck bays are going to be lighted with 400 watt mh lights. All wiring will be surfaced mounted in EMT conduet. Can someone tell me about what to charge an opening for conduet? Thanks

Just based upon my experience, you're looking at a $30,000 electrical job.
Chances are the light fixtures are spec. So be sure to get with your local representative
Also check if an "equal to " is allowed for the fixtures.

IF you use MH fixtures put in an adder for quartz restrike.

If you can spec fluorescent, there are some 6 tube fixtures that are lumen level equiv to 1 400MH. These can be put on an emergency generator easily.

IF you use MH fixtures put in an adder for quartz restrikeWhat do you mean by this? Thanks Jason

HID (high intensity discharge) fixtures like MH (Metal Halide), MV (Mercury Vapor) and HPS (High Pressure Sodium) do not re-light right away if the power is interrupted.

A Re strike lamp provides light while the HID lamp cools and re strikes (re-lights).

If you are using HID fixtures as emergency egress lighting the re-strikes or some other means to maintain lighting are required by 700.16

In an installation like a fire station the re strikes sound like a good idea.

Thanks for the info. I did plan on a quartz re strike light.

I suggest doing a full take-off: count every type of device measure all the runs, collect quotes for your power, lighting & systems. Build you estimate from the drawings including the specifications, as it is actually drawn as well as it will be installed.
The only safe way to use average unit type values is with your own data. In most cases competitive estimates require accurate take-offs. If you are doing a design build project unit pricing can work.

I don't price by SF. I do a take off of all openings and extras. Have not done that type of work but I can tell you what RS Means says.

5.75/sf on the bottom 1/4 ($32,315)
11.55/sf in the middle range ($64,911)
13.05/sf in the top 3/4 of the range ($73,341)

There are +/- adjustments for location. Means tends to seem high to me. In our area for goverment work they seem to go fo high prices with countless demands of the EC to justify it. It's not their money.
