Anybody have experience converting street lights to LED?

[sfav8r]

We have been asked to bid on a job to remove the existing street light heads and replace with LED heads. It is a simple operation. Essentially, go up in bucket truck, loosen four clamp bolts, slide old head off, unplug connector, plug in new light, slide over pole, tighten bolts, snap on cover, and place hand over light sensor to test. Then lower bucket and off the the next pole. This would be a two-man crew. I am trying to figure how many fixtures per hour. The number that is being tossed around, is to me extremely optimistic (will share after seeing replies). I think their number is ignoring things like unboxing new fixture, placing old fixture in the box and loading/unloading truck. Having to stop at traffic lights, vehicles being in the way, etc.

It would be great to hear from someone who has actually done this and know from experience, or has done something similar.

Thanks

You may want look into the safety requirements if your working on the highway you will have to provide safety which will need to meet the MUTCD, or other state of region standards. I work for the DOT so I can tell you that the guys will do these fast once they find thier groove, you will want to hold onto or secure those wires once the fixture is off, they tend to want to side down the pole.

Thanks for the tip about grabbing the wires. There is already an approved traffic plan. I'm just concerned about the Master Contract holder who insists that the productivity should be 120 fixtures per day for a 4 man crew. That's 8 minutes per fixture. What about red lights, trees in the way and a million other variables.

I was hoping there was some kind of standard time like there is for roping a house etc.

I really can?t help with that as we aren?t in business, you should contact NECA I?m sure they have labor units available for replacing cobra head fixtures, I know from experience that our guys can do them pretty fast, 8 min is probably about right, however that largely depends on a number of factors and we aren?t doing 120 a day, that?s a lot of material to handle. I find that we spend more time with safety than the fixture replacement, so if you?re responsible for setting out the safety that is going to slow you down. Your right to be concerned about the other variables as working on the highway there can be many.

Let me guess...

I bet the people throwing around the numbers don't actually work out in the field?

I hate the desk jockeys that claim certain tasks should be able to be done in X amount of time. Sure, in ideal conditions it may be true, but ideal conditions are few and far between.

It's ''plan for the worst and hope for the best", not the other way around.

Run from this, there is no way you can make 8 minutes a fixture, not a chance in hell.

As you mentioned there is unpacking the fixtures, disposing of the old fixtures and trash, fueling the truck, and you likely take a couple of coffee breaks during an 8 hour shift.

Absolutely all tasks related to the job must be rolled into the time per fixture. In my opinion 8 minutes is a joke.

I would be a lot closer to 60 minutes per fixture than 8.
