Giving a quote for a string of lights....How long do you think it will take?....

20 to 24ft ceiling, highly congested, genie lift supplied.....probably 25% is clear and rest is congested with production machinery but reachable with alot of lift movement.

50ft home run, 2 transitions

200ft straight run with 6 High bay T5 fixtures, using whips and 4x4 box's, Hubbel TW recepts and plugs.

277v, 3/4emt, hung on red iron, and Zchannel. beam clamps and miny's, Jack chain

Just curious what you guys think, and I'll compare.

I would guesstimate 2 men, 60 to 70 hours. Only because of the congestion and non-moveable machinery in the way. If it were wide open it would go a lot quicker (but you already know that :smile:).

1x16 raceway
2x8 pulling wire and landing recepts
1x6 prep'n fxtrs
1x6 hang fxtrs

ttl 44hrs x 1.25 contengincy=55 plus 4hrs planning and procurement, tool up etch.....ttl 59hrs...

Without knowing exactly how the buiding lays out I would probably want to give myself a little more time ,back when we did alot of factory work it always took alot of time just getting into position .I have found that things always go faster in my mind.

You know I missed this....should be more like 8hrs....So....63hrs.......MORE? material cost is $2975 which includes a few items not mentioned on this portion, but pretty close....

Maybe I'm reading this wrong.

Your hanging (6) t-5's, running 200' of pipe? That's it?

I'd probably scrap the lift idea in most of the place then, and use extension ladders.

24-30 Mhrs

I dont think you read the first post, about the working height.....:smile:

Bidding around $5000 for the whole job? What about the existing lights...will you have to remove them?

$5000? I dont think so, can I get you to do it for that? I'll stay home.:grin:.....and this is new string, if it were replacement, the conduit woudl have already been run.

I saw it, hence the extension ladders.

I also assume by string of lights, you actually mean all in a row, approx 15'-17' apart, and not scattered in different places.

You've got to be way younger, and have better feet than I do....I'll take the lift. Besides its furnished as stated....:)

And yes it also states in the first post about being a straight run.....:)

I agree, hanging high bay fixtures useing an extension ladder is a good way to get someone hurt and not worth it. Even when you have to rent a lift you can do twice as much work with less effort so it's still worth it.

On the amount of time necessary for the job. Mule is the only person that's actually seen the job so his idea of the time need is probably more accurate than anyone just reading about it.

If someone were to call and want a price on this job I wouldn't give one without looking the situation over and there is a reason for this.

How is this any more dangerous from working off an extension ladder while doing a service change, or anything else for that matter?

I agree, a lift is alot easier and faster, if there is open space around. However, you fill a place 75% full of stuff, the issue about the lift being faster is muted. Most of the time, with a full space, lifts are more trouble than what they are worth. You have to constantly stop and get someone to approve you moving something, you have to wait for someone to get done with something before you can move it......ect.

I've done a couple of these, and moving extension ladders is wayyyyyy quicker and easier than using a lift in these spots.

But like you said, Mule is the only one who has seen this.

Dnkldorf,

are you talking about a scissor or boom lift? I have had great luck with one of these in tight quarters running pipe in a ceiling:
http://genielift.com/zb-series/zb-z30n.asp They articulate in so many places you can practically thread the manbasket like a needle around process piping, ductwork, etc. I've been able to reach some pretty gnarly spots with one of these. The boom doesn't stick out so there are no worries about clearing a space for tailswing. Plus it has a 21' horizontal reach, that's 42' of equipment you can boom over if you can get around both sides. I have a hard time believing any extension ladder setup would be faster(not even mentioning easier) than this.

Cow, I think Mule meant a standard scissor lift, so I did as well.



Bob, two guys on ladders hanging tandem 6 bulb highbays with jack chain, can go pretty quick if their prepped before there hung.

Or it can take all day, depending on the people.

No?
