"wire suspended" recessed lights?

[switchleg45]

Plans specify that recessed fixtures in open commercial ceiling to be "wire suspended @ 12'-0" AFF from roof structure at open ceiling locations"
??...strut?...any other methods you guys have utilized?
For randomly spaced fixtures I can't imagine a wire at each leg of fixture.
Any ideas would be greatly appreciated.

12 AWG steel ceiling tie wire, I would come down with one and connect it opposite corners with a second piece of tie wire.

Oh wait, you said open,.... sorry.

I would probably look into a cable hanger set up.

Using aerial? cable is definately a time saver compared to using jack chain or equivalent.

There is no ceiling grid...they are to be mounted out in mid air at 12'...?

Plus, check the load rating on your jack chain... it often ain't much

I checked out the Erico speed link...?..they are to be mounted at 12' AFF...right out in mid air! I think some type of T-grid or strut would have to be supported first...to keep them from swinging.

I was in a new place friday night that had high open ceilings blacked out. They had hanging strut from cable , with various fixture types mounted on the strut. Looked good!

I would not volunteer to provide anything more then the prints show. It sounds like an RFI to the designer is in order.

Many of the jobs I have worked I was required to send an RFI (Request For Information) to ask the engineer or designer questions.

If you not familiar with that process you're lucky. Pick up the phone call the person who drew the plans and ask 'Hey, what exactly did you have in mind?'

Here is an example of an RFI I found on the web.
