Default Adding a ceiling light in a highrise apartmentent

Hi guys I have never done it so I was wondering how to run a wire for a light in a bedroom. I never work on a highrise so I dont know if all is concrete or there is a gap between the ceiling and the concrete. Any idea?? Thanks

Caution 1. Don't drill thru a pre-stress cable in the pour.

Caution 2. Don't drill thru a conduit for the floor above in the ceiling.


Neither is supposed to be close to the surface but they are there. You know that funny straight rod that attaches to your hammer drill? The one that you can use for a depth guide? That one? Take my advice and use it. Use 1-1/4" tap cons at most in length and set the depth rod on your drill to that depth and keep to it.

Also a really good laser tool is a the bomb, the ones that throw a cross up on the ceiling that self level. Nothing worse than a crooked run of wire mold to stare at when you look up at it.

I get these jobs sometimes and I end up doing twenty or more apartments in one building with three or four lights or ceiling fans per unit.

Make sure you get permission from condo corp. Once that concrete drilling starts they will come knocking.

many of the buildings Ive been involved with have two ceilings: the structural fire rated concrete or wood then the lower metal stud or hat channel constructed condo ceiling.

I just installed additional ceiling light from another light and there was 2' high space.

I put a skylight in once in a highrise. It really pissed off the people upstairs.

Depends. Is it poured concrete solid or pre-cast planking? Is there rock over the concrete?

Pre-cast has 4-6 elliptical voids running the entire length of the sections running lengthwise.

There are many ways to run the cable and JB’s after the fact. What does the customer want and how much are they willing to spend? Wire mold is the cheapest and least aesthetic and channeling is the most but will be hidden as if it was done in the original pour.

Oh my least favorites is the swag light running off an outlet.
