I'm a low voltage (12v - 15v) outdoor lighting installer, and I typically install systems for existing houses. I'm in the process of designing and quoting a large outdoor lighting project for a high-end custom builder who is currently framing a 12,000 sf house. The driveway will be exposed aggregate concrete, and there will be concrete around the pool as well. I want to install small well lights that are flush to the surface of the concrete, which will be used as subtle markers along the edge of the driveway and pool decking, as well as to light the garage door centered on the garage apron. I would typically core drill where I want my fixtures to be, and run my direct burial wire as best I can. I'm trying to think through the logistics of this install prior to the concrete pour. I'm thinking that I should run conduit and somehow stub-up at each fixture location. The housing of the well light is 1.2" wide and 4" deep, while the head that is flush-mounted is 2" in diameter. If I were core drilling, I'd use a bit that is 1-1/4" and go down 5" into the slab, and the wire is 18AWG direct burial. I'm looking for advice that will look professional, both in the finished product and in how I present my company to this builder and concrete contractor he uses. Specifically, what type and size conduit should I use, do I bury the conduit in the gravel, set it between the rebar and vapor barrier, etc., what's the best way to stub it up so I can come back after the pour and easily install/wire the fixtures, etc.? Thanks!
