If the lights you're getting can be on one circuit (one transformer) and still be individually controlled by IntelliCenter, that is fantastic. That allows for any combo of lights you might want. But I would still home-run all the fixtures separately, just so the wires are in place underground should you ever switch to some other lighting system someday.
Each light will have its own junction box near it (typically 5-10 feet away, in the landscaping somewhere). This is where the tail of the light is connected to the wires running back to the pad. 120V lights will be one configuration of wires (green, white, black) and low voltage will be some other configuration. I would have wires run from the junction box to the pad so that you can have any type of light, and each run separately to the pad. Wire and conduit are relatively cheap compared to trying to add new wires later, or conduit (which is impossible after the concrete deck goes down). Have a conversation with the builder or directly with the electrician to discuss this possibility. They can advise what is possible.
All I'm suggesting is that you pay a little extra now to have all your options available in the future. Otherwise, you could end up with whatever the electrician feels like doing (typically to minimize his labor and maximize his profit), which will likely work well enough now, but could leave you wanting some day.
I'm projecting, mostly. I have one light, pointing directly at my house and where we sit at night. It's annoying. It's a single 120V 15A GFI circuit, which is fine for the one high-voltage light. But when I moved in, I added home automation circuitry that utilizes that one circuit to run a half dozen other things (fountain, bug zapper, garden lights, bistro lights, etc), all off that one circuit, which sometimes trips when everything is running at once. It would have been so cheap to make the circuit 20 amps, or to run a few extra wires in the conduit, to give me more circuits, more possibilities and flexibility. But now I'm stuck with one I've got.
Think ahead about things you might not even know you'll want. Speaking of which, while the ground is dug up, you can run extra conduit around your yard for other things. I gave you my list (garden lights, etc). Now's the time. You could run some extra drip irrigation circuits. You could run water for extra hose bibs. Boy, what I would give to have a couple hose bibs on the other side of my pool. You could even run some extra empty conduits that surface behind your pool, for who knows what. Later you could pull wires for outdoor speakers, WiFi extenders, video surveillance, and an extra outdoor 120V outlet or two.
Now's the time.
