(sub) flooring options

I am in the process of reno'ing my basement.
I have bare concrete floor right now, and it's not perfectly level - few cracks here and there etc.

the framing is all up, but no insulation or drywall yet.

What are my options for the flooring? and when should I start on the subfloor? I plan to have the luxury vinyl planks as the finished surface

Is it just perimeter wall framing up? Is the framing properly insulated from the concrete floor? I would have thought to do the full subfloor first, then frame walls on top of that.

Loads of options for subfloor. Cracks are less an issue than 'not perfectly level'. What does that mean? Large 1" drops from area to area? Total of 1" slope from one end of the basement to the other?

Your basement never gets wet, right? You've had the house for a few years and it's perfectly dry?

It did get 12 months ago. it had minor flooding due to outside drainage being blocked so after a rainstorm water came in through the window.

This is the reason for the reno in the first place. But it's been perfectly dry for 12 months (drainage problems were fixed)

framing is just perimeter and one central partition. There is a moisture barrier between concrete and base plates

Dricore or something similar (supply your own membrane and OSB)

+1

If the floor is flat - i.e. while not necessarily perfectly level, it is smooth from one end to the other, get dricore panels and start laying them down.

Pull permits for the electrical etc - not sure what you need for simple interior framing, but for electrical, plumbing etc. get your permits and inspections done.

Then drywall etc, then flooring last. Get all your taping, mudding, paint done, then flooring, then final trim like door casement and baseboards etc.

How much height do you have?
If you have a lot. I'd just get 1 or 2" XPS and lay OSB on top.
If you don't you can look at using Delta-FL, DMX OneStep and OSB on top.

Dri-core is pricey (The other options are not much cheaper but it can be faster). Here's something to consider. You may not have the room to bring down large sheets of OSB and or Membrane rolls. So Dri-core can make that easier.

If you Can easily bring it down It'll be super fast to do with OSB sheets. Dri-core is 2'x2' that takes time to layout square. With sheets of OSB and membrane you're covering 4'x8' very quickly.
