2365 level 3 design cafe and basement pool

[PostMelon]

Hi,

I’m currently doing my level 3 design but no where in the spec does it say how thick the cafe floor/ basement ceiling is to drill through for my cables, current measuring my routes and unsure how much to leave for each light and switch and how much to leave for the drop through the floor from the d/b.

Be grateful for any advice.

Thank you
