Default Duct Bank Spacing

I have 9 Ducts coming into an electrical room for a switch gear. There's two 4" for communication coming in and it's close to the main 600v 4"s. Anyone know about spacing between the power and communication ducts? There will be concrete in between but I'm wondering what the minimum should be.
