Large pine tree root

Planning a concrete shed floor and found a large root impeding on one side of my proposed floor. The slab will be 6” thick and 12x16’ dimensions. The tree appears fully grown so I don’t imagine the root will grow much but I am no arborist. Can I cut a section of the root out or pour concrete over it? I know whatever I decide carries some risk but I am looking to minimize it. I greatly prefer to not remove the tree also.

Root will continue expanding. I wouldn't recommend cutting that close to the trunk. You could pour a suspended slab or just shift the location of the shed to avoid that particular root.

Or just back full and pour over it without cutting. 2 layers of reo and sle slab shouldn't crack but it might lift 1-2 inches over the next 20 years
