You don’t need to load constants anywhere, they’re automatically autoloaded by CI itself, that is the point of them. To use them keep in mind they are constants and not a variable as you’re used to with the $. So in your case after defining them, anywhere in your application you could for example use:

if($user->userType == SuperAdmin)
{
   do something here;
}

Note that the SuperAdmin is written without a $ preceding it and not inside quotes. Again, after defining them in the constants file you need to do nothing else to begin using them in your application.
