Linux and Unix security are enforced by the kernel. You can make a simple settings change to allow admin to run as root. Since doing so is incredibly dangerous to your server I won't recommend it.
Nor will I tell you how to do it, because if you search for yourself on how to give the admin user root privileges hopefully you'll also find many discourses on just how unwise it is
By writing the use of sudo into scripts you can probably create your own scripts to do what you want as admin; I don't recommend this either, as I think it's quite insecure as well.
