Another idea how to take down the Leviathan:
Build a battery of Rechargers (you need them anyway to withstand the intensive attacks of the later game and Hidra bombardment), step forward with your SCV and just snipe it! Just stay within their heal-radius and set them to auto-healing with the right click on the icon in their menu.
One snipe shot deals 25 damage.
Leviathan has 2000 of a health.
So, it takes 80 shots to kill it. Or 16 full charges.
Not that much. Even that some charges will happen before the SCV runs out of energy, still it stays within reasonable limits even if it takes double number of charges.
This happens faster, than with a single Bertha.
