Look up `Children of Orc.'
The player can give assignments to the other Orcs, and the action plans for those assignments are displayed in-game. The Orcs are smart enough to find cheap plans. When tasked with procuring stone, e.g. they will see what the quickest way is. Sometimes scavenging for discarded stone may be cheaper, other times, with pickaxe in hand near a quarry, quarrying is the way to go of course. They adapt. But whatever plan they come up with, it is communicated to the player in an info-window.
