Ofcourse there is no "admech" per sé, as each forgeworld has their own ways of doing stuff.
I imagine a forgeworld that has been on the frontline for centuries* would have rituals and procedures focusing on time and production output, while some backwater FW would take a more slow and esoteric aproach.
* there was this sweet lil' piece in the HH epic rulebook about titans going into battle, straight from the asembly line, their holy ungents and paint still being wet.
