Construction Worker's return

[Kotlol]

The major problem with the construction worker is that it took half of the engineer's job away from them by creating a specific other job for doing it.

Engineers ARE construction personnel. You should focus on making construction more fun for them

Okay I didn't know that part. I always figured they were that, but most stay in the engine room... So let's just add the tools of construction to them insted.
Just like Doctors can go Pharmacy, surgery and basic treatment basic. To nurses and EMTs.... why not Engineers as well?

"Sub classes without being sub classes" 
So you got Engineer (Engine), engineer (maintance), Engineer (consturction) ,firefighter and such. 
Just have the kits in engineering somewhere in closets of engineering.
Now we get more engineers actually willing to pick their job insted of mechanists who buy the kit from cargo and then build with it.
