I have tried to start new maps a few times and just cant get any science labs to generate. I have tried about 5-6 times to make a new character and reveal the map and when there is no lab I delete all saves and worlds so that a new can generate.
Please help me 
There are labs there’s more to your maps than what you initially see or even using reveal all in the debug menu.
It should also be noted that if you are using the Classic Zombies Only mode, labs will not spawn.
At all.
Ever.
