Welcome to Happyland... which is also a hellhole...
This is my 2nd prison. I aimed for a capacity of 1000 inmates. Made a lot of mistakes, learned a lot & spent way too many hours on it :)
Upper left is for min- and med prisoners. I started with dormitory's but gave up after too many tunnels & riots in them. I still like dorm's but for max 4 prisoners. The main reason for this block is to have as much prisoners working the workshops as possible.
Upper right started initially for the family cells & nursery. I've added Protected Custody (since mom's hardly ever cause any trouble) and added minor sec's to do the jobs on that part (cleaning, cooking, laundry). This works pretty well. No need to keep the PC's fully separated.
Lower left, the biggest chunk, is max sec. I think those blocks are too big to keep fully under control. Initially this were also 2 big canteens...until the gangs kept fighting over there. I've removed the canteen room from the strip in the middle separating them into essentially 4 canteens. This seems to work but still not perfect. Also continuously assigning gang bangers to their own blocks ("you gotta keep 'm separated") is tedious... Would be nice if I could assign a gang to a block so the game assigns gang members to their dedicated blocks.
Lower right: Super Max. I've been playing with designs I found in this sub. Regular super max prisoners can be mixed and have group canteens / yards. It's the gang members & volatiles which are ... a pain. For space purposes I keep them by 2 or 4 with their private canteens/yards and the worst of the worst in their own. Still causing troubles but more manageable.
I also made a note to give the security room it's own dedicated powers supply and I've added sprinklers to all power supply's but have to make sure they're connected to 2 water supplies (in case the nearest gets disconnected due to a power surge). That prevents a lot of damage.
Despite my best efforts & lot's of free time I still have daily riots in all sectors (except upper right). The danger level just never goes down... I think that's the result of too many max & supermax & gang members
Roast me!
