Good depth for an underground bunker?

[Yung Ducky]

So yeah ive been hacking and hammering away at stone and applying wood frames for a stair case (probably not the most cost effecient entrance to an underground base) to an underground base. Ive gotten pretty far down into the earth to the point its silent and i cant hear any noises from above (Ex:Birds/Wind/Trees). Even though im this far into the earth my elevation is still +77 so i think i still have a ways to go . Im somewhere around 20 blocks down into the earth at this point, should I keep going?

keep going

20 is a good start but yeah definitely keep going. I wouldn't call it safe until you're at least 40.
And even with that, I wouldn't put forges or campfires until you're bumping bedrock.

Alright i've dug down to a point where on the surface, my elevation is 92m, and ive made a reinforced steel staircase leading down into 39m elevation. Im currently making a little landing area which Im thinking of just turning into a straight down ladder shaft until i reach like elevation 0 or -10. Would I be safe then considering the ammount of distance from 0m or -10m elevation to 92m?

[Armae Delilah]

if the surface is flat then i'd say you're rather safe, just use cation when runnning your forge(s) or campfire(s) for too long. if the surface is sloped, then i'd say keep going deeper, especialy in the direction opposite of the slope.

Im in some type of plains environment where everything is kind of dried grass, trees are dead, and the highest hill is only like 7m so no slopes to worry about really, I mean with this ladder shaft ive branched from the staircase I could possibly make it to bedrock? I dont know how much farther that is though is the thing

Did you do all that just with an Iron Shovel? :O

In my current game I dug down to 50M elevation. I have 3 Forges running 24/7 and much Campfire activity and have had no problems with zombies.

No that is fine. Zombies never dig deep.
However, a staircase seems to be a design fault. If they crack the door open....they got a nice pleasant walk right down to you.

Consider putting in some "motes" with spikes, or better yet, just build a mine shaft with a ladder in it, somewere deep make a door on the opposite wall to the ladder and build your bunker behind it. -No visitors :)

Yeah, I did , that and a pickaxe, I was about to use an auger but i decided not to draw unncesesary attention to myself while being vulnerable in an unfinished base. Took forever, but i just listened to music while doing it so it wouldnt be as much of a drag.

Well the way I have it set up so far is, its a staircase leading down to about 32m above 0, then its a landing area with another 100% upgraded vault door and a soon to be upgraded vault hatch, which then leads down a ladder to bedrock (have yet to actually reach bedrock lol) which will then lead to another landing/doorway area which will then actually be the base which Im not even close to starting on yet. The thing is though, I was thinking, what if I set up some sort of easy to hear alarm system for zeds, like for instance have a mine every few feet or so that whenever a horde comes through, if I hear an explosion Ill rush to the surface to keep them from bashing open the front door to the vault. Dont really know yet though, havent put it through any stress, i guess I might put a simple pit infront of the door to catch any zeds if they do manage to make it down that deep, given they dont die from the ladder fall lol.

The mine alarm idé was good :)
Considering your layout, maybe they will just get lost in the pathfinding?

I usually build my base about 8 tiles up from bedrock. I got the forges going around the clock.
So I think that my heat signature should be really high.

Zombies usually wreck everything on the surface, but seldom come down to me.

I dont think that your surface base can resist the 7 day invasion. But I am curious to see if the zeds creep down to your door. Could you do a update when they invade?

Yeah definately will, I have had one screamer zombie creep up from the surrounding trees I have growing, scared the sh*t out of me lol, it spotted me but suprisingly after i pumped a shell into its face, nothing came after that. Im currently working on the main doorway to the actual bunker part, havent even finished that though, havent to get ALOT of concrete. Speaking of which, is it better to use concrete on upgraded wooden frames or use rebar/wood and concrete?

Well, I myself usually use an aboundance of reinforced concrete block.
They seems to be the best buildingblock considered the cost.

When I get my 4 forges up an running and go digging out my bunker, I never run out of raw materials for it. At the moment I got about 10 0000 concretemix and 2500 rebarblocks just in inventory and I have just begun to basebuild.

The digging automaticly gives a lot of raw materials and coal fuel for the forges.
It seems easier/cheaper to go that route than the woodframe one.

In the mine one can basicly work undisturbed, whilst out shopping down trees a closespawn zed or the tree can kill you suddenly. Also surface activity tends to create hoardes much faster.

Also if you go the "mine-material-route" you prabably lvl up faster beacuse the constant making of gravel and mixes. I am not sure, but it seems so.

I did consider going the metalblock route, beacuse it seems to be the sturdiest one but it is all to expensive and it makes my bunker look depressingly dark&gloomy.

I built my first base (First in A13 I mean) underground, about 20 blocks deep and regretted it. Zeds spawned constantly on top of my base, getting in and out was a nightmare excercise, and I was constantly making new ceilings, hatches etc. I think unless you are really deep (in which cae going in and out becomes a major PITA itself as it takes too long) its not worth it. I normally make a tunnel away from my base, rather than have the hatch directly above the base, or a door in the wall to walk in and out of) but the above case I didn't, and I paid the price. In fact I'm still shuttling stuff from my old underground base, right now, and that really IS a pain in the aspirin. Granted its only coal and Potasium, but I have a LOT of it and I'm not giving it up.
Trial and error is how I've spent this past 2 years or so, and nothing has really changed in that regard, and every time I think I have base building figured out, something proves me wrong. Good luck in any case.

I usually go down to the bedrock, its not really that far down. And typically I just have a single shaft with a ladder going down, stairs would take for ever really.
