1BB, we had spoke on the phone some years back when you offered to do these with your equipment. I wouldnt mind shooting you an email with a few questions if you have the time to answer them. I am working on trying to get a few of these put up locally but am highly concerned as to the abilities of the local cement guys to properly shotcrete a dome. One idea was to take you up on the offer and be "on the payroll off the clock" so to speak and come work with you for a few days. I have no problems sweating as long as your teaching.
Of course that depends how hard domes are. It may be the local guys could do it, not real sure. How hard is it to put up a dome? How long does it take? And my biggest curiosity is how the heck do you make openings for windows and such? |

What the fuck were you going to do? Laugh the last three guys to death, funnyman?!

The big problem with these is getting financing on these to build them. I checked into, and because it's nonconventional structure, the lenders see it as harder to sell. But I would love to live in a mono dome. |

I was looking for pics of generator sheds and in the process I found this page:
http://www.autobestbuysweekly.com/Dome/ It sure looks like an aughful lot of work and I wouldn't want that design in an earthquake prone area for fear the sandbags would just fall in on you but it looks to be a pretty darn near bullet proof design (other then the door) It honestly reminds me of Sponge Bob's house Anyways, just sharing the link as I knew I had seen this thread and thought it was somewhat related. |

Ok, so the airform becomes the outer skin of these things? From what I can tell, the layer directly under it is insulating foam, so do they compress under heavy weight, like a big snowfall? Do they dent if a tree branch falls on them?
Are there any other downsides to these things? |

correction; after the airform, the next layer IS foam, then the rebar and concrete....I believe the foam is of a sufficiently high density to be very resistant to most normal impacts (hail, small-med branches, and so on)

Assuming the footing is poured how long does it take to do just the dome? Can a guy get one up and all finished in 2 days? Mind you I dont mean the inside, I just mean getting the foam, rebar and concrete up.

Mind you I dont mean the inside, I just mean getting the foam, rebar and concrete up. I very seroiusly doubth you could hang all the rebar and spray the foam and then shotcrete it by by yourself in 2 days seems to me the hardest part would be hanging rebar. That is if you already knew how to spray the foam and the shotcrete. I think it would probably take you two days or better to hang the rebar by yourself. |

I would say its a two man job at aleast all around.... you cant handle 40' sections of bar alone

Pics I saw the blower was on till after the shotcrete was sprayed I think. |

folks, a lot of these questions are easily answered by reading Monolithic's web page, they have articles describing all of the ones that usually arise here: underground pros and cons, how they are built start to finish, what they cost, etc etc.

It was a dome and [again,] IIRC a monolithic dome.

I would submit that it would be difficult to estimate the costs of such a design without first knowing what kind of land you will be working with. As 1BB (and MDI's website) has mentioned, going underground with domes is possible, but not very economical.
You already get most of the benefits of being underground, for much lower cost, with a regular dome. For the money you could spend in going underground, you could just add a higher grade of rebar and more concrete, and still enjoy a larger, more secure dome. I think even some comparative disadvantages of being above ground could be mitigated, like windows. Ok, spend some coin on motorized armored doors . Eye of the Storm on Sullivan's Island basically did that––they have roll-away steel shutters for the hurrican season. That place is entirely above ground, and I can assure you, it is still VERY expensive. Remember, as MDI and 1BB frequently state, cost estimates are tough, and generally, the savings aren't in the construction, but the energy costs down the road. So, let's assume $100/SF, which I think is way too conservative for what you have depicted, and you're still looking at a LOT of $$$$. I'd stay above ground. |

A dome hunting cabin. Out in the remote wilderness; perfect BOL, low maintenance, easy to heat, low Sq Ft would mean cheap to build.

So, let's assume $100/SF, which I think is way too conservative for what you have depicted, and you're still looking at a LOT of $$$$. I'd stay above ground. Whoops, I should have clarified!LOL I'd be doing the excavation myself, and it wouldn't cost me very much (barring hitting granite or something...LOL). I have easy access to a backhoe and a dozer, and with help from my family it wouldn't cost me much cash-wise beyond the diesel fuel. I'd prepare the site and have the well drilled on my own dime. I could possibly pour the foundation as well, but I'm not sure what the contractor would want as far as the ring beam, etc. entails. I was really looking at the builder coming in and building the dome on a prepped site. I was interested in building this way because I thought that using a stem wall would maybe ease up on dome costs. I thought that adding a whole nother level of space per 9' segment of stem wall might lower cost as opposed to a larger diameter dome for the same sq. footage. I'm a little sketchy on understanding if that is true though. That's kind of why I am floating this idea first. I'm interested in having an internal fallout shelter, and I know mass equals protection there. I agree that thickening the dome's concrete would add more protection, but I was thinking that if the lowest level of a dome were 18 to 20 feet (I'd back fill a little against the exterior of the 'first floor' also) below the surface I'd pick up considerable mass shielding from the soil and upper levels. The shelter level's only exposure to the surface would be from 'sky shine', and the distance and mass of the upper levels of the dome would attenuate that considerably (I would think?). Building a dome with very thick concrete walls would raise the above ground protection, but I was thinking that maybe the extra concrete could be put to use in conjunction with plain old dirt to extract extra interior below ground space for a somewhat comparable cost. I could be wrong though. I'm not up on my math enough to figure all of that out. The other thing I'd really like about a 'shelter' level is that no one (besides the builders) need know it even exists. A guest at my home would only see a conventional (well, at least as far as a dome is conventional!) home. Two story living space, with a 'basement' that is used for regular storage. I don't know if it requires extra materials or effort to build the actual dome for burial or not though. I'm wondering if a stem wall makes the dome any weaker as opposed to the 'dome' shape. I'm guessing it would be strong enough, but I figured I better ask that too. I'm with you on the armored windows! I don't think I could afford motorized steel shutters though. I was thinking hard about having steel shutter pins/hinges cast into the dome structure around the windows and doors. That way I could add my own steel shutters at my own pace to help secure the finished structure. The shutters would be steel, and I would make a faux wood "face" for the outside world to see while they were open. They would be closed and locked from the inside when "buttoning up" the dome. I get some strange ideas sometimes, so I figured I'd better hash this out in a "like minded" place. I built (with some contracted help) my own "barn" one time. It came out really well. The funny part was when the contractors (regular house builders) kept asking me questions... "Why does this place look like kind of like a fort?", "Why are the windows this high?" "Why did you backfill against the walls up to the window bottoms?" (I sunk the barn, contured the ridge sides with a dozer, and placed the structure so the windows were at chest heigth and they had perfect fields of fire on almost the whole ridge) "It looks like you are going to be shooting out of these or something?" (they were joking...) "The lumber doesn't have to be this thick".... "You are overbuilding this you know?" ( I used full dimension "rough cut") "What would you be storing up there that is so heavy...?" And on and on.... I'm happy in the knowledge that that 'barn' will be around long after I die.LOL I sold the place and the current owner plans on turning it into a huge house. If he knew what he was doing he could throw a heck of a fight from that place! Anywhoo, thanks for posting that because I needed to clarify a bit about what I was wanting to do. So you think that it would cost $100 per sq. foot to just build the shell? I'm not disputing you at all, I simply don't know. I would need the shell erected, the utilities piped in, and doors and windows (since the dome guy would understand better whatever was required with their installation). One of my brothers is an electrician and would do all of the normal wiring and HVAC later, and I have an uncle who can do the plumbing and help me with the carpentry. If I had the concrete dome portion constructed I could (with mostly family help) complete the rest at my own pace as money allows. I own my own home now (small mortgage and low bills otherwise), have a good federal job (not likely to get laid off), and would attack the interior construction with a vengeance. Another question: I'm a little cloudy with the construction of the actual floors. Besides the lowest level, would a four story structure typically have poured concrete floors? If so, does that significantly increase construction costs? I presume that steel I-beam supports of some kind would be necessary for supporting the upper levels? I would probably (depending on cost) want the dome builder to pour/construct the floors. That would help me out considerably, and I'd feel safer with someone knowing dome construction handling that anyway. Again, thanks for replying, and for any other help from anyone else too. |

I'm currently shopping for the "perfect" piece of land right now, but I'd like to be able to find a builder that could give me a reasonable estimate on what the damage would be. I'm currently thinking about something like this: http://i307.photobucket.com/albums/nn291/Variable556/Monolithicdomeprototype.jpg I think I'd like to get a 40' dome built on top of an 18' stem wall. I'd excavate down the first 18' and have the well drilled right there. Then I'd have a bison pump setup installed on the wellhead. After the dome shell was built I would then carefully backfill against the stem wall leaving a 'normal' looking 40' dome exposed above the surface. I don't know how to calculate the square footage of the top floor inside the curvature of the dome, but it would have roughly 3774 sq. ft. in the first three floors. The total square footage will be more than I actually "need", so I'm trying to get a handle on pricing to see if I can afford the shell and floors to get the structure up first. If I have a shell and floors with utilities roughed in, I can then finish up the rest as I can afford it. Any help would be appreciated. Also if any of these ideas are unfeasible/unrealistic I'd like to know that too, so I can revamp plans. Thanks in advance for any help!!! That's a pretty cool project you have there Variable556. If you want, I will work up some numbers for you to give you a VERY good idea what it costs to build that with a basic floor plan, and doing it yourself. Off the top of my head I would say around $125,000 without the shelter items. Also, your 2nd floor will have 1002 square feet with 6'3'' head clearance. More SF but you will be hitting your head. I figured it out with the 18' stem wall and a 20' dome. Basically you will be 38' tall. I will say that the shell will cost as follows doing it yourself: Airform.........$15,000 Floor...............$4,000 Foam..............$9,000 Rebar.............$7,000 Shotcrete.......$6,750 if you want it 6'' thick and $4,500 @ 4'' thick and this is mixing your own Misc...............$8,250 This is about $5,000 too high, but I like even numbers Total...........................$50,000 for the shell Should take four men about 3 weeks to build working 50-60 hours a week. That is mixing your own shotcrete. Buying off the truck will cut your time down to two weeks or so. I will answer all my emails later today. I see I have a lot of them. |

That is mixing your own shotcrete. Buying off the truck will cut your time down to two weeks or so. I will answer all my emails later today. I see I have a lot of them. Okay, I will pick up where I left off. I am going to give you an idea as far as what it will take to finish off the inside if you do it yourself. Since I am not sure what your floor plan will be, I have copied the one below and will use it as a starting point. I also picked one that was rather "BUSY" inside or crowded so we have plenty of wiggle room. I'm sure yours would not be this busy on every floor or you would have no need for several floors, so your open areas will be bigger, and material use MUCH less per floor, but again, that's fine and all that happens is you spend less money. Now that the shell is up you will want to paint it. I use an epoxy based paint. The problem is the dome HAS to sit about 45 days BEFORE the primer can be sprayed on. If you don't wait, that's fine, you can do it all over again in about 4 or 5 years when it peels off. Your choice. After the primer is sprayed then the epoxy paint can be applied. This stuff will cover about 300sf per gallon in a dome. You will have 4775 area feet over the dome shell. So, you need about 16 gallons and I can't remember the EXACT price, but it was around $50 a gallon. Don't skimp on paint. This paint is the best. I mean it cleans up like your counter top. ANYTHING that gets on your wall, wash right off including oil. You can wash your walls with a fire hose and I am not kidding. Now that I expalined that, the rest is easy, but I did want to make a point of how important it is to do the painting right the first time. Okay, now onto what it costs and how I came up with those figures using the floor plan below. " target="_blank"> The above floor plan has about 142 feet of running walls in it. You I am sure will not have that much at all, but again, if you don't, great you just save money is all, but at least you have planned for worse case. Also, if the bride wants a really really nice kitchen, you know you have the funds to do it because you have maybe 90 to 100 feet of wall. Take the above plan and multiply it by four as you have four floors, and you get the figures below. Here is the list of materials and the cost for ALL floors combined with an extra 20% added to them and rounded UP to the nearest $50. Paint and primer from above.................................$1,600 2x4 Studs.............700 @ $1.77 ea.......................$1,250 2x12x16..................170 @ $14.79 ea..................$2,550 You won't need this many, but it covers 2x8's and any other misc 2x whatever Decking 4x8............150 sheets @ $15 ea...........$2,250 Drywall 4x8............850 sheets @ $3.86 ea........$3.300 Includes ceilings for three floors Kitchen complete................................................$12,000 And no this does not include a stove, refrer, or anything like that Bathrooms.................4 ea @ $2000 ea...............$8,000 Doors, front and rear.................$750 ea.............$1,500 These are a great door and the best, but very plain Windows..................12 ea @ $525 ea................$6,300 These are triple pane windows and the best Flooring................................$3.50 psf...............$13,200 For three floors only and not the shelter Misc....................................................................$50,000 Nails, glue, caulk, lights, ceiling fans, things like that Total....................................................................$81,950 Shell....................................................................$50,000 Grand total............................................................................$151,950 I was off by $25,000 as I said above, but then again, you have A LOT of wiggle room here. You total living area including shelter is 4776 square feet giving you a cost of $31.82. If you are going to build NOW is the time as building materials haven't been this cheap for many many years. Pretend it is the stockmarket buy when it is low and sell when it is high. I have no idea about your well or how deep you are going, or a septic, so this right here will give you an idea what it costs building it yourself. It sounds like you have some good help there with the family. If you want to make the shelter NBC rated, wood decking won't cut it. You need concrete over you. That means steel trusses for support. I am not sure what they are going for as they are each built for the job, but with the wiggle room you have in this budget and MAYBE adding a few grand to it, you can get them and have at least a 4'' floor above you. Plus a concrete floor at your "BASEMENT" level will be more real to someone than a wooden floor. I want to write more about the AC and heat, as well as some ideas about the shelter. I wanted to go over what would need to be done when the dome shell is built. That is also why I added in the extra $5000 in the shell budget. I have a few calls to make right now, so I will check back later if I have time. I hope this helps and gives you an idea of what you can get and the cost. I know it is quick and generic, and over priced, but you get the idea. |

BB1. You were talking about painting the airform. What other finishes have you used on the exterior of the air form? I was reading somewhere on the MDI website about a special formula they had used for stucco. Have you tried something like that? How'd it work out?

Can you recommend anyone around south west New Mexico to do the slab and airform?

I live in WV, and googling around doesn't seem to produce squat in my area. Plus I'd prefer a recommendation from someone such as yourself. I'm currently shopping for the "perfect" piece of land right now, but I'd like to be able to find a builder that could give me a reasonable estimate on what the damage would be. I'm currently thinking about something like this: http://i307.photobucket.com/albums/nn291/Variable556/Monolithicdomeprototype.jpg I think I'd like to get a 40' dome built on top of an 18' stem wall. I'd excavate down the first 18' and have the well drilled right there. Then I'd have a bison pump setup installed on the wellhead. After the dome shell was built I would then carefully backfill against the stem wall leaving a 'normal' looking 40' dome exposed above the surface. I don't know how to calculate the square footage of the top floor inside the curvature of the dome, but it would have roughly 3774 sq. ft. in the first three floors. The total square footage will be more than I actually "need", so I'm trying to get a handle on pricing to see if I can afford the shell and floors to get the structure up first. If I have a shell and floors with utilities roughed in, I can then finish up the rest as I can afford it. Any help would be appreciated. Also if any of these ideas are unfeasible/unrealistic I'd like to know that too, so I can revamp plans. Thanks in advance for any help!!! That's a pretty cool project you have there Variable556. If you want, I will work up some numbers for you to give you a VERY good idea what it costs to build that with a basic floor plan, and doing it yourself. Off the top of my head I would say around $125,000 without the shelter items. Also, your 2nd floor will have 1002 square feet with 6'3'' head clearance. More SF but you will be hitting your head. I figured it out with the 18' stem wall and a 20' dome. Basically you will be 38' tall. I will say that the shell will cost as follows doing it yourself: Airform.........$15,000 Floor...............$4,000 Foam..............$9,000 Rebar.............$7,000 Shotcrete.......$6,750 if you want it 6'' thick and $4,500 @ 4'' thick and this is mixing your own Misc...............$8,250 This is about $5,000 too high, but I like even numbers Total...........................$50,000 for the shell Should take four men about 3 weeks to build working 50-60 hours a week. That is mixing your own shotcrete. Buying off the truck will cut your time down to two weeks or so. I will answer all my emails later today. I see I have a lot of them. Okay, I will pick up where I left off. I am going to give you an idea as far as what it will take to finish off the inside if you do it yourself. Since I am not sure what your floor plan will be, I have copied the one below and will use it as a starting point. I also picked one that was rather "BUSY" inside or crowded so we have plenty of wiggle room. I'm sure yours would not be this busy on every floor or you would have no need for several floors, so your open areas will be bigger, and material use MUCH less per floor, but again, that's fine and all that happens is you spend less money. Now that the shell is up you will want to paint it. I use an epoxy based paint. The problem is the dome HAS to sit about 45 days BEFORE the primer can be sprayed on. If you don't wait, that's fine, you can do it all over again in about 4 or 5 years when it peels off. Your choice. After the primer is sprayed then the epoxy paint can be applied. This stuff will cover about 300sf per gallon in a dome. You will have 4775 area feet over the dome shell. So, you need about 16 gallons and I can't remember the EXACT price, but it was around $50 a gallon. Don't skimp on paint. This paint is the best. I mean it cleans up like your counter top. ANYTHING that gets on your wall, wash right off including oil. You can wash your walls with a fire hose and I am not kidding. Now that I expalined that, the rest is easy, but I did want to make a point of how important it is to do the painting right the first time. Okay, now onto what it costs and how I came up with those figures using the floor plan below. http://i115.photobucket.com/albums/n295/wjf213/scan0007-3.jpg" target="_blank">http://i115.photobucket.com/albums/n295/wjf213/scan0007-3.jpg</a> The above floor plan has about 142 feet of running walls in it. You I am sure will not have that much at all, but again, if you don't, great you just save money is all, but at least you have planned for worse case. Also, if the bride wants a really really nice kitchen, you know you have the funds to do it because you have maybe 90 to 100 feet of wall. Take the above plan and multiply it by four as you have four floors, and you get the figures below. Here is the list of materials and the cost for ALL floors combined with an extra 20% added to them and rounded UP to the nearest $50. Paint and primer from above.................................$1,600 2x4 Studs.............700 @ $1.77 ea.......................$1,250 2x12x16..................170 @ $14.79 ea..................$2,550 You won't need this many, but it covers 2x8's and any other misc 2x whatever Decking 4x8............150 sheets @ $15 ea...........$2,250 Drywall 4x8............850 sheets @ $3.86 ea........$3.300 Includes ceilings for three floors Kitchen complete................................................$12,000 And no this does not include a stove, refrer, or anything like that Bathrooms.................4 ea @ $2000 ea...............$8,000 Doors, front and rear.................$750 ea.............$1,500 These are a great door and the best, but very plain Windows..................12 ea @ $525 ea................$6,300 These are triple pane windows and the best Flooring................................$3.50 psf...............$13,200 For three floors only and not the shelter Misc....................................................................$50,000 Nails, glue, caulk, lights, ceiling fans, things like that Total....................................................................$81,950 Shell....................................................................$50,000 Grand total............................................................................$151,950 I was off by $25,000 as I said above, but then again, you have A LOT of wiggle room here. You total living area including shelter is 4776 square feet giving you a cost of $31.82. If you are going to build NOW is the time as building materials haven't been this cheap for many many years. Pretend it is the stockmarket buy when it is low and sell when it is high. I have no idea about your well or how deep you are going, or a septic, so this right here will give you an idea what it costs building it yourself. It sounds like you have some good help there with the family. If you want to make the shelter NBC rated, wood decking won't cut it. You need concrete over you. That means steel trusses for support. I am not sure what they are going for as they are each built for the job, but with the wiggle room you have in this budget and MAYBE adding a few grand to it, you can get them and have at least a 4'' floor above you.

I have a few calls to make right now, so I will check back later if I have time. I hope this helps and gives you an idea of what you can get and the cost. I know it is quick and generic, and over priced, but you get the idea. HOLY COW!!! YOU ROCK, SIR!!! I'm a bit dumfounded and overwhelmed with all of the good information you have provided me. It will take me a while to sit down and intelligently digest all of that! Thank you!!!! First of all: This is awesome news, because it does definitely appear that this is feasible for me to pull off. It will take a while (still trying to find the consarned land!!!) to get a good running start on this, but I am now locked on this being what I want to do. The wife is even excited and gives the whole idea a big "green light". That in itself was a major miracle to me.LOL The sheer logic of a dome even won her over eventually. You are exactly right on my not needing such a busy floorplan also. I only want two bedrooms and two baths on the "1st" floor, and two bedrooms and one bathroom on the second floor. Good call on the kitchen also, the Mrs. wants a much bigger kitchen than we have now.LOL The bottom two levels would be finished at my leisure over a longer period. The "basement" would be half conventional storage and half "mancave", while the shelter level would be pretty spartan and be mostly open space stuffed full of preps/stores, etc., and just a few small enclosed rooms otherwise. The well is a hard number to figure around here. WV is a crap shoot for table depth. My fathers well is only about 90', one of my brother's is 160'-ish. I could possibly have a spring, or in another area I could end up drilling for China. Septic shouldn't be too bad of a problem. Until I have the property and start digging/drilling I won't know those numbers yet. My ideal location around here would be a reclaimed strip mine site. This state has plenty of them. Unless a reclaimed mine site is situated close to an urban area (for "strip" mall building LOL), they aren't all that desireable to the average joe. I on the other hand specifically want such property. HIghwalls and nice flat long narrow benches are great for shooting distance on, and are pretty defensible too.LOL The resulting ridgetops also become nice peninsulas with a view to build on providing they are accessible. Depending on the site you pick the highwalls can even give you a preview of what the surrounding strata generally is. Regarding heat: I have wondered about that one too. I would probably skip the in floor heat to save some money and opt for regular natural gas heat/central air. I'd probably want an additional source via a small wood/coal stove in the structure somewhere as a backup. I'm sketchy on that one. Natural gas is very common here, and a lot of acreages have free implied gas rights. My last property (before the one I own now) had 200Mcf per year free for one house. I like NG, and would probably only want a heat/cook stove of some sort as an emergency backup in case the gas well failed. Coal is dirty, but it is common as dirt and mighty cheap around here so I'd likely want that route for emergency use. It doesn't exactly grow old, and a fella could lay in quite a stockpile with little trouble. Besides finding the right spot of land (it took me two years to find the "perfect" place for what I wanted last time), I guess my biggest obstacle will be finding a trustworthy domebuilder with a profit margin I can afford. I'm going to print all of this out and start generating a project binder. If you ever come up this way I'll be wanting a quote from you for a dome raising if at all possible! Now that I have a good idea of what the dome will cost to build, I will only be at the mercy of the dome contractor's profit percentage on whether I can pull this off or not. If you never get up this way, hopefully some other guys will get good at it, and make it around here. I'm going to make it a priority to keep frequent tabs on this thread and watch what develops! Now I need land! Also: Any Rad math guru's out there who can help figure out what the PF (Protection Factor) would be for such a dome? The below ground distance to the shelter level and construction methods involved should give a better number than just what you'd get for a fixed overhead slab thickness for a conventional basement shelter I would think. Alpha and Beta are definitely out, Gamma is all that would be left. Gamma ray intrusion would be from overhead only ("sky shine" and decaying emitters on the shell surface), and distance would attenuate that somewhat I would think? I believe the inverse square law applies regarding emitter distance (similar to that of sound). The below surface distance plus the domes concrete in the outer shell (6"), the concrete of the "basement" floor (shelter ceiling–– appr. 4-6"?) and the additional mass involved with the conventionally constructed interior above should give a decent protection factor. I'm just not educated enough on the individual nuances of that science to peg what the actual PF would be. Regardless, I would venture it would be sufficient for this area. Still I'd like to figure it out. Well I'd better quit typing before my brain melts... Thank you for the help 1_Big_Bunker!!! If you are ever up WV way–– the beer (or whatever you drink!) is on me!!! |

In what way will this augment my ability to "render inoperative armed opponents" and break things...? (Gotta stay PC for work... don'tchya'know....)

I've always wanted to build a shelter, but it's such a hassle planning so many different things. Folding it into the bottom of a dome just seems like it would greatly simplify the issue. With my idea you'd lose the "cheap" earth mass over a regular shelter that gives an excellent "PF", but it ain't so cheap when you start burying complete seperate structures and have to allocate for them seperately. I'm just trying to figure out a way to combine the two. Granted, my eggs would be in one basket, but it'd be a darn sturdy one... Jesus said to build our house upon the rock. I'd like to think he maybe meant to build our dome there... Maybe there could be a standardized Arfcom "Survival Forum" version??? |
