An underground bunker is a form of shelter that provides protection from enemy attacks. It is built in the ground, and its walls are made of reinforced concrete. The bunker has several rooms, including a dining room, kitchen, bathrooms, bedrooms, and an office.
The underground bunker was invented during World War II. It is used by soldiers who live there during wartime. In addition to providing protection from enemy attacks, such as bombs or bullets, an underground bunker may also serve as a storage area for supplies such as food and water.
The Deep Underground National Military Command Center, or DUMB, is a secret underground bunker designed to withstand a nuclear attack. It’s been around since the Cold War and is believed to be located somewhere in Virginia today. So what would it cost to build your own? Let’s dig into the numbers.
The size of the bunker
The size of the bunker will depend on the number of people who will be living there and their daily needs. A small bunker can be built for a few thousand dollars, while a large one can cost as much as $1 million.
According to [Bunker Builders], an underground bunker costs around $5 per square foot, excluding labor and materials such as steel reinforcement beams and concrete flooring. The price also varies depending on the type of foundation used: a concrete slab or poured-in-place footing may cost more than rebar because they require additional work in preparation before construction can begin.
You should also think about how much space you’ll need inside your bunker, which will determine its total square footage. If you want enough room for yourself plus three family members, then your final cost could hover around $25 per square foot, but if you’re planning to fill up an entire underground city with thousands of people (yes please), then that figure could easily reach into six figures.
Who are you building it for?
If you are building the bunker for yourself, then the cost is going to be much lower than if you were building it for a group of people. This is because with groups, there are more people involved and therefore more materials are needed. The other factor that affects how much it will cost to build an underground bunker involves how many people are involved in building it. If you were going alone, then it would probably take less time as well as money since there wouldn’t be anyone else in your way or slowing down progress on your project.
What will they be doing in the bunker?
First, it depends on how long you want to stay down there. I recommend staying for at least 6 months (probably more). This should give you enough time to figure out what kind of life you want to build down below and whether or not it’s worth staying longer. If anything happens during those first six months and your family needs to go back up above ground again, then do that. But if everything is going well and everyone is happy living in the bunker then by all means stay down there as long as possible.
How will you get the power down there?
There are four main ways you can get power to your bunker: solar panels, wind turbines, a generator, and hydroelectric dams.
Solar panels are the most efficient way of generating electricity. They harness energy from the sun by converting it into electricity using photovoltaic cells that turn light into direct current (DC). The DC travels through an inverter to change it into alternating current (AC), which is used by appliances like lights and computers. Solar panels need direct sunlight so they won’t work well underground but if you’re looking for a long-term solution, this is a cheap option that doesn’t require maintenance or fuel costs.
Wind turbines generate electricity by converting kinetic energy from the wind into mechanical energy which then turns an electrical generator inside the tower of the turbine, to create an electric current. Wind turbines can also be used as backup generators during emergencies or when there’s no sunlight available for solar panels; however, these turbines are expensive compared with other forms of renewable energy sources like hydropower dams or oil wells which require only minimal maintenance work over time periods ranging anywhere between one day up until several years depending on how often they need repairs due primarily because they don’t require any kind whatsoever on account being able to run themselves without any outside intervention being needed whatsoever which makes them ideal choices, especially if considering building one yourself because they’re relatively easy when compared alongside other forms such as solar panels where the installation will take longer than normal.
Do you need communication capabilities?
If you’re building a bunker, it’s likely that you want to be able to communicate with the outside world. This can be done through cell phone service, internet connection, and radio or satellite communication.
Cell phones will work as long as there is power from above ground (so long as the cell towers are still up). You can buy an old-model flip phone or get a new one for about $30. These won’t have internet access but they do have text messaging capabilities. There are also no monthly fees associated with these old-model phones. If you want to bring along some of your favorite apps like Facebook Messenger or WhatsApp then consider getting an inexpensive smartphone instead of a flip phone, you’ll still need to pay for service though so factor this into your budget considerations as well.
Foundation
The foundation is the most important part of a bunker. It must be at least 8 feet deep and sit on a concrete slab. The reinforced concrete should support the weight of the structure above it, which can be upwards of 20 feet in total.
Materials needed to Build An Underground Bunker
Steel is a building material that has been used for centuries. It’s strong, but also flexible enough to bend and flex without breaking. Steel is a versatile material that can be used in the construction of buildings, structures, bridges, and even airplanes. Steel is also very durable, meaning it will last long after other materials have deteriorated or broken down completely.
The most common type of steel used in the United States today is hot-rolled steel (HRS). Hot rolled steel is produced by rolling molten metal into flat sheets which are then cooled down by passing them through water baths at high speeds. The cooled sheets are then cut into smaller pieces called blooms; these blooms are further processed into slabs which are then rolled flat again before being shipped out to manufacturers who use them to build products like cabinets or appliances.
Piece of land needed to Build An Underground Bunker
The amount of land needed to build an underground bunker is dependent on the size of your bunker. If you plan on building a small, simple bunker, you will need less space than if your intention is to build something larger and more complex. The cost per square foot also varies depending on how much land you buy and what kind of soil is underneath it.
The cost of building this type of facility also depends heavily on who does the work for you and their experience level in this area. For example, if you have access to experienced builders who have built other similar facilities before then they will be able to save time during construction which would reduce costs but vice versa applies too since inexperienced workers might take longer than necessary which would increase expenses overall.
Labor cost to Build An Underground Bunker
Labor costs are a big consideration for any construction project. When it comes to underground bunkers, labor is going to be one of the most expensive parts of the project.
The first thing you will want to do is hire an architect who specializes in underground bunker design and construction. This person will help you design the perfect bunker for your needs, as well as give advice on how much it will cost and how long it will take for your workers to complete the job once they start building.
You should also hire several contractors who specialize in digging trenches into solid rock or dirt so that they can begin digging out an area where they can build an underground shelter with ease. It’s important that these workers have experience working with heavy machinery such as backhoes because this kind of equipment is often required when building bunkers outdoors or even indoors if there isn’t enough space available around them without causing harm (such as accidentally knocking down walls).
Maintenance cost to Build An Underground Bunker
The cost of maintenance for an underground bunker depends on the type of bunker that you build. If you have a fireproof, waterproof and airtight shelter that is made with thick layers of concrete as well as steel reinforcements, then it will be more expensive to maintain than a simple metal shed or basement. The size and location of your underground bunker also play an important role in maintaining it. For example, if your home is located near the sea, then there will be frequent flooding during heavy rainfalls which could damage your shelter’s foundation walls. This can lead to cracks or leaks developing over time which may require repairs every few years or so depending on how often they occur.
Your underground bunker will probably cost about as much as a whole new house.
Your underground bunker will probably cost about as much as a whole new house. It’s hard to give an exact number because every bunker is different and the price varies depending on its size, location, and amenities. But here are some general estimates:
- Construction costs can be anywhere from $25 per square foot up to $100 or more depending on how big your underground bunker is going to be and what kind of materials you use (timber vs cement block walls). If you’re building something with concrete walls, this could easily add up to over $1 million dollars just for construction alone.
- Your other costs include things like land acquisition ($500+/acre) and design fees (5%+) which would bring your total up even further. Adding in other expenses such as landscaping/concrete work around the exterior perimeter (if applicable) might add another 10-15%. In addition, there may be other hidden costs that come up during construction such as permits or licenses needed during certain stages of a building if anything needs special attention like environmental impact studies which could cost several thousand dollars depending on the scope of work required at those points along with additional fees charged by contractors who handle these tasks professionally rather than doing them yourself, all adding, even more, $$ onto your initial budget before even beginning construction itself.
Cost to Build An Underground Bunker
The cost of building an underground bunker depends on the size of the bunker, who you are building it for, what they will be doing in the bunker, how you will get the power down there, and if you need communication capabilities.
It’s important to note that when describing costs here that we are talking about a single person or family who is looking to build a small underground shelter on their own property. If you’re interested in getting something larger built for multiple families or groups of people then things become much more complicated and expensive very quickly.
All in all, it costs a lot of money to build an underground bunker. The materials are expensive and difficult to acquire, but the biggest expenses lie in the labor required to construct such a structure. A large part of the cost is due to the fact that many people would need assistance with digging out dirt and rocks by hand – not only because they’re just physically unable to do so alone, but also because machines like backhoes aren’t well-suited for this kind of work.
