"I highly recommend JDS Improvements - for roofing or any other work. (I will be hiring him to do other work around my house later this year.) He removed the old roof and two skylights and replaced them. He coordinated with the HVAC company to remove and replace the roof air conditioner so I was without air conditioning for only a few hours, which, in Arizona is so needed in July! He repaired the inside walls/ceiling that had to be trimmed to accommodate the new skylights. Extremely professional, IMPECCABLE INTEGRITY, responsive, listened and answered all of my many many questions, and accommodated my special needs. His crews are very respectful and after the work was done they cleaned up all areas - inside and outside. When they had to work inside, they put paper on the floors to walk on, paper on the counters, and then put plastic around the skylight opening when they repaired that area. They cared for and respected my house as if it was theirs and left it clean with no trace they were even there. Nothing was too small - the attention to the details was welcoming. Having lived in Sedona for 10 years I have finally found a contractor who does what he says he is going to do, shows up when he says he is going to show up, and not only walks you through the process but also talks to you about possible complications/issues and offers multiple solutions. QUALITY WORK AT GOOD RATES. I know I will never hire any other contractor for any home project I have in the future!! I know that I will never have to worry that the job was done right - the first time!!!"

"Dakotah Construction was able to install a concrete in my property. The work was competent and the price was reasonable. In addition, they were able to work with minimal supervision and were able to deal with some fairly sticky officials (who were just doing their job, I guess). We negotiate contracts on a Request for Proposal basis. When we do our next project that requires concrete or excavation work, Dakotah Construction will definitely be at the top of the list of invitees."

FAQs for shelter or outbuilding building service projects in Flagstaff, AZ

A bomb shelter is an abode built to withstand disaster. Bomb shelters may refer to a space or bunker that can protect inhabitants through a hypothetical nuclear attack, apocalypse, or any other massive crisis. People usually build bomb shelters underground and stock them to live there a few days to a month at a time. Doomsday bunkers accommodate long-term living rather than just through a short crisis.

Builders construct bomb shelters with reinforced steel, box culvert, concrete, or other durable materials (but many professionals do not recommend shipping containers, as they’re not designed to live underground. If building underground, you’ll first have to excavate land before building the actual structure. You’ll have to implement air and water filtration systems, septic systems, and power supply.

It takes a lot of experience to safely and legally construct a bomb shelter, not to mention make sure it’s fit to live in for extended periods of time. It’s best to talk to a residential structural engineer near you for proper guidance.

The current standard filtration systems require filtering both air and water. For air, you’ll want an NBC filter system, which both domestic and international producers make. NBC stands for Nuclear, Biological, and Chemical, which filters out all three. If you’re only building your shelter for natural disasters, chemical attacks, and biological attacks, you may opt for the less expensive HEPA filter system. 

Water filtration requires the same level of care. You’ll likely want to have a large water storage capacity to survive short-term disasters. For long-term living, you’ll want to have a water filtration system.

Rising S bunker prices depend on the size, ranging anywhere from $20,000 to $9 million. Their least expensive model is 96 square feet while their most expensive model has a gym, swimming pool, hot tub, and bowling alley.

  • Mini: $45,500

  • Standard Bomb Shelter: $67,500–$109,500

  • Silver Leaf: $140,000–$182,500

  • Admiral: $180,000–$500,000

  • Xtreme: $450,000–$780,000

  • Xtreme Bunker Complex: $840,000–$1,830,000

  • Luxury Series: $3,800,000–$9,600,000

You almost always need a permit to build a bunker on land with any type of public utilities running through it. You’ll want to check with your local building code enforcement agency to see if this is the case for your area. 

Because you’re building a structural component that often requires electricity, water, and sewage services, you’ll need to apply for permits to attach these utilities to your new property. However, off-grid-only units in rural areas may not need all or any of the permitting you’d normally find in more urban settings.

To survive a nuclear blast, you’ll need to have your bunker at least three feet underground. However, it’s usually advisable to put it further underground. To survive a close strike, you’ll want to have the bunker at least 10 feet down and with five-foot thick reinforced concrete. However, knowing exactly how deep to build depends on the size of the blast you’re trying to avoid. Most bunkers don’t need to be more than 5 feet below the ground.
