"Precise Design Construction LLC was by far the best We have had dealings with over the past few years. We were displaced because of the 2016 flood. After contacting multiple contractors and getting outrageous rates. We no longer want to keep our home. Forward, years later we ran across Precise Design Construction LLC. It is been a dream come true."

"Everything went well. Beautiful work and always fair with the pricing. Will always knows the right materials to use when building, never cheap materials. Never in a rush neither but always finishing in a timely manner. If Will says it will take a week, a week is what you’re looking at. Always true to his word."

"It did not go as well as we had hoped.  He missed straightening out/tightening  some of the siding slats and I had to call him back to make corrections in the places which were still sagging.  He did not appear to understand the type of repair that was needed to straighten out and secure the siding slats.

"Benny and Acadian did a great job on two separate projects for us. First (early 2016), we had an old attached carport in our backyard that was no longer used as a carport. We wanted to convert it into a storage shed. He gave us a fair bid (we took 2 other bids, 1 was much higher than his and 1 was comparable). His workers were very considerate and professional when we met them. Benny was very responsive when I had questions. The project was fairly involved, because they needed to move some HVAC units out of the way, expand the size of the concrete foundation, frame the walls for the shed, wire the shed for electricity, replace the carport lighting fixture, install exterior lighting fixtures, and install and paint exterior siding to match the house. They did everything perfectly! Second (mid-2017), we hired them again a year later to replace the old railing on our front porch. We had a miscommunication with Bennie about what we wanted the replacement to look like. But Benny and his carpenter were very responsive when we realized that what his carpenter was constructing for was not what we wanted. They quickly changed course to build what we wanted and we really appreciated the quality work and professionalism. We are in the process of getting a bid from Acadian to do some more work for us!"

FAQs for shelter or outbuilding building service projects in Harvey, LA

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.
