"Dave Thacker is old school. He gives you a quote for your project and sticks to it. If he finds something he missed, he doesn't charge extra and fixes it. He gives fair quotes, works fast, and is really a pleasure to work with. While he was at my home my old fence blew down. I had him fix that too. Both the deck and the fence look professionally made, like the professionals that built them! I would definitely refer a friend or relative to PlanTrak!"

"I could not be any happier. Scott was a pleasure to work with from the start...his plans were very professional, and he was very experienced in working with the county on getting the proper permits and approvals. Scott was there every day, rain or shine, and we did have some inclement weather for part of the project. We made a few changes on the project as we went on and Scott was always very responsive to my questions and concern. He was always very polite and had a very positive attitude throughout the deck project. Anybody who needs a beautiful deck done by a true professional cannot go wrong with Scott. I am so happy with his work I have a couple more projects that I will have Scott perform for me....he is a true craftsman, and his attention to detail and the quality of his work made this a very rewarding and happy experince...I would recommend Scott to anybody!"

"Had SD Express (Honeycomb Construction) paint our garage and WOW - it made a huge difference. Overall very happy with the outcome and service provided by Eugeniu and his brother and would hire again (have already recommended him to family members). I sent Eugeniu an email and he replied promptly and came by for an in person visit to provide an estimate (I was only interested in prime / paint at first) but Eugeniu recommended that we mud / sand the walls first to give the garage a smoother finish. The estimate process was easy and when we agreed upon a date / time for service, Eugeniu was professional and arrived on time each day. Eugeniu and his brother covered the paint site with appropriate protective cover so the paint would not stain the floor or a few of our personal items that we left in the garage. They applied mud the first day, sand and prime the second day and painted the ceiling and walls the 3rd day (white ceiling and grey walls). The paint job made a huge difference - what was previously unfinished we now look forward to organizing and making it a useable space"

FAQs for shelter or outbuilding building service projects in Black Diamond, WA

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.
