"The bonus room, above the garage, was the coldest place in the house in winter, and the hottest in summer.   Air was coming in through the trim/baseboard, and the sub-floor itself was very cold in winter.  The goal Omni Services (OS) and I agreed to was to provide a year-round comfortable space.  As a consumer, I wanted the room to be "air tight" but OS could not guarantee that.
In preparation for the bonus room work, I removed the trim, carpet and pad for later re-use, and cut out (as best I could) some agreed-on 4x8 and 4x12 sections of the existing drywall, so we could see what was going on inside the walls and ceiling.  The scope-of-work document had Omni Services (OS) removing the sub-floor as well, to check out the insulation beneath it, but ultimately OS didn't deem that necessary, as they found a different way to add insulation. [So in hindsight I removed the carpet and pad unnecessarily.]
OS determined:
  a. the ceiling insulation was wrong for the space (R30 was crammed in, R19 should have been used)
  b. the roof above the bonus room (2x8 boards between the ceiling and the roof) had insufficient  ventilation
  c. there was insufficient insulation in the garage attic (adjacent to the bonus room) that was a continuation of the roof above the bonus room
 
What OS did for the ceiling:
  a. removed the R30 from most of the ceiling
  b. installed "proper vent"  (a way for air to flow between the lower and upper parts of the roof) where the R30 had been
  c. replaced the R30 (that was removed) with R19
  d. added some exterior ventilation (around the gutters and in the garage attic) to allow more air into the "proper vent"
  NOTE:  I had a roofing company install ridge-cap ventilation above the bonus room; OS's work was pointless without that
 
What OS did for the garage attic adjacent to the bonus room:
  a. install foam board insulation over the sloping area (continuation of the bonus room roof, into the attic)
  b. spray in more insulation
What OS did for the sub-floor:
  a. accessed the underside of the sub-floor from either the garage attic or the limited space between the bonus room walls and the ceiling (which continued downward into the garage attic)
  b. sprayed in more insulation
THE BAD: Once the drywall was replaced, taped, etc., and before the trim was put back on, there was still significant airflow into the room, where the drywall met the sub-floor.  I had not expected this, nor had OS.  I "fixed" this by using a combination of low-expanding foam from a can, leftover fiberglass insulation, and drywall mud.  Air was also coming in from the drywall holes cut for the electrical boxes, but styrofoam covers fixed that.
What OS did for the main attic stairs (accessible from the bonus room):
  a. manufactured a cover using leftover foam board and other materials
  b. installed the cover above the pull-down attic stairs
  c.  sprayed in more insulation in the attic, in the area around the new cover
What OS did for the doors:
After I removed the trim from the French doors, OS replaced one of the doors, which had warped.  I painted the door, then OS reinstalled the trim.
BOTTOM LINE:  We do not yet know whether the bonus-room goal was met.   We won't know until we have a string of really hot days, and another string of really cold days.

FAQs for shelter or outbuilding building service projects in Eaton, CO

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.
