While there are different people have different threat levelpredictions, all Hardened Structures Shelters generally function as a stand-alone fortress. Self Rescue supplies and Emergency Escape man-ways are included in the basic design as to allow radical movement of the structure and extreme surface conditions. If this shelter is forced to the surface it will be capable of surviving all of the above threats absent the protection of earth coverage. PostAttack Recovery Plans and resources are incorporated to be utilized during the anticipated after-effects of the 2012 Threat Event Scenario.

PROTECTION PROGRAMMING FOR A 2012 EVENT

Threat Assessment:
A Hardened Structures 2012 Shelter is typically designed and constructed to mitigate the following Threats. 1. 2. 3. 4. 3-Bar Blast Overpressure of 45 psi Force 10 Earthquake in successions 450 MPH winds Extreme Gamma & Neutronattenuation from a 100 megaton air burst detonated 20 miles away 5. 6. 7. 8. 9. Solar Flares with 1,000,000 volt (EMP) Flooding (submersion for 500 hours) Extreme External Fires at 1250 F for 10 days Magnetic Pole Shift Chemical, Biological, Radiological, Nuclear (CBRN) Weapons

10. Forced Entry and Armed Assaults 11. 12’ of snow and 10’ of rain 12. 97 lb Hail Stones at a speed of 100 mph

GeneralSpace Requirements:
The shelter is anticipated to incorporate the following spaces: Bedrooms, Bathrooms, Air Locks, 1Decotamination Room, 1-Kitchen, 1-Den, 1-Communal Space, 3- Store Rooms, HVAC Equipment Room, Battery Room, 2-Emergency Escape Tunnels, Power Control Room with Generator, Firearms/Ammunition Vault and required fresh air intakes and exhausts.

StructuralRequirements:
The shelter shall be designed to withstand 3-Bars, or 45 psi of applied overpressure. All penetrations thru the shelter envelope must utilize blast valves and blast doors. Concrete admixtures for moisture control and water penetration will be required as well as additional reinforcing detailing at all penetrations. A Mat-type 4000 psi cast-in-place concrete foundation is envisioned withconcrete walls between 1’-4” to 2’-2” thick. A cast in place concrete ceiling approximately 2’-4” to 3’-6” thick is anticipated. A Blast suspension system typically will not be incorporated.

Mechanical Requirements:
1. The shelter shall be designed to operate “off the grid” without outside utility support. The shelter will be connected to the existing electrical service and shall operate using...
