A Hardened Structure Facility can be constructed in most localities, urban, suburban or rural. By its nature, a Hardened Structure is usually designed to perform its primary mission both during and after a war-like or criminal attack, in the event of a major natural disaster or accidental / man made emergency. Thus, making hardening one of its primary requirements and a significant part of the cost.
We address these challenges by employing a Multi-Hazard Engineering methodology that not only recognizes individual hazards / threats sequentially but also address all hazards/threats simultaneously as a problem of optimization under constraints. The facility can be protected against a wide range of threats including forced entry, armed assault; chemical, biological, radiological, explosive (CBRE) agents, air-blast, ground shock, penetration, fragmentation and damage to the structure and equipment due to explosive loading.
Hardened Structures Hardened Shelters, LLC is the US distributor for #TEMET brand products. TEMET is the world leader in Hardened Shelter Technology providing protective solutions for all types of civilian and military protective structures.
TEMET has been active in this technology since the 1950's, conducting research, development, testing and production of all critical components and systems of hardened shelters. The Finnish legislative requirements and long-term shelter building program for the civilian population has laid the foundation for TEMET's strong technological standing in shelter technology.
TEMET's strength is the ability to rapidly develop new protective solution applications to meet with the most demanding protection criteria. Teaming together, Hardened Structures and TEMET will provide peer plan reviews of the shelter layout, functionality, system equipment, egress and ingress of the shelter.

Projects : Examples 2015
A. A bunker, 10’x50’ (500SF ) , prefab steel unit, plus underground generator enclosure, tunnel to master bedroom, escape tunnel . . .
The excavation was for an actual permitted swimming pool, pool deck and cabana. The bunker went under the cabana and pool deck, and a midnight overnight delivery and backfill.
B. A 250SF earth sheltered one bedroom suite with full EMP protection and off grid energy. EMP shielding drove the price higher.
C. A 600SF two bedroom plus loft hardened retreat home. Earth bermed.
D. A new 3,500 SF hardened home with an additional 800SF hardened bunker.
E. Safe rooms - how long one is going to stay in the safe room makes a huge impact. 12 hours is far different than 72 hours. And beyond 72 hours becomes a full specification bunker project.
F. Survival retreats both within the USA and internationally - ongoing.
