At Hardened Structures our Fortified Homes can range from a single safe room to a multi-building self-sustaining, defensible, survival community. We offer blast, ballistic and fire resistant exteriors along with numerous defensive and offensive options.
In order to prepare for anarchy, eonomic collapse, armed assaults, terrorist attacks, global warming, major disasters and other emergencies, it is impossible to maintain the highest level of preparedness for all possibilities all of the time. Given limited resources, managing the risk posed by major events is imperative. In an atmosphere of changing and evolving threats, resilience and preservation are the cornerstones and it is vital to build structures that will enable the Client to prevent, defend against and respond to and recover from a wide range of Major Threat Events. 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 home can be protected against a wide range of threats including forced entry/assaults, climate change, chemical / biological / radiological / explosive (CBRE) agents, air-blast, ground shock, penetration, fragmentation and damage to the structure and equipment due to explosive loading.
Along with the Client's particular living, function and storage requirements, the designs also incorporate active offensive and defensive components, and mechanical responses to reduce the effectiveness of any given threat while providing for individual/family long term living requirements.
Fortified structures are special, and so are the people who choose them. At Hardened Structures confidentiality is paramount. We serve as our Client's agent, representing their best efforts by professionally and stealthily implementing a design/build program to meet any Threat Event.
