Hardened Structures

Source – http://blog.wired.com/photos/uncategorized/2007/10/01/bunker.jpg

On the radio today I heard a survivor of the bushfire describe an underground shelter (bunker?). And how they were all safe below the ground as the fire raged overhead. This sent me off on a search for such spaces – and I came across this company that has an appropriate name and is in business to do provide just the space needed – to shelter from monster fire storms.

The image below – shows bunks, kitchen and work space all with battery backup no doubt.

Now I wonder if this is a line of business that is going to be lucrative in the coming months and years in Victoria and possibly all of Australia. What will the solution for the current floods in Queensland look like?


Bunkers & fortified homes for global warming, natural disasters & terrorist attacks

order to prepare for 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, resiliience and
preservation are the cornerstones and it is vital to build structures
that will enable the Client to prevent, respond to and recover from
wide a range of major events.

In an atmosphere of changing and evolving threats, resiliience and preservation are the cornerstones and it is vital to build structures that will enable the Client to prevent, respond to and recover from wide a range of major 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 facility can be protected against a wide range of threats including forced entry, climate change, chemical/biological/radiological/explosive (CBRE) agents, airblast, 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 defense and manned and mechanical responses to reduce or limit the effectiveness of any given threat along with individual/family long term living requirements.

Stated simply, a Hardened Structure is where you go when external forces are threatening your life. In most disasters the first forty eight hours are the most critical to survival and many lethal ancillary conditions develop so quickly that there is little or no time for preparedness.

  1. Very impressive but this is an extremely elaborate bunker, unnecessarily so for bushfire survival.
    A cheaper solution would be a simple circular structure made from a 3m length of large diameter (3m to 4m) concrete pipe with a 150cm reinforced concrete roof, all fully or partially buried in fill and soil. Liquid air or compressed air tanks would provide air and lightly pressurise the bunker to keep out noxious gases, hot air and embers, etc.
    Water tanks, batteries and ready to eat rations would be sufficient to last until the fire had passed.

    I cannot understand why the underground or partially buried bunker has not been adopted decades ago. People have money for pools and water tanks but their own lives seem to be lower in priority.

    The CSIRO and others should be looking at this type of solution.


  2. In fact I am now keen to start collecting visual concepts for different kinds of bunker. I spoke to Peter Ginniven who is an architect – and he mentioned that this was the topic of conversation wherever he went. Now if so many people are thinking about it – then they must also be visualizing different kinds of bunkers.

    So imagine a book, or web site which has sketches, drawings and images of different kinds of bunkers. I would like to do a project like this.

    So if you want to join in and contribute write in to me. (This is getting exciting.)


  3. Hum, I am in 2 minds about this.
    On one hand it is a technology that could provide some safety, but can everyone afford this? Should we continue living in the bush? If so should a different arrangement be tried?
    I think that microscale solutions such as this needs to respond to and be part of a wider concerted approach–one that has been fully examined. A review may suggest a completely different direction in regards to the typology and suitability of housing in the bush.
