== A Note On This Plan ==
I presented this outline to two of the Directors of the American Red Cross in Washington, DC earlier this year. Their response was extremely favorable, calling the plan "incredibly innovative; as good as anything we have seen."
 
The technology parts of this plan: a GIS, perhaps some online training tools, and a database application are well below the level of complexity of many services offered by, for instance, Yahoo or Google. An organization like that could build and host this service (except the financial infrastructure) as a way of helping ordinary Americans protect themselves in the event of a natural disaster or terrorism.
 
To do the supply chains for the building materials would require assistance from building supply companies like Home Depot or Lowes, and the tape is going to need to be stockpiled - call 3M. But with these pieces assembled, plus perhaps some of the additional infrastructure components outlined in the [[Media:Hexayurt_pentagon_presentation.pdf|presentation PDF]], there is no reason why an extremely high level of resilience could not be achieved without requiring complex government planning.
 
 
You can build a hexayurt yourself.
 
You can build a disaster response capability based on the hexayurt by working with your community and some companies.

= A novel approach to handling mass refugee situations in the United States =

== Introduction ==
This document outlines a low cost ICT/training approach to handling
millions or tens of millions of domestic refugees in the event of a natural
disaster, epidemic, industrial accident, WMD or other event. The basic
building block of this response is a low cost building called the Hexayurt  
which can be rapidly manufactured and assembled using common
materials by semi-skilled teams. We then proceed to show how these
simple, high quality shelters can be distributed and sited in a way which
enables the non-displaced population to seamlessly absorb the displaced
people at minimal cost.
 
==Hexayurt Properties ==
A hexayurt is a 166 square foot "microbuilding" assembled from one to
two dozen 4' x 8' panels. These panels are typically off-the-shelf
polyisocyanurate building insulation boards, as commonly found at Home
Depot and other building supply outlets for around $15 ea. Harsher
climates and longer term use requirements can be met by custom runs of
this material. The building geometry is extremely simple: the roof is
made from half-panels, and the walls are made from full panels - an
entire building requires only six straight cross-panel diagonal cuts. There
are no framing timbers or other structural components. The pieces are
then joined using an off-the-shelf 6" wide 600lb breaking strain
industrial box closure tape or a custom adhesive. The entire process -
from panels in a truck to a finished building - takes about two hours the
first time and more like one hour with an experienced team of five or six.
The design is in the public domain so can be used by anybody.
 
== Shelter for One Million Families ==
One hexayurt can house a family group of up to five people. Building and
siting one million units in three days is achievable at a cost ballpark cost
of under $700,000,000 ($120 per head) given preparation, training and
supply chain management. The notion is to use these buildings as “guest
quarters” for refugees, to be added to existing family homes that provide
hospitality and infrastructure.
 
== Manufacturing the Hexayurts ==
The materials cost for each hexayurt is around $200 for very basic
temporary units, through to about $600 for long-term high durability
units. Cutting a factory-quality hexayurt takes about two hours with a
single table saw, or about 30 minutes with garage space, two saws,
timber jigs and a small team to cut, move stock and finished panels. Pre-
assembling the walls and roof into a folding unit takes about another 30
minutes for a second team of three to five people. A unit built this way
can be assembled on site in about an hour by a team of three. Each shop
requires well under $1000 of equipment and can produce around 50
units (housing for up to 250 people) per day assuming three shifts. Note
that the manufacturing capacity costs are around the same as two units.
 
Given these figures, manufacturing one million units in two days requires
10000 shops. Equipped from scratch, this is $10,000,000 of capital
investment. However most of the required equipment is already in
widespread use - table saws and 2x4 - so most of these shops would not
have to be set up from scratch. Indeed, in a real disaster situation, the
goal would be to press all available capacity into service.
 
The materials themselves, at over-the-counter prices, would cost
$600,000,000. Polyisocyanurate boards are in common use all over the
country in the building industry, but the total volume available in the
supply chain, and latency for further manufacture on an emergency basis
has not yet been researched. It is likely that the various manufacturers of
these products could stockpile the liquid chemicals required and step up
production in a crisis. Another issue is tape - 6" wide bidirectional
filament tape is widely available but not widely used. It may make sense
to simply stockpile the required tape all over the country.
 
=Staffing the Manufacturing Operation =
The Red Cross training courses all over the country. Adding an
"emergency shelter" training course, where volunteers are trained and
certified to manufacture, site and assemble hexayurts and similar
building systems, seems like a reasonable way to build local capacity.
People with the certification could additionally register as having a shop
with a “crew” – a staff like a volunteer fire department – who could
manufacture units at a given capacity if materials were available.
 
To have 10,000 shops ready in the area around a disaster seems
unrealistic at first. However, with the exception of the Mid West, cities
cluster. A multi-year program to build local capacity could easily find
5,000 shops in most major cities. In a crisis, capacity close to the disaster
is activated first. The trained staff of each shop would be augmented by
other, unskilled volunteers who would pick up basic skills on the job.
 
= Siting the Buildings =
Buildings should be put up in the back yards of ordinary American
families. The infrastructure requirements of one million families cannot
be effectively met by large, centralized facilities. However, existing
oversupply is so large that, for many Americans, providing a place to
cook, shower and watch TV for a guest family in an emergency would not
only be no hardship, but a welcome opportunity to participate.
However, it is unrealistic to expect this kind of meeting of overcapacity
and need to happen ‘on the fly’ when considering mass evacuation.
 
Therefore a national register of families willing to site American refugees
in their back yards would be created: a centralized GIS database showing
locations where hexayurts could be sited would be created and, in the
crisis, individual evacuation maps would be prepared.
 
The first step is that the GIS marks off the areas which are effected in the
disaster, and a first estimate of the refugee population is made. Secondly,
information about local transport conditions is added: if major highways
are out, they would be taken off the map. Finally, the system begins to
identify the “closest” sites for hexayurt placement based on a transport-
driven distance metric, rather than simply distance. These homes are
contacted by an autodialer or SMS message and an automated system
asks if they will be there to help receive an incoming family.
 
This “readiness roster” is then passed to a second system which
communicates with the manufacturing shops; shops in each area are
married to a set of sites and, as units come off the local production lines
they are transported by pickup truck (one truck can take 5 units) to the
home sites, where neighbors assemble them and wait for the refugees to
arrive. I would foresee an additional “transport corps” which would help
take refugees from centralized pickup points to their interim homes.
The requirement for databases with cell phone access to manage this
entire process cannot be overstated. Although clearly a backup system
based on paper is possible – maps printed off at a centralized location
and then flown into the disaster zone and handed out to refugees – the
challenges in keeping basic communications available and building
robust interfaces to the planning databases are likely a lesser challenge.
 
== Managing the Supply Chains ==
In order to smooth this process, every American should be issued with a
debit card akin to the FEMA cards or prepaid debit cards as commonly
used. These cards should ship in the “deactivated” condition. When a
crisis happens, the cards should be enabled either nationally (in the event
of a huge crisis) or locally – for example, turning on all the cards for a
given set of zip codes. All the cards for people on the rosters as either
manufacturing hexayurts, hosting refugee families, or otherwise
providing services should also be enabled, with balances reflecting the
expected expenses incurred by each group. For example, a
manufacturing shop could easily go through $30,000 of building
materials in two days and should have credit available to this task. This
“pay as you go” approach to managing the supply chains has multiple
benefits including empowering individual Americans to help themselves,
and working smoothly with existing supply chain systems in place in
building supply stores.
 
Because these cards are issued in peace time to individuals, and have
strong identity information attached to each one, it should be possible to
track fraud and abuse. It should also be possible to call an automated
service and requisition additional card capacity so that, for example, an
individual traveling in the disaster area can call in, activate their own
card, and get out of trouble.
 
== The Hard Case ==
This entire approach involves using overcapacity in the national system to
cover Americans affected by disaster. However, in a bigger disaster, the
national communications and electrical infrastructure may simply be
unavailable. What then?
 
In these scenarios, local stockpiles of tools, material and information
provide the only hope of effective local grass roots response. For
example, schools could be nationally understood as being gathering
points for planning groups, and school busses could drive their normal
routes at all hours of the day and night to provide transport to these aid
hubs. The [[Media:Hexayurt_pentagon_presentation.pdf|Hexayurt infrastructure package (pdf)]] for the developing world
includes heating, electrical lighting and various other essential services
and an upgraded version of this package could be manufactured and
stockpiled for use in crisis conditions in the United States.
