The step beyond Shelter Box

The Desperate Need
When unexpectedDisaster Strikes
This is not enough
The Problem
Many years on
The Tents will be permanent housing for many ‘til theyfall apart
“More than half of the Haitians driven into tent cities and makeshift camps have (moved out)population to 680,000 from a peak of 1.5 million, …”
Only 4.7 percent, did so because their homes had been rebuilt or repaired.
Haitians Forced Out of Tents to Homes Just as
Precarious
Sisal House ObjectiveProvide the technology
That allows locals build low cost intermediate and long term housing using:
•Simple methods and tools
•Sustainable materials
•Simple components
A Possible Solution
Housing• components made from sustainable local products• using low technology • requiring little infrastructure
A Possible SolutionHousing
•assembled from components•by local labor•using available hand tools•using Rotary innovative technology
Sisal HouseStronger, longer lasting, then tents or plywood
“Sisal House” provides locally produced structurally sound, environmentally friendly, easy to manufacture, and easy to assemble housing units . “Sisal House” structural components are made from processed plant fiber impregnated with natural epoxidized plant resin
What is Sisal House
Because ,It’s similar to …

The Similarities …
We know we can . . .
But can it be doneEconomically,
Using local fiberBioresins,
Low Technology,And Local Labor ?

The R&D Phase
Year 1 Year 2 Year 3 Year 4 Year 5 Year 5+
Phase1Prototype Development & Test
Phase 2Sisal House Factory in a Box
Phase 3Initial Adoption Program
Phase 4Diffusion Program
Phase 5Established & Technology Transfer
Tentative Schedule
The Plan
Phase 1 – Prototype Development and Test•the development and documentation of the manufacturing process•the acquisition of material and equipment to build a proof of concept model•the construction and testing of several proof of concept models •the construction of a playhouse 6’ x8’ size sample house for weather testingthe development of instructions and educational materials
Phase 2- Sisal House Factory in a BoxDevelop the sisal factory in a box equipment and material listDevelop a standardized plan and platform for sisal factory in a boxDevelop documentation of the construction process Build two or three sisal factory boxesField test the sisal factory in a box in predetermined location with indigenous personnel
Phase 3- Initial Adoption Program•Establish operating organization•Establish partnership with rotary club in a developing test nation•Develop logistics plan including customs issues•Develop test plan and schedule•Develop production schedule for 5 test units•Deliver 5 test units•Execute test plan and schedule•Based on results provide reengineering and documentation modifications as necessary
Stage 4- Diffusion ProgramDevelop diffusion plan for multiple locationsDetermine cost and price relationships for productsBuild partnership relationships with likely recipientsFormalize relationships with cosponsors Develop supply and inventory estimates for unitsDevelop and test deployment plans
Stage 5- Established and Technology Transfer Program•Based on supply estimates, build and stage sisal factory in a box units to meet anticipated demands•Continue operations
