  1. P14416: CONCRETE Arborloo base Evan Burley Anthony Deleo Mackenzie Keehfus Joe Omilanowicz Victoria Snell

  2. Agenda • Introduce Team • Project Background • Problem statement & project deliverables • Stakeholders • Use Scenarios • Prioritized list of needs (customer rqmts) • Engineering requirements • Draft of Project Plan

  3. Team Introduction & Roles

  4. Arborloo • A latrine-like sanitation device designed to function over a small pit and to be moved to a new pit when filled • Utilize compost by planting tree in used pit • Purpose to provide affordable sanitation in poor, underdeveloped areas • Originally designed for use in Zimbabwe

  5. Peter Morgan’s Arborloo • DIY Project • Composition • Bag of cement • “Good river sand” • Thick wire • Mounted on a “ring beam” of bricks (mold) • Addition of soil, wood ash & leaves creates compost

  6. Arborloo Shortcomings • Requires installation by mason • The slab must be kept covered and wet for up to 10 days before it can be moved and used • Expensive

  7. Haitian Arborloo/P13414 • Problem Statement: design and develop an affordable, element-resistant, portable arborloo that leverages both local and manufactured materials. In addition, the team is aiming to produce a structure that Haitians will want to own. Work led to EPA proposal to investigate more design options.

  8. P13414 Summary

  9. P14416 Problem Statement • Current State • Today’s arborloo takes two days to install and is not easily transportable. The current design is also not socially appealing to the Haitian population. • Desired State • Provide an affordable concrete base that is easy to move and install. The desired base should be aesthetically pleasing to users and a worthwhile purchase for sanitation improvements rather than storage or social status. • Project goals • Low cost (<$50 to purchase) • Base design that safely covers an 18-20” diameter, 3-4 ft. deep hole • Easily constructed using simple hand tools • Portable • Resistant to environmental damage • Has modular design • Haitians want to purchase • Constraints • Proposed budget= $1500 • Base must be relatively lightweight for transportation • Base must be made using concrete

  10. Additional Project Deliverables • Two completely different prototypes • Two molds • Design drawings (base and molds) • Assembly manuals • Bill of Materials • Test plan • Clearly documented test results • Technical paper • Poster

  11. P14416 Stakeholders Primary: • Haitian users • Local Builders • Local Hardware Stores • Local Entrepreneurs • Sarah Brownell • Brian Thorn • EPA • RIT Secondary: • Pedro Cruz Dilone (Master’s Student) • Peter Morgan • International non-profit organizations (HOPE, Pazapa) • Jim Myers- Associate Executive Director of HOPE • SOL (SosyeteOganizePouLanati) Society organized for nature- local organization • Ministry of Public Health and Population • Mayors (Local Government)

  12. Use Scenarios Considered Scenario 1: Arborloo bought by a really poor family and has to carry it for 6 hours from the store to their home. Scenario 2: Arborloo bought with all the different options, by a “middle class” family trying to show off their social status. Scenario 3: A contractor is installing multiple Arborloo’s a day and can make more money the faster he installs them. Scenario 4: A heavy set individual, weighing approximately 250lbs buys an Arborloo and uses it on a daily basis

  13. Customer Requirements Importance Scale

  14. P14416 Engineering Requirement

  15. House of Quality

  16. P14416 Preliminary Schedule Develop project plan Define team roles Code of ethics, team norms and values Create website homepage Create peer review form Peer reviews Prepare project review Finalize House of Quality

  17. Next Steps • Benchmarking • Various concrete research • Concrete mixture testing

  18. Issues & Corrective Actions • Unlikely will be able to interact with users directly • Will need to get feedback from a variety of sources (individuals who have traveled to Haiti, past projects, other cultural resources) • Lack of expertise on concrete and its strength • In contact with Civil Engineers at RIT • Contact with concrete specialist in ME-T program at RIT • Currently waiting for Haitian concrete materials • Research on different types of reinforcement for concrete Questions/Feedback
