Analyze feasibility of options and compare design ideas. Make technical recommendations. Methodology This study uses methods of function-centered review for the collection and interpretation of available data concerning the design and construction of pit latrine bases. Initiatives currently and previously developed were studied and assessed to orient the design process. As an assumption, all proposed designs shall reference the dimensions presented in Figure 2-5 as acceptable. A variety of materials and structures were explored to generate alternatives for the conventional latrine concrete base; 16 design prototypes were sketched and evaluated, and can be seen in Appendix A. Methodologies from reverse engineering were utilized and methods for brainstorming were explored to segregate design prototypes. For the evaluation, 5 criteria were defined: Light weight (1 or 2 people can pick it up) Affordability (by the average rural Haitian) Modularity (pieces that can be acquired separately for later assembly) Easiness to build (local skills) Easiness to move (1 or 2 people) A summary table exhibited in Appendix B uses a rating scale of when the concept satisfies “+” the criteria and when it does not. It must also be noted that the choices for material are “-” mostly context specific and based on the local environment, culture and resources. However, materials outside that description are also explored. Materials inventory Incorporating different local materials into the conventional concrete mix (like coconut shell, plastic bottles, rebar, sisal, banana fiber) presents an opportunity to create a base with reduced
