3. Master Plan Layout • Common Building • Sanitary Facilities • Bridge • Fish Ponds • Drip Irrigation • Well • Solar Pump Design Norms - Layout - Designs - Budget - Implementation - Challenges - Questions

4. Design Norms • Cultural Appropriateness: • Through the design, materials, and construction methods of the common Cambodian. • Transparency: • Communication about the simplicity and reliability of the design. • Integrity: • Design will facilitate relationships between people and their land.

16. Bridge Design - Culverts Design Norms - Layout - Designs- Budget - Implementation - Challenges - Questions The first model made was the stream as it is now The second model was made with the dam being assumed as part of the ground and with the sides of the stream being excavated to provide room for the structure From there culverts were inserted to find out how many were needed to convey the worst case flow.

17. Bridge Design – Final Design Design Norms - Layout - Designs- Budget - Implementation - Challenges - Questions

18. Budget Design Norms - Layout - Designs -Budget- Implementation - Challenges - Questions • Projected costs were based on • Cost of materials • Cambodian price if known, otherwise price in the US • Does not include cost of labor

19. Challenges in Design • Assumptions about site data • Finding local vendors and prices for system components • Different design codes and styles between countries • Culturally appropriate design choices Design Norms - Layout - Designs - Budget - Implementation -Challenges- Questions

20. Lessons Learned Keep units straight -metric Document everything Things change- be able to adapt We don’t know everything-make assumptions Getting started is half the battle- where to start Learned a lot about different aspects of site development Communication is key between group members Design Norms - Layout - Designs - Budget - Implementation -Challenges- Questions
