==Abstract==
<center>''This project is a collaboration between students enrolled in the Practivistas Dominicana Program and the rural community of Las Malvinas in Santo Domingo, Dominican Republic. The community center in Las Malvinas currently functions as a space for the community to hold meetings and workshops; however, the lack of a durable shade and rain-proof structure along the outside of the building has prevented the community from being able to use the space when weather conditions are too hot or too rainy.''</center>
==Background==
The client at hand This project is in the community of Las Malvinas in Santo Domingo, Dominican Republic. They have requested that a rain/shade structure be built by Practivistas Dominicana at their local community center (Estacion Ecological Comunitario) between May-July 2014. Three of the students working on the project are from Humboldt State University in California and one student from Universidad Iberoamericana in Santo Domingo, Dominican Republic. After a community meeting was held, it was determined that the structure should be able to protect from rain as well as sun so the community could hold meetings, classes and workshops in comfort. Community members voiced their opinions that aesthetics, durability, and locality of materials were some of their main concerns in regards to the construction of the structure. Bamboo and palm fronds are some of the possible local materials that could be utilized [[Image:Las_Malvinas_current_shade.jpg|thumb|center|500px|Previous Las Malvinas Community Center Shade Structure]]
==Problem Statement==
===Criteria===
This section includes all possible aspects thought up by the group members for this project as well as the community members of Las Malvinas and the directors of Practivistas Dominicana. These criteria were chosen to evaluate the project based on protection, locality, and durability. These criteria will help us to determine how much time, money, and effort should be invested in each aspect of the system based on its importance to our client (the community of Las Malvinias)Malvinas.

==Literature Review==
See [http://www.appropedia.org/[Las_Malvinas_community_center_shade/Literature_Review Las Malvinas community center shade/|Literature Review]] for information relevant to this project.
==Final Design==
 
Our final shade structure was made out of a mix of different materials. The vertical structural posts and the truss system were made out of bamboo. The left side of the structure seen below was reinforced with wood 2x4s and the roofing was made out of corrugated zinc. The materials were fixed together using wire and nylon rope. On the right side, the bamboo trusses were reinforced with a wood 2x4 going across the top. The billboard canvas was wrapped around a 2x4 on each end and fixed to the roof using nails and staples. The ends of the 2x4 that went across the edge of the bamboo were lashed using wire. The billboard canvases were fixed to each other using vinyl glue.

==BudgetCost==This is the proposed draft budget final cost for the completed shade structurein Las Malvinas. Initially, a budget of approximately US$400 was set, but as the project developed, and the true desires of the client were determined, a larger area was to be covered and the structure also needed to protect against rainfall, therefore the final cost was slightly higher than initially thought.

==How toWe==
See a step-by-step process of how this structure was built and how to recreate a similar structure below:
|3| After taking proper measurements for the location of the community center, we cut bamboo to the appropriate lengths. We then made a concrete mixture to secure the poles into the ground surrounding the perimeter of the existing structure. Finally we inserted rebar into the center of the bottom culm and ensure that the concrete is inside the entire bottom culm.

|4|When concrete is in the entire bottom culm, we fastened steel clamps around the diameter of the bamboo and leave left to dry (may take several days).
|Image:Bamboo holes.jpeg| Digging Holes
|5| We then dug holes that were wide enough and deep enough so that the bamboo poles will sit securely in the ground.

== Conclusions ==
===Testing results===
The finished shade structure consisted 2x4s lashed to bamboo poles which were filled with concrete and rebar and then sunk into holes in the ground filled with concrete. On one side of the fogon corrugated zinc panels were installed, and on the other side of the fogon the team built a bamboo truss. The team installed billboard vinyl panels over the bamboo truss by nailing down the vinyl to the zinc roof, and at the other end of the panel the team lashed onto the bamboo posts. On the side of the fogon with the billboard vinyl, it will be necessary to install more bamboo support beams underneath the vinyl to ensure its security and flatness.
 
===Lessons learned===
If the project had not been time sensitive, we would have used properly cured bamboo for the beams. In addition, we discovered that our first batch of concrete that we used to sink the posts into the ground was at an incorrect ratio of sand to concrete and so we surrounded the posts with chicken wire and made more concrete into a cone shape for better support of the beams.
 
=== Next steps ===
The finished shade structure consisted 2x4s lashed to bamboo poles which were filled with concrete and rebar and then sunk into holes in the ground filled with concrete1. On one side of Testing the fogon corrugated zinc panels were installed, bamboo for moisture content while watching its durability and on the other side of the fogon the team built a bamboo truss. The team installed billboard vinyl panels over the bamboo truss by nailing down the vinyl strength to determine whether the zinc roof, and at drying time was sufficient or whether it was an issue in maintaining the other end integrity of the panel the team lashed onto the structure over time.<br>2. Adding more bamboo posts. On support beams under the side of billboard so the fogon with the billboard vinyl, it will be necessary to install lay more bamboo support beams underneath flat.<br>3. Checking the vinyl to ensure its security and flatnessthere has not been tears in the panels. == Team ==The Las Malvinas community center shade team from the Summer 2014 program consisted of: *[[User:Bcreager|Baron Creager]] (Humboldt State University) - bmc83@humboldt.edu*[[User:Cjf336|Caitlin Faber]] (Humboldt State University) - cjf336@humboldt.edu*[[User:Caelidh|Caelidh Liddell]] (Humboldt State University) - crl307@humboldt.edu*Marjorie Casado (UNIBE) - marjocalara@gmail.com ==References==See [[Las Malvinas community center shade/Literature Review|Literature Review]] [[Category:Practivistas_Dominicana_Program]]
