Revised Site Plan

For you reference: the new pod dimension is: 3.66m x 7.27m. Maybe we should think about rounding those dimensions for ease of construction.

Site Schemes

Here are some new site schemes. The small field measures 60x+/-85, large field measures 65x110. All measurements fit with in suggested ranges for youth and adult size fields. Our new distance between the small field and the pods measures about 4.9m which is about 15 ft, perfect I think. Note the purple rectangles indicate a location for the mobile aids unit. I think rotating the field offers some nice site relationships with the main road/the foot paths/the Africa centre/and the mountain as a backdrop for the field from the stands. I also mirrored our L shape for some of the same reasons as well as it allows for people to walk through the market and gathering space to get to the stands.

Re:Site Plan
So after considering the last scheme and (with Kate's help) coming to the realization that the benches and stands were 18m away from the field... I re-considered the layout. Same idea as other schemes we have come up with some idea of tranformability.


Re:Rainwater Harvesting
Here a some great links:
http://www.rainwaterharvesting.org/urban/Components.htm
http://www.eng.warwick.ac.uk/DTU/pubs/wp/wp55/index.html
http://www.solarengineering.co.za/rainwater_htm1.htm

So this is what I figured based on what we have so far:
Water collected per:
Year: 1125 m2 (area of roof for small field) x .825 (ave rain fall for Somkhele) x .90 (efficiency) =835 m3
Day: 835.31/685 = 2.29m3 (2288.5 liters)
Person: 2288/20 (Liters/day) = 114 people

In our area the population is 200-300 people per km2... so theoretically we could supply enough water for about half the people in the area of our field (from what I read 1 Km is about as far as someone could carry enough water for each day (still three trips)). That is if you can collect all the water that falls with 10% runoff for contaminated water. I think there is also a lot of potential for that 10% that is not drinkable... such as weeping it into the field. Im workin on it.

I am also working on the barrel size based on the calcs above: here are two options.


Re:Material Considerations:
check out this link for great gutter suggestions:

There is a great example of a plastic tarp with thaching over it.

Also: I looked up 4mm plastic sheeting... it is basically the equivalent of plaexi-galss. Im not sure if that is what we are really looking for. Sheet metal while not a great option will provide a 90% efficiency that we a re looking for for water collextion. I also looked for product/cost info about the roof membrabrain (fabric) idea I had last weeked without much luck. So basically Im no help.

Re:Presentation Materials
With 19 days left we really need to start making some decisions and run with them. I would like to also include a 3d axon diagram of our water collection system if we have time. Talk to you guys tomorrow!

Re:SitePlan

Ok so here are my latest thoughts on the site plan:

Phase I:
A- Stands/Market
B- Gather/Bath/Info
C- Maybe Market
D- Team A
E- Team B
Phase II:
A- More Stands
B- Gather/Bath/Info
C- Market
D&E- Team A
F- Team B

Welcome Adair

Welcome to our newest member... "adair". Sounds sexy ;)

In other news I am celbrating a small victory in finally figuring out how to get rid of the double dashed line under our profile names... trial and error fails me not.

Also... Arch for Humanity has a fun falsh up that explains the rules of soccer, it also gives some good dimensions... when stop being throughly amused with the animation i will write them down.

I have been doing a fair ammount of research about water harvesting... since our compition will most likely be over before anyone reads this... i will tell you about it via human interaction.
