Team- please review the revised CD set list under the Student Materials Sidebar.
it's time to corral our nomadic construction set. The first submission was incomplete, and while the drawings have evolved nicely with the design, they remain decentralized and inconsistently available for discussion. Please submit the following (no matter its current state!) formatted by Friday evening 6pm via email. Dedicate 45 minutes to organizing your team's fundamental working drawings, schedules, and presentation drawings - and lets see what we get.
CD submission format (each sheet):
- a 24x36 PDF with title block and sheet number, and drawings labeled with scale present.
* all files named: 080501CDs_drawing number_yourfirstname.pdf

Rebar!
Hey all-
I've had a great time helping out so far on your project, thank you all for letting me in on some of the build! It's great to see how well you all work together, and how enthusiastic the community members are that are supporting this process. It's recently become clear to me that this sort of atmosphere does not happen by chance, and you all contribute to making it a great learning and working environment that's open to letting outsiders be part of the process. (It's an added plus to see the project coming together each week. Oh, and learning how to tie rebar was also cool. ) Keep it up, and see you this weekend!

Form-Active Tension Systems/Membranes
Hey guys_
My name is Evan, i'm a colleague of Kyle's and an MSc candidate in the Emergent Technologies and Design Programme at the AA School of Architecture. I've been doing a bit of work with form-active tension systems and hope I can pose a few questions for you to think about while developing your membrane structure:
1. Material behavior - How does the material chosen behave when stressed? For a form-active tension system to work, the surface should be effectively at zero tension - all forces in the system are spread evenly throughout, and the surface is free of folds, creases, etc. The behavior of a membrane system is specific to its parameters, especially the material of the membrane. The only way to find this out is by physical experimentation. And keep in mind, material does not scale linearly, so you want to play with membranes at a comfortable scale, but test the material system 1:1.
2. Connecting the membrane to a compressive member - I assume the membrane is being anchored by posts somehow, but how do the two components meet? Your drawings show a bungee cord connection, but how does the elasticity of the cord affect the overall tension in the system? How do two elastic materials co-exist in a system where stresses are carefully calculated? How can you keep the system at minimal tension if you cannot calibrate the vectors of forces at the connections?
3. I would urge you all to push the configuration of the system. Membranes are extremely interesting, and there isn't a great deal of work out there being done with them. Why connect four corners to four points? What would happen if two membranes connect to each other? how does that point get negotiated in space, and how can that inform the vector forces at other connection points? There is a huge amount of research that can be done on form-active tension systems, and it could be very valuable to experiment with these systems.
You should take a look at Frei Otto's work [books IL23, IL24, IL25]. He has done extensive research in form-finding, including minimal tension surfaces. It could inform your work and give you a good starting point to push your research. Also look at the numerous stadia built with membrane roofs, the work of Heinz Isler, and the recent installation at the Frac Center in Orlean by Ocean North. I've also added a few images of work being done in the EmTech programme with form-active tension systems and how they may be applied [they led to a cable-net bridge construction in patagonia, chile] to get you guys started.
Feel free to contact me with any questions at evanlgreenberg@gmail.com
Good luck!

Rebar
The rebar forms look great! I'm sorry that I missed this past weekend but i'm looking forward to the next workday. When days and times have been decided, i can send out a mass email. Thanks for all your hard work!

Welcome to our blog!
Hello folks-
Welcome to the workshop blog. Primarily, the role of this blog is to coordinate the various components of our project through focused threads, and to serve as the medium for week updates and action lists.
Additionally, We will upload photos, presentations, and relevant studio materials here. Please begin by posting comments to this thread with suggestions re: the layout or material you'd like to see on the blog.
