Team 2220 worked with one of our sponsors, Skyline Exhibits, last year (2012-13) to design a new pit for our team. A large amount of the new pit structure uses SkyTruss (
http://www.skyline.com/small-island-...stems/skytruss) a modular, flat-packing truss system they use for exhibits. It's a very nice system, but if you were to buy our pit new, the estimated cost they gave us was $20000 (yes that's the right amount of zeros). Fortunately they were able to find used rental components for most of it, reducing the cost for the team to $1000. Truss is awesome-- it's so flexible.
