I'm Scenic Designer on our upcoming high school Musical, Grease. Now I have the set designed with a platform that is 16' long x 10' wide x 3' high. The plan is for the pit to to reside on this platform. I figured I would build it from four 4'x8' and two 2'x8' platforms build from 3/4 plywood and 1x6. Now this is going to hold about 12 people plus a drumset, keyboard and a couple amps. I'm curious if anyone could give me any tips on building this so it is solid and safe. I am aware of how to properly leg it with compression legs and bracing but I have my doubts.
