I can do pipes, a building frame, a construction fence and bundles of wood. I can't really think of anything else to add. I suppose I could do a big interior crane, but you wouldn't be able to move it, and it would seriously bump up the release time because I want it to actually look good. I'll have to study cranes and make a few drawings. I'll need to get Constructor working too, because Quark doesn't like aligning things to a grid much, which is a really dumb thing for a modeling program not to do. I'll start working on it tomorrow, and get a beta screenshot out by Thursday, if I get all this paperwork done...
I just did some calculations. Just the treads of the crane are 50 minifigs, 250 1x1s, 1.8 meters, or 6 feet.... The crane is about 1500 minifigs, 7500 1x1s, 57 meters, or 187 feet tall.
What scale should I use? Should I use full scale? Should I scale it to the minifg? Something in between? Because right now, this thing is going to be huge. It would take you a few minutes just to ski down the boom at the current scale.
I'm thinking somewhere between 50% and 75% scale right now.
