Brian - I'm a structural engineer. Currently I'm working on a funny mixed use building for a big DIY firm - it's part car park, part office, and part mock store where they figure out how they're going to arrange the stock in the stores throughout Britain.
Basically, we've been going hell for leather to get the first bits of steel approved so we can get our guys fabricating it, but to the detriment of the rest of the structure. In essence it "stands up" - the philosophy is sound, but we haven't designed the steel that makes up the ramps that serve the car park on floors 2, 3 and 4. I started it late last night, and I've taken our design laptop home this weekend to do more on it. I've even cancelled a trip to Durham to see my old uni friends to do this. My boss friggin' owes me for this. (The work laptop is this AWESOME HP monster though with uber-mega-display and about 14 million rabbitfeet of RAM. I'll take some screenies of the design software later today)
Oh, and now I've just remembered the Architect has moved about 80% of the service voids in the zone we had signed off for construction, so I have to move all those around, redesign any failing members and pass all this off onto our already overworked draughtsman who may eat me.
