One of the things I've been working on this month was sizing the stairwells for the new ship. I've never fully appreciated the work that goes into determining the dimensions of a stairwell before. This is an incredibly complicated process. I've made a monster spreadsheet just to figure out how wide the stairs have to be. Then there's the slope of the stairs, the area of the landings for each deck, the width of the doors to the landings... and all of this has to be determined for both day and night conditions and designed for the largest of the two requirements.
Well, I guess it's a good thing I like puzzles!
