"Highest occupied level" would raise even more controversy. Is a 'top floor' mechanical level then excluded? Is a high parapet wall concealing rooftop equipment then excluded?

Martin - it's less ridiculous than the current state, where an architect adds a 400+ foot "spire" which counts, but functionally identical antenna masts which have been in place for 30+ years on the Sears (Willis) Tower don't count because they are not "permanent" enough. We need a better dividing line. I'm fine with spires, antenna masts, or even a bolted-on chunk of angle-iron counting for a "tallest structure" title. However, buildings are for human occupancy, so the height for the "tallest building" needs to be based on the highest occupied level in order to avoid the bullsh*t. If you want the roof to count, put an observation platform there.

lots of argument in the age old " mine's bigger than yours" about the tallest building ever built w/o worker injury
