in light of the recession you will continue to see over design and lots of it in the public sector hmmmmm

I think it is also worth bearing in mind that least mass does not equal least cost or least environmental impact: much of the cost/impact relates to the method of construction, which can be far higher for slender structures unable to support themselves until complete. Also note that most of an occupied building's environmental impact occurs during use, not construction, and a high thermal mass can mitigate the operating costs considerably.

As for former professional engineer, I can say that structures are overdesigned to handle things airplanes don't need to worry about, such as earthquakes, hurricanes, and the like.

Considering the liability that engineers work under, they'd rather "Mother" Earth suffers than themselves.
