Today's award goes to Spanish infrastructure-building company AZVI. A tip o' the hat to Australian reader Snoggeramus for sending me the link to this article.
IT WAS meant to be Chile's first drawbridge.
Instead, it was built with at least one traffic deck upside down, so opening day will have to wait, officials said.
. . .
Inspectors getting ready for opening day found that either one or two of the traffic decks were installed backwards, authorities said, though they presumably know their drawbridges even if the old technology is new to Chile.
There's more at the link.
How, precisely, do you install a bridge deck upside-down? I wouldn't have believed it was possible!
