RE: Guano and Bridge Failure

[Subject Prev][Subject Next][Thread Prev][Thread Next]
     Years ago I worked for a company who designed and built canopies for gas stations.  There was a failure of a single column canopy as the pigeons liked one side of the canopy more then the other.  The side they liked had more then a foot of pigeon guano built up on the roof deck.  If memory serves me correctly the column bent over to the point it had to be replaced.
