18 ft. of snow is way over the design standards for the structures. Who would have ever thought they would get 18 ft. of snow? Hence the problem. It also depends on how wet the snow actually is.

One of the years I was in Alaska we had a lot of accumulated snow. During a engineering department head meeting we got sidetracked into a discussion of how to calculate the snow load on our roofs and decide if we needed to be shoveling it off.

After a ridiculous amount of wasted time, figures of density calcs and such, the Process Chief, who had been silent this whole time, spoke up and said the current snow load on his roof was exactly XX.X lbs/sq ft and he wasn't concerned (less than half of what should have been close to a limit).

We turned to him and said how do you know that?

He said yesterday he used a shovel, cut off 6” x 6” of snow, put it into a bucket and weighed it.

Sometimes engineers just make it hard. It's our nature.
