Vancouver gets a lot of rain and always has a lot of building construction
going on, especially in the downtown area. For major concrete "pours"
they watch the weather forecast, and builders use large tarps to cover
areas open to the rain, but sometimes there are unforeseen circumstances.
Quite a few years ago when my strata building's roof was being replaced,
the work crew forgot to replace the tarp that was supposed to cover the
hole in the roof overnight, and of course there was a freak rain storm that night.
The sound of running water woke me up and I remember the sinking feeling of seeing
the water pour down from the ceiling into the room where we kept our computers
and other electronics.
We had several large dehumidifying machines running 24/7 for several weeks,
paid for by the builder's insurance, and miraculously, nothing was permanently
damaged. I wish now that we had thought of suing for pain and suffering.
I had nightmares about running water flooding our apartment for several years,
and the memory of that experience still makes me flinch .
A quick search just now told me that the largest tarps available "off the shelf"
in Vancouver go up to 100 feet square, although I'm sure that larger ones
could be pieced together on short notice.
