Isn't this rather dangerous?
On one of my projects (a gas compressor building about 15 feet by 30
feet with dynamically applied loading) I sent a geotechnical engineer to the
site to prepare a soil report. They drilled one test hole near one end of
the building and found "soft weathered bedrock about three feet from the
surface" The contractor started his excavation near the other end of the
building and found 30 feet of a material we commonly refer to as "bird
droppings" (in slightly less socially acceptable terms, course) resulting
from an abandoned, and forgotten, storm sewer line.
I think I would like to see some site specific evaluation or
confirmation of conditions, even if it's only a critical observation by the
structural engineer, architect general contractor or building inspector.
Regards,
H. Daryl Richardson

Dennis-
Burbank had (and hopefully still has) the City divided into 4 quadrants and
had soil tests done for each. They then provided the data for anyone to use
upon paying a small fee (less than $100 as I recall) to use the data and to
repay them for having the tests done. I believe this was only for
residential and small commercial projects.
It has never made much sense to me for an owner to have to pay about $2000
for a soil test for a residential addition when one was done a few months
earlier at a site next door or a couple of houses away- and this is what is
required in some cities.
