Yes!  Yep, me over here!

If I have the slightest concern, even over so-called "code-compliant"
measures, I review the "calc" if only to have a good basis for accepting or
arguing against any measure.  I explain in cases where I appear to differ
from the "accepted" or "code" specification, that I am uncomfortable with
the measure or "accepted" specification and, if I am to sign and seal it,
then the proponent of the measure better convince me of the error of my ways
or else he/she can carry the responsibility.

It may be (maybe not!) of interest but two of us here in li'l ol' Victoria
BC have submitted a proposal to our Association that all new buildings
subject to human occupation (without any consideration of size) should have
a mandatory preliminary review by a structural engineer who would then issue
a report identifying items of structural concern.  The Building Official
would then be obliged to make a decision on whether the building should have
engineering or not.  We appreciate that many standard buildings perform
adequately but we (my co-proposer and I) are sensitive to the fact that,
while we have few significant earthquakes around here, the potential for a
devastating one is probably one of the highest in the world.  I don't follow
statistics much so correct me if I am wrong, but it seems that a lot, if not
most, E/Qs occur when people are in their homes.  While in Japan (8 1/2 yrs
over 13+) most of the "heavy" quakes I felt were during the early hours of
the morning.  Kobe, I think, reinforces my opinion.  The great E/Q of the
Juan de Fuca plate in 1700+ also occurred at night.  The 1964 Anchorage E/Q
was at night.  My wife remembers awaking in Port Alberni, Vancouver Island,
during the night to a visage of an ocean surrounding their home where the
previous day there was but a small river and fields (the result of the
attendant tsunami).  We opine that residences are probably going to be
occupied during a quake.  Therefore THEY also should have seismic expertise
applied to them.

Hence our initiative.  I am hoping that our peers around here will not
continue to hide behind our Part 9 prescription.  What I really want

A similar discussion applies to drift snow loading and so on.......
