Dear SEAINT friends:

Yesterday's New York Times reported that the original documents from the
time of construction of the Titanic shows that the engineers used
sub-standard iron rivets in the construction since sound steel rivets
were hard to get
Then I  found the following e-mail in my inbox from a dear friend who is
a scientist and faculty member in Division of Epidemiology of a
prestigious university in Midwest:

In my working on several very public projects, starting with the San
Francisco Oakland Bay Bridge in 1989 on to my present I-35W and Mac
Arthur projects, I have heard over and over the frustration and horror
of many non-engineers upon coming across the lack of respect for human
life and public safety on the part of some engineers and the presence of
what I have termed as "moral corruption" on the part of again some
engineers who protect the faulty performance of their fellow engineers
at the expense of public safety. I may have said this before, but, since
it is so dear to me I will repeat again.  A dear friend of mine in the
business school here with whom I work at the Center for Catastrophic
Risk Management at UC Berkeley, after the the Katrina disaster told me
that "you engineers think that the planet earth is un-inhabited!" .
Initially I kind of reacted trying to defend ourselves, but, then after
looking back to my exposure to and involvement in investigating
disasters for about 40 years now, and specially resent performance of
engineers in the case of design of new East Spans of the Bay Bridge by
Caltrans and private sector consultants and contractors, Investigation
of the collapse of the Murrah Building, WTC towers and New Orleans
Levees by the ASCE Building Performance Assessment Teams, the collapse
and reconstruction of the Mac Arthur Maze by Caltarns and private sector
contractors and consultants
and now the case of I-35W tragic collapse and its investigation by NTSB
and private sector consultants, I have concluded that she is absolutely
right and engineers, at least most, think that planet earth is
un-inhabited!.  If you do not agree with me let us see how many times
when designing a structure, a member  or a connection, it has crossed
your mind what happens if this structural element that I am designing
fails and how many people will get killed or injured?    You may have
taught of losing your job, losing your license, losing your reputation,
but very few of us think of consequences of our  design in term of
immediate and direct loss of lives of loved ones of someone else.

You know,  the downward arrow that you put on that beam and write next
to it say "LL=45 kips" actually means the weight of 300 human beings
right there and if that beam fails, hundreds can get killed or injured. 
Don't you think it is time for us , specially in structural engineering,
to accept that not only the planet earth is inhabited but the
inhabitants of this planet live and work in our structures trusting that
our foremost priority is their safety. Please do not tell me that of
course in structural engineering we put safety first, may be most of us
do, but, some do not and those of us who do have a responsibility and
duty to make sure those few irresponsible individuals are filtered out
of these great professions of civil engineering and structural
engineering. The starting point can be this case of the ASCE's
investigations of the Katrina catastrophe and the WTC towers collapse

It is up to  all of us to save the reputation of  our profession and
clean up our professional organizations of "morally corrupt" officials
and members so that the public can trust us again as the dedicated civil
engineering and structural engineering professionals who are truly
dedicated to public safety and not to protecting their fellow engineers
and friends at the expense of public safety.

Please remember the saying that:  you can fool some people forever and
you can fool everyone for sometime but you cannot fool everyone forever!
