Definitely craft is critical but we are in the specification stage and that
allows us to micromanage material selection. Mix that with a suggestion of
Terne Coat II Copper (Freedom Gray), which is something we do not have
experience with, "and" a Parks Project, we are taking the opportunity to
consider all the angles.

Eric,
How about doing some testing of the air quality (acidity) at the
specific location & elevation and projections of future pollution over
200 years? As I understand it re: Live Earth there may not be many
people around to worry about it. Then again, only high elevations of
Minhattan may be evident in 200 years.
I agree w/ Leland about the not any old tin knockers. Can the
not-any-old-tin-knockers be found? Not exactly as if one can google that
and get like w/ Home Depot a result w/in 50 miles, 30 miles, around the
corner. Will they be willing to work in the environment? Will the
'system' lean towards not-any-old-tin-knockers or is there a higher
potential outcome that the system will provide not-quite-tin-knockers? I
agree wholeheartedly on going for the gold standard. I am increasingly
cynical in my old age that a trust in the 'system' leans towards a
potential of screw up at 99%.
My perspective would be to not worry about the performance of the
materials as much as that the contract-bid situation would lead to
supply of mechanics (not exactly their fault) not up to the task and
that a goal of good workmanship and longevity has to take into
consideration just how the final installation might actually happen. If
not the use of a more commonly understood and more easily workable
material by less skilled mechanics might not actually last longer than a
theoretically more durable material installed by functional morons.
I say this with it in mind that I spent a Saturday morning a few
weekends ago down in Little Italy (China Town) up on an 86 lift w/ an
Albanian operator who amidst banging the basket into the wall, getting
the machine hung up, the machine shutting down etc. and his not being
too in-tune with what the little pictures meant on the control panel
(the machine is owned by the company and arrived on their truck) the
whole time saying, "God bless America! How come there are so many
Chinese here? Is this China? God bless America! I am the expert!"
