Caro Colega,
Peço desculpa pelo atraso em resposta. A solução dos colegas de biologia
parece interessante. Em anexo envio-lhe as referencias do colega espanhol
responsável do projecto. Acho que seria bom entrar em contacto com ele
directamente para obter as infromações que pretendem os colegas.
Um abraço
Said

Subject: Re: More Help & technical question


I also have a very difficult (difficult and nasty) technical problem
regarding
Barcelona cathedral. We already figured it out, but reality has imposed
itself in a
very contundent way: the problems of the façade and the cimborio, built
during the
end of 19th and the beginning of 20th on the medieval structure, are
caused
by the
extensive use of iron bars, embedded in the masonry joints, and now
unstoppably
corroding. We had seen many cracks which suggested clearly this problem.
Now, after
the radar, the magnetometer, historical documents found and of course,
inspection
pits, we know that the masonry is in reality a sort of "reinforced
masonry"
with a
large amount of iron bars embedded within the joints and anchoring the
different
parts to each other and to the medieval structure.

I will be thankful if you may inform me of possible
experts in Portugal or elsewhere which you know may have faced similar
problems
dealing with advanced corrosion of iron bars embedded in masonry. I
want to
be sure
that the only solution is dismantling and reconstructing (as everybody
here
is
becoming to understand) or if there is any alternative solution allowing
us
to
remove/destroy the metal without damaging the fabric (which I doubt).
Protecting the
existing metal seems almost impossible given the advanced state of the
corrosion.
Even if everybody says that we need to dismantle it, the way to do so is
not
obvious
at all from a technical point of view, not to mention the difficulty in
explaining it
to the city.To make thinks even more difficult, the placement of
scaffoldings
allowed to undercover a wealth on sculptures and ornaments, which are
valuable even
if they are so modern.
