On the contrary, the mason was a pretty fair psychologist. He got one of two
to quit the inspection. His bad luck was that the other was less

		I was lucky.  The owner backed me 100%.  They even supplied
legal muscle. 

		The specifications were not that complicated.  We had
pointing mortar
		thickness, sealant thickness, bonding requirements and the
famous "per
		manufacturer's requirements".  Sealants were insufficient in
		pointing mortar was of insufficient thickness, sealants
failed in bond to
		substrate when tested, glazing sealants failed due to
improper masonry
		cleaning, the manufacturers justifiably refused to accept
the installation,
		and so did I.  The bottom 2 floors looked great.  The next
20 floors up were
		terrible.  I did my sampling from the 3rd floor to the 22nd

		Historic cladding rehabilitation is fun.  It is engineering,
		science, architecture, and old fashioned spit and cuss (if
you hit someone
		from the 22nd floor, you can blame it on a bird).  The
architects did not
		argue over turf, when it required riding the swing stage up
a tall building
		on a windy day.  But then again, I had one engineering
assistant quit and go
		home. When he got to the 6th floor, a mason tried to calm my
		nerves by equating a fall to various sizes of pizza on the
sidewalk.  Masons
		are not very good psychologists.
