Can someone recommend a contractor who can climb a wide but awkward
interior of a masonry & concrete pier (tight in places going up steel
structure according to Kent Diebolt who has been there already), then drill
and photograph with a boroscope the condition beyond, say to a distance of
up to 20 feet from the aperture.  My alternative is to use a power hammer
and hope to smash through.
New York City area.

Thanks.  --Jim Rhodes
