All:

 

            About a month ago (September 9th) we issued a NOTAM closing
Taxiway Delta because of a hole in the asphalt and a fairly large void
under the pavement around the hole.  This section of pavement sits right
above a storm drain line, which means we likely have a broken joint in
the drain line.  The line is pretty big, I think it's at least a 60-inch
RCP, maybe even bigger than that.  Does Public Works have any equipment
to TV that line, would you even recommend we do that?  We need to get
this fixed.  I expect the fix will include saw-cutting and removing a
section of asphalt, digging down to the line and patching the joint,
filling back over the line, and finally replacing the asphalt.
Unfortunately, the hole is on the runway side of the holding position
markings, but we can deal with that by issuing appropriate NOTAMs and
providing escorts for contractors.  The main question is how do we want
to proceed towards getting this repaired?
