I had a worse case of this a couple years ago. A conduit leading from a national chain restaurant to the reader board was filled with cement. Seems the pipe layer or, form maker made the cement form to hi, or the pipe to low. When the cement was pored guess where the cement went? you guessed it, right down the hole. I had driven three hours from Vancouver to wire and install all the Network equipment in the restaurant then, route the last two cables to the reader board.
My company called the PM for this chain to see what could be done. A plumber used a special heavy duty augur to remove concrete in a metal conduit.
The second time I went to do the cable install, the conduit was STILL not clear!! So, another 6 hours of driving wasted
Third try, the conduit was finally clear of cement and I routed and terminated the cable. Not sure who ate the 12 hours or round trip drive time but it sure was testing my patience.
