Albert Street lies between the 1980’s housing rebuild for LeBreton Flats and the yet-unbuilt Sens housing development. The street was dug up, new utiltities installed, and repaved in a much wider format last summer.
You may have noticed this structure promptly popped up last December blocking the middle lane.
What was it doing there?
Ironically, it seems that new 5′ storm sewer under the street had a blockage problem.
The older 2×3′ sanitary sewer deep under the street was not removed during construction, rather it was filled with grout (like liquid cement). Amongst other things, this guards against future collapse of the pipe (s-i-n-k-h-o-l-e), loss of minivans, and saves the cost of digging up the old pipe.
Alas, the old sanitary sewer was connected to the new storm sewer (interconnected sewers … hmmm, just what was being fixed here…) and the grout flowed from the old pipe into the new one.
The new pipe didn’t function so well when congested with cement.
Since December, until last week, workers have been down in the pipes chopping out the cement fill and bringing it up in pieces.
I have no idea how much this cost the city … but lets play with numbers:
6 months x 20 working days each x 6 workers x 8 hours a day x $50 per hour, plus a bit for a truck and paperwork, say $300,000.
Add engineering fees and overhead: $500,000.
