Well talk is cheap Mark What I can tell you from firsthand observation and interaction with the contractors doing the trenching is that the pavement may look ok after they have tarred it but it is going to sag as they are not prepared to fix any of the broken drainage pipes. After the heavy rain storm on the infamous Wednesday, just about tall the drain pipes in Howe Street showed signs of leakage and sinkholes (mini little ones) The contractor has just piled up the gravel again and will compact and tar.
The leaks are still there and will causing sagging in the pavement. Just have a look at the pavements were DFA/Plessey/Neotel ravaged then years ago. The sagging is bad and there were no obviously visible leaking pipes. Good enough for government work still holds true no matter what Councilor Chapple may guarantee or may have been gaurenteed. He is part of government after all.
