Well my recent progress...
The roadworks were meant to start a week ago but nobody turned up, was rescheduled to a week later. This morning a vehicle turned up with a digger, what appeared to be the underground chamber, and various other bits and pieces. They unloaded the digger, did something for an hour or two, then packed up everything (including the barricades and signs) and never returned. They didn't install the underground chamber so I can only assume something has prevented them from continuing at the moment.
I've had a couple of incidents like that.
My confirmed order went in end of June 2018, and is still ongoing. The route to the fibre aggregation node is approx 1.2km, through existing ducts all the way, apart from 34m of new duct identified in the survey.
In the first few months they were dealing with blocked ducts along part of the route nearest me. At one point they had to uncover a buried box, which was dug up and reinstated twice.
Then they had to install the new duct. In October they came along, barricaded the area and dug a small test hole, left it like that for about two weeks, then put a temporary filler in and removed the barricades. A couple of weeks later they came back and put in permanent filler. A few more weeks after that they came and dug it all up again to do the duct installation for real.
I am told the problem was with the wording on the original permit, which was unclear whether the work was in footway or carriageway.
They are now working further back along the route, and keep discovering new problems. December update identified another stretch of footway with duct blockages, requiring multi-way traffic signals (now scheduled for mid-Feb). Then in January they identified that a further 164m of new duct would be required, due to congestion and multiple blockages - not yet scheduled.
It's great that they're doing all this work, but it would have been so much faster if they'd identified all the problems along the route when they started!
