I see, that is a shame, so could still be months away if I'm unlucky. Well, thanks for sharing anyway. They're back today working again.
From what I have seen with mine each team is quite diligent on their own task and work through till it is complete, or they reach a sticking point.
Sticking point would be a blocked duct, or a chamber that won't fit. They then report this back and the right team (a surveyor, a duct unblocker, ground works) gets scheduled based on their availability. Once the sticking point is passed the original team get scheduled back on. But each time you are reliant on the availability of the relevant team, and take your place i their queue. They don't hold a slot open expecting team A to finish at x date so team B can take over. Plus the black hole of scheduling doesn't help the nerves.
Plus just because they are doing the bit on your pole doesn't mean they have done the bit upstream. And if even if that bit goes to plan doesn't mean the next bit will.
Best advice I would suggest is get out with kettle in hand, biscuits if possible, and talk to the guys doing the work. Ask them how it works, what things are, is it a difficult install or bread and butter for them, mine have all been great. Don't ask them when it will be done, show an interest in what they are doing. We have provided parking for trucks, toilets (we have guest/public ones), tea, offered biscuits (declined). I have the email/phone of one the teams responsible for putting in the fibre, his updates have been great.
You will get a better idea of stages remaining from the guys on site than Openreach's communication system.
(Mine keeps telling me they are going to arrange stores deliveries for the ducting I am due to install - it was delivered October and installed November).
