Juggling I do hope that you've had better news since you last posted.
Things are a bit better with my much smaller project. (Thank you RandomFriend for your advice.) I chased up the scaffolding with the building company dropping hints about getting alternative quotes and asking for definite dates for the scaffolders and other works to start.
There was a bit of a hiccup when I waited in all day for scaffolders who failed to arrive but with RandomFriends advice in mind I then kept phoning the company until they promised that they would arrive the next day. As indeed they did.
The builders did a couple of days work and then disappeared, again, leaving me waiting in all day to no purpose. When I looked at what they'd done it so far it didn't seem to accord with the steps listed in the estimate.
I got onto the company about the builders not turning up saying that I expected them to be there the next day.
The builders then phoned the next day to say that they wouldn't be there until the following day. I asked them to explain what they had done so far and what they were doing next from which it was clear that they weren't following all the steps in the estimate. They then came over and we had a discussion about that, talked in more detail about what was required and why. I explained my concerns and we've come to an agreement whereby they are going to do rather more than they'd planned to, not do one bit of the works listed on the estimate (which they say is not necessary) and that I will have an altered schedule signed by them as to what has actually been done.
Why does it have to be so difficult?
