[quote:e7befbbf51="Hello Kitty"]Thank You liuh. Do you know their sequence ? Start from Upper to lower ?
From Tower 6 to Tower 1 ??
How many days in advance to inform you ??[/quote]
It's from top to the bottum and each tower has separated team to work on both D and E flat at same time.
I've requested them to provide 2 weeks advance notice. Right now they should finish 4x by end of this month. For each month they can handle 10 floors. So you should contact them earlier to try to get a estimated day from them. They should be able to finish entire replacement by end of this year.
