6 Months? To only put the Pipe, Foundation and Cabinet in place.... The hell..... That has to be the worse case scenario right?
It isn't about how quickly one cabinet could be installed if everyone focused on just that one.
It is more about the pipeline of many, many cabinets ... and how full the worklists are for the people working on them, and for the necessary admin tasks to mature (planning periods, roadwork notification periods etc)
Based on the most recent announcements, BT are currently activating 150 cabinets per week. They need a hefty pipeline to keep that rate going.
