What actually leaves with the outgoing contractor
The contract ends and the knowledge goes with it. Which door sticks, where the water point is, which tenancy is sensitive about access, which areas were deliberately excluded and why, what the previous committee decided about the rear stair. None of that is written anywhere, and the incoming contractor spends three months rediscovering it while the building looks worse than it did. The building looks worse for a quarter and nobody can explain exactly why.
Very little of that is avoidable by the contractors themselves. It is avoidable by the scheme, which can hold the scope, the boundary map and the standing decisions in its own records rather than relying on whoever was doing the work. A building that hands over a document instead of a phone number transitions in a fortnight rather than a quarter. The documents cost an afternoon and save a season.
