Nothing in a scheme prompts periodic work
Routine cleaning has a natural feedback loop: it stops happening and somebody notices within a week. Periodic work has none. A hardstand deteriorates over years, nobody can point to when it changed, and the absence of the work produces no event that reaches a committee agenda. It simply does not happen until the accumulated condition becomes obvious. There is no complaint, no incident and no agenda item to prompt anybody.
That is why it needs a document rather than a decision. A dated programme listing each item, its interval and when it was last completed creates the prompt that the scheme does not otherwise have. It takes one page and it is the difference between planned expenditure and a large unbudgeted job at the point where the estate has become visibly neglected. One page creates the trigger that the scheme's own processes never will.
