Allocating work across the year, not into one break
The instinct is to save everything for the longest break, which then cannot accommodate it. A shorter break can comfortably carry a defined set of work: a floor area, a set of rooms for detailed attention, upholstery in a meeting space or high-level work in a corridor. Spreading the programme means each period is used and none is overloaded.
It also produces a better result across the year as a whole. Work that happens only once annually leaves the premises declining for eleven months of the twelve, whereas the same total effort distributed across four periods keeps the condition considerably more even. That matters in an administration block where parents and visitors are present through term and form their impressions from what they can see.
