Delivering to Rosebery premises whose occupied days move week to week

Some work is needed regardless of occupancy: amenities that are used by anyone present, waste that generates odour whether or not the space was busy, entries and any area with external exposure. Other work scales directly with use: floors in the working areas, kitchen and breakout spaces, meeting rooms and detail work on surfaces that only get touched when people are there. Recognising which category each task falls into is most of the design work.

Separating those two makes a variable arrangement possible. The fixed element runs on a schedule and is not negotiated. The variable element is triggered, and because it is a defined and pre-priced set of work, invoking it takes a message rather than a quote. Building it that way is what makes flexibility practical instead of aspirational. Pre-pricing the variable element is what turns flexibility from an idea into a usable arrangement.

A trigger that requires somebody to remember will fail. So it is attached to something that already happens: a weekly schedule the client publishes, a booking system, a standing message from a studio manager on a set day, or in the simplest arrangement a default assumption with an opt-out. The last of those often works best, because doing nothing produces the more expensive but safer outcome. A default that errs towards the safer outcome is more robust than one relying on memory.

The crew's observations are the backup. A cleaner arriving to find a space that clearly had twenty people in it can escalate the attendance for that night within an agreed limit, and a cleaner finding an untouched studio can reduce it. Giving the crew that latitude within bounds is more responsive than any notification system, because they are the ones actually looking at the building. They are the ones actually looking at the building, which no notification system can replicate.

A variable arrangement only works if the record is accurate, and the incentive runs one way. So what was performed on each attendance is recorded, and the pattern is reviewed periodically against what the client expected. That review protects the client from an arrangement that quietly defaults to the higher level, and it protects the crew from being asked to deliver the higher level at the lower price. Recording what was performed is what keeps a variable arrangement trustworthy.

It also identifies when the arrangement has stopped fitting. A studio that has become consistently busy no longer needs a variable structure and is better served by a fixed higher-level schedule. Recognising that early is better for both parties than continuing with a mechanism that is being invoked every week and adding administration for no benefit. Recognising that early avoids administering a mechanism that has stopped earning its place.
