Working out the real load
The combined headcount of the suites on the floor is the starting point, and it is usually considerably higher than any single tenancy would guess. Visitors add to it, and where any suite sees clients or patients the visitor component can exceed the staff one. An interval set against one tenancy's twelve people will be wrong for a facility serving forty plus visitors.
Trading and working hours matter too. A floor where one suite runs late or opens on a Saturday extends the period over which the facility is used, sometimes well beyond when it is serviced. Establishing the full picture takes a short conversation with each tenancy and produces a much better basis for the interval than any single occupier's view.
