Somebody has to pay for the corridor.

Deciding which department carries the circulation, the plant room and the empty floorplate is the whole job. These are the tools, the benchmarks and the method behind it.

The model

Office Occupancy Cost Allocation Model

An Excel workbook that takes the numbers you already have — a cost base, an area schedule and a cost centre list — and produces an allocation your finance team will accept. It works one period at a time, so a monthly recharge takes about twenty minutes once it is set up.

Multi-tier gross-up: floor pools stay on their floor, building amenity is shared by everyone
Vacant space, sublet exclusions, shared rooms split by percentage, manual overrides with a reason
One page for the CFO, one page per department head, movement reported space by space
Three reconciliations, ten exception checks and eleven sense checks before anything leaves your desk
Presets for the UK, US, Hong Kong and Singapore, plus a custom mode

It does not read floor plans, take sensor data or post journals. It gives you the figures to post, not the posting.

Why the tiers matter

The client suite on the top floor serves the whole business. Charging it only to the two departments that happen to occupy that floor is not defensible, and they will say so in the meeting. Single-tier models systematically overcharge whichever floor hosts the shared amenity.

The same applies in reverse to circulation: the corridor on Level 3 serves Level 3, and spreading it across the building would undercharge the floor that uses it.

Every non-departmental area therefore states the level it is shared at, and is grossed up to the departments at that level — which is how the enterprise systems do it, and why their output survives a challenge.
