Where are your cleaning and security teams right now?

A night supervisor in a twelve-floor tower has nine cleaners and two security officers on shift. She has a radio, a paper round sheet, and a WhatsApp group. When a spill is reported on the seventh floor, she does what every supervisor does: she asks the radio who is nearest, waits, asks again, and sends whoever answers first. That loop costs four minutes. It costs them again at the next call, and the one after that, and by morning the shift has spent close to an hour deciding who should walk where.

The building already knows the answer. It just has no way to say it.

What is indoor staff location visibility?

It is knowing which floor and which room a member of staff is in, live during the shift and in the record afterwards, using the phone they already carry rather than satellite positioning that stops working at the door.

Three parts have to be present. An indoor map with real room geometry, so “room 7.14” means a polygon and not a label. A positioning engine that works where satellites do not. And an operational layer that turns position into something a supervisor does: dispatch the nearest officer, show which rooms on floor 7 have had presence this shift, report response times at the end of the month.

Outdoor positioning is the part people overestimate. The U.S. government’s own figure for a GPS-enabled smartphone is accuracy to within about 4.9 m under open sky, and GPS.gov notes that accuracy degrades near buildings, bridges and trees because the receiver needs a clear view of the sky. A tower is a building made of obstructions. Inside it, 4.9 m under open sky becomes a dot drifting across the car park.

Why do cleaning and security shifts lose time indoors?

Because the work happens in rooms, and the systems managing it only know addresses. Everything between the front door and the room is filled in by radio, memory and signatures.

That gap has a measurable shape. Rooms get cleaned twice because nobody can see that the first pass happened. Rooms get missed because the sheet was signed at the end of the corridor. Escort requests sit in a queue while a supervisor works out who is closest. And when a client asks for evidence, the evidence is handwriting.

Cleaning quality is the half of this that regulators already measure. CDC’s toolkit Options for Evaluating Environmental Cleaning (CDC, December 2010) documents that thoroughness of high-touch surface cleaning is commonly found to be below half of surfaces when it is actually assessed rather than assumed. On the reimbursement side, the HCAHPS survey asks discharged patients how often their room and bathroom were kept clean, and CMS feeds HCAHPS results into the Hospital Value-Based Purchasing Program. Coverage you cannot see is coverage you cannot defend.

Do we need to install hardware on every floor?

No. Mapsted does this without installing any hardware, and you can get room-level accuracy without the need of any hardware. There are no beacons to mount, no anchors to cable, and no batteries on a replacement schedule.

This is the question that decides most projects, and it deserves to be answered before anything else, because the hardware route is where indoor programmes usually die. Mounting devices across a multi-floor building means roof and ceiling access, landlord permission on leased floors, escorted entry into secure areas, and a maintenance line item that never goes away. Then the tenant on floor 9 refits, the ceiling grid changes, and the install has to be partly redone.

Honest about the exception: anchored systems are still the right answer in some settings. A production line that needs centimetre precision on a moving pallet, or a workforce that carries no smartphone at all, is a hardware case. Facilities cleaning and security are not. Those teams already carry phones, already work to a floor plan, and need the room, not the centimetre.

What does room-level accuracy change on a shift?

It changes the unit of work from “the building” to “the room”, which is the unit supervisors, clients and auditors all already use.

A spill is reported in the washroom on 7. The supervisor sees that one cleaner is on 6 and one is on 11, and sends the one on 6 without a single radio call. An escort request comes from the loading bay at 23:40, and the officer two floors up takes it because the system said she was closest, not because she answered the radio fastest.

Room level also changes what you can ask for. “Was the isolation room terminally cleaned after discharge?” is answerable. So is “how long did the oncology corridor go without a presence overnight?” Neither question can be answered by a system whose finest resolution is the postal address.

How do you prove a round was completed?

With an automatic, time-stamped record of presence in each room on the plan, produced as a by-product of the work rather than as paperwork at the end of it.

The distinction matters because a signature records an intention and a presence record describes an event. One is written by the person being assessed; the other is not. Hospitals in the United States have to maintain an infection prevention and control programme under the Medicare Conditions of Participation at 42 CFR 482.42, and a programme is only as strong as what it can show happened.

Write the retention rule down before you turn any of it on. A record that exists for ever is a liability; one that exists for the contract period is evidence.

What does this change for lone worker safety?

It turns an alert into a dispatchable location. A panic button tells you that someone needs help; a room-level position tells the responder which door to open, which is the difference between help and a search.

Regulators have already settled the principle. Under Kari’s Law and Section 506 of RAY BAUM’s Act, the FCC requires that 911 calls from multi-line telephone systems carry a dispatchable location, meaning a street address plus room, floor or similar detail, with compliance dates of 6 January 2021 for fixed systems and 6 January 2022 for non-fixed systems. The regulator decided an address alone is not enough in a tall building. Your incident process should reach the same conclusion.

The exposure is well documented. OSHA’s Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers (OSHA 3148-06R, 2016 edition) recommends alarm systems and personal alarm devices for staff working in isolated areas, and OSHA’s workplace violence page reports, on 2018 Bureau of Labor Statistics data, that healthcare and social service workers absorbed 73% of all nonfatal workplace injuries involving days away from work that were caused by violence. In Great Britain, the Health and Safety Executive’s guidance Protecting lone workers (HSE, INDG73) puts the duty plainly: an employer has to know how a lone worker will summon help and how that help will reach them.

Cleaners on a night shift and officers on a static post are lone workers for most of their hours. They are the people a floor number helps most.

Which numbers should operations report?

Four, and they should all come out of the same record rather than out of four spreadsheets.

Report them at team level by default. Individual presence should be available to the people who need it on shift, and aggregated for everyone else. ISO 41001:2018, the facility management system standard published by ISO, asks for exactly this habit: objectives that are measured, and measurement that feeds a review.

Where does this approach have real limits?

Three, and a buyer who hears them stated is the buyer who stays. Presence depends on a phone being carried and permissioned, on an indoor map that matches the building, and on a privacy position you can defend to staff.

The phone is the first. If a team works without smartphones, or policy forbids the app on personal devices, the scope becomes company handsets or it becomes nothing. Decide that before the pilot, not during it.

The map is the second. A room-level record is only as good as the room boundaries behind it, so map updates have to join the fit-out handover alongside the fire plan. A plan six months behind the building will confidently place a cleaner inside a wall.

Privacy is the third and the one that sinks projects quietly. In the European Union, Regulation (EU) 2016/679 sets data minimisation in Article 5(1)(c) and employment-context processing in Article 88, which together point to shift-hours-only scope, a written retention period, and team-level internal reporting. Where there is a works council or a union, bring them the scope document early. Staff accept a system that routes work to them fairly. They resist a system nobody explained.

How do you scope a pilot in one building?

Pick one building, two teams, four weeks, and one number you have already complained about. Breadth is what makes pilots inconclusive.

Two rules keep the result honest. Measure the baseline before anything changes, because a response time nobody wrote down becomes whatever the loudest memory says it was. And give supervisors the daily view first, since they are the ones who decide whether the system is helping or is one more thing to feed.

If you run cleaning or security across multiple floors and cannot currently say which rooms had presence last night, that is a scoping conversation rather than a procurement exercise. Bring your floor plans and one month of complaints. Book a scoping call and we will walk your building, map it, and tell you what a four-week pilot would actually show.

Frequently asked questions

These are the questions facilities and security buyers ask most often before approving a pilot.

Does room-level accuracy require beacons on every floor?

No. Mapsted provides room-level accuracy without installing any hardware, so there are no beacons to mount, no anchors to cable and no batteries to replace on a maintenance schedule. The positioning runs on the smartphone your staff already carry, against an indoor map of the building. That matters most on leased floors and in secure areas, where arranging install access is slower than the project itself.

Is this different from a lone worker panic button?

A panic button tells you that someone needs help. Room-level presence tells the responder where to go. The FCC’s dispatchable location rules under Kari’s Law and RAY BAUM’s Act draw the same distinction for 911 calls, because a street address is not enough in a tower. Pair the two, and an alert arrives with a floor, a room and a route rather than a building name.

How do you keep this proportionate for staff privacy?

Scope it to shift hours, to the buildings under contract, and to the questions operations reports on: coverage, completed rounds, response times. Under Regulation (EU) 2016/679, data minimisation and the employment-context provisions of Article 88 point the same way. Agree a retention period in writing, publish who can see individual presence, and default all internal reporting to team level rather than to named staff.

What happens when a floor is refitted?

The indoor map has to change with the building, because a room-level record is only as good as the room boundaries behind it. Treat map updates as part of the fit-out handover, the same way you update the fire plan and the asset register. This is the maintenance task that replaces battery changes, and it is a document task rather than a ladder task.

Can security and cleaning share one deployment?

Yes, and that is usually where the business case closes. Both teams need the same two things: an accurate indoor map, and the floor and room a person is in. Cleaning uses it for coverage and completed rounds. Security uses it for response times, escorts and lone worker cover. One map, one positioning engine, two operating reports, one install effort.
