Labs and data halls across San Francisco
San Francisco runs a lot of sensitive rooms in a small footprint, from research buildings full of labs and cleanrooms to life-science suites tucked into office floors.
Computing has its own footprint here too: large data centers downtown, and smaller server rooms and network closets inside ordinary offices. Each of these spaces needs a crew that works by the room’s own rules instead of the building’s general routine.
Your standard, your room map, your records
Your quality or facilities team owns the standard, and our plan is written to it. Many cleanrooms are graded under ISO 14644-1, which sorts rooms into classes by how many airborne particles a cubic meter of their air can hold, and that class drives how often we clean, what we bring inside and what gets logged.
Before the first visit we walk the building with that team and mark each room on a floor plan: its class or zone, the entry and exit doors, the gowning room that serves it and the tasks inside. The written plan then lists frequency, materials and sign-off for every room, so each visit follows the same map.
Controlled rooms run on documentation. Crews initial the cleaning log your quality team keeps for each room, noting the date, the tasks completed and any detail your form asks for, such as the solution used. Anything out of the ordinary they notice, from a damaged tile seal to a spill outside the usual waste points, goes to your contact before the crew leaves.
When your standard changes, or a room is reclassified after a renovation, the plan is revised with your team and the crew follows the new version from the next visit onward.
Gowning and what crosses the line
Crews gown in the order your procedure sets, from shoe covers or boots at the step-over bench through coverall, hood, mask and gloves, and they degown on the way out in reverse. Phones, paper and general building supplies stay on the outside of the line.
Carts and supply bags are wiped down in the gowning room before they go in, and anything that cannot be wiped stays out. Shift schedules leave time for gowning on each entry, so no step gets rushed at the door.
Inside, we use low-lint wipers, cleanroom-compatible mops and buckets, and the solutions your team approves. Tools that serve a controlled room stay with it and never travel to restrooms or offices, and used wipers and mop heads leave sealed in bags along the exit route you designate.
Ceiling to floor, clean side to door
The sequence inside never changes. Ceilings, light fixtures and upper walls come first, then work surfaces, pass-throughs and equipment exteriors, then lower walls and finally the floor, so anything dislodged lands on surfaces still waiting their turn.
Each room is worked from its far, cleanest end back toward the exit, with overlapping strokes in one direction and wipers refolded to a fresh face as they go. Floors are mopped last while the crew backs out of the room, so no one steps across a finished surface.
Pass-through chambers and airlock doors are wiped on both faces as each room is finished, and the crew leaves through the door your procedure names, so the clean side stays closed behind them.
Raised floors, data halls and escorted visits
In a data hall, dust is the enemy of filters, fans and connections. We vacuum with filtered machines, damp-mop with a low-residue solution and wipe the outsides of cabinets and cages where your team allows. Under raised floors, tiles come up a few at a time so the plenum and cable trays can be vacuumed, and each opening is closed before the next one starts.
Perforated tiles in front of the racks are vacuumed on both faces, and tile edges are wiped before each one is set back, so the floor seats the way it did before the visit.
Access runs through your security process. Crews sign in at the desk, wear the badges you issue and work alongside an escort wherever the site requires one. Your operations team picks the visit dates, keeping them clear of change windows and maintenance work.
The rest of a research building
Controlled rooms are usually a small share of the floor. Benches and instruments are cleaned the way your research staff direct, and crews also clean the lab floors, sinks and glass, the door hardware and each waste point, along with the gowning rooms, corridors and airlocks that buffer each suite.
Offices, conference rooms, break rooms and restrooms in the same building follow office cleaning on the same plan. Lab and corridor floors that need scrubbing or finish work can add commercial floor care on a periodic schedule.
Loading docks and receiving rooms, where packaging and street grit first come inside, get a routine of their own, since they sit closest to the outdoors and furthest from the cleanest rooms.
What sets the price for controlled spaces
Controlled-environment work is quoted for each site after a walkthrough. Room classes, gowning time per entry, the frequency your standard requires, dedicated tools and consumables, raised-floor area, escort time and overnight or weekend access all shape the figure.
Office and support areas are priced on their own line, so the quote shows exactly what the controlled rooms add. Invite whoever owns your cleaning standard to the walkthrough, so the written plan is ready for their sign-off.
Rooms cleaned daily and rooms on a weekly or monthly cycle are listed separately, so the schedule and the price both follow what your standard asks for.
A few useful answers
Common questions.
Do your crews work from our SOPs and logbooks inside controlled rooms?
Yes. The plan is written from your procedures, and crews record each visit in the log or form your quality team uses.
Can you clean a server room inside a regular office suite?
Yes. Server rooms and network closets get filtered vacuuming, damp mopping and exterior wipe-downs, scheduled with your IT contact so equipment work is never interrupted.
What happens to cleaning tools between rooms of different classes?
Each controlled room keeps its own dedicated mops, buckets and wipers, so tools never move from a lower-class area into a cleaner one.
Can cleaning go ahead while experiments are running?
Yes, around them. We clean the rooms that are free, skip any room your team flags as in use and come back once it is released.
Can the office floors in our lab building be on the same plan?
Yes. Offices, conference rooms, break rooms and restrooms follow our office routine and appear on their own line in the same plan.
