Mission-Critical Control Rooms & Operator Centres
Modular control rooms are sized on the worst shift, not the average one — the night an incident fills the room with people who all still have to work.
Decision Rooms
Four decisions that shape the room
Worst shift
How many people are in this room when something goes wrong
A control room is not sized on its normal occupancy. It is sized on the shift where an incident has pulled in a supervisor, a maintenance lead, a contractor and somebody from safety, all of them standing behind seated operators who still have to work. Count that room honestly at the briefing, because it is the only count the building has to survive.
Counting the worst shift changes more than floor area. It changes the circulation behind the desks, the number of doors, the size of the room people are sent to when they are talking loudly, and the air the space has to handle when it is full rather than staffed. All four are cheaper as a decision than as a modification.
Sightlines
What every seat has to see, and from how far away
The shape of the room is set by what must be read from the furthest chair — a display wall, a mimic, a set of screens, or a window onto the process itself. Decide that first and the depth, the width and the ceiling height follow from it. Decide it last and you get a rectangle that somebody has to sit sideways in.
Continuity
What has to keep running, and who has specified it
Continuity of power, cooling and communications is designed by your engineers against your operation’s requirement, and it is quoted as an interface rather than assumed inside a building price. We publish no availability, redundancy or uptime figure here for any building. What we do is make the room able to accept what your design says it needs.
What is loose
Consoles, displays and automation are somebody else’s order
Operator consoles, display walls, chairs, the automation system and the communications fit are designed and supplied by specialists, usually before the building supplier is chosen. This building is drawn around them and provides for them. Which of them your order includes is agreed at the start, because every one has a lead time longer than the assembly of the room.
Being drawn around somebody else’s equipment has one rule: their drawings arrive before ours are frozen. Console footprints, cable entry points, the weight and heat of the display wall and the cabinet schedule for the equipment room all change the building. Late is not fatal, but late is a variation, and it is priced as one.
Where the room sits
Where the room stands is an operational question before it is an architectural one. Close to the process, and an operator can walk out and look at what the screen is telling them. Away from it, and the room is safer, quieter and slower to reach. Your risk assessment settles which of those matters more on your site.
Entry is controlled and that begins outside the door. Who may come in, who may come in escorted, where a visitor waits, where a contractor signs in and where deliveries stop are all decided before the plan is drawn, because a door added later to solve one of them usually lands exactly where somebody is sitting.
There is also the question of what the building has to survive around it. Vehicle movements, plant noise, dust, vibration, drainage and the direction weather arrives from are site facts collected in the survey. They belong to your plot rather than to a product page, and they are the reason two rooms with the same brief are not the same building.
How the shell goes up
The shell rises in a legible order. Steel is fabricated to the drawing and stood on your ground; roof and wall components, ceiling, doors and glazing come in flat and banded; the envelope closes in the sequence the drawing sets, and the fit-out follows it. Nothing habitable is ever transported to the plot.
On an operating site the useful consequence is the load on the road. What arrives is banded material on ordinary transport rather than a finished box needing a closed route and a heavy lift, so the work fits around traffic that cannot stop. That is often the difference between building this year and waiting for the next shutdown.
Cable is the other consequence worth naming. A room full of systems is a room full of containment, and dry-fixed construction lets a panel come off when the third system arrives after handover. What the building is finished in is chosen against your estate’s standards and is not named on this page.
Desks, sightlines and quiet
Everything inside is arranged around a seated eye line. The distance from the furthest chair to what it must read sets the depth of the room; the width of the console run sets the width; the height of the display and the services above it set the ceiling. Change any one of those late and the other three move with it.
Noise is the complaint nobody puts in the brief. A room with hard surfaces, several conversations, radio traffic and equipment fans becomes tiring long before it becomes loud, and tired operators are the risk the room exists to reduce. Acoustic treatment, a separate space for the conversation that has to happen out loud, and a door that closes properly are all plan decisions.
Light is the second one. Screens want low ambient light and people want daylight, and the compromise is designed rather than argued about later: controlled glazing, indirect lighting, and the position of any window relative to the display. A blind installed after handover is the evidence that this was decided too late.

C01
The door through to the equipment room
The console run and the display wall
The fourth panel is the wall everything is arranged against. The display sits at the height the furthest seat can read without lifting a chin, and the console run curves so no operator is looking at another operator’s back. Between them is the distance the sightline decision produced, and it is the room’s real dimension.
Behind the consoles the floor or the ceiling carries the cable to each position, brought up inside the desk rather than across it. A spare route is left at each seat, because the position that is never altered is the one nobody has commissioned yet.
At the end of the run a door leads through to the equipment room, close enough for a short cable and far enough that its fans are not heard at a desk. Anyone walking to it should not have to cross in front of a working screen, which is why its position is settled with the layout.
The buyer’s folio
The operations manager’s folio
Four short chapters for an operations manager: why the worst shift sizes the room, what the seated position governs, how the shell is assembled where it stands, and what an operations team settles before anybody prices it.
01The room is a shift, not a spaceWhy occupancy is counted at its worst, where the building sits on a working site, and what has to be true of getting into it.
The words for this kind of room are used loosely. A supervisor’s office with a couple of screens is not one. What this page means is a room somebody occupies continuously, where a failure to see or hear something has consequences outside the room, and where the building has to keep working when other things are not.
A control room is sized on its worst shift, not its normal one.
That definition is what makes the ordinary decisions expensive. A room that is occupied around the clock is judged on the fourth hour of a night shift, not on the tour it was shown off during, and that is the standard the plan is drawn to.
The room is judged on the fourth hour of a night shift, not on the day it was shown off.
IN SHORT — Count the incident occupancy, settle the entry logic, and let the site facts come from the survey.
02Desks, sightlines and quietWhat the seated position governs, why noise is the complaint nobody predicts, and the small rooms that make a long shift bearable.
Around the room sit the spaces that make a twelve-hour shift bearable and are the first things dropped from a brief: somewhere to eat, somewhere to wash, somewhere to brief, and somewhere to put a person who needs to make a phone call. Each is small, each is easy at plan stage, and each is impossible to add afterwards.
Noise is the complaint nobody puts in the brief and everybody makes afterwards.
Equipment rooms are the other adjacency. Whatever cabinets, network gear and continuity plant your systems need has to sit somewhere with its own access, its own cooling and its own noise separation from the people. Where that room goes is decided with your automation and IT teams, not by us alone.
A blind fitted after handover is evidence the glare was decided too late.
IN SHORT — Eye line, acoustics, light and the small rooms — all four settled on the plan, none of them afterwards.
03Made on site, from componentsThe frame and the panels, why the method suits a running plant, and the wall the whole room is arranged against.
Engineering for the shell and its fixings is done by a licensed professional on the project, to the loads and site conditions your engineer has set out. We publish no structural, wind, seismic or blast figure. Where your operation requires one, it is a stated requirement in the brief and it is designed to, not claimed here.
What arrives is banded material on ordinary transport, so the work fits around traffic that cannot stop.
Beside the drawings we draw up a responsibility matrix with you before anything is ordered. Power and continuity, cooling, fire detection and suppression, access control, cameras, communications, network containment, the consoles, the display wall and the automation fit each take one row, and each row names who designs it, supplies it, installs it, tests it and witnesses that test.
The position that is never altered is the one nobody has commissioned yet.
IN SHORT — One method, one wall to work from, and one named owner against every system the room depends on.
04What is settled before anything is madeWhose drawings arrive first, the inputs a quotation needs, when the sheets are drawn, and the claims this page will not make.
The inputs are specific. The shift pattern with the incident count, what has to be seen from the furthest seat, the console and display design if it exists, the equipment and its heat, your continuity requirement, the site survey with its access and noise conditions, and the date the operation needs the room.
Their drawings arrive before ours are frozen. Late is not fatal, but late is a variation.
The workshops that make these components stand behind more than a hundred projects, and their programme once assembly starts runs sixty to ninety days. Each figure is restated for the building in front of us when we quote. Neither says anything about a control room, and neither covers integration or testing.
Integration and testing belong to the specialists your operation appoints and run on their programme, after ours. Saying so early is not a disclaimer; it is the only way the two programmes can be laid beside each other and the real handover date found before somebody publishes an optimistic one.
We do not claim resilience that the building cannot demonstrate.
We do not claim a room like this can only be built this way, and we do not claim resilience the building cannot demonstrate. What recommends this method is a live operation, a site far from labour, and a programme that has to fit inside a window somebody else controls.
IN SHORT — Seven inputs, one matrix, two supplied figures — and sheets once a design is chosen.
What an operations team asks first
Do you supply the consoles, display wall and automation system?
Not by default. Those are designed and supplied by specialists, often appointed before a building supplier is. The room is drawn around their equipment and provides for its weight, heat, cable and access. If you want any of it inside one order, say so at the briefing; the responsibility matrix records the answer either way.
How many operators does the room seat?
There is no default, and a supplier who offers one is describing a product rather than your operation. The count comes from your shift pattern and, more importantly, from the incident occupancy — the people who arrive when something goes wrong and stand behind seated operators. Give us that number and the room is sized against it.
What availability or uptime does the building provide?
None that we state. Continuity of power, cooling and communications is designed by your engineers to your operation’s requirement, and the building is made able to accept it. We publish no availability, redundancy or resilience figure for any building on this site, because that figure belongs to a system design nobody has done for you yet.
Can it be built beside a plant that is running?
The method suits it. Components arrive banded and flat on everyday transport and the room is put together in position, so no closed route and no heavy lift over live equipment is needed. The access route, the working hours and the permit conditions are fixed with your site ahead of any programme.
How is noise and heat handled inside the room?
As a brief, not as a specification we hand you. Equipment heat comes from the schedules your systems teams hold; the acoustic requirement comes from how the room is used and how many conversations happen in it at once. Both are stated in the brief, designed by the relevant engineer, and tested at handover by whoever the matrix names.
What has to be in the enquiry?
The shift pattern with the incident count, what must be seen from the furthest seat, the console and display design if it exists, the equipment schedule with its heat, your continuity requirement, the site survey, and the date the operation needs the room. Those seven describe the room your operation actually runs.
