Bar commissioning

Nine phases from empty shell to open doors, with dependencies, responsible roles and a definition of done for each.

From an empty shell to open doors, in the order the dependencies allow. Each phase names who is accountable, who signs it off, what goes wrong here, and what that failure costs the phases after it.

No amperage, no phase requirement, no pipe diameter, no fall, no duct size, no flush volume, no levelling tolerance and no temperature appears anywhere below, in either language. Each of those is set by a code, by a manufacturer's instruction for a specific machine, or by a hazard analysis for a specific menu in a specific building — and a number printed here would be read as a specification by the one reader who then does not go and ask. Every phase names what determines its requirement and who confirms it instead, which is the part that transfers between sites.

1. Site readiness and the frozen schedule

A shell whose services reach the points the bar will actually use them, and an equipment schedule that has stopped changing. Everything after this phase is designed against that schedule, so a late substitution invalidates work already carried out and already paid for.

Building consent, the fire strategy and food-premises registration set what the shell must be before fit-out begins. The contractor holds the drawings and the local authority governs; nothing on this page substitutes for either. (Contractor / Operations lead)

• The equipment schedule is treated as a draft and keeps moving through the fit-out. · Every service position downstream was set from it. A machine swapped after first fix puts the water where the machine is not, and the correction is chased pipework and re-certified circuits rather than an edit to a sheet.
• The delivery route is measured on the drawing and never walked. · A machine that cannot pass a door, a lift or a turn arrives and stays outside. The delay is not measured in that machine — it is measured in rescheduling every trade queued behind it.

1. The equipment schedule is signed and dated, and every line carries the supplier's own nameplate data for that specific item rather than a class average taken from a comparable machine.
2. Each item's service requirement is written against a marked position on the floor plan, so the plumber and the electrician can work from one sheet without asking anyone.
3. The delivery route has been walked with the largest crate's dimensions in hand, and the narrowest point on that route is recorded.

2. Water supply testing and treatment specification

A test result drawn from the supply that will feed this bar, and a treatment specification written against that result rather than against a machine manual.

The test result governs the treatment train, and the manufacturer's warranty conditions state the water each machine must be given. Where a potable-supply certificate is required, the local authority and the water utility govern. This page states no hardness, no alkalinity and no pressure. (Equipment technician / Operations lead)

• Treatment is specified from the machine manual, or from a test of a different building on the same street. · The train is either under-specified, and scale accumulates inside a boiler nobody can see into until recovery slows, or over-specified, and the venue pays a cartridge cost on a schedule for capacity it never uses.
• The sample is drawn before the supply runs clean, or from a tap that is not on the bar's branch. · Everything specified afterwards describes water the bar will never receive, and the first honest reading arrives once the machine is already running under warranty conditions it does not meet.

1. A dated test result exists, naming the tap it was drawn from and the branch that tap sits on.
2. The treatment specification names every stage and the reason that stage is present, and each reason traces to a line on the test result.
3. The cartridge replacement interval is recorded as the manufacturer states it, on the basis the manufacturer uses, rather than converted into a calendar date the site then treats as a fact.

3. Plumbing, drainage and the treatment train installed

Supply pipework, isolating valves, the specified treatment train, and trapped waste terminating where the schedule says equipment will stand.

Pipe sizing, backflow protection, trap type and fall are set by the local plumbing code and the food-premises requirements, and are confirmed by the plumber who certifies the installation. This page states no diameter and no gradient. (Plumber / Operations lead)

• The drain is placed where the floor allowed rather than where the equipment stands. · A run that crosses the working area leaks where people stand, and the correction is a floor rather than a pipe.
• Isolating valves are fitted behind the equipment position. · Every later service call begins by moving a machine, so the valve goes unused and the shut-off becomes the mains for the whole bar. A cartridge change then takes the venue offline instead of one machine.

1. Every supply point has an isolating valve that can be reached and turned with the equipment in its final position.
2. The installation has held a pressure test witnessed by someone other than the person who installed it, and the certificate is on file.
3. Each waste point is trapped, and water poured at each one has been seen to run away with the equipment in place rather than before it arrived.
4. The treatment train sits upstream of every branch it is meant to serve, and no hot machine remains on an untreated branch.

4. Electrical installation and dedicated circuits

Circuits, isolators and outlet positions installed and certified against the frozen schedule, with every machine isolatable without shutting down the bar.

Total connected load, the supply available at the boundary and the local code determine circuit provision, protection, and whether the site needs a supply it does not currently have. A licensed electrician designs and certifies it and the authority having jurisdiction governs. This page states no amperage, no phase requirement and no load. (Licensed electrician / Operations lead)

• Equipment is selected before the supply is confirmed. · The machine arrives, the supply cannot carry it, and the wait is on a utility connection rather than on a trade — the one delay in this sequence that no amount of labour on site shortens.
• Outlets are positioned to suit the wall rather than the machine. · A lead crossing a wet working surface is a hazard nobody removes once service starts, because by then there is nowhere else for it to go.

1. A certificate exists, issued by the licensed electrician who did the work, and it references the equipment schedule by its signed date.
2. Every machine can be isolated at a point the operations lead can reach without tools and without shutting down refrigeration.
3. No outlet sits where a lead would have to cross a wet surface or a walkway to reach it, checked against the marked positions on the floor plan.

5. Equipment placement and levelling

Every item in its final position and level, with service access preserved, and with the person who will work each station standing in it.

The levelling tolerance is the manufacturer's, and drainage inside the machine depends on it; the same document sets the clearance a service engineer needs. The equipment technician works to that instruction. This page states no tolerance. (Equipment technician / Head barista)

• A machine is set on a counter that is level to the eye. · An espresso machine out of level drains unevenly and reads as a group fault; a fridge out of level does not seal, and the compressor runs against a door that never quite closes. Both are diagnosed for months as something else.
• The unit is pushed back to the wall to gain working depth. · Service access disappears. The first engineer visit becomes a two-person lift, and the interval between services quietly lengthens until something fails instead of being maintained.

1. Every machine reads level on an instrument rather than by eye, in both axes.
2. The head barista has stood at each station and reached everything used during a drink without stepping, and the corrections that came out of that are done rather than listed.
3. Every panel that must come off for service can come off with the machine where it stands.

6. Commissioning the water path

Lines flushed, treatment media run in, boilers filled, and a held pressure test with no loss — all of it before anything is energised.

Flush requirement, media run-in and fill sequence are the manufacturer's instruction for that specific cartridge and that specific machine. There is no generic quantity here and this page states none. (Equipment technician / Plumber)

• A boiler is energised before it is confirmed full. · A dry element is destroyed in the time it takes to notice, and the machine becomes a warranty argument in the week it was meant to open.
• New pipework and new media are not flushed to the manufacturer's instruction. · Installation debris and carbon fines reach the machine and the first cup. The taste fault is blamed on the coffee, and the grinder is adjusted to chase a water problem.

1. Flushing is recorded against the manufacturer's stated requirement for each cartridge, with who did it and when.
2. Each boiler is confirmed full from the machine's own sight glass or fill indication before any power is applied to it.
3. The system has held pressure with no measurable loss over the interval the plumber specifies, and the result is written down rather than remembered.
4. Every joint disturbed during placement has been checked dry by hand rather than by looking at the floor.

7. Energisation, calibration and first extraction

Machines at working temperature and pressure, grinders set against the coffee the venue will actually serve, and a recipe card recorded from what was measured rather than copied from a supplier's sheet.

Brew pressure and temperature come from the machine's own specification and the extraction standard the venue works to; dose and yield come from the venue's recipe, measured on its own scale. This page carries no figure — the espresso calibration tool and the extraction SOP own them. (Head barista / Operations lead)

• Calibration is done on the technician's coffee rather than the venue's. · The recipe card is correct for a bag nobody will order again. The team then treats the card as fixed and the coffee as wrong, which is the reverse of the truth.
• The bar opens on a machine that has been warm for a short while rather than through a full warm-up from cold. · The first hour drifts, the barista chases it on the grinder, and the correction is still in the grinder after the machine has settled.

1. A recipe card exists in the venue's own hand for every drink on the opening menu, with dose, yield and time recorded from the machine that will serve them.
2. The same drink pulled by two people on two different days lands inside the tolerance the operations lead has written down.
3. Every machine has completed a full warm-up from cold, and the time it took is recorded so the opening rota can be built on it.

8. Staff training and dry service

A team that has worked the real layout under a timed load before a customer is in the room, and the layout corrections that rehearsal produced.

The service model — order intake, ticket flow and the wait the menu implies — determines what the rehearsal has to reproduce. The operations lead sets it and the rehearsal tests it. (Head barista / Operations lead)

• Training is delivered as a demonstration rather than a rehearsal. · The team has watched the bar work and has not worked it. The first real rush becomes the first time anyone discovers that two people cannot pass at the milk station, and by then the counter is built.
• The dry service is run at a comfortable pace. · It confirms what everyone already believed. A rehearsal in which nothing fails has tested nothing, and the failures it did not surface arrive later with customers attached.

1. A dry service has been run at the ticket rate the opening forecast expects, with every station staffed as it will be staffed.
2. The layout changes the rehearsal exposed are done, and the rehearsal has been repeated after them.
3. Every member of the team has produced each drink on the opening menu to the recipe card under observation, and the observation is recorded.
4. Cleaning and closedown have been rehearsed as well as production, because the first closedown is otherwise performed by a tired team that has never done it.

9. Food-safety sign-off and opening checks

The controls an inspection examines, in place and already generating records, plus the opening checklist the bar will use every day after this one.

The hazard analysis for this menu determines which controls are critical and what each is monitored against. The food-safety officer writes it; the local authority registers and inspects the premises and is the only body that can say the venue may open. Every temperature, concentration and interval in that plan comes from the plan itself or from the product label, and none of them appear here. (Food-safety officer / Operations lead)

• The food-safety file is written to pass an inspection rather than to run a bar. · It describes a venue that does not exist. The first time a record is needed for a real incident, the plan turns out to describe something nobody has ever done.
• Monitoring starts on the opening day. · There is no record of the equipment holding temperature before stock went into it, so the first cold-chain question has no evidence behind it and the stock becomes a judgement call.

1. Temperature monitoring has been running long enough to show every unit holding through a full closed period, and those records are on file before stock arrives.
2. Chemicals are stored separated from all food, each with its own label present and legible, and the dilution written at every point of use is the one the product label states.
3. Handwash provision is in place, stocked and reachable without leaving the bar, and it has not been used for anything else during the fit-out.
4. The daily opening checklist exists as a single sheet the team has already completed once during rehearsal, rather than a document issued on the first morning.
