How the Facility is proven before it carries load, and how the emergency procedures are exercised thereafter — the gate ladder from factory test to integrated systems test, the acceptance criteria at each gate, the witness and sign-off regime, and the twelve-month drill calendar.

A facility is not available because it was designed to be. It is available because each system was proven in isolation, then proven together, then proven again under fault — and because the people on shift have executed the failure procedures before the failure arrives. This document sets out both halves of that: the commissioning gate ladder that admits the Facility to service, and the drill programme that keeps the emergency procedures live once it is in service.
Scope is the KOM Oman AI Factory at Knowledge Oasis Muscat — the electrical chain from utility intake to rack, the cooling plant and secondary loops, fire detection and suppression, the security estate, the network fabric and the compute platform. Ready for service is December 2026, and gate L5 is the condition of it.
It is not the test scripts themselves, and it is not a record of tests performed. The scripts are produced by the appointed commissioning agent against the installed plant and the manufacturers' own acceptance procedures; the records accrue as the gates are cleared. Nothing in this document should be read as evidence that a system has been tested.

Commissioning runs in five levels. Each is a gate, not a phase: work on the level above does not begin until the level below is signed off, and a gate is cleared by a witnessed result against a written criterion — never by a contractor's statement that a system is complete.
Every test has its acceptance criterion approved before the test is run. A result is compared against that criterion, not assessed against expectation. Where a manufacturer's tolerance and the design intent differ, the tighter of the two governs.
Nothing is accepted on a report alone. Each gate names who must be physically present, and levels 4 and 5 require Prima's own engineering to witness in addition to the commissioning agent. The customer may attend L5 in full.
A system is not proven by working. It is proven by failing safely: redundancy removed, path lost, supply cut. Levels 4 and 5 exist for this, and a system that performs perfectly under normal conditions has not passed anything.
A failure is a normal and expected output of commissioning — it is the mechanism working. What is not permitted is passing it forward.
| On any failed test | The result is recorded as a fail with the observed values. The test is not re-run until the cause is identified and rectified, and the rectification itself is documented. |
|---|---|
| Re-test scope | The failed test is repeated in full, not from the point of failure. Where the fault is in a shared subsystem, every test that depends on it is repeated. |
| Gate status | The gate stays closed. No level above proceeds, regardless of programme pressure. Escalation is to the COO, and only the COO may authorise a conditional pass. |
| Conditional pass | Permitted only where the open item cannot affect safety, capacity or availability, and only with a named owner and a closure date. Recorded on the gate certificate in full view — never omitted. |
| Procedure feedback | Where a failure reveals that a MOP or EOP is wrong, unclear or unworkable, the procedure is revised under PRM-OPS-2026-001 before the re-test. A drill that finds a bad step triggers a technical revision, not a note. |
The party that installs a system does not sign off that it works. Commissioning is directed by an independent commissioning agent appointed by Prima and reporting to the COO, not to the contractor or the EPC programme. The agent owns the scripts and the results; Prima owns the criteria and the gates.

The first three levels prove equipment in isolation: correct as built, correct as installed, correct as operating. No system interaction is tested here, and passing all three does not imply the Facility works.
| Level | What is proven | Pass criterion | Witness & sign-off |
|---|---|---|---|
| L1Factory witness test | Each major item performs to specification before it ships — UPS modules, generators, switchgear, transformers, chillers, CDUs. Tested at the manufacturer's works under the manufacturer's own acceptance procedure, with load banks where applicable. | Full compliance with the purchase specification and the manufacturer's factory acceptance procedure. Any deviation closed at the works, not on site. | Commissioning agent attends in person for UPS, generators and switchgear. Prima engineering attends or joins remotely. Signed by the agent. |
| L2Static verification | Equipment arrived as ordered, is installed as designed, and is safe to energise. Nameplate against schedule, physical installation against drawings, cable and pipe routing, labelling, earthing, torque checks, insulation resistance, pressure test on all wet systems. | 100% of checklist items complete and signed. Zero open safety items. Discrepancy between as-installed and as-designed either corrected or formally accepted as a design change. | Installing contractor performs; commissioning agent verifies by sample. Prima Facilities Manager countersigns. |
| L3Component start-up | Each item works on its own once energised. First energisation, direction of rotation, protection settings and relay coordination, control response, alarm and trip points, generator start and run on load bank, UPS transfer to and from bypass, chiller and CDU run to steady state. | Every measured value inside design tolerance. Every alarm and trip demonstrated to actuate at its set point — demonstrated, not calculated. Protection settings match the coordination study. | Commissioning agent directs, manufacturer's engineer present for UPS, generators and chillers. Prima Facilities Manager and Engineering Manager witness. Signed by the agent, countersigned by Prima. |
| L1 window | Runs against the equipment order book, ahead of shipment. Long-lead items — transformers, switchgear, generators — are tested first because a factory failure at this stage is recoverable, and one found on site is not. |
|---|---|
| L2 window | Follows each delivery and installation. Runs in parallel across disciplines; no dependency between electrical and mechanical L2. |
| L3 window | Begins when permanent power is available to the item being tested. Electrical L3 must complete before mechanical L3 on any plant that depends on it. |
| Precondition to L4 | All L3 certificates issued for every system in the L4 scope. A single open L3 closes the L4 gate for that system and for anything that shares it. |

The last two levels are where availability is actually established. L4 proves each subsystem behaves correctly when a component within it fails. L5 proves the whole Facility behaves correctly when a system fails — under load, with nothing simulated on paper.
| Level | What is proven | Pass criterion | Witness & sign-off |
|---|---|---|---|
| L4Functional performance | Each subsystem performs as designed and rides through the loss of any single component. Automatic transfer on utility loss, generator pick-up and load acceptance, UPS on battery through the transfer, loss of one power path with A/B load retained, chiller sequencing and lead-lag rotation, CDU failover on a live loop, BMS and EPMS control response, fire detection to suppression release logic, access control fail-safe and fail-secure behaviour. | Design redundancy demonstrated for every single point tested — N+1 held, 2N held where designed. IT load carried without interruption throughout. All timings inside design limits. No manual intervention where the design calls for automatic action. | Commissioning agent directs. Prima Facilities Manager, Engineering Manager and Operations Manager all witness. Signed by the agent, countersigned by the COO. |
| L5Integrated systems test | The Facility as one system, under simulated IT load at design density, through a scripted sequence of faults and a sustained run. Full utility failure to generator and back. Black-building start from dead. Thermal ride-through across the transfer. Sequential and simultaneous plant failures. Load steps and load rejection. A continuous run at design load, including through the worst ambient window available in the test period. | Cluster availability maintained across every scripted fault, thermal envelope held throughout, and the sustained run completed with zero unplanned interruptions. Measured performance consistent with the design basis, including the PUE 1.44 peak and Tier III Standard topology. | Commissioning agent directs. Prima COO present throughout. Customer entitled to attend in full, on notice. Signed by the agent, the COO and the design engineer of record. |
Ready for service is not a date on a programme; it is the L5 certificate. No customer load is accepted, and no availability commitment takes effect, until L5 is signed. Two consequences follow, and both are deliberate.

A gate certificate is worth exactly as much as the people who signed it were present for. This section fixes who must attend, who signs, and what the customer is entitled to see.
| Level | Must attend | Signs the certificate | Customer |
|---|---|---|---|
| L1 | Commissioning agent for UPS, generators, switchgear; manufacturer's test engineer | Commissioning agent | On request |
| L2 | Installing contractor; commissioning agent verifying by sample | Agent + Facilities Manager | Records only |
| L3 | Commissioning agent; manufacturer for UPS, generators, chillers; Prima Facilities and Engineering Managers | Agent, countersigned by Prima | Records only |
| L4 | Commissioning agent; Prima Facilities, Engineering and Operations Managers | Agent, countersigned by COO | On request, may attend |
| L5 | Commissioning agent; Prima COO throughout; design engineer of record; resident shift team | Agent + COO + engineer of record | Entitled to attend in full |
The engineers who will hold the shift attend L4 and L5 as participants. This is the only period in the Facility's life when plant can be failed deliberately with no customer on it, and it is therefore the most valuable training that will ever be available. Attendance at L4 and L5 is recorded against each engineer's competence file under PRM-HR-2026-001 and counts toward the certification requirements named there.
Each gate closes with a defined set. An incomplete pack is an open gate, irrespective of whether the tests passed.
| Per test | Approved script, recorded values against criteria, pass or fail, instrument calibration references, names and signatures of those present, date and time. |
|---|---|
| Per gate | Gate certificate listing every test in scope with its result; register of open items with owner and closure date; any conditional pass stated in full. |
| At L5 | Integrated systems test report; as-built drawings updated to reflect anything found during commissioning; final settings register for protection, control and alarm set points; approved MOP set for the commissioned plant; completed drill records per section 07. |
| Handover to operations | The full pack transfers to the Operations Manager on L5 sign-off and becomes the baseline for the maintenance regime. Set points may not be changed thereafter except under change control. |
| Retention | Held for the life of the asset. Commissioning records are the only proof of the design basis once the plant has been in service for years and the people who built it have moved on. |

An emergency procedure that has never been executed is an assumption. The 17 EOPs in PRM-OPS-2026-001 are exercised at three depths, and each exercise is graded against the procedure's own stated timings — not against the impression of those present.
The shift walks the procedure aloud against a described scenario. No plant is touched. Finds missing steps, wrong contacts, ambiguous wording and unstated assumptions. Every EOP gets one on approval, before any live exercise.
The condition is induced at the control or signal level — a forced alarm, an isolated sensor, a simulated trip — without failing the plant itself. Proves detection, alarm routing, escalation and the human sequence.
The plant is actually failed and the procedure executed for real. The only depth that proves the procedure works. Restricted to the commissioning window and to planned maintenance windows thereafter.
| Grade | Meaning | Consequence |
|---|---|---|
| Pass | Executed as written, within every timing stated in the procedure, with no step found wrong or unclear. | Recorded. Next exercise falls due per the calendar. |
| Pass with observation | Outcome achieved, but a step was slow, awkward, or required interpretation not in the text. | Editorial revision of the procedure within 20 business days. No re-exercise required. |
| Fail | Outcome not achieved, a timing missed, or the procedure could not be followed as written. | Technical revision under PRM-OPS-2026-001, then re-exercise at the same depth within 30 days. Escalated to the COO. |

Every EOP is walked through in September, on approval of the emergency set. Live exercises are then concentrated into the L4 window in November and the L5 window in December — the only period in which plant can be failed deliberately with no customer on it. All 17 are exercised live or at simulation depth before service commences.

From ready for service the programme becomes a rolling annual cycle. The commitment is that every one of the 17 procedures is exercised at least once in any 12-month period, spread across quarters so that no single quarter carries a disproportionate operational risk. Live depth is restricted to agreed maintenance windows.

| Generator on load | Exercised monthly on load under PRM-MOP-ELE-004 as maintenance, independently of this calendar. The drills above test the procedure; the MOP tests the machine. |
|---|---|
| Black-building | Annual, in a planned window, with the customer notified under the Demarcation Matrix. The most disruptive exercise in the cycle and the one most often quietly dropped — it is scheduled in Q3 and does not move without COO authorisation. |
| Every shift, every year | All four shifts participate across the annual cycle. A procedure exercised only by the day shift is not exercised — the drill record names the shift, and coverage is audited. |
| Unplanned events count | Where a real incident causes an EOP to be executed, that execution is recorded as an exercise and satisfies the annual requirement for that procedure, with the incident record cross-referenced under PRM-IRP-2026-001. |
| New or revised procedure | A procedure issued at 1.0, or revised technically, is exercised at tabletop depth within 30 days of release regardless of where it sits in the calendar. |
| After any fail | Re-exercised at the same depth within 30 days, in addition to its scheduled slot. A failed drill does not consume the annual requirement. |

The programme exists to produce a body of evidence. This section states what that evidence is, when each piece first exists, how long it is held, and how the programme itself is held to account.
| Evidence | First exists | Retention |
|---|---|---|
| L1 factory acceptance certificates | Per shipment | Life of asset |
| L2 and L3 certificates with open-item registers | Per system, on installation | Life of asset |
| L4 functional performance report | Nov 2026 | Life of asset |
| L5 integrated systems test report | Dec 2026 | Life of asset |
| Drill records with grade, timings and shift | Sep 2026, then continuous | 7 years |
| Final settings register — protection, control, alarms | Dec 2026, then change-controlled | Life of asset |
| As-built drawings reconciled to commissioning | Dec 2026 | Life of asset |
| Instrument calibration certificates for test equipment | Per test campaign | 7 years |
| Programme owner | COO. Owns the gates, authorises live exercises and conditional passes, and is the only office that may move a scheduled drill. |
|---|---|
| Commissioning agent | Independent, appointed by Prima, reporting to the COO. Owns the scripts and results, not the criteria. |
| Drill execution | Operations Manager. Schedules, observes, times and grades. Escalates every fail to the COO within one business day. |
| Competence linkage | Attendance and participation are recorded against each engineer's competence file under PRM-HR-2026-001. Commissioning attendance counts toward the certification requirements named there, and a drill graded Fail is followed by targeted re-training before the re-exercise. |
| Review | The programme is reviewed annually, and after any real incident in which an EOP was executed. Review is recorded even where it results in no change, so that a current review date always exists. |

Reported to the COO on the cadence shown, and to customers and lenders on request. A measure with no owner and no reporting interval is an intention, so each carries both.
| Measure | Target | Reported |
|---|---|---|
| EOPs exercised in the rolling 12 months | 100% | Quarterly |
| Drills graded Pass or Pass with observation | ≥ 90% | Quarterly |
| Shifts having participated in the annual cycle | 4 of 4 | Annually |
| Revisions arising from drills closed in 20 business days | ≥ 90% | Quarterly |
| Scheduled drills deferred without COO authorisation | 0 | Quarterly |
| Gates cleared with an open conditional pass at RFS | 0 | At L5 |
