Data center commissioning with operations in mind

Atlas helps verify that systems are technically ready before operational handover.

Typical scope

What Atlas can cover, in full or in part, depending on your programme.

  1. 01Commissioning management
  2. 02Commissioning planning
  3. 03Commissionability reviews
  4. 04Design reviews
  5. 05Installation verification
  6. 06Functional testing
  7. 07Integrated systems testing (IST)
  8. 08Failure scenario testing
  9. 09Commissioning witness
  10. 10Defect and snag management
  11. 11Documentation verification
  12. 12Operational readiness
  13. 13Handover support

Commissioning is more than completing the tests.

It is judged by what the operator receives: demonstrated behaviour, defects taken through to closure, and infrastructure it can take over safely.

Added value

Where Atlas works within your programme

  1. Design
    Atlas layer : Technical review
  2. Installation
    Atlas layer : Commissionability · QA
  3. Testing
    Atlas layer : Test quality · evidence
  4. Integration
    Atlas layer : Interfaces · failure behaviour
  5. Handover
    Atlas layer : Operational readiness
  6. Operations

Defect closure

From testing to handover

  1. Identify
  2. Assign
  3. Correct
  4. Retest
  5. Close

Your phases and levels (L1 to L5, FPT, IST…) remain those of your own framework: Atlas adapts to it.

What Atlas brings

Five levers on the quality of your programme

  1. 01

    Early review

    Identify issues before they become test problems or operational problems.

    Can this installation actually be tested, isolated, controlled, failed safely, recovered, maintained and handed over?

    Design documentation · Sequences of operation · Control narratives · Cause and effect matrices · Commissioning strategy · Test philosophy · System interfaces · Maintainability · Operational requirements

  2. 02

    Test quality

    The objective is not to complete a script. It is to obtain evidence that the system behaves as intended.

    1. Script
    2. Execution
    3. Evidence
    4. Defect
    5. Closure

    Commissioning plan · Test scripts · Acceptance criteria · Prerequisites · Expected results · Failure scenarios · Recovery steps · Evidence capture · Defect tracking

  3. 03

    System interfaces

    In critical infrastructure, problems occur at interfaces more often than inside a single piece of equipment.

    Equipment-to-system interfaces · BMS / EPMS integration · Electrical and mechanical interaction · Controls · Alarms · Interlocks · Fire-system interfaces · Automatic sequences · Degraded modes · Recovery sequences

  4. 04

    Failure behaviour

    Verify the expected behaviour under abnormal conditions, not only in normal operation.

    Equipment failure · Utility loss · Control failure · Degraded operation · Redundancy · Automatic transfer · Recovery · Operator response

    Atlas helps verify expected behaviour; it does not guarantee the resilience of the site.

  5. 05

    Defect closure

    Commissioning value is lost when issues are only recorded and passed forward.

    1. Identify
    2. Assign
    3. Correct
    4. Retest
    5. Close

    Observations · Snags · Defects · Retests · Evidence · Closure · Residual risk

Scope is defined per engagement: independent review, reinforcement of your commissioning team, or programme steering. Atlas does not necessarily act on every point below, project by project.

Operational readiness

Can Operations safely take control of this infrastructure?

For Atlas, commissioning does not end when the test passes. This is what is examined before handover.

Documentation · As-built information · Operating procedures · Alarms · Training · Maintenance readiness · Outstanding defects · Operating limitations · System status · Handover evidence

This is the link between Verify and Operate: what has been verified must be operable. See operations and maintenance

Typical situations

How Atlas can support you

  1. 01A commissioning programme to structure or reinforce before testing.
  2. 02Integrated systems testing (IST) to prepare, execute or supervise.
  3. 03Owner representation during testing, as a witness.
  4. 04A handover to prepare while defects remain open.

Entry engagement

Independent plan and script review

Before construction or before testing, an independent look at the test strategy, scripts, acceptance criteria and interfaces: gaps ranked by priority, with recommendations.

Request this engagement

What you get

  • Commissioning plan and strategy
  • Test scripts and acceptance criteria
  • Test reports and evidence
  • Defect and snag register, with closure status
  • A verified handover file

To get started: The commissioning plan or specifications, sequences of operation and control narratives, single-line and principle diagrams, the equipment list.

Commissioning questions

Do you work within our commissioning framework?

Yes. Phases, levels (L1 to L5, FPT, IST…) and terminology vary by client and project. Atlas adapts to your framework rather than imposing one.

When should we involve you?

As early as possible: reviewing sequences, control narratives and the test strategy has the most value before construction. We can also reinforce a programme that is already under way.

What is the scope of an engagement?

It is defined with you: independent review of the strategy and scripts, reinforcement of your commissioning team, or programme steering. Atlas does not necessarily act on every point presented above.
