Equipment commissioning

The Equipment Commissioning Checklist Ops Managers Actually Use

12 Jun · 6 min read · by the Phaselo team

Commissioning projects fail in predictable places: scope that was never frozen, vendor documentation that arrives late, and a handover that production never agreed to. The checklist below is structured as five phases. Use it as the skeleton of your project plan, then break each item into tasks with owners and dates.

Phase 1: Scope and design sign-off

Functional specification approved by operations, not just engineering.
Interface points documented: power, air, water, data, upstream and downstream equipment.
Long-lead items identified and ordered with delivery dates in the plan.
Acceptance criteria agreed in writing: throughput, quality, availability targets.
Budget approved with a contingency line, not just the vendor quote.

Phase 2: Installation readiness

Site survey complete: floor loading, access routes, laydown area.
Services available at the connection points before the equipment arrives.
Contractor inductions and permits arranged ahead of mobilisation.
Production schedule adjusted: agree the installation windows early.
Old equipment decommissioning plan, including disposal and isolation.

Phase 3: Installation and cold commissioning

Mechanical installation checked against drawings before power-up.
Electrical installation tested and tagged; isolations verified.
I/O checks: every sensor and actuator proven from the control system.
Safety systems function-tested before anything runs: guards, e-stops, interlocks.
Punch list captured as tasks with owners, not as a PDF nobody reopens.

Phase 4: Hot commissioning and performance runs

First production runs with vendor support on site.
Performance test against the acceptance criteria from Phase 1.
Operator training delivered on the running equipment and signed off.
Spares list confirmed and critical spares physically on the shelf.
Deviations tracked: every gap between specified and actual performance is an item with a status.

Phase 5: Handover

As-built documentation received and filed where maintenance can find it.
Maintenance plan loaded: schedules, procedures, and spares linked.
Warranty terms recorded with dates and claim contacts.
Formal acceptance signed by production, the people who live with the equipment.
Lessons-learned review while the project team still remembers.

Run it as a plan, not a document

A checklist in a document goes stale the day installation starts. Build it as a live project instead: each phase an Epic, each checklist line a task with an owner and a due date, progress rolling up so you always know where the project stands. Phaselo gives operations teams exactly that structure, with Gantt, board, and tree views, for $8 per user per month. Start with the free trial and copy this checklist straight into your first project.
