What to Include in a Commissioning Checklist
A commissioning checklist must be comprehensive enough to provide assurance that the system is safe to operate, yet structured enough to be completed efficiently by a field engineer. Every effective commissioning checklist includes the following sections:
Equipment Identification
Tag number, equipment description, P&ID reference, location, and revision number. This ensures every completed checklist is traceable to a specific asset.
Pre-Commissioning Checks
Mechanical completion verification — correct installation, torque checks, protective coating, cleanliness, and correct tagging. Must be signed off before live testing begins.
Functional Tests
Step-by-step testing of each function: start/stop sequences, control loops, interlocks, alarms, and trips. Each test records the actual result against the expected/design value.
Performance Verification
Measured operational parameters (flow, pressure, temperature, vibration, current) compared to design specification or datasheet values. Deviations are recorded with action taken.
Safety System Checks
Verification that all safety instrumented functions (SIFs), emergency shutdown devices, relief valves, and interlocks operate correctly at their set points.
Sign-Off Section
Separate signature blocks for the commissioning contractor, the client representative, and (where required) a third-party witness. Each signature confirms they witnessed the test.
Tip: Structure your checklist to match the commissioning sequence
Commissioning is performed in a defined sequence: mechanical completion → pre-commissioning → energisation → functional testing → performance testing → handover. Your checklist should mirror this sequence so field engineers can work through it linearly without needing to jump between sections.
Commissioning Checklist by System Type
Commissioning checklists are discipline-specific. The pre-commissioning and commissioning activities for an electrical motor are completely different from those for a control valve or a heat exchanger. Below are examples of the key checklist items for the four most common system types.
Electrical Systems
Pre-Commissioning Checks
- Cable installation and termination verification
- Insulation resistance (megger) testing
- Continuity and earth loop impedance testing
- Torque check on all connections
- Protection relay settings verification
Commissioning Tests
- Motor rotation check
- Switchgear energisation sequence
- Earth fault protection trip test
- Motor overload set point verification
- Emergency stop and interlocks functional test
Instrumentation & Control
Pre-Commissioning Checks
- Instrument installation checks (orientation, process connections)
- Cable glanding and termination inspection
- Loop drawing verification
- Power supply checks
- Initial zero and span calibration
Commissioning Tests
- Loop calibration and signal verification
- Control valve stroke test
- Alarm and trip set point testing
- SCADA/DCS point-to-point verification
- Interlock functional test
Mechanical & Rotating Equipment
Pre-Commissioning Checks
- Alignment check (shaft, coupling)
- Lubrication check (oil level, grease application)
- Bolt torque verification
- Guards and safety devices fitted
- Direction of rotation check (uncoupled)
Commissioning Tests
- Initial no-load run (check vibration, temperature, noise)
- Performance test against duty point
- Seal flush and cooling systems functional test
- Vibration measurement and recording
- Operational parameter verification (flow, pressure, temperature)
Piping & Pressure Systems
Pre-Commissioning Checks
- Hydrostatic pressure test
- Pneumatic leak test
- Flushing/blowing clean
- Reinstatement check post-flushing
- Valve position check (normally open/closed per P&ID)
Commissioning Tests
- Safety relief valve set pressure verification
- Control valve operation and positioner calibration
- Leak check at operating pressure
- Flow verification against design data
- Tightness testing of flanged joints

The Commissioning Process: How Checklists Fit In
Commissioning is the final verification phase of a construction or engineering project before systems are handed over to the client for operation. Commissioning checklists — formally known as Inspection Test Records (ITRs) — are the primary quality evidence document at each stage of this process.
1. Mechanical Completion (MC)
All construction is physically complete. MC check sheets verify equipment is installed correctly, all piping is connected, and no outstanding construction punch items remain. The MC certificate is issued when all MC check sheets are signed off.
2. Pre-Commissioning
Systems are tested in a de-energised or isolated state. Pre-commissioning check sheets cover insulation resistance tests, flushing records, hydrostatic test records, loop check records, and instrument calibration certificates.
3. Commissioning
Systems are energised and functionally tested under live conditions. Commissioning check sheets record startup sequences, interlock tests, alarm verifications, and performance test results against design data.
4. Ready for Start-Up (RFSU)
All commissioning activities are complete and checked off. The RFSU certificate is issued — based on all commissioning check sheets being signed off — confirming the system is safe and ready for operation.
Download vs Build Online: Which Is Better?
You have two options when you need a commissioning checklist template: download a generic template (Word, Excel, or PDF) and edit it manually, or use an online tool to generate a purpose-built checklist for your specific system and discipline.

Commissioning Checklists and ITR Templates
In major capital projects (oil & gas, power generation, petrochemical, infrastructure), commissioning checklists are formally structured as Inspection Test Record (ITR) templates. Each ITR covers one specific test activity for one equipment tag. The completed ITRs are assembled into a commissioning dossier — the primary handover document submitted to the client at project completion.
Checksheets.com is built specifically for this workflow. Generate ITR templates for any discipline, organise them by system or equipment tag, and export a complete commissioning pack.

FAQ
What is a commissioning checklist?
A commissioning checklist is a structured form that verifies a system or piece of equipment has been correctly installed, tested, and is ready for operation. It records test results, measured values, and pass/fail verdicts, and is signed off by the relevant parties before system handover.
What is the difference between pre-commissioning and commissioning checklists?
Pre-commissioning checklists verify mechanical completion and correct installation before energisation. Commissioning checklists then verify functional operation under live conditions — confirming the system performs to its design specification.
How do I create a commissioning checklist for electrical systems?
An electrical commissioning checklist should cover: cable installation verification, insulation resistance testing, continuity and earth loop tests, protection relay settings, motor rotation checks, functional tests of all interlocks and trips, and emergency stop verification. Checksheets.com generates a complete electrical commissioning checklist automatically.
What is a commissioning dossier?
A commissioning dossier (also called a handover pack or turnover package) is the collection of all completed commissioning checklists, ITRs, test records, and certificates assembled for a system or area. It is submitted to the client at project handover as evidence that all commissioning activities have been completed satisfactorily.
Do I need a different checklist for each discipline?
Yes. Each engineering discipline has unique commissioning activities, tests, and acceptance criteria. An electrical commissioning checklist differs significantly from a piping commissioning checklist or a mechanical equipment checklist. Using discipline-specific checklists ensures all the correct tests are performed and nothing is missed.
Can I use a commissioning checklist for HVAC systems?
Yes. HVAC commissioning checklists cover air handling unit installation checks, ductwork tightness testing, damper operation verification, temperature and flow commissioning, BMS/controls functional testing, and noise/vibration measurement. Checksheets.com generates HVAC-specific commissioning checklists.
