Commissioning

We provide specialist commissioning of heating, chilled water and ventilation systems for building-services projects throughout the UK.

Proving that systems perform as intended.

Commissioning is the structured process of preparing, setting to work, adjusting and verifying building-services systems before handover.

Good commissioning provides more than a set of readings. It demonstrates that the installation has been properly prepared, equipment is operating correctly, system flows have been regulated and the completed installation can achieve its intended performance.

Powell Technical Management combines practical site experience with a thorough technical approach to deliver commissioning across new-build, refurbishment and fit-out projects.

Heating & chilled water systems

Correct distribution of water throughout LTHW and CHW systems is critical to performance. Our engineers undertake system checks, flow measurement, regulation and balancing to establish the required distribution and verify performance against the available design information.

• System readiness checks
• Pump checks and setting to work
• Flow measurement
• Valve regulation
• Branch balancing
• Terminal-unit balancing
• Differential-pressure checks
• System performance verification
• Final readings and records

Ventilation commissioning

We undertake testing and balancing of ventilation systems to demonstrate that the required air quantities are being delivered throughout the installation.

• Fan checks
• Air-volume measurement
• Main and branch duct balancing
• Terminal balancing
• Grille and diffuser readings
• System pressure checks
• Performance assessment
• Final commissioning records

Testing & validation

Depending on project requirements, Powell Technical Management can also provide specialist site testing and technical investigation.

• Site validations
• Technical surveys
• System appraisals
• Environmental testing
• Acoustic monitoring
• Performance investigation
• Existing-system assessment

Our commissioning process

1. Review: establish design information, required performance and commissioning requirements.
2. Inspect: confirm systems are complete, accessible and ready for commissioning.
3. Set to Work: check equipment operation and establish appropriate initial system conditions.
4. Balance: measure, adjust and regulate the system to achieve the required distribution.
5. Verify: assess final performance against agreed project criteria.
6. Record: provide clear commissioning information for witnessing and handover.

Good commissioning begins before testing.

Incomplete installation, inaccessible commissioning devices, poor venting, contamination and late design changes can all prevent effective commissioning. Our integrated commissioning and water-treatment experience helps identify these problems early and establish the conditions required for productive site testing.
