How to use this guide
Start broad. Verify the exact scope.
Commissioning work can range from focused testing to a broader investigation of how equipment, controls, and operating sequences perform together. The scope should identify the systems, tests, findings, corrections, and verification expected.
These listings reflect public service information. Ask whether the proposed work is commissioning, retro-commissioning, a tune-up, or implementation—and confirm who is independent from the installation contractor when that matters.
Before hiring
Questions worth asking every finalist.
- Which systems and operating sequences will be tested?
- Does the scope include issue resolution and verification, or only investigation and recommendations?
- Who will have access to controls, trend data, operators, and maintenance records?
- What final documentation and training will the building team receive?
