Construction
Verify installation, startup, controls, and functional performance in the field.
Construction is where intent meets installation. The commissioning team observes work in progress, uses standardised checklists at installation and start-up, and witnesses functional performance testing under real operating conditions.
An issues and resolution log runs throughout, tracking every discrepancy until it is corrected or formally accepted by the owner. Problems found here are still the contractor’s to fix; the same problems found after handover become the owner’s.
