MC — Mechanical Completion

The stage at which construction and installation activities have been completed and equipment is ready for commissioning.

Definition

Mechanical Completion (MC) is the project milestone at which construction, fabrication, installation and verification activities have been completed in accordance with the approved design, allowing equipment or systems to be formally transferred from construction to commissioning. Mechanical Completion confirms that the installed assets are physically complete but does not indicate that they have been commissioned or placed into operational service.

Why It Matters

Mechanical Completion marks the formal handover of completed construction work to the commissioning phase.

In Practice

Mechanical Completion is typically verified through inspections, punch lists, documentation reviews and completion certificates before responsibility is transferred to the commissioning team.

Common Misuse

Mechanical Completion confirms that construction activities are complete, whereas commissioning verifies that systems perform safely and correctly under operating conditions.
